Researchers recreate ancient Egyptian blues

Washington State University, PULLMAN, Wash.—A team of Washington State University-led researchers has recreated the world’s oldest synthetic pigment, called Egyptian blue, which was used in ancient Egypt about 5,000 years ago.

Reporting in the journal, NPJ Heritage Science, the researchers used a variety of raw materials and heating times to develop 12 recipes for the pigments, providing useful information for archaeologists and conservation scientists who study the ancient Egyptian materials. The work was done in collaboration with Carnegie Museum of Natural History and the Smithsonian’s Museum Conservation Institute.

“We hope this will be a good case study in what science can bring to the study of our human past,” said John McCloy, first author on the paper* and director of WSU’s School of Mechanical and Materials Engineering. “The work is meant to highlight how modern science reveals hidden stories in ancient Egyptian objects.”

While Egyptian blue pigment was valued in ancient times, there is limited archaeological evidence of how it was made. It was used as a substitute for expensive minerals like turquoise or lapis lazuli and was used in painting wood, stone, and a papier-mâché-type material called cartonnage. Depending on its ingredients and processing time, its color ranges from deep blue to dull gray or green. After the Egyptians, the pigment was used by Romans, but by the Renaissance period, the knowledge of how it was made was largely forgotten.

In recent years, there has been a resurgence of interest in the pigment because it has interesting optical, magnetic, and biological properties with potential new technological applications, said McCloy. The pigment emits light in the near-infrared part of the electro-magnetic spectrum that people can’t see, which means it could be used for things like fingerprinting and counterfeit-proof inks. It also has a similar chemistry to high-temperature superconductors.

“It started out just as something that was fun to do because they asked us to produce some materials to put on display at the museum, but there’s a lot of interest in the material,” said McCloy, who, in addition to being a professor in materials science and engineering, has a master’s degree in anthropology.

To understand its makeup, the researchers, including a mineralogist and an Egyptologist, created 12 different recipes of the pigment from mixtures of silicon dioxide, copper, calcium, and sodium carbonate. They heated the material at about 1000 degrees Celsius for between one and 11 hours to replicate temperatures that would have been available for ancient artists. After cooling the samples at various rates, they studied the pigments using modern microscopy and analysis techniques that had never been used for this type of research, comparing them to two ancient Egyptian artifacts.

Egyptian blue included a variety of blue colors, depending on where they were made and their quality. The researchers found that the pigment is highly heterogeneous.

“You had some people who were making the pigment and then transporting it, and then the final use was somewhere else,” said McCloy. “One of the things that we saw was that with just small differences in the process, you got very different results.”

The researchers found that, in fact, to get the bluest color requires only about 50% of the blue-colored components.

 “It doesn’t matter what the rest of it is, which was really quite surprising to us,” said McCloy. “You can see that every single pigment particle has a bunch of stuff in it — it’s not uniform by any means.”

The samples created are currently on display at Carnegie Museum of Natural History in Pittsburgh, Pennsylvania and will become part of the museum’s new long-term gallery focused on ancient Egypt.

Ancient genomes from Yunnan China reveal Tibetan and Austroasiatic ancestry

American Association for the Advancement of Science (AAAS)—Ancient genomes from Yunnan province, China, reveal a complex and deeply rooted population history in East and Southeast Asia, including the first potential representative of a previously uncharacterized “ghost” lineage that contributed to Tibetan ancestry. The findings* from genomic analysis also point to a distinct Central Yunnan ancestry linked to early Austroasiatic populations. Collectively, this work highlights Yunnan’s pivotal role as a genetic and cultural crossroads over millennia. Ancient DNA from East and Southeast Asia reveals a complex population history beginning at least 19,000 years ago, with early splits between northern and southern East Asian lineages. However, gaps remain in understanding the genetic origins of several present-day populations. For example, Tibetan groups carry both northern East Asian ancestry and a mysterious, deeply divergent “ghost” lineage, possibly linked to archaic humans like Denisovans or an early modern Asian lineage. Similarly, the origins and spread of Austroasiatic-speaking populations across southern China and Southeast Asia remain unresolved, due in part to limited ancient DNA from key regions. Situated at the crossroads of the Tibetan Plateau, Southeast Asia, and southern China, Yunnan is the most ethnically and linguistically diverse province in modern-day China. It’s also home to early human archaeological sites that indicate a long record of occupation. Given its location and history, Yunnan’s ancient populations may hold the key to unresolved questions about the genetic history of East and Southeast Asia.

Using both targeted DNA enrichment and whole-genome shotgun sequencing, Tianyi Wang and colleagues generated genome-wide genetic data from 147 ancient individuals from Yunnan dating from 7,100 years ago to the present day. From this analysis, Wang et al. identified a 7,100-year-old individual from central Yunnan as a representative of the speculated “ghost” population that contributed to the genetic makeup of ancient and modern Tibetans. According to the authors, this lineage likely diverged from other early Asian populations over 40,000 years ago and survived in southern regions due to more stable climates during the Ice Age. Wang et al. also discovered a genetically distinct “Central Yunnan” ancestry, different from previously identified northern and southern East Asian lineages, which emerged by 5,500 years ago and contributed to modern Austroasiatic-speaking populations. Notably, this ancestry appears before the widespread adoption of agriculture in the region, suggesting that linguistic or demographic expansions may have preceded the spread of farming. The authors note that the rich genetic diversity observed in Bronze Age Yunnan mirrors the region’s current ethnic complexity and points to Yunnan as a longstanding crossroads of human migration and interaction.

Ancient tooth enamel proteins reveal hidden diversity in African Paranthropus

American Association for the Advancement of Science (AAAS)—Analysis of ancient proteins preserved in fossilized tooth enamel reveals insights into the elusive nature of Paranthropus robustus, researchers report*. The findings, which challenge long-held assumptions about this early human relative, suggest greater diversity within Paranthropus than previously recognized and support the possibility of multiple distinct species within the genus. While advances in ancient DNA (aDNA) sequencing have enabled valuable insights into the evolutionary relationships of Middle to Late Pleistocene hominins, understanding of earlier Pliocene-Pleistocene species, like Paranthropus, remains limited. This is largely because aDNA does not survive well in African hominin fossils older than 20,000 years of age. Paranthropus, which lived between 2.8 and 1 million years ago alongside other early hominins like Australopithecus and Homo, has traditionally been viewed as a single evolutionary group. However, overlapping traits between Paranthropus robustus and Australopithecus africanus have raised questions about their potential evolutionary relationship. Moreover, variation in tooth structure suggests either hidden diversity within P. robustus or the presence of multiple separate species.

In lieu of aDNA, Palesa Madupe and colleagues used ancient proteins – which can persist far longer – to investigate variation within this ancient hominin species. Using high-resolution mass spectrometry and paleoproteomics techniques, Madupe et al. analyzed dental enamel proteins from four P. robustus fossils found in South Africa’s Swartkrans cave. These fossils, dated to between 1.8–2.2 million years ago, represent some of the earliest known of this species. Protein sequence analysis revealed molecular-level variation among the P. robustus individuals, including evidence of both male and female specimens – challenging the reliability of tooth-size-based sexing and suggesting that sexual dimorphism alone cannot account for the observed diversity in the fossil record. Notably, one individual appears genetically distinct from the others, which may indicate the presence of a different Paranthropus group or reflect substantial intraspecific variation. According to the authors, these findings align with recent morphological evidence pointing to previously unrecognized taxonomic diversity within the genus, including the proposed species P. capensis.

Researchers uncover a previously unknown genetic branch of ancient hunter-gatherers local to the Colombian land bridge

American Association for the Advancement of Science (AAAS)—A new study* describes the discovery of an isolated genetic lineage of hunter-gatherers that lived 6,000 years ago in the Colombian Bogotá Altiplano. Involving genome-wide analyses of 21 ancient people, the work establishes this localized group as an independent branch of the initial South American radiation. This preceramic group shared little genetically with other populations that first peopled and then persisted in North and South America. Many studies have mapped the human journey across the Beringian land bridge and into North America. Similar work has charted people’s path throughout South America. Yet until now, few scientists had investigated DNA for clues about those who lived in between North America and South America along the Isthmo-Colombian land bridge. Now, Kim-Louise Krettek and colleagues have identified a population of preceramic hunter-gatherers with a unique gene pool in this region. They surveyed genomes of 7 hunter-gatherers from the Preceramic Period around 6,000 years ago, 9 people from the Herrera Period around 2,000 years ago, 2 people from the Los Curos area from 530 years ago, and 3 people associated with the Muisca culture from 1,200 to 520 years ago. All lived in the Bogotá Altiplano of present-day Colombia. The hunter-gatherers had a basal lineage tied to – or were genetically closer to – the initial genome associated with the first South American radiation. The group also lacked differential affinity, or shared genetic variations, with other North American groups. In general, their genetics did not overlap with either ancient or present-day South American peoples. Overall, the hunter-gatherers represent a previously unknown genetic branch of humans in the Americas, which then faded around 2,000 years ago. The genomes of the 14 people from subsequent periods were predominantly related to Central American populations. “Our study provides evidence for a major genetic turnover on the Altiplano,” Krettek et al. conclude.

Lessons from the past: Rapid globalization in Roman Anatolia mirrors the modern Great Acceleration

American Association for the Advancement of Science (AAAS)—By poring through ancient coin records and pollen data, researchers have reconstructed how the Roman conquest of Anatolia (modern-day Turkey) led to profound economic and environmental changes that mirror those seen with modern civilization. The new study sheds light on a unique period of globalization almost two millennia in the past, and could guide efforts to study the stability and future of our own increasingly interconnected world. As the Roman Republic conquered the Mediterranean world, its rulers began incorporating territories far away from Italy. One of its largest prizes was western Anatolia, which was home to various Greek city-states that were subsumed into the republic in the late 2nd century BCE. Acting as a bridge between East and West, Anatolia developed rapidly after the Roman conquest. It would become one of the empire’s most important provinces and would remain a core territory for the Eastern Romans even as the Western Empire fragmented in the 5th century CE. Mustafa Doğan and colleagues point out that the development of Roman Anatolia offers an excellent model for the Great Acceleration, or the profound socioeconomic changes linked to modern civilization and its impact on the planet. They examined a database of ancient coins and applied social analysis, finding that Anatolian cities such as Tripolis became increasingly interconnected with regional trade networks and imperial infrastructure. The team also studied fossilized pollen from Buldan Yayla Lake in western Turkey, located close to Tripolis. This revealed an exponential surge in olive pollen and a drop in other tree pollens after the Roman conquest, suggesting that native forests were quickly replaced by large-scale olive tree plantations within a century. The team linked other shifts in olive and cereal pollens to later economic transformations and events such as the growth of Constantinople in the 4th century CE. Ultimately, pollen data indicated that both crops disappeared in the 7th century CE and were replaced by regrowing forests, which coincided with the devastating war between the Eastern Empire and Sassanid Persia and the gradual disintegration of the Roman world.

Oldest whale bone tools discovered

Universitat Autonoma de Barcelona—Humans were making tools from whale bones as far back as 20,000 years ago, according to a study conducted by scientists from the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB), the French National Centre for Scientific Research (CNRS), and the University of British Columbia. This discovery broadens our understanding of early human use of whale remains and offers valuable insight into the marine ecology of the time. 

Whales, the largest animals on Earth, were an important source of food and materials such as oil and bone. For this reason, they are believed to have played a key role in the survival of many coastal human groups. However, tracing the origins of human-whale interactions is challenging, as coastal archaeological sites are especially fragile and vulnerable to rising sea levels, making it difficult to preserve evidence of early human-marine mammal relationships. 

 The research, led by Jean-Marc Pétillon (CNRS) along with ICTA-UAB scientist Krista McGrath and published in Nature Communications, analyzes 83 bone tools excavated from sites around the Bay of Biscay in Spain, along with 90 additional bones from Santa Catalina Cave, also located in the province of Biscay. The authors used mass spectrometry and radiocarbon dating to identify the species and age of the samples. 

“Our study reveals that the bones came from at least five species of large whales, the oldest of which date to approximately 19,000–20,000 years ago. These represent some of the earliest known evidence of humans using whale remains as tools”, says Jean-Marc Pétillon, senior author of the research. 

According to Krista McGrath, leading author of the paper, “ZooMS is a powerful technique for investigating past sea mammal diversity, particularly when diagnostic morphometric elements are missing from bone remains and objects, which is often the case for bone artifacts. We managed to identify species such as sperm whales, fin whales, blue whales, all still present in the Bay of Biscay today, as well as grey whales, a species now mostly restricted to the North Pacific and Arctic Oceans”. 

In addition, chemical data extracted from the bones suggest that the feeding habits of these ancient whales differed slightly from those of their modern counterparts, pointing to potential changes in behavior or the marine environment. Overall, this discovery not only enhances our understanding of early human use of whale remains but also sheds light on the role whales played in past ecosystems.

Habitat and humans shaped sloth evolution and extinction

American Association for the Advancement of Science (AAAS)—Ancient sloths ranged in size from tiny climbers to ground-dwelling giants. Now, researchers report this body size diversity was largely shaped by sloths’ habitats, and that these animals’ precipitous decline was likely a result of increasing human pressures, which also triggered the extinction of the large-bodied ground-dwelling animals. Today’s small arboreal sloths are the last remnants of a once-diverse group, surviving likely because they inhabited secluded forest canopies and avoided direct human pressures, say the authors. While only two small, tree-dwelling genera survive today – confined largely to the tropical rainforests of South and Central America – sloths (Folivora) represent a once-diverse, abundant, and widespread lineage of American mammals. During the late Cenozoic, more than 100 genera of sloths occupied a wide range of sizes and habitats, living across the Americas. Some terrestrial sloth species stood upwards of six meters tall and weighed several tons. However, by the end of the Pleistocene, the majority of these animals became extinct.

Alberto Boscaini and colleagues investigated the drivers behind the expansion and decline of body size variation in sloths over the past 35 million years, culminating in the eventual rapid collapse of the group. By combining fossil measurements, DNA and protein sequences, and advanced evolutionary modeling, Boscaini et al. reconstructed sloth evolutionary history across 67 genera and tested whether evolutionary changes in size were linked to habitat, diet, climate, predation, or other ecological pressures. The findings show that habitat preference – whether sloths lived in trees or on the ground – was the dominant factor shaping their body size evolution. Early sloths were large, ground-dwelling grazers. But transitions to tree-dwelling forms with smaller body sizes occurred multiple times, especially as open landscapes expanded. Gigantism evolved independently in several lineages, reflecting adaptive responses to cooling climates and ecological pressures. Yet, despite thriving for tens of millions of years, with body size diversity peaking in the Pleistocene, sloths experienced a sudden and dramatic decline beginning around 15,000 years ago. These declines do not align with the climatic changes of the time, but instead with the arrival of humans in the Americas. According to Boscaini et al., evidence suggests that human hunting drove the extinction of large-bodied terrestrial sloths.

Archaeologist sailing like a Viking makes unexpected discoveries

Lund University—Archaeologist Greer Jarrett at Lund University in Sweden has been sailing in the footsteps of Vikings for three years. He can now show that the Vikings sailed farther away from Scandinavia, and took routes farther from land, than was previously believed to have been possible. In his latest study, he has found evidence of a decentralized network of ports, located on islands and peninsulas, which probably played a central role in trade and travel in the Viking era.  

The sailing boat – an open, square-rigged clinker boat similar to the boats used during the Viking Age (800-1050 AD) – travelled from Trondheim up to the Arctic Circle and back in 2022. Since then, Greer Jarrett and his team have sailed over 5,000 kilometers along Viking trade routes (see map). His research shows that the likely routes of the Vikings took them farther from land than previously thought. 

“I can show that this type of boat sails well on open water, in tough conditions. But navigating close to land and in the fjords sometimes presents challenges that are just as great, but not as obvious. Underwater currents and katabatic winds blowing down from mountain slopes, for example,” says Greer Jarrett, a doctoral student in archaeology at Lund University.

Jarrett’s research trips have not been without risks. When the yard holding up the mainsail snapped off the coast of Norway, the crew were forced to improvise to save themselves from distress. 

“The cold in the Lofoten Islands was a challenge. Our hands really suffered. At that point I realized just how crucial it is to have a good crew,” says Greer Jarrett.

Has interviewed Norwegian seafarers

Jarrett has also tested the boat’s capabilities on the open sea, sailing both the Kattegat and the Baltic Sea. Despite the lack of a deep-draught keel, Jarrett says the boats are surprisingly stable.  

In a previously published paper, Jarrett and his colleagues have shown that in the Middle Ages it was possible for Greenlanders to travel to remote parts of the Arctic in search of walrus tusks using this type of boat.    

To identify specific Viking routes, Jarrett also interviewed sailors and fishermen about the routes traditionally used in the 19th and early 20th centuries, when sailing boats without engines were still common in Norway. 

“I used the experience of my own journeys and the sailors’ traditional knowledge to reconstruct possible Viking Age sailing routes.”

Stories helped Vikings to navigate

The Vikings did not navigate by map, compass or sextant. Instead, they used “mental maps” where memories and experiences played a crucial role. They also used myths linked to various coastal landmarks. 

“Examples include Viking stories about the islands Torghatten, Hestmona and Skrova off the Norwegian coast. The stories serve to remind sailors of the dangers surrounding these places, or of their importance as navigation marks.” 

These preserved myths are the last remnants of what must once have been a landscape steeped in stories. Jarrett calls this a “Maritime Cultural Mindscape”. Small islets, skerries and reefs were all part of a web of stories that helped the Vikings navigate through the landscape; and that were passed down through generations of seafarers. 

Possible Viking harbors identified

Through a combination of direct experience of the characteristics of the boats, and digital reconstruction of what the landscape looked like in the Viking Age, Jarrett has identified four possible Viking harbors along the Norwegian coast in his latest publication. (See image)

The locations of these ports (Jarret calls them “havens”) are farther out to sea than the major ports and hubs, known to date.

“With this type of boat, it has to be easy to get in and out of the harbor in all possible wind conditions. There must be several routes in and out. Shallow bays are not an issue because of the shallow draft of the boats. Getting far up the narrow fjords, however, is tricky. They are difficult to sail upwind with a square rig, and the boats are sensitive to katabatic winds.”

Jarrett’s hypothesis is that during the Viking Age, such small, easily accessible harbors abounded. Places where sailors could pause, rest, and meet other seafarers. 

“A lot of the time, we only know about the starting and ending points of the trade that took place during the Viking Age. Major ports, such as Bergen and Trondheim in Norway, Ribe in Denmark, and Dublin in Ireland. The thing I am interested in is what happened on the journeys between these major trading centers. My hypothesis is that this decentralized network of ports, located on small islands and peninsulas, was central to making trade efficient during the Viking Age.”  

Mast fixed with oars 

Jarrett’s research trips have faced a few challenges. On their way back from Lofoten in May 2022, the yard (mast spar) holding up the mainsail broke as they sailed through the middle of Vestfjorden. The accident happened with the vessel 25 kilometers out to sea.

“We had to lash two oars together to hold the sail, and hope that it would hold. We made it back to the harbor safely, but then we had to spend several days repairing the boat before we could sail again.” 

“On another trip, a minke whale suddenly surfaced and flapped its huge tail fin just meters from the boat.”

Jarret’s adventures have also highlighted how important relationships must have been during the Viking voyages. 

“You need a boat that can withstand all kinds of weather conditions. But if you don’t have a crew that can cooperate and put up with each other for long periods, these journeys would probably be impossible,” Jarrett concludes.

This gene variant contributed to the dietary and physiological evolution of modern humans

Cell Press—Two of the traits that set modern humans apart from non-human primates are taller stature and a higher basal metabolic rate. Publishing in the Cell Press journal Cell Genomics on May 21, researchers have identified a genetic variant that contributed to the co-evolution of these traits. This mutation seems to help people grow taller—especially when they consume a lot of meat.  

“The dietary shift from a primarily plant-based diet to increased meat consumption marks a major milestone in human evolution,” say co-corresponding authors Jin Li and He Huang of Fudan University. “Previous studies have suggested that this shift influenced many traits and phenotypes in anatomically modern humans. It is therefore not surprising that height may also have been affected.” 

The researchers used the UK Biobank, a resource of biological samples and genomic data from 500,000 people, to identify genetic correlations between height and basal metabolic rate and found more than 6,000 potential causal variants. After narrowing down the likely functional impacts of these variants, including their effect on protein sequences and gene expression, a specific regulatory variant of ACSF3 emerged as particularly promising. Further experimentation revealed that the variant, called rs34590044-A, elevates ACSF3 expression in the liver of modern humans compared to other apes.  

“In anatomically modern humans, basal metabolic rate and stature exhibit notable evolutionary divergence compared to non-human apes,” says author Shaohua Fan of Fudan University in Shanghai, China. “Although both traits, particularly height, have been extensively investigated, the evolutionary mechanisms driving these changes remain comparatively underexplored. That’s why we decided to focus on these two traits together.” 

To further validate these findings and determine how they relate to modern human traits, the team conducted detailed functional analyses of the variant and its effects on ACSF3 expression using both cellular and mouse models. Although the mechanism by which ACSF3 acts on the body is not fully understood, it appears to be localized to mitochondria, which the authors say explains its effects on metabolism. Increased expression of ACSF3 also appears to promote the formation of bone, which could contribute to increased height. 

In a mouse model fed with the essential amino acids that are characteristic of meat-based diets, the researchers also noticed that when ACSF3 was overexpressed, the “meat” diet led to both increased body length and a higher basal metabolic rate. 

The team notes that the ongoing study of global populations using a combination of approaches—including multiomics, experimental technologies, computational algorithms, and diverse collections of ancient DNA—is important for enhancing our understanding of complex evolutionary processes. 

“This research reveals the intricate interplay between the genetic, environmental, and demographic factors that have contributed to the emergence and evolution of anatomically modern humans,” Fan says. “It also has important implications understanding susceptibility and resistance in contemporary metabolic disorders like type 2 diabetes, obesity, and metabolic syndrome.” 

The researchers expect that many more traits may have co-evolved through similar mechanisms. They plan to continue investigating the genetic basis of metabolic homeostasis in human evolution, with the aim of determining how human ancestors adapted to diverse diets throughout evolutionary history.

Re-creating the sounds of an underground city

Acoustical Society of America—NEW ORLEANS, May 21, 2025 – Have you ever walked through the ruins of an ancient city and wondered what life sounded like back then? So has Sezin Nas, a researcher of interior architecture and acoustics at Istanbul Galata University.

The ancient, underground city of Derinkuyu caught Nas’s eye early on. Located in modern-day Turkey, Derinkuyu was built underground to defend against invasion, protect its citizens from harsh weather, and safely store agricultural products. At its peak, it could hold up to 20,000 people. The city spanned seven levels underground, with four main ventilation channels and over 50,000 other smaller shafts.

“There is a notable gap in the literature regarding the acoustic environment and soundscape of underground cities,” Nas said. “Studying the Derinkuyu underground city aimed to contribute both to the preservation of cultural heritage and to provide data that could inform the design of future underground urban spaces.”

“The integration of ventilation and communication functions within the same architectural elements is considered one of Derinkuyu’s most unique features,” Nas said. “This multifunctional use of the ventilation system strongly highlights the exceptional construction process of the site and plays a central role in shaping its soundscape.”

To recreate the ancient soundscape, Nas studied both the history of the city as well as its architecture. She analyzed three types of spaces — a church, a living area, and a kitchen. The room functions, sources of sounds, and even reverberations were considered when creating a 3D virtual soundscape that will eventually allow a listener to experience the sounds of the city.

Nas will present work on the soundscape of the ancient city of Derinkuyu on Wednesday, May 21, at 11:20 a.m. CT as part of the joint 188th Meeting of the Acoustical Society of America and 25th International Congress on Acoustics, running May 18-23.

“Derinkuyu underground city is considered an interior environment on an urban scale, which distinguishes it from the open-space urban soundscapes,” Nas said. “Listening to the reconstructed soundscape provides insights into how sound influenced spatial experience, communication practices, and social organization within the underground city.”

Nas saidys Derinkuyu’s soundscape can inspire the design of future underground urban spaces. She hopes that, in general, soundscapes will be used in the future as systematic tools for studying history.

“This research also highlights the role of historical sound environments as an important and often overlooked component of cultural heritage​,” Nas said.

Lost and Found: The Evidence for the Lost Colony

What follows is a reprise of the previously published article about the historic 16th century “lost colony” of Roanoke, North Carolina, America’s first, albeit unsuccessful, British colony which famously disappeared almost without a trace years before the founding of Jamestown, Virginia. This article also includes the latest arguable evidence more recently released, bearing on the final location of at least some of the lost inhabitants of the colony.

 

Best known for fishing and as a popular vacation destination for tourists, Hatteras Island snakes down a long 42 miles beginning just beyond the southern end of the bustling northern Outer Banks vacation communities of Nags Head, Kill Devil Hills and Kitty Hawk, just off the coast of North Carolina. Constituting the greater part of the Cape Hatteras National Seashore, it is far less populated and commercial than its adjoining Outer Banks neighbors to the north. Traveling south, I drove a seemingly endless, quiet, almost pristine ribbon of sand, with a view of the Atlantic Ocean waves crashing against it to the east on the left and the Pamlico Sound lapping up against it to the west on the right. I encountered almost nobody along the way. The ocean shelf just beyond the beaches is a virtual graveyard of shipwrecks, accumulated over the centuries on a stormy, watery stage that historically also saw the likes of Edward Teach, otherwise infamously known as Blackbeard the Pirate. Today, every summer, some discriminating vacationers avoid the crowds of the beach communities in the north and rent their getaway homes and cottages in or near the island’s tiny towns of Rodanthe, Waves, Salvo, Avon, Buxton, Frisco, and Hatteras Village. But in recent years, despite its quiet, off-the-beaten-path character, something quite extraordinary has been happening on Hatteras. At its far southern end, near the communities of Frisco, Buxton and Hatteras Village, teams composed of students and local volunteers, led by a U.K. archaeologist from the University of Bristol, have been digging into the soil sediments to uncover the island’s history—a history that may have a profound impact on solving a 433-year-old cold case mystery.

For Scott Dawson, a teacher, firefighter and EMT in his early 40’s, it would be no exaggeration to say that this has been the adventure of a lifetime. Dawson is deeply connected to the island. His family roots here go back over three hundred years into the 17th century. Over the years his passionate interest in the history and archaeology of the island has led him to dive intensely into the historic documents that underpin the real story of the indigenous Native American inhabitants of Hatteras—the Croatoan—and the earliest British newcomers who first came to explore and settle the region over 430 years ago. That story happened over 20 years before colonists set foot on what became Jamestown in present-day southern Virginia. Now, as founder and President of the non-profit Croatoan Archaeological Society, he and the society’s membership have played a key role in archaeological investigations related to that earliest colony under the direction of the University of Bristol’s Dr. Mark Horton.

When I initially spoke with Dawson about the investigations, I was in the process of reading his book, The Lost Colony and Hatteras Island, and the fascinating artifact discoveries from Horton’s excavations he described within. I already knew the story of the famous ‘lost colony’ from my own readings, so I did what all too many people in my position did—skip immediately to the second part of his book, which related in detail the story about the latest artifact findings that had commanded so much attention from the popular press in recent years. 

Before I could get very far in our conversation, he stopped me.

“Did you read Part 1 of the book?”, he asked.

With a sense of embarrassment, I answered him. “No.”

And that is where the entire direction of the discussion changed. “That’s a common mistake,” he said. “In order to really understand the significance of our finds, you need to understand the true history behind them. Most people who have read about the Croatoan and the lost colony think they know the story. But they don’t. What we have learned in school is not accurate.”

Dawson knows this because he was exposed to the same misinformation as a child growing up on the island—until he decided to really dig for the truth by going to the primary first-hand accounts and historic records.

Understanding what the latest finds mean requires going back to the historic backdrop that defined their significance………

Raleigh’s Chartered Voyages

Written history tells us that it was on the shores of the Outer Banks where the very beginnings of English colonization took place. And though far from the Elizabethan England of its time, these initial explorations and attempts owe their inception in large measure to the geopolitics, culture and economic enterprise of the broader European 16th century stage. Queen Elizabeth I and her England, with its upstart naval prowess, were challenging Spain’s undisputed position as the world’s preeminent naval power. News of Spain’s solid and strengthening foothold in the New World and the vast new resources—especially gold—that flowed from it, quickly caught the attention of the Queen and her chief playmakers—men like the favored and influential courtier Sir Walter Raleigh.

Keen to make England the most powerful monarchy of Europe, the Virgin Queen and Raleigh knew that enlarging the royal treasury and expanding the kingdom’s economy was key. Steeped in the politics of the times, they aimed to explore the New World and establish colonies to stake England’s claim and to also act as a springboard for launching raids on the Spanish West Indies and Spain’s treasure fleets. The Queen granted Raleigh a royal charter, authorizing him to explore, colonize, and control any “remote, heathen and barbarous lands, countries, and territories, not actually possessed of any Christian Prince, or inhabited by Christian People,” in return for a portion of all the gold and silver that might be acquired there.* Simultaneously, while navigating the currents of the Atlantic from England to the Caribbean and up North America’s eastern seaboard of what is today the United States, the Queen’s privateers would, and did, aggressively encounter and loot the Spanish treasure ships as they sailed in return from their conquered and established sources in the Americas. But there was another side to England’s design in this venture. The English sought to undermine the Spanish foothold among the Native Americans, who the Spanish had systematically and cruelly subjugated, plundered and murdered ever since the Christopher Columbus voyages, as a means of attaining their desired preeminence in the new-found lands. Known as the “Elizabethan Model” for colonization, it was a vision of conquest through befriending and trading with the natives, as opposed to domination and subjugation. The concept was first espoused and advanced by the Queen’s preeminent historian Richard Hakluyt in his Discourse Concerning Western Planting, published in 1584. This approach was immediately and officially adopted as a means for English colonization. Hakluyt, also a geographer, became a principal member of the first voyages. And as will be seen later, the “Elizabethan Model” proved key to the survivability of the early colonists.

With that, Raleigh financed, solicited investors, and organized the first English expeditions. It was first and foremost an economic and military venture, as well as a vanguard undertaking in scientific research. The initial two expeditions, the first a reconnaissance mission headed by Philip Amadas and Arthur Barlowe, and the second a military mission commanded by Sir Richard Grenville, which were launched in 1584 and 1585 respectively, explored primarily Croatoan (today’s Hatteras Island). The expeditions were fruitful, bringing back knowledge of the resources and inhabitants of the newly found land. Discovered and documented in detail through notes, watercolors and drawings by expedition artist, cartographer and explorer John White and expedition scientist Thomas Harriot, the earliest expeditions produced for the first time a picture of “the new found land of Virginia,” and of “the commodities and of the nature and manners of the natural inhabitants” for Raleigh and the expedition’s gentlemen British investors—and perhaps more importantly, from the Crown’s perspective, rumors of gold and a passage to the South Sea.* Equally important, friendly relations were established with the natives, of whom the famous Manteo and Wanchese were leading members, voyaging back to England with Grenville to visit as arguably America’s first Native American ambassadors. At the same time, however, acts perpetrated by the military expedition of 1585 saw the making of new enemies among the native tribes, especially the Secotan, the repercussions of which would continue to flow through the dynamics of subsequent ventures and relationships. This could explain at least in part why Wanchese was suspicious of the English. He ended his relationship with the English, but Manteo and others of his tribe remained staunch friends and allies. Thus, though the returns from the first two reconnaissance missions were mixed, it was enough in the beginning to incentivize and outfit a civilian expedition to permanently colonize the new territory with a start-up group of 118 men, women, and children. The objective was to find a deep harbor in the Chesapeake Bay area to establish a port town, and to stop briefly at Roanoke Island to retrieve 15 soldiers left on the island by the 1585 expedition. Circumstances, however, proved to alter the original plans and the colonists ended up remaining on Roanoke.

__________________________________

Veteran explorer John White was commissioned as the expedition’s leader and colony governor. In addition to the enormous responsibility for the welfare and protection of friends and families under his command, his stake in the mission was also deeply personal—along with him came his daughter Ellinor and son-in-law Ananias Dare. It was an unprecedented experiment in English civilian colonization on North American soil.

But, as it turned out, the effort was short-lived. After six weeks, White left the colony to return to England for much-needed supplies and reinforcements, leaving behind the bulk of the group, including his daughter Ellinor, son-in-law Ananias, and new granddaughter Virginia, the first English person to be born on American soil, to thrive as best they could until his return.

A return that wouldn’t occur for another three years.

The Queen needed every ship she could muster to defend England against the impending Spanish threat, and that, along with other complicating circumstances, locked White into a furiously frustrating wait until resources could finally be made available for the return trip.

Finally, in the year 1590, White stepped back onto Roanoke Island and into the site of the settlement on August 18, serendipitously coinciding with the third birthday of his granddaughter, Virginia. But there was no birthday celebration, for as White and his party could see, not a single settler remained.

“We passed toward the place where they were left in sundry houses,” White wrote in his account, “but we found the houses taken down, and the place very strongly enclosed with a high palisado of great trees, with cortynes and flankers very fort-like, and one of the chief trees or posts at the right side of the entrance had the bark taken off, and 5 feet from the ground in fair capital letters was [en]graven CROATOAN without any cross or sign of distress…..”**

White and the settlers had agreed that a cross symbol would be engraved if the settlers had encountered trouble or distress before, or as the cause for leaving, should they have to abandon the settlement. Clearly from the lack of such signage, all seemed to be well. Engraved into the tree post was ‘CROATOAN’, the name of a native group. Had the colonists gone to live with the natives? To White, this would make perfect sense. Manteo, who was left with the 1587 colonists after his return from England, was a great friend and asset to the colonists. He was a critical link to the Croatoan, the group of natives with whom the early explorers and colonists had already established a mutually beneficial symbiotic relationship, and White likely knew that he would be critical to the colony’s survival during his absence. Moreover, White knew where the Croatoan lived—on the island known today as Hatteras. 

White and his party then sailed south toward Hatteras. But a violent storm drove his ship out to sea. The attempt was abandoned and he returned to England, never to return again.

One can only imagine White’s heartbreak and the enduring haunt that likely plagued the rest of his days. His last years are lost to history, but in a letter he wrote to Hakluyt, who wrote about the early English experience in America, he summed up his final trip with the words “as luckless to many, as sinister to myself”.   

Needless to say, the fate and whereabouts of the “lost colony”, as it came to be called in the popular literature, has been the subject of historical and archaeological investigation for many decades. But the story and mysteries of the first English settlement go well beyond the “lost colony”, and archaeologists and historians have been busy, off and on and as resources have allowed, conducting research to find the answers.

The search began on the north end of Roanoke Island, where some surface features and finds gave clues to the past presence of the first colony.

The Elusive Settlement

Edward “Clay” Swindell, who is the Mid-Atlantic Regional Archaeologist for the U.S. Navy, led me down narrow paths in a thicket of woods within what is today the Fort Raleigh National Historic Site area. Swindell has been a key member of a team that has recently uncovered artifacts that could give new clues about the final whereabouts of at least some of the members of the lost colony. But here, in these woods on the Island of Roanoke, North Carolina, he guides me to four places where scientists over the decades have unearthed some tantalizing traces of this first English presence in America.

One such place is the famous earthwork “fort”, the most prominent and visible feature on the historical landscape surrounding the Fort Raleigh National Historic Site visitor center. It was in this immediate area where the first full professional excavations on the island began under the direction of National Park Service archaeologist Jean “Pinky” Harrington in 1947 and 1948. What he excavated then, however, was a faint physical reminder of what once stood here. Visitors today see the reconstructed earthwork, actually constructed in the 1950’s, the way researchers and archaeologists suggest the “fort” may have appeared in its day. For years, historians and archaeologists have suggested that the simple earthwork sconce, or ‘fort’, served as the major defensive function for the early colonists, featuring perhaps the placement of cannon directed to the nearby shoreline to protect the main colony from potential Spanish attack or advances. But today archaeologists, including Swindell, disagree with that scenario.

“It’s just too far from the shoreline for that to work,” he says. “It wouldn’t make sense.”

The shoreline has changed over time since the late 16th century. But even given the original shoreline, the distance would have been too great for the fort placement to make sense. Swindell suggests that the earthwork may have been constructed as a quickly-raised earthen sconce to defend or protect an element of the early colony from nearby natives, known to be living in an established village just north of the location—or that it may have served some purpose other than defense of the colony from threats from the sea. Harrington and his team uncovered musket balls, sherds of small crucibles, olive jars, German jettons, and copper nuggets from the earthwork site. Further excavations just west of the earthwork in 1982 and 1983 by the Southeast Archaeological Center of the National Park Service also revealed similar Elizabethan period artifacts, including sherds of crucibles, more Normandy flasks, and tin-glazed ointment pots. And most recently, in 2010, ground-truthing excavations connected to a 2008-2009 Radar Tomography survey uncovered a spread of charcoal. More telling was Harrington’s excavation in 1965, including later excavations by the late Ivor Noël Hume of the Colonial Willamsburg Foundation, which revealed another adjacent site, defined by a nine-foot-square line of postmolds (dark soil where wooden posts in the ground had long rotted away) and a one-foot-deep sunken floor that featured three pits. One of the pits contained bricks, some of which were modified, 16 sherds of a Normandy flask, and native pottery. The consensus among archaeologists now suggests that this site was Thomas Harriot’s “workshop” or “science center”, a place where he, as the expedition ‘scientist’, conducted work to extract minerals and other resources – a metallurgical workshop of sorts. The charcoal feature at the earthwork uncovered in the 2010 excavations has also since been identified as fuel made by Harriot and his workmen, likely during the 1585 expedition. The archaeology has shown that this workshop site may actually have preceded the earthwork. So it is not an altogether unsupportable suggestion that the earthwork feature might have been designed to protect the workshop due to worsening relations with the neighboring natives.

Walking further north, Swindell leads me to a place where, in 2008, 2009, and 2010, archaeologists uncovered more artifacts. As we swat mosquitoes from our faces, he points and delineates the area where the excavations took place. One would hardly know any excavation had ever taken place here. Tucked deep in the woods along a nature trail, it appeared virtually untouched by the human hand. But in 2008 archaeologists had to dig 3 feet down through sand in this place before they could reach any signs of past cultural activity. The dune build-up over time had covered over the original late 16th century surface. Today the place is known as the ‘Harriot Woods’ site, where excavators uncovered two cache pits containing European artifacts, including a necklace made of diamond-shaped copper plates (a likely trade item of high value to the local Algonquian natives of the time), copper aiglets typically used to lace up Elizabethan clothing, a fragment of lace, and glass Venetian beads (also a valued trade item among the local Indians). Further excavation at the site revealed a slot trench feature that was identified as evidence of a palisade fence that ran northward toward the shoreline. Radiocarbon dating of organic material found at the site indicated a date range of 1540 – 1640 AD.

Was this, along with the earthwork and the ‘science center’ site, part of the remains of the main settlement and fort documented in the historical accounts?

Archaeologists have their doubts.

“None of the artifacts or features here are evidence of domestic activity,” says Swindell.  “Harrington’s work, Hume’s work, and our (more recent) work didn’t show any kind of habitation here (that would be characteristic of a domestic settlement, such as at Jamestown).” And even the earthwork, interpreted as a defensive feature, would not be substantial enough to be considered a fort of the type that the colony would need for overall defense. Now, archaeologists question the earlier suppositions that the main settlement site has been found. Nonetheless, the earthwork site and the other sites nearby clearly indicate a 16th century European presence on the island.

Much more work needs to be done before solid conclusions can be drawn, says Swindell. That work will be challenging, and part of that challenge has to do with the changing environment and the dunes. Dune formation in this area has covered the surface to the point where one must typically excavate at least several feet before reaching any cultural layers that could be identified with the colonial period. Significant shoreline erosion has been another culprit. Swindell walked me eastward along a narrow trail through the woods to a point on the shoreline. We emerged at the edge of a high sand dune bluff overlooking the shoreline. It was sculpted by the unrelenting elements of water and wind over time. Called “Barrel Beach”, this is where archaeologists recovered the lower part of a wooden barrel and a hollowed-out log in shallow water along the shore in 1982. Radiocarbon-dated to the late 16th century, they are thought by some archaeologists to be parts of a well facility established by the colonists for access to fresh water. Here also archaeologists found Iberian olive jar sherds and a few 16th century objects, including an axe. But the point is that none of these objects would have been found at the time if it hadn’t been for the extensive, ongoing erosion of the deep dune layers along the shoreline. The erosion, in a sense, did the digging for them. Yet even this has its drawbacks. “It’s a race against time,” says Swindell. “In 2006 test units were excavated at this spot above the shoreline. Now that surface is gone. We’ve probably lost about 50 feet of shoreline due to erosion over the past decade. There was potentially an Elizabethan component here. Underwater testing has been done, but it hasn’t turned up much.” Swindell added that much of the dune accumulation, shifting and erosion we see today occurred since the early 19th century after logging removed the foliage critical for supporting and protecting the land surface from sand encroachment and erosion. It has vastly complicated efforts to investigate what lies beneath.  “In some places the sand could be as much as 10 to 12 feet above the original 16th century land surface,” he says.

So, with the doubts about the “Fort Raleigh” earthwork site as a viable candidate for the colony’s main settlement site and no evidence of artifacts or structures in the area that would signal domestic habitation, I asked Swindell where he thought the main settlement could possibly be.

We hopped into his SUV and proceeded south from the archaeological sites along highway 64 toward Manteo, the modern town on Roanoke.  “Even Pinky (long before the popular perception that the main settlement was located around or near the earthwork) suspected that the main settlement and fort was down south in the vicinity of Shallowbag Bay,” said Swindell. Manteo abuts Shallowbag Bay, home to the town’s main marina and an ideal waterfront for docking boats of a variety of capacities. The trip took only 5 minutes, and we were soon walking up a peer that jutted into the bay. We stopped at the end of the pier, at the edge of the water.

Looking at it, and comparing it to the shore area further north near the archaeological sites, it was easy to see how this would have been a much more desirable place to establish a fort and settlement.

“This is a nice, deep area for portage and docking,” he says. “The entrance to the Outer Banks is more easily accessible. You have this nice sheltered bay that better accommodates the docking of ships. So you can imagine that this would be a better place to protect your ships and to actually bring supplies in, whereas toward the north (where the current archaeological sites are) there is really no (workable) place to keep your boats and offload supplies.”     

“This isn’t a new revelation or proposal,” he continues, “but the traditional ‘Fort Raleigh’ location identified with the earthwork further north at the Park acted like a ‘red herring’, diverting attention from further exploration or consideration of this location.”

He points to another side of the bay, a concentration of condos along the shoreline. “That is one of the areas we are interested in—back in the 30’s, there was a young man who found an English sixpence in that area. Other (unprovenanced) small finds have cropped up in the area. None of them have been pursued archaeologically. We are hoping to pursue some of these leads, among other things.”

But none of this is to say that investigations at the traditional ‘Fort Raleigh’ site on the north of the island are over. 

“People think there is nothing left to find here,” says archaeologist Eric Deetz, a member of the First Colony Foundation team and lecturer at the University of North Carolina in Chapel Hill. “I don’t buy that.”

Deetz conducted a limited excavation at the workshop/science center site in 2017, re-investigating what has already been done to clarify and hopefully find answers to some outstanding questions—like uncovering and identifying postholes for missed clues to any structures. He suggests that during Harrington’s time, the excavators were not as adept at recognizing the subtle soil features that give clues to the presence of past structures. Deetz applies his years of experience from the Jamestown excavations, where they uncovered the many subtle posthole traces of the (what was thought to be long lost) palisade trenches defining James Fort, as well as its other associated structures.

“I have a dream,” he says. “And I think it’s going to come to pass.”

Like the renewed workshop/science center excavation, Deetz hopes to re-excavate many of Harrington’s old, now re-filled trenches. He shows me a site plan made of Harrington’s old trenches. He argues that the level and intensity, and thus the thoroughness, of the investigations and excavations conducted at the present-day Fort Raleigh National Historic Park area never approached the level and intensity given to the Jamestown site further north in Virginia. To illustrate this further he describes an excavation conducted in 2009-2010 that uncovered traces of a previously undetected slot trench not far from where excavators found the copper necklace and trade beads (see above). “It could be a 16th century palisade,” he speculates, “or it could be some place where they built a fence for a pigsty in 1760.” No artifacts were found that could help date the feature. However, archaeologists took soil samples from the site and sent them for OSL (Optimally Stimulated Luminescence) testing. “So if we get results indicating it could be 16th century,” he exclaims with a hopeful gleam in his eye, “then we’re off to the races.”

The North Side Story: Clues to the Lost Colony

A number of accounts and theories have been advanced over the years by historians and scholars about the fate of the ‘lost colonists’. But recent archaeological investigations may be shedding new light…………

Site X

Most archaeologists who have been involved in the ongoing research related to the first English colonial ventures on the present-day Outer Banks would say that it was unlikely that everything happened in one place. As Swindell maintains, the early expedition operations and colonial attempts likely extended beyond the single settlement locale most often depicted in popular perception. The first two voyages spent much of their time in and around Croatoan — Hatteras Island — where they initially encountered the Croatoans and established a friendly, mutually beneficial trade relationship. This is where they met Manteo, the great friend, ally, and interpreter for the early colonists, and who also famously visited with the Queen on his first voyage to England. And based on the historical accounts alone, we also know that Raleigh’s explorer-colonists were keenly interested in exploring into the interior of the land, with the prospect of claiming and settling new territory and tapping into new resources for the English Crown. The Virginea Pars map, originally drawn by John White, shows a strong interest in what is today the western Albemarle Sound. Indeed, according to White, there were plans to “remove 50 miles into the Main” from Roanoke Island. Combined with the evidence of White’s map, that would place their intentions into the lands bordering the western Albemarle Sound.

Could this be where at least some of the members of the ‘lost colony’ ended up?

Archaeologists of the First Colony Foundation think this is an explanation that cannot be dismissed. Established in 2004, the First Colony Foundation has been dedicated primarily to conducting archaeological and historical research on American beginnings related to the Elizabethan expeditions and colonies of the 1580’s. 

“Work and resources shifted away from Roanoke to the Salmon Creek area (adjacent to the western Albemarle Sound) after about 2009,” said Swindell. “With pending construction of new developments in the area, the James River Institute (a cultural resources management firm) was enlisted to survey the area. One of the sites surveyed yielded early ceramics that hinted at a European presence that appeared to predate the later colonial settlements of the area.”

The Salmon Creek site (now popularly referred to as “Site X”) was actually first identified in 2007 through an archaeological shovel test survey and later through test pits. During the surveys, archaeologists recovered a mix of Native American and early English ceramic artifacts, artifacts indicating evidence of 17th and 18th century English activity or settlement. But some of the ceramic fragments, based on later expert examination, suggested late 16th century, the time of Raleigh’s expeditions. Subsequently, the First Colony Foundation began excavations at the site in 2012—and this is where the story really took off.  It began when Brent Lane, professor of Heritage Economics at the University of North Carolina at Chapel Hill, requested the British Museum to examine White’s 1585 Virginea Pars map. The document was being used by the Foundation to inform their research and surveys in the area. “We noticed the patches on the White map and asked the British Museum to place the map (the original being located at the Museum) on a light table,” said Swindell. “This revealed a symbol or shape beneath that looked much like a fort. We had already done work in that area, so we went back to look at it again, what had been found (the early ceramics), and renewed excavations there.”

What they discovered, and the resulting interpretation of the finds, has since become a major media splash that has captured the attention of the general public and scholars alike. Beginning in 2012 and ending in 2017, with each season lasting from 7 to 10 days, archaeologists dug a total of 53 two-meter-square units over 2,250 square feet, recovering a variety of artifacts and features providing evidence mostly of a Native American, but also, to a much smaller degree, a possible European/English presence. Most noteworthy were objects, for these purposes, consisting of 40 sherds representing perhaps 6 or 7 vessels of 16th century Surrey-Hampshire Border ware; 8 sherds representing a North Devon plain baluster jar—both types of ceramic ware commonly used during the 16th and 17th centuries, the baluster jar having been typically used as a provisioning jar on sea voyages; two tenter hooks, of a type similar to that used at the early Jamestown settlement and possibly used to stretch canvas (sail cloth) to create temporary shelters or to stretch and dry animal skins; and an aiglet of the type that would have secured Elizabethan clothing, among other artifacts. The finds were generally concentrated in two of the 53-unit total excavation area. It is worth noting that the artifacts are also significant in that the earliest recorded presence of English settlement in the western Albemarle Sound area did not occur before about 1655.

So what do these finds mean? Is this evidence of the lost colony?

Perhaps. But the accounts of the Raleigh expeditions also record initial exploratory forays westward into the mainland under the leadership of Philip Amadas and Ralph Lane, leaders of the first expedition in 1585. Could the artifacts represent traces of those ventures?

The Foundation report dismisses this explanation. “The excavation of domestic table wares from several different diagnostic vessels along with other less diagnostic, but possibly contemporaneous artifacts, strongly suggests that the above mentioned European presence was of a longer duration and the activities different from those recorded for the pre-1587 English exploration of the lower Chowan River basin [as documented in the historical record].”*** 

But were the artifacts simply transported there by the Native Americans through trade? Possibly—Site X is primarily a Native American settlement site, and the native inhabitants of the time had a known, active trade network. The early colonists exchanged goods with them as needs dictated. European objects, unique and novel to the native inhabitants, were highly valued, especially items of iron, iron tools, objects made of copper, and glass Venetian beads. But, reports the Foundation team, “missing at Site X are the most common trade goods, like beads…….fragments of European pottery do occur in a few VA/NC Indian site assemblages that probably date as early as the 1660s, but they are not common, and it seems that ceramics were not routinely carried into Indian country by traders until the mid-1700s.”*** The report further notes that there are no records that indicate the presence of European traders in the area prior to 1655.  And even the Native American artifacts provide some clues, suggest the report authors — “preliminary analysis of the Colington series [a type of Native American pottery] ceramics from Site X suggests that this phase of Carolina Native American occupation occurred before the 17th century. Years of regional research informs us that this shell-tempered ware is representative of the Carolina Algonkians, or the group of Native American Indians occupying the region at the time of Elizabethan exploration in the 16th century.”***

Nonetheless,”we do not have the smoking gun,” said archaeologist Nicholas Luccketti, director of the Site X excavations. “We have no features of European-built structures. We have not found a fort. Nor do we claim to have found the main relocation site or even the main group of the 1587 Roanoke colonists” at this site.  “Quite the contrary, we believe that a small number of Roanoke colonists resided for a few years at Site X—a contention based on circumstantial evidence.”****

The First Colony Foundation team thus suggests that any habitation by Roanoke colonists at the site may have only consisted of a small surviving part of the original 1587 group, similar in vain to the accounts acquired by some Jamestown colonists from the Native Americans about the presence of other ‘white people’ in other places in the region, as later recorded on the Zuniga map of 1608. (The reported locations were placed on a map of the region, the original having been lost. But a Spanish spy sent a copy, the so-called Zuniga Map, to the Spanish court. The map indicated two locations along tributaries to the North Carolina Sounds where survivors of the 1587 colony may have resided).

Site Y

Notwithstanding the intriguing implications of Site X, it was not the only site where the First Colony Foundation uncovered some fascinating new clues. Most recently, archaeologists excavated at a location near the Chowan River, north of Site X. Here, after surveys and subsequent excavation of 72 test units, they unearthed what was identified as 16th century pottery sherds—London redware, a North Devon baluster jar, Spanish olive jars, Martincamp stoneware, Essex fine redware, and, like that found at Site X—Surrey Hampshire borderware. In all, this collection of sherds exceeded that found at Site X, and the archaeological team has concluded that the ceramic-ware finds were likely not the result of trade, in which the Natives acquired them earlier from Europeans and retained and used them for some time after. According to Lucketti, the finds suggest that there was a small contingent of colonists for a short time period at this location, much like Site X. The finds point to the possibility that the original colonists at Roanoke split up into smaller groups or families, some of them moving inland to locations like that of Site X and Y, others perhaps to Hatteras. But the jury is still out on where the main, or larger, body of the 1587 colonists may have moved or settled.   

The First Colony team is now deliberating on where to go next. The story unfolding for this region remains wide open.*****

Assuming that what the Foundation archaeologists are suggesting is true, what about the rest of the colonists? And what about the letters White observed carved into a tree and post at the abandoned 1587 colony site, which seemed to indicate that the colonists had moved to live with or near the Croatoans, who inhabited present-day Hatteras Island at the time?

Compelling new evidence unearthed on Hatteras Island may provide some clues………….

The South Side Story: Area 31DR1, The Hatteras Excavations

As is often the case with archaeology, the first leads to making discoveries sometimes begin with random findings made by locals and non-professionals. This was the case for Hatteras early in the 20th century when, for example, a mostly intact 16th century Spanish olive jar was found by local islander Eustes White; an “old sword’, along with bones, buttons, arrowheads, and a pot were reportedly found by another local Charles Miller; and a Nuremburg token (casting counter that looks like a coin and used, for example, on 16th century ships to count inventory), was found in the 1930’s and later brought to the attention of archaeologist J.C. Harrington by a Hatteras local named Tandy. Harrington was excavating (from 1947 and 1953) on Roanoke Island at the time. Reports like this also likely led to survey work by the National Park Service, which designated the island, and particularly an area near Buxton, as a location of archaeological interest —what became known as Smithsonian designated area ‘31DR1’.

To be accurate, the archaeological record on Hatteras Island, both discovered and yet undiscovered, is overwhelmingly reflective of the indigenous Native American populations that have historically inhabited the island for thousands of years, extending back deep into Paleolithic times. The most numerous finds and archaeological features uncovered thus far represent the native groups of the Late Woodland Period (AD 900 until 1650), particularly that of the Croatoan culture. This was also a time period, especially in the 17th century, when this indigenous society underwent significant social and cultural transformations through contact with the new European arrivals. The beginning of this contact period has formed the context for understanding what was happening on the island during and after the time of Raleigh’s initial exploratory and colonization efforts from 1584 to 1587.

It was in area 31DR1 where perhaps some of the most sensational finds were uncovered by archaeologist Dr. David Phelps of East Carolina University and his team during a full scale archaeological excavation beginning in 1998. Along with an abundance of both Native American and European artifacts — mostly Native American — including such objects as lead shot, Native and European pipe fragments, nails, glass beads, copper items, bricks, ceramic ware, and glass fragments and bottles, they uncovered a late 16th century snaphouse gunlock and a well-preserved 16th century style bronze signet ring. Though no more important archaeologically speaking than the other finds, these latter two items became the ‘poster child’ finds from the excavation, garnering the attention of local and national media reporters and writers. The finds became a sensation not only because these were the ‘sexiest’ objects found, but at least in part because they were pulled from carefully recorded, stratified deposits through systematic, professionally controlled excavations — not random surface or digging finds happened upon by local adventurers or others going about their own business or hobbies. And they were clearly evidence for the presence of, or trade with, late 16th century Europeans on Hatteras Island.

Fast forward to 2007, when local heritage enthusiast and historian Scott Dawson self-published a book entitled Croatoan: Birthplace of America, which, along with word of mouth about Dawson at an event at the Festival Park in Manteo, caught the attention of attending archaeologist Dr. Mark Horton of the University of Bristol (UoB). Horton, already interested in the history of the Outer Banks as it related to the first English attempts at colonizing the Americas, connected with Dawson. A number of discussions and email exchanges later, and Horton and PhD candidate Louisa Pittman and other UoB students were on the island in November of 2009 conducting test pits and full scale excavations, with the sponsorship and help of volunteer members of the newly formed Croatoan Archaeological Society. Dawson, one of the founders and now President of the organization, was among the participants of these excavations. Within the first few years of careful and painstaking digging and recording, they encountered some intriguing new finds and, like those of the previous Phelps excavations, they generated public notice through a flurry of news and magazine articles……….

Whisperings of a Vanished World

When traveling south along NC 12, the main road or highway through the tiny town of Hatteras Village at the southern tip of Hatteras Island, it is easy to miss the little, and only, public library. It is a component of a larger set of buildings that define the town’s community center. It might typify the kind of library one would naturally expect for a community this size, except for one thing—this facility features, at least archaeologically speaking, Hatteras Island’s biggest claim to fame—artifacts that tell a story of Croatoan Native Americans who inhabited the island and built a thriving culture here centuries ago. Along with these artifacts are objects that also evidence the presence of Europeans near or among them as early as the late 16th century—the time of the ‘lost’ colony. 

I met Dawson there early one bright October morning. With masks donned (COVID-19 precautions were still in full force), he led me into the library, and more specifically, a large room facilitated to exhibit some of the “star” artifacts excavated by archaeological teams over the years. According to Dawson, these represented but a tiny fraction of the thousands of cultural and faunal finds unearthed by Horton and his mixed team of students and volunteers over recent years at several sites in the Buxton/Frisco/Hatteras Village area. It was “a ridiculously high number,” said Dawson. “Enough to fill a garage with bins—mostly bits of brick, glass, pig teeth, peach pits, pottery, pipes, little copper squares and hooks, net weights.” Consisting mostly of artifacts and other finds related to the Native American inhabitants of the island, the massive haul is now housed and managed at a storage facility in Currituck, far to the north on the North Carolina mainland. What we saw in this refitted library room was, however, according to Dawson, the really “sexy stuff”. He led me to a large, glass climate-controlled case wherein laid the star attractions of the exhibit—the late 16th century European artifacts unearthed during the Horton team’s 2012-2013 seasons. They included a silver ring—likely once belonging to a woman, given its finger size; an Elizabethan period copper aiglet (likely used at one time to secure the end of a shoe lace); a smelted copper bun, the product of smelting typically done during the European metallurgical operations performed in the area by the earliest European arrivals; a 16th century firebar, also a product of 16th century metallurgy; a 16th century brass apostle that once held gunpowder; a fragment of a 16th century Germanic stoneware jug; a 16th century Nuremberg token; a 16th century glass arrowhead, fashioned from European glass; a 16th century lead pencil and writing slate fragment featuring drawing and other clearly human-made markings; and perhaps most interesting of all—a fragment of a 16th century swept hilt rapier. Some of these objects were not typical items valued for trade by the Native inhabitants, based on what scholars know from historical documents. And aside from the type style of the individual artifacts, the excavation layer in which these artifacts were found was dated to the late 16th century—the time period of the “lost” colony—so they were likely not objects long held over from a previous time period and deposited in sediments dated to a later time. They were all located among other finds of a Croatoan village, also likely a village that flourished during the late 16th century, as the Croatoan pottery sherds found within the mix were characteristically or stylistically typical for pottery made and used by the Native Americans before the 17th century. “Almost all natives on the east coast had a particular style in the 1500s where the lip of the vessel flares out then curves in then back out so that it’s like a backwards “S” or a “z” with curves,” said Dawson. “The Native pottery in the 1600s is straighter, on the whole smaller and in my own opinion less decorative.” Moreover, added Dawson, “the big change in the 1500s vs 1600 is the absence of glass beads [a popular trade item between the Europeans and the Native Americans] and tidewater pipe bowls we find constantly in the 1600s.” 

Artifacts were not the only hints to a 16th century European presence. One of the special skills archaeologists acquire is the ability to recognize and identify the subtle changes in soil texture, color and consistency as they dig progressively down through the layers. Like shadows in the earth, the various forms of things, especially organic objects such as wood that disintegrated over time, leave behind their effects in the sediment. Horton and his team encountered and mapped numerous postholes left by the wood frames of the Croatoan houses and other structures. These postholes were typically round. But among them were larger, square postholes, as well—not a feature ever found related to Native American structures, at least in this region of the country. Dawson suggests that these were the traces of 16th century European structures/houses. And they could not have been from the first two Raleigh expeditions, which were largely military—based on historical documentation, they sojourned in this area in tent. The square postholes had to evidence a more permanent European presence. Could these have been structures built by the “lost” colony among the Croatoan villagers? 

As exciting as these artifacts are, Dawson believes that most people who come to visit this place are really ‘missing the elephant in the room’. For him, perhaps the bigger story is how an entire nation of Native Americans, the Croatoans, largely vanished from American history, forgotten in the limelight of the history that is typically taught in American schools and American history books. This needs to change, he says. The countless artifacts uncovered in the excavations provide a testament to this lost history.

Following the Tokens

This much is certain: the ongoing search for the “lost” colony’ on Hatteras Island is not over. For one thing, one find may likely open a new chapter — the Nuremberg token found by Tandy on Hatteras in the 1930’s that ended up in the hands of J.C. Harrington in the 1950’s while he worked at the early Roanoke excavations. It matched two of three almost identical tokens found on Roanoke. Moreover, another identical token was unearthed later during Horton’s Hatteras excavations in 2013. The first token found by Tandy had no provenance in terms of excavation. But the token recovered on Hatteras in 2013 had a clear provenance documented through systematic excavation. It was stratified — confirming that the token dated to the 16th century.

Horton was keenly curious about where the Tandy token was originally found on Hatteras. Doing some research on his own, fellow excavator Dawson found the answer. A copy of a report by archaeologist William Haag from previous investigations indicated the latitude in which the token was found. With this, Dawson led Horton to the general location in which the token was found by Tandy in 1938. Nowhere near the location of Horton’s recent excavations — the site of the Croatoan village — this raised another question: how did it get there, and why so far from a habitation site?

_________________________________

To Dawson and Horton’s knowledge, no excavations had ever been conducted in this area, so absence of evidence did not necessarily mean evidence of absence. Compounding things, this location was on private property, so Horton and his team had no permission and mandate to do any test digging. But as an archaeologist familiar with the array of new tools available to archaeologists today, Horton knew what to do. He employed a drone, equipped with remote sensing technology, to conduct an aerial survey of the area of the property in which the token was found. With this, Horton hoped to detect any evidence in the landscape that would provide clues to any structures or possible human activity leaving its mark in the landscape in the past. After the drone had completed its work, the data was entered into a computer for imaging.

What they found did not disappoint.

Imaging revealed evidence of a perfectly rectangular formation, a feature that could not be seen standing at ground level. It was certainly not a natural feature. It had to be human-made. Someone, at some time in the past, had created or constructed something on this ground. It was in a field at an elevated point, surrounded on three sides by woods and a good view of the sea on the remaining side. According to Dawson and Horton, this would have been an ideal strategic location for a fort or colony ‘survivors’ camp’—good for keeping a watch on the Spanish along the coast and perhaps the still hoped-for returning resupply ships with John White — and not too far from their supportive friends, the Croatoan.

I asked Dawson during our discussion at the library why he referred to this finding as a possible ‘fort’. He led me over to a table within the artifact exhibit and flipped to a blank page in the exhibit guest book. Grabbing a pen, he drew a rough outline of the image their remote sensing revealed. It was a rectangle to be sure, but on at least two of the rectangle corners he drew square extensions—resembling in principle the same bulwark features discovered at the corners of the James Fort remains unearthed much farther north at Jamestown in Virginia, though the James Fort bulwarks were round in shape. The remote sensing imaging was not clear enough to determine the presence of similar extensions on the other two corners. In addition, said Dawson, the imaging map revealed another interesting feature—possible square postholes positioned within the area encompassed by the rectangular boundary. Was this evidence for support for a large structure within the ‘fort’? One could only speculate at this point.

Though the fort hypothesis was mere speculation, Dawson felt it was worth future investigation, once permission from the landowner was obtained to explore the matter further. “This will be a future activity of our project,” said Dawson.

Finally, and most recently, in April, 2025, archaeologists uncovered large amounts of hammerscale, a flaky or spheroidal byproduct of the iron forging process, dated to the time period of the lost colonists. While the hammerscale was recovered from a location of Native American habitation, metal-working was not within the technological culture of the natives. This material and skill is known to have come with the English settlers. It is suggested as further evidence that the colonists had encountered or joined the Croatoans and were subsequently assimilated into their community.

There is still plenty of work to do analyzing, interpreting and reporting the results of past, current, and future excavations. 

The Myth of the Lost Colony

According to Dawson, archaeologists plan to return to the area during the spring of 2021 to continue the investigations. Though there is far more work to be done on Hatteras, Dawson believes that a workable hypothesis for the fate of the lost colony can already be formulated. “The lost colony is a myth created in 1937 by a play of the same name,” he explains. “When the governor [John White] returns with resupplies the colony has vanished, leaving behind no trace except for the word Croatoan carved onto a tree. In the myth no one knows what this word means. This mythology is also taught in schools and it is completely false. In reality, the colony was never lost and the word Croatoan has always been understood. Croatoan is on the maps from the time and even the latitude of the inlets is given. This is why we began to conduct archaeology on Hatteras Island, then known as Croatoan. And alas, we found them exactly where the colony indicated they had gone. This is the story of what we found, literally bringing the truth to the surface. This colony was never actually lost nor was the word Croatoan ever a mystery. The two peoples assimilated together and the archaeology demonstrates this beautifully.” 

Saying goodbye to Dawson and thanking him for his valuable time and insights, I hopped back into my car. It would be a long drive up that lonely river of sand back to Nags Head — and perhaps back again to that museum at Fort Raleigh National Historic Park on Roanoke Island, where some of the most important finds of the Roanoke excavations are still housed and exhibited. 

The story hasn’t ended. In December, 2021, a small group of volunteers, again under the direction of Horton, returned to dig near Buxton. What they uncovered was not inconsistent with the kinds of finds they have already encountered. Among them: Thousands of shards of Croatoan pottery; a grinding stone for corn; brick; animal bones and remains of shellfish; copper; iron nails; a bronze button; window glass and daub from a 16th century home structure; a dagger handle; a saker cannon ball (usually fired by a medium cannon, slightly smaller than a culverin, developed during the early 16th century and often used by the English); metal sea chest handles that had been modified into tools; dozens of pipes, both English and Croatoan; lead shot; glass beads; redware; a frizzen (part of a gunlock); and an English Tudor Rose decor that was once part of a horse bridle.

Not a bad haul, that.

 

Note: The author asked Dawson if there were plans to return again to excavate. “Yes,” he responded.  “But the main focus with all we have found over the years is to build a museum on the island to showcase it all.”

Wild orangutans show communication complexity thought to be uniquely human

University of Warwick—In groundbreaking work from The University of Warwick, researchers have found that wild orangutans vocalise with a layered complexity previously thought to be unique to human communication, suggesting a much older evolutionary origin.

Asians made humanity’s longest prehistoric migration and shaped the genetic landscape in the Americas, finds NTU Singapore-led study

Nanyang Technological University—An international genomics study led by scientists from Nanyang Technological University, Singapore (NTU Singapore) at the Singapore Centre for Environmental Life Sciences Engineering (SCELSE)andAsian School of the Environment (ASE)has shown that early Asians made humanity’s longest prehistoric migration.

These prehistoric humans, roaming the earth over a hundred thousand years ago, would have traversed more than 20,000 kilometres on foot from North Asia to the southernmost tip of South America.

This journey would have taken multiple generations of humans, taking thousands of years. In the past, land masses were also different, with ice bridging certain portions that made the route possible.

Supported by the GenomeAsia100K consortium[1], the study was published this week in Science, which analyses DNA sequence data from 1,537 individuals representing 139 diverse ethnic groups.

The study involved 48 authors from 22 institutions across Asia, Europe and the Americas.

The researchers traced an ancient migratory journey that began in Africa, proceeded through North Asia and ended at Tierra del Fuego in modern-day Argentina, which is considered the final boundary of human migration on Earth.

By comparing patterns of shared ancestry and genetic variations that accumulate over time, the team was able to trace how groups split, moved, and adapted to new environments.

These patterns allowed the team to reconstruct ancient migration routes and estimate when different populations diverged.

The reconstructed routes gave a detailed picture of how early humans reached the far edge of the Americas, and the findings suggested that this pioneering group overcame extreme environmental challenges to complete their journey across millennia.

A key insight was that these early migrants arrived at the northwestern tip of South America, where modern-day Panama meets Colombia, approximately 14,000 years ago.

From this critical point of entry, the population diverged into four major groups: one remained in the Amazon basin, while the others moved eastward to the Dry Chaco region and southward to Patagonia’s ice fields, navigating the valleys of the Andes Mountains, the highest mountain range outside of Asia.

By analysing the genetic profiles of indigenous populations in Eurasia and South America, researchers from the GenomeAsia100K project have, for the first time, mapped the unexpectedly large genetic diversity of Asia.

Understanding migration and genetic resilience

The study also sheds light on the evolutionary consequences of such a vast migration.

Associate Professor Kim Hie Lim from NTU’s Asian School of the Environmentthe study’s corresponding author, explained that the arduous journey over thousands of years had reduced the genetic diversity of the migrant population.

“Those migrants carried only a subset of the gene pool in their ancestral populations through their long journey. Thus, the reduced genetic diversity also caused a reduced diversity in immune-related genes, which can limit a population’s flexibility to fight various infectious diseases,” explained Assoc Prof Kim, a Principal Investigator at SCELSE and Vice-Director of GenomeAsia100K.

“This could explain why some Indigenous communities were more susceptible to illnesses or diseases introduced by later immigrants, such as European colonists.  Understanding how past dynamics have shaped the genetic structure of today’s current population can yield deeper insights into human genetic resilience.”

SCELSE Senior Research Fellow Dr Elena Gusareva, the study’s first author, said that these early groups settled into new ecological niches, and over hundreds of generations, their bodies and lifestyles evolved in response to the unique challenges of each region.

“Our findings highlight the extraordinary adaptability of early, diverse indigenous groups who successfully settled in vastly different environments. Using high-resolution whole-genome sequencing technology at SCELSE, we can now uncover the deep history of human migration and the genetic footprints left behind by the early settlers.”      

Importance of Asian representation in genetic studies

NTU Professor Stephan Schuster, the study’s senior author of the paper and the Scientific Director of the GenomeAsia100K consortium, said: “Our study shows that a greater diversity of human genomes is found in Asian populations, not European ones, as has long been assumed due to sampling bias in large-scale genome sequencing projects.”

“This reshapes our understanding of historical population movements and lays a stronger foundation for future research into human evolution. Our new insights underscore the importance of increasing the representation of Asian populations in genetic studies, especially as genomics plays a critical role in personalized medicine, public health, and the understanding of human evolution,” added Prof Schuster, who is the President’s Chair in Genomics at NTU’s School of Biological Sciences, and the Deputy Centre Director at SCELSE.

By tracing the impact of migration and isolation on genetic characteristics, the study offers insights into how different populations respond to diseases and how their immune systems have evolved.

The findings also help scientists better understand the genetic makeup of Native American populations and help policymakers to better protect and conserve native communities.

It also demonstrates how advanced genomic tools and global collaboration can deepen humanity’s understanding of human evolution and inform future medical and scientific breakthroughs.

Hands from two hominin species show the path to dexterity and tool use was gradual

American Association for the Advancement of Science (AAAS)—Hand remains from two ancient hominins found in South Africa have human-like finger characteristics useful for object manipulation, even though both species still regularly climbed trees, a new study* finds. However, the human-like hand features in each species – Australopithecus sediba and Homo naledi – differ from each other. The findings ultimately support the hypothesis that musculoskeletal hand evolution – a necessity for learning to use tools – was not a linear journey in Plio-Pleistocene hominins. Learning to use tools was a pivotal event in the history of the genus Homo. Until now, it’s been debated whether hominin hands lost traits adapted for climbing in trees before they developed object manipulation traits, or if manipulation and human-like dexterity emerged more gradually. Samar Syeda and colleagues examined two near-complete hand remains from these two hominins. Both had human-like traits in their fingers that differed from each other. The thumb base of A. sediba showed features that likely supported manipulation, while H. naledi’s hand had human- and Neanderthal-like features in its radial carpometacarpal joints, which connect the fingers to the carpal bones in the wrist. Each species’ hands also had traits to help them climb trees. The work shows that key traits for manipulation and tool use evolved while early humans were still climbing, suggesting that the road to human dexterity was anything but straightforward.

Provenance of obsidian artifacts at Tenochtitlan

Proceedings of the National Academy of Sciences—A study* identifies the sources of obsidian used in artifacts from the capital of the Aztec Empire. Mesoamerican societies, including the Mexica, or Aztecs, valued obsidian as a key resource for tools and ornamental or religious objects. Diego Matadamas-Gomora and colleagues explored trends in the use of obsidian at Tenochtitlan, the capital of the Mexica Empire, from around 1375 CE to 1520 CE based on analysis of 788 obsidian artifacts excavated from the Templo Mayor complex. The authors used X-ray fluorescence to analyze the geochemical composition of the artifacts, which included ritual objects and fragments of prismatic blades and flakes likely used for nonritual activities. The analysis identified the Sierra de Pachuca obsidian deposit as the source of 89% of the artifacts. Sierra de Pachuca obsidian was valued for ritual objects due to its distinctive green and gold colors, and its use remained constant throughout Tenochtitlan’s history. Nonritual objects came from diverse sources within and outside the empire, including the Tulancingo, El Paraíso, and Zacualtipán deposits in the early phases of the site. Following the consolidation of the Mexica Empire around 1430 CE, obsidian from the Otumba, Paredón, and Ucareo deposits became common. According to the authors, the findings provide insights into the dynamics of obsidian trade systems across Postclassic Mesoamerica.

The oldest wood spears are 100,000 years younger than estimated, and used by Neanderthals instead of their ancestors

American Association for the Advancement of Science (AAAS)—The oldest known wood spears are actually 100,000 years younger than previously thought, new research reveals. This updated estimate means that Neanderthals – and not their forebears – likely used the spears at what is now the Schöningen 13II-4 archaeological site. Located in modern Germany, Schöningen 13II-4 contains clues about the prehistoric “Spear Horizon,” in which Paleolithic hominins began spear hunting. Prior work first dated the site and its complete wood spears to roughly 400,000 years ago. This meant the spears would have been used by Homo heidelbergensis, likely the last common ancestor of humans and Neanderthals. However, subsequent research moved that estimate up to 300,000 years ago. Now, Jarod Hutson and colleagues have revised this estimate again, establishing the spears as just 200,000 years old. By combining results from amino acid-based geochronology of fossils with reexaminations of local chronostratigraphy from the Mid-Pleistocene, they determined that the site was active during the time of the Neanderthals, who used them for communal hunting. “Schöningen stood as an outlier among sites,” Hutson et al. write. “Our dating evidence for the ‘Spear Horizon’ corrects this mismatch and aligns the Schöningen spears within the timeframe of European Neanderthals and the Middle Paleolithic.”

Archeologists Join Geologists in the Quest to Define the Age of Humans

Deborah Barsky is a writing fellow for the Human Bridges, a researcher at the Catalan Institute of Human Paleoecology and Social Evolution, and an associate professor at the Rovira i Virgili University in Tarragona, Spain, with the Open University of Catalonia (UOC). She is the author of Human Prehistory: Exploring the Past to Understand the Future (Cambridge University Press, 2022).

The evolution of the human mind has allowed us to transcend our modern understandings of time and expand into the realm of “deep time thinking.” One example of this is the Geologic Time Scale (GTS), a human construct that traces the astrophysical events that have affected the composition and structure of the Earth since it was formed some 4.6 billion years ago.

Scientists have assembled bits and pieces of this huge temporal scale into periods of relative climatic and biotic stability based on geological and fossil data. By ordering these events sequentially in time, they have been able to reconstruct when, how, and under what conditions life emerged on the planet. Under the aegis of the International Union of Geological Sciences (IUGS), the International Commission on Stratigraphy (ICS) is charged with defining geological epochs based on fundamental changes registered in the Earth’s geological formations. The GTS is often depicted with spiraling concentric branches divided into segments representing distinct geological epochs defined by periods of relative geobiological stability.

These epochs are named, dated, and ordered, and the length of each segment is proportional to its duration relative to the other phases. As we progress toward the outer rings of the spiral, we notice that the time segments gradually become smaller, especially around 500 million years ago after the unprecedented proliferation of complex life forms that appeared during the Cambrian explosion, which accelerated the pace of global ecological changes registered in the Earth’s layers.

The emergence of the first humanoid species has been traced back to only around 7 million years ago and is placed at the extreme tip of the last branch of the spiral, underscoring how little time has passed, relatively, since our ancestors appeared on the planet. Based on global climatic data, the evolutionary story of the genus Homo has taken place throughout the Quaternary Period that began around 2.58 million years ago during the Pleistocene Epoch. This period roughly overlaps with the invention of the first breakthrough human technologies made from stone. A global warming event that began 11,650 years ago around the same time as the emergence of early sedentary civilizations in the Fertile Crescent signals the start of the Holocene Epoch, in which we currently live.

The Anthropocene (The Age of Humans) has been proposed as a new geological epoch after or within the Holocene, and, if formalized, would be the first to be introduced based on geologically observable effects of human activity on the planet. This compelling proposal spurred the establishment of the Anthropocene Working Group (AWG), which is tasked to evaluate whether the geophysical signature of human behavior is sufficient to justify placing this new epoch at the apex of the spiraling branches of the GTS. While many scientists agree on the idea in principle, a major point of contention is when exactly the Anthropocene began.

Not surprisingly, pinpointing a precise threshold when human activity caused recognizable global geological alteration has proven to be a very difficult task that geologists and archaeologists are working together to resolve. Some archaeologists consider the Anthropocene as an incremental process, whose genesis can be identified diachronically in the Earth’s strata as early as tens of thousands of years ago, when modern humans consolidated planetary dominance, appropriating and transforming landscapes and biotic resources in archaeologically detectable ways.

Anthropogenic signals, such as changes in ecosystems brought on by human overhunting of ice age megafauna, can be traced back to this period. By 10,000 years ago, plant and animal domestication boosted human ecosystem engineering as populations grew steadily through time. By around 5,000 years ago, the first urban dwellings drew swelling numbers of individuals into restricted areas, and technological innovation surged after the invention of metallurgy. Growing populations and intensified farming consumed and modified land, and animal husbandry led to increases in methane emissions traceable in the Earth’s sedimentary record.

The human imprint on the planet becomes significantly more conspicuous after the industrial age was launched in the Western world around 200 years ago, with an upsurge in carbon emissions from burning coal to feed technological development and increasing concentration of greenhouse gases driving global warming.

While viable arguments support each of these signposts along our evolutionary highway, the AWG concluded that the most suitable time to begin the Anthropocene would be in the 1950s, when the Great Acceleration sharply augmented the signs of human activity in the global geological record. This made the signs even more clearly distinguishable thanks to a wide range of indicators synchronously chronicling their symptoms, like climate deregulation, atmospheric, terrestrial, and water pollution, loss of biodiversity, excessive resource consumption, and massive land transformations.

In March 2024, the IUGS decided not to formally integrate the Anthropocene into the GTS; a verdict that has hardly quelled disagreements surrounding this matter. And there are other problems related to this issue. For example, while the existing chronostratigraphic divisions of the GTS register periods of stability lasting millions of years, the Anthropocene would be the first geological epoch to occur within only a human lifetime.

Even if we situate its beginning thousands of years before the industrial revolution, the Anthropocene sedimentary archive is currently still under formation. No matter the outcome of this fascinating planet-wide debate, the Anthropocene has indelibly entered into scientific and social discourse as the world faces many challenges posed by the unprecedented expansion of advanced human populations with unique techno-social behaviors that are now clearly linked to cataclysmic climatic events and biological genocide. It has become evident that the implications of the Anthropocene now exceed the question of its validity as a geochronological division in the Earth’s evolutionary history.

While geologists examine the end results of long-term paleoecological scenarios, archaeologists center on more recent layers that record the origins and evolution of human life (the archeosphere). Fascinating interpretations are coming out of the collaboration between geologists and archaeologists on the issue of the Anthropocene. Among these, the concept of the physical technosphere is particularly interesting since it addresses questions about how the entire mass of materials manufactured and modified by humans is becoming assimilated into the Earth system. In 2016, Jan Zalasiewicz and colleagues estimated the total mass of the physical technosphere to be a staggering 30 trillion tons, and it continues to grow, far surpassing both the volume and the diversity of the domesticated biosphere (plants and animals).

“We define the physical technosphere as consisting of technological materials within which a human component can be distinguished, with part in active use and part being a material residue. The human signature may be recognized by characteristics including form, function and composition that result from deliberate design, manufacture and processing. This includes extraction, processing and refining raw geological materials into novel forms and combinations of elements, compounds and products,” stated the article by Zalasiewicz and colleagues published in the Anthropocene Review, United Kingdom.

The study further added, “The active technosphere is made up of buildings, roads, energy supply structures, all tools, machines, and consumer goods that are currently in use or usable, together with farmlands and managed forests on land, the trawler scours and other excavations of the seafloor in the oceans, and so on. It is highly diverse in structure, with novel inanimate components including new minerals and materials… and a living part that includes crop plants and domesticated animals. Humans both produce and are sustained by (and now are dependent on) the rest of the physical technosphere.”

Although it was formed culturally because of anthropogenic agency, the technosphere combined with natural forces, has become an integral part of the functioning Earth system. It operates above and below the ground, in the seas, and even in outer space, with components interacting constantly and dynamically with the lithosphere, the biosphere, the hydrosphere, and the atmosphere.

While these other spheres have evolved over millions, or even billions of years, the technosphere—like the Anthropocene—has existed for a comparatively minute period of time. Continuously growing in pace with human demography and technological advances, the technosphere now generates so much excess waste that it cannot all be recycled back into the system, creating an imbalance in the structural relationships guiding the planet’s equilibrium and generating traceable Anthropocene deposits.

Beyond its physical aspects, the technosphere also encompasses the human social structures that enable it to function and in which all individuals play a part. Much like the synapses within the human brain or molecular systems forming the parts of a larger whole, humans constitute the individual components of the technosphere, cooperating to enable it to function while also creating the need for its existence.

“The technosphere is also manifest in the wide distribution of myriad artifacts such as needles, motors, and medicines, and by technological or technologically assisted processes like pumping and harvesting, as well as by nominally human activities that are closely tied to technological processes, such as watching television or filling out tax forms. Most such localized systems, processes and artifacts derive from, or are connected either directly or indirectly to, the globe-spanning networks of the technosphere,” stated the 2014 article by P. K. Haff, published in the Geological Society, London.

Following geological precepts and using methodologies classically applied in archaeological sciences, the imprint of human activity on the planet is gradually being defined, quantified, mapped, and categorized, while novel subjects like technospheric taxonomy are being developed to complement traditional geological and stratigraphic practices. Just like the remnants of prehistoric material culture—like stone tools or pottery sherds—the objects we produce, use, and throw away in our daily lives are transforming into technofossils that will become markers in the chronocultural framework of human evolution, providing fodder for future archaeologists.

At the generational scale, residues from polluting gases, sewage, toxic chemicals, and microplastics are melding into sedimentary layers, and artificial ground transformed by landfills, war rubble, mining, and urban settings is converted into novel anthropic geological settings with the passage of time.

There is no doubt that scarring and modification of land and sea resulting from wars, agriculture, urbanization, mining, and other human activities are being incorporated into the Earth’s geological layers. The evolution of human technologies has led our species to embark on an ongoing process that began incrementally and snowballed exponentially over the millennia, converting into the emblem of modern human heritage.

The global distribution of all human waste will be chronicled in relation to its position in sub-actual sedimentary formations that—in the not so distant future—will serve to define and classify the sequential cultural contexts of the Anthropocene.

Ancient Andes society used hallucinogens to strengthen social order

University of Florida—Two thousand years before the Inca empire dominated the Andes, a lesser-known society known as the Chavín Phenomenon shared common art, architecture, and materials throughout modern-day Peru. Through agricultural innovations, craft production, and trade, Chavín shaped a growing social order and laid the foundations for hierarchical society among the high peaks.

But one of their most powerful tools wasn’t farming. It was access to altered states of consciousness.

That’s according to a new study* that uncovered the earliest-known direct evidence of the use of psychoactive plants in the Peruvian Andes. A team of archaeologists from the University of Florida, Stanford University and South American institutions discovered ancient snuff tubes carved from hollow bones at the heart of monumental stone structures at Chavín de Huántar, a prehistoric ceremonial site in the mountains of Peru.

By conducting chemical and microscopic analyses of the snuff tubes, the researchers revealed traces of nicotine from wild relatives of tobacco and vilca bean residue, a hallucinogen related to DMT. The leaders, it seems, wielded these substances not just for personal visions but to reinforce their authority.

Unlike communal hallucinogenic use common in other ancient cultures, Chavín’s rituals were exclusive. Archaeologists discovered the snuff tubes in private chambers within massive stone structures that held only a handful of participants at a time, creating an air of mystique and control.

“Taking psychoactives was not just about seeing visions. It was part of a tightly controlled ritual, likely reserved for a select few, reinforcing the social hierarchy,” said Daniel Contreras, Ph.D., an anthropological archaeologist at UF and co-author of the new study that revealed these rituals at Chavín.

These experiences were likely profound, even terrifying. To those who inhaled, the supernatural might have felt like a force beyond comprehension. And that was precisely the point. By controlling access to these altered states, Chavín’s rulers established a potent ideology and convinced their people that their leadership was intertwined with mystical power and part of the natural order.

“The supernatural world isn’t necessarily friendly, but it’s powerful,” Contreras said. “These rituals, often enhanced by psychoactives, were compelling, transformative experiences that reinforced belief systems and social structures.”

Contreras has spent nearly thirty years studying the site as part of a team led by John Rick, Ph.D, professor emeritus at Stanford University. The team argue that these ceremonies were pivotal in shaping early class structures. Unlike forced labor societies, Chavín’s builders likely believed in the grandeur of the monuments they were constructing, persuaded by these immersive rituals.

Those rituals extended beyond the use of psychedelics. Archaeologists have also uncovered trumpets made from conch shells and chambers seemingly designed to enhance the awe-inducing musical performances.

“One of the ways that inequality was justified or naturalized was through ideology — through the creation of impressive ceremonial experiences that made people believe this whole project was a good idea,” Contreras said.

Their study was published this week in the Proceedings of the National Academy of Sciences.

The findings help solve a century-old mystery about this site, located at an elevation of 10,000 feet. Since its first excavation over a hundred years ago, Chavín has been seen as related to both earlier, more egalitarian societies and the mountain-spanning empires ruled by powerful elites that came later.

Controlled access to mystical experiences helps explain this major social transition, a finding only made possible by decades of intense excavations and advanced analytical methods.

“It’s exciting that ongoing excavations can be combined with cutting-edge archaeological science techniques to get us closer to understanding what it was like to live at this site,” Contreras said.

Ancient Magnificence: A Photographic Journey Through Ancient Akrotiri

On a clear, sunny morning in early October, I made my way from Fira, the iconic Mediterranean Greek island of Santorini’s largest town situated along the precipice of the Thera caldera. I traveled south to the location of the archaeological remains of Akrotiri. Though its remains hug the edge of land and ocean, it is now housed within a modern construction created specifically to protect the site from the elements. What archaeologists have revealed here represents only a fraction of what once constituted the entire settlement, but even so, it leaves a jaw-dropping impression of an ancient people who thrived in this place in abundance well over 3,000 years ago. It would be no exaggeration to say that this ancient city could be described as the Pompeii of Bronze Age Greece. Devastated during the massive eruption of the Thera volcano in the 16th century BCE, like the cities of Pompeii and Herculaneum in present-day Italy many centuries later, it was destroyed yet miraculously preserved, as if frozen in time. Excavated thousands of years after the Thera eruption, it has joined the world’s short-list of the most spectacular archaeological discoveries of all time.

Santorini is anciently known as Thera, and today it hosts an estimated 2 million visitors a year. As an island in the southern Aegean Sea, it lies about 120 miles southeast of the Greek mainland. It is the largest island within an archipelago of the Cyclades, a group of islands south of Greece and north of Crete. It is best known for its volcanic history, and the great, water-filled caldera that bestows the location its defining characteristic. It is also known for its many attractions as a tourist destination, but perhaps most fascinating of all are the incredible archaeological remains of the nearly 7,000-year-old maritime settlement of Akrotiri, the center of a Cycladic civilization that flourished most prominently during the 16th century BCE. Trade relations established with other Aegean cultures and civilizations that ringed the Mediterranean proved to be the engine of its growth, especially that of the copper trade. It became an important center for processing copper, based on the artifacts discovered at the site. The city prospered as a major center for at least 500 years. Excavations have revealed—along with thousands of artifacts—paved streets, an extensive drainage system, sophisticated pottery, and a masterful array of some of the earliest fresco wall paintings of the Bronze Age. In fact, the culture of Akrotiri was so sophisticated for its time that some historians and scholars have attributed the ancient city as a possible historic basis for the later legend of Plato’s lost Atlantis. The city came to its end between 1620 and 1530 BCE with the eruption of the Thera volcano. 

What follows is a photographic pictorial from the perspective of a typical visitor’s walk-through of the site. The sun’s rays penetrated the enveloping open structure that protected the remains—houses, apartments, public administrative buildings, religious spaces—providing an interesting flow of beaming light over many of the site’s details….

Centuries-old Austrian mummy found to be exceptionally well preserved thanks to unusual embalming method

Frontiers—For centuries, many cultures around the world embalmed their dead, often for religious reasons. Accordingly, embalming methods differ, but not all of them are studied equally well.

In a first report* of a previously undocumented embalming method, an international team of researchers has analyzed a mummy from a small Austrian village. Detailed analyses provided insights into little-known mummification techniques and allowed them to identify the body.

“The unusually well-preserved mummy in the church crypt of St Thomas am Blasenstein is the corps of a local parish vicar, Franz Xaver Sidler von Rosenegg, who died in 1746,” said Dr Andreas Nerlich, a pathologist at Ludwig-Maximilians-Universität and first author of the Frontiers in Medicine article. “Our investigation uncovered that the excellent preservation status came from an unusual type of embalming, achieved by stuffing the abdomen through the rectal canal with wood chips, twigs and fabric, and the addition of zinc chloride for internal drying.”

A different type of embalming

The team conducted extensive analyses, including CT scanning, focal autopsy, and radiocarbon dating. The mummy’s upper body was fully intact, whereas lower extremities and head showed considerable post-mortem decay.

During their investigation, the researchers found a variety of foreign material packed in the abdominal and pelvic cavity. Upon opening the body, the team identified wood chips from fir and spruce, fragments of branches, as well as different fabrics, including linen, hemp, and flax. All these materials were easily available at that time and in that region.

The researchers believe it is this mixture of materials that kept the mummy in such good condition. “Clearly, the wood chips, twigs, and dry fabric absorbed much of the fluid inside the abdominal cavity,” said Nerlich. Next to these absorbents, a toxicological analysis showed traces of zinc chloride, which has a strong drying effect.

This way of embalming is different to better-known methods where the body is opened to prepare it. Here, however, the embalming materials were inserted via the rectum. “This type of preservation may have been much more widespread but unrecognized in cases where ongoing postmortal decay processes may have damaged the body wall so that the manipulations would not have been realized as they were,” Nerlich pointed out.

Inside the mummy, the researchers also found a small glass sphere with holes on both ends – perhaps an application to fabric of monastic origin. Since only a single bead was found, it might have been lost during the preparation of the body.

Tracing a life

The mummy was long rumored to belong to Sidler, but the origin of these rumors is unknown. It was, however, only the current investigation that provided certainty as to its identity. “The identification of the mummy comes from our interdisciplinary analysis, especially with the radiocarbon dating, his body activity pattern, and the stable isotope pattern,” Nerlich said.

These analyses showed that the mummy died most likely aged between 35 and 45 years old and most probably between 1734 and 1780. These dates match Sidler’s life. In addition, they suggested Sidler ate a high-quality diet based on central European grains, animal products, and possibly inland fish. Towards the end of his life, he may have experienced food shortages, likely due to the War of Austrian Succession. The lack of major sign of stress on the skeleton fits the life of a priest without hard physical activity. There also was evidence of a long-term smoking habit, and lung tuberculosis towards the end of his life. 

“We have some written evidence that cadavers were ‘prepared’ for transport or elongated laying-out of the dead – although no report provides any precise description,” Nerlich concluded. “Possibly, the vicar was planned for transportation to his home abbey, which might have failed for unknown reasons.”
