Fortress on the Edge of Kingdoms

Ein Hatzeva.

In Hebrew, it means “strong spring”.

It also describes the ancient place by this name about 35 kms south of the Dead Sea.

The name says it all, because deep in this desert region, in what the ancients called the Arava, water meant everything. The natural fresh water spring made it a reason for ancient roads to converge here — a critical and welcoming oasis for traveling caravans along the spice and incense route, facilitating commerce and providing much-needed rest for weary travelers. And with this clear strategic value, it became a perfect place for expanding kingdoms to establish their presence. 

Fortresses on the Edge

Although the fresh water oasis of Ein Hatzeva has been thought by some to have possibly accommodated ancient Amorites and other wandering, nomadic peoples, it was mostly expanding commerce that transformed this tiny spot into a strategic way station on the fringe of kingdoms. It sat at the intersection of the main Arava road and the Negev-Edom road, a critical stopping point for the traveling caravans of spices and other goods and, at one time, a good location to facilitate oversight and protection of the copper mines at Faynan, near Eilat. 

And a good place to build a fort.  

Which is why Ein Hatzeva, otherwise known as Biblical Tamar*, has seen the presence of at least five succeeding major fortifications. Archaeological excavations since 1972 have uncovered at least 8 historic periods, revealing a sequence including Early Israelite, Edomite, Nabataean, Roman, Early Arab, and later occupations.

The Israelite and Judahite Fortresses

The earliest of the fortifications was constructed during the 10th century BCE. Comparatively small, some scholars and archaeologists have interpreted these Iron Age remains as one of a number of fortifications constructed throughout the land to secure the border of the united kingdom of Israel under Solomon**. But the most magnificent of the Iron Age fortifications was built somewhat later (archaeologists suggesting its construction during the 9th-8th centuries BCE), atop and around the smaller, older fortress footprint. This fortress, according to Biblical scholars, represented the might of the Kingdom of Judah, although it is not certain who among the Judahite kings was responsible for initiating its construction. Some suggest King Jehoshaphat (867 – 846 BCE), desiring an enlarged fortress as part of his policy to renew and build upon commercial ties with the rich kingdoms of present day southern Arabia to the south and east. Others suggest King Amaziah (798-769 BCE) or Uzziah (769-733 BCE). 

In any case, the enlarged fortress is considered to have been among the largest Judahite fortresses ever built, fulfilling a critical role in the Kingdom of Judah’s border defenses. Beginning in the first expansion with a 50 x 50 meter surrounding wall, it was later expanded to 100 x 100 meters, comparable in area to a town of the time. Excavations have uncovered a massive three-meter-thick casemate wall, the casemate sections filled with packed earth. Buttressing the wall was a defensive rampart. Towers were set at its corners. A four-chambered gatethouse complex (a standard feature for cities and fortifications of the period) still stands to a height of three meters in the northeastern corner of the fortress remains. Not intended by its original builders, however, part of the gate complex leans, as if, with one powerful push, one could topple it over. It is a testament to damage caused by a powerful earthquake in the mid-8th century BCE. The fortress remains also feature stores or granaries and silos for food—evidence of wheat and barley found within one of the silos—and a defensive moat. 

But as massive and imposing as the 8th century fortress was, the Judahite kingdom eventually lost control of what is today the Negev region, leaving opportunity for expansion by the neighboring Edomites and the fortress’s resulting destruction near the end of the 8th century BCE. A smaller 7th century fortress was built over the remains of the former, but it never attained the grandeur and defensive prowess that characterized the previous larger fortress.

The Four-Room House

A key feature uncovered at Ein Hatzeva was a four-room house, built during the period of the Israelite/Judahite fortifications:

Above and below: The foundation still visible, pictured here are its remains—what archaeologists have identified as a classic Israelite four-room house structure. Most houses inhabited by the Israelites during the Iron Age, beginning at the end of the 11th century BCE until about the time of the Babylonian Exile in the 6th century BCE, were designed after this floor plan pattern. It characterized the ground floor of the house, as this is the house level that could be determined through archaeological investigation. It typically featured four sections, or rooms, three of which were defined by two rows of wooden pillars arrayed through the center of the structure and functioning to divide the spaces, and the fourth ‘broadroom’ oriented across the back or rear of the three vertical rooms. This ground level typically functioned as space to stable livestock and for storage. The family, or extended family, resided on the upper level. Like any domicile even today, these houses varied in size, and were constructed either as stand-alone houses or as connected houses (ancient equivalent of the modern day townhouse). Many connected houses were constructed with the back, or broadroom, exterior wall abutting the surrounding casemate wall of a city. Walls, constructed of fieldstones and dried mud, were typically around one meter in thickness, with exterior walls often thicker. The house exteriors were likely plastered to prevent water erosion. Archaeological investigation has revealed that smaller urban houses may have been clustered, sharing exterior walls between and likely inhabited by nuclear families, whereas larger stand-alone houses, like the one illustrated here at Ein Hatzeva, belonged to wealthy or extended families of the elite. “This is the biggest Israelite house in Israel,” says Dr. DeWayne Coxon of the house at Ein Hatzeva. “It was probably the priest’s house.” Coxon is President of Blossoming Rose, the organization that curates the archaeological site at Ein Hatzeva. 

Along with the Israelite and Roman fortresses, bathhouse, and the Edomite cultic shrine, the large Israelite four-room house stands as one of the distinguishing features of the archaeological park, known as the Biblical Tamar Park, administered by Blossoming Rose on behalf of the Israel Antiquities Authority.

The Shrine

During the 7th century BCE, just north of the fortress ruins, the Edomites built a temple or cultic shrine, likely functioning to serve traders journeying from Edom to the Negev region. Excavations have revealed the foundational outlines of the structure, as well as an assemblage of broken ritual clay vessels and evidence of several stone altars, discovered in a repository within the structure. The finds include bowl-shaped incense stands on round bases, one of them featuring small clay objects in the shape of pomegranates (considered symbols of fertility), originally hanging from hooks; and anthropomorphic stands featuring human figures with decorated bowls atop their heads. 

Archaeologists and historians suggest that the shrine was probably destroyed and the ritual objects smashed during the reign of the Judahite king Josiah, who embarked on a campaign of religious reforms at the end of the 7th century BCE. The Biblical account (2 Kings 22-23) records this campaign of destruction. The shrine remains and the ritual vessels found at the site are currently exhibited at the Israel Museum in Jerusalem.

The Nabataean Fortress

Archaeologists unearthed evidence of a small Nabataean (1st century BCE – 1st century CE) fortress and temple beneath the remains of the later Roman fortress (described below). Investigators believe these structures were constructed here as part of a way station the Nabataeans established as a rest and commercial stop along their Incense road. 

The Romans

Ancient Rome’s expanding empire from the 1st century BCE through the 4th century CE saw its presence in almost every corner of the known Western world, and the attractive desert oasis of Ein Hatzeva was no exception. Because of its location along the lucrative caravan routes for transport and trade in spice and merchandise, not to mention its position relative to controlling and protecting the critical Faynan copper mines to the southeast near present-day Eilat and territorial defense against the incursion of outside nomadic tribes, the Romans quickly recognized the imperative of establishing a strategic foothold here. A large Roman fortress took shape over its gentle rise of earth and ruins, and soldiers were garrisoned here in a new fortification, the architectural remains of which have been unearthed by teams of archaeologists in recent years. Part of the massive Roman fortress has been exposed and partially restored by experts and volunteers, including a significant associated bathhouse complex.

The Biblical Tamar Park

For decades, Blossoming Rose, the organization established to administer the site of Ein Hatzeva as an archaeological park, has governed the planning and execution of activities related to the park on behalf of the Israel Antiquities Authority. Today, the site hosts volunteer groups for continuing site restoration and excavation, as well as tour groups organized by various organizations and tour leaders in the country visiting the biblically historic sites throughout the ‘Holy Land’ region. Many visitors, by arrangement, stay in rustic but comfortable accommodations while performing volunteer or other activities at the site. 

Although Ein Hatzeva, or Biblical Tamar, is off the beaten path for most typical tour groups and visitors to this historic region of the world, the site administrators and archaeologists hope that the significance of the site will continue to rise on the ‘radar screens’ of the general public and those visiting the region. Certainly the site’s finds, both monumental and small, have played an important role in helping archaeologists and historians to better understand the history and culture of the region. Indeed, according to Coxon, there are 26,000 artifacts from this site alone in the Israel Museum, one of the nation of Israel’s most visited destinations and arguably one of the world’s preeminent archaeologic museums. 

There is much more work to be done at Ein Hatzeva before the full story of its remains can be realized. With funding and a greater commitment of resources, however, the site can prospectively yield much more, including the possibility of uncovering remains from time periods pre-dating the Iron Age, or Israelite, period. More information about the site and the park can be obtained at blossomingrose.org.

Sterkfontein: A History of Evolution in the Cradle of Humanity

Jesse Holth is a freelance writer and editor with a background in archaeology, history, and science. She has previously worked with the Royal BC Museum, the University of Victoria, and World Elephant Day. Jesse has degrees in English and Anthropology, specializing in Archaeology. She is passionate about history, education, and conservation.

Few prehistoric sites can match the primacy of this site. Known to the world as Sterkfontein, it is widely regarded as one of the most important sites in the study of human evolution. A group of limestone caves located in South Africa’s Gauteng Province, the word means “strong spring.” It was declared a World Heritage Site in 2000. Archaeological excavations at the site have been ongoing for the past 80 years. Now, new finds have added to its prolific record of prehistory.

The Legacy

Famous for yielding the first fossil remains of the first adult specimen of Australopithecus africanus, discovered in 1936, Sterkfontein still remains the richest source of A. africanus specimens in the world. This early hominin, a genus important for understanding human evolution, lived in Southern Africa during the Plio-Pleistocene, between around 3 million and 2 million years ago (mya). Similar to Australopithecus afarensis, it exhibited a combination of human-like and ape-like features. Research on foot bones has demonstrated that it was bipedal, and recent studies of hand bones suggest that it was able to manufacture and use tools. 

Thousands of stone tools have also been found at Sterkfontein, including the oldest stone tools in Southern Africa. Both Oldowan cores and flakes and Acheulean stone tools are abundant at the site, dating to between 2mya and 1mya. The Oldowan tools are believed to have been made by an early Homo species, while large numbers of Early Acheulean tools at Sterkfontein are attributed to Homo ergaster. Cores, flakes, manuports, choppers, handaxes, and cleavers have all been recovered from Sterkfontein and are dated to between 1.6mya and 1.1mya. Wood and other organic materials rarely survive in the archaeological record, but the conditions at Sterkfontein allowed some 300 wooden fragments to survive. After study of the fossilized wood, researchers have been able to determine that the habitat at Sterkfontein included a combination of tropical forest and savanna habitat about 2.6mya.

But the cave system is perhaps best known for the discovery of two iconic hominin specimens. The first, nicknamed ‘Mrs. Ples’ by scientists, constitutes the most complete Australopithecus africanus skull ever discovered. Found in 1947, the fossil dates to 2.05–2.01 mya and revealed a surprising story to researchers at the time: she had a small cranial capacity, even though she walked upright, suggesting that bipedalism preceded any increase in brain size. There continues to be debate about whether Mrs. Ples is indeed a ‘Mrs.”  She could be an adolescent, and possibly even a male.

The second iconic find, nicknamed ‘Little Foot’, was discovered in 1994, from the Silberberg Grotto in the Sterkfontein cave system. The excavation of this specimen has proven to be extremely difficult, as it was embedded in the breccia, and has taken over fifteen years. There has been some debate about the classification of this individual, whether it should be considered Australopithecus africanus or a new, different species called Australopithecus prometheus. The dating of this specimen has also been controversial, and many attempts have been made to determine a definitive date. All estimates have been roughly between 3mya and 2mya, although the most recent estimates – using a new radioisotopic technique – place the date at 3.67mya. Little Foot is remarkably well preserved, but in extremely delicate condition, and is currently in the final stages of preparation. The fossil is being described for upcoming publication by the hominin research team at Sterkfontein. Publication of this rare and distinct specimen will offer much insight into early hominin morphology and evolution.

The deposits at Sterkfontein have yielded over 800 fossils, from four different hominin species: Australopithecus africanus, Australopithecus Prometheus, Paranthropus robustus, and Homo ergaster. Archaeologists have also discovered over 300,000 fossils from other animals, including primates, carnivores, bovids, small mammals, birds, elephants, and a number of extinct large animals. The diversity at Sterkfontein is unparalleled, making it a uniquely important site in both human and natural history. With a sequence of deposits ranging from 3.67mya to just 250,000 years ago, it documents the evolution of the landscape, environment, animals, and hominins. “There’s actually no other site like it, anywhere,” says Dominic Stratford, one of the lead researchers at Sterkfontein.

New Finds, New Technology

Recently, new hominin fossils were discovered in the Milner Hall chamber, deep within the Sterkfontein cave system. Scientists suggest they are most likely “early Homo” fossils – more recent than Australopithecus, but older than Homo ergaster. Stratford says they can’t be sure of the species until they find more specimens. “I am certainly planning further excavations in the Milner Hall,” he says. “There are untouched deposits that are very old and still need to be explored.” This area had previously never been investigated, as most of the excavations have historically focused on surface-exposed deposits – like the one where Mrs. Ples was found.

Now, deeper chambers continue to yield exciting, older fossils. Excavations are currently underway in the Jacovec Cavern, where preliminary finds have been made in recent months, and the Silberberg Grotto, where Little Foot was found. Researchers will also reopen some of the historical ‘surface’ excavations, to resample using new excavation and mapping techniques. The development of a new 3D GIS system will allow the consolidation of all previously discovered data – ranging from sediments and geology, to chemical and fossil data – into an integrated spatial database. The model was designed to better understand the complex history of deposits at the site, including which fossils belong with other fossils, sediments, or tools, and in what environment or time period. The use of this technology will be a first at Sterkfontein.

The framework for this new database is already in place – researchers have established control points throughout the caves, allowing mapping of any part down to millimeter resolution. Several of the chambers have been laser scanned, with this data integrated into the system. The next step will be to include all of the old fossil collections with the new discoveries. The 3D GIS database will then digitally populate the cave spaces with all the incorporated information. Stratford says this can provide answers to several of their questions. “Are more carnivores found in this area of the site than another? Are hominin teeth found more often in this part of the cave?” he wonders. If they can find a pattern showing where certain bones are found, or even bones with certain types of breakage, it may reveal how hominins were able to get into the cave.

Stratford says his goal is to make the database accessible to researchers online. “[The database] will take time as every fossil of the 300,000 strong collection needs to be carefully documented.”

The task going forward is huge, but luckily, there is a large team of international researchers and young South African post-graduates assisting with investigations at Sterkfontein. Some of the research programs focus on geological aspects of the site, or understanding of fossil contexts, but the wide range of fields being studied includes taphonomy, hominin morphology, functional morphology, sediment micromorphology, and geochemistry. Scientists are now generating an extremely large amount of data and information through the new, high resolution documentation techniques. Stratford says the 3D GIS database is crucial to placing each fossil in its correct environment and with the animals that shared this environment many millions of years ago. “[Only] then we can start to investigate, with real insight, what environmental and competitive stresses were put on the hominins,” he says. According to Stratford, this understanding will allow them to “make connections between anatomy, diet, locomotion, social structure” as well as “the opportunity to see if and how [these different hominin species] lived at the same time.”

sterkfonteinfingerbone

New hominin finger bone found at the Sterkfontein Cave. It is a very large proximal finger bone. So large, in fact, that it is significantly more robust than any other similar bone of any hominin yet found at South African plio-pleistocene sites. “It is almost complete and shows a really interesting mix of modern and archaic features. For example, the specimen is markedly curved – more curved than Homo naledi and is similarly curved to the much older species Australopithecus afarensis,” says Stratford. “The finger is similar in shape to the partial specimen from Olduvai Gorge that has been called Homo habilis, but is much larger. Overall, this specimen is unique in the South African plio-pleistocene fossil hominin record and deserves more studies,” says Stratford. Courtesy Jason Heaton, republished from Sterkfontein Caves produce two new hominin fossils.

A New Takeaway

With the innovation of microCT scanning and digital analyses, researchers at Sterkfontein are finally able to look inside the fossils at extremely high resolution without destroying them. This gives them the ability to investigate the structure of fossil bones, and what it might reveal about how prehistoric hominins and animals moved and lived. Moreover, two million years ago, the landscape of South Africa was populated by at least six different species of hominin, living in close proximity to each other. By understanding the context of fossil discoveries, we will know if this picture is simply a bias of our archaeological sampling, or whether it’s true – and perhaps answer some of our biggest questions.

Archaeologists excavate a Late Bronze Age settlement in Portugal

As Founder and Editor of Popular Archaeology Magazine, Dan is a freelance writer and journalist specializing in archaeology.  He studied anthropology and archaeology in undergraduate and graduate school and has been an active participant on archaeological excavations in the U.S. and abroad.  He is the creator and administrator of Archaeological Digs, a popular weblog about archaeological excavation and field school opportunities.  

When one thinks of Portugal historically and archaeologically, its colonial heyday typically comes to mind. Along with Spain, England, and other European powers of the 15th through 19th centuries, it had established its foothold well beyond its own borders into lands far distant. 

But there is a much more ancient Portugal — one that extends far back into the Bronze Age more than 3,000 years ago, and even further back into prehistory.   

Kate Leonard, a young archaeologist from Canada, had a brush with this more ancient heritage during the summer of 2016. Take, for example, the peculiar stone she encountered while excavating in her trench at a Late Bronze Age site in the Alentejo plain of the Beja region in the southern part of the country.

“One morning when I arrived on site the sunrise was slanting across the site and I noticed some indentations on one of the larger stones in the trench,” she explains. “As I excavated this stone it became clear that it was decorated with prehistoric cup-marks, intentionally created by someone (or multiple someone’s) and then positioned in the Late Bronze Age structural feature we were revealing. Cup-marked stones, or in Portuguese “rochas com covinhas” – or just “covinhas” for short –are a type of prehistoric decorated stone found across western Europe. They are difficult to date but are certainly prehistoric – Neolithic, Copper Age and/or Early Bronze Age – and have frequently been found reused on later sites, as is the case at Outeiro do Circo.”

Outeiro do Circo is a Late Bronze Age fortified hilltop settlement spread across 17 hectares. Today, it appears as a long narrow hill in a relatively flat agricultural area. Archaeological investigations under directors Miguel Serra, Eduardo Porfirio and supervisor Sofia Eiras of Palimpsesto, Inc., are slowly revealing a major monumental site at this location. The cup-marked covinha, a find of its kind that remains a mystery for archaeologists, suggests an ancient significance associated with the object that has been the subject of competing theories. The curious find is not to distract from the importance of the context, however. 

“This huge area was enclosed by a complex defensive system: a double wall of stone, fire hardened clay and wood was augmented with bastions, ramps, platforms and an exterior retaining wall built on a disused ditch,” says Leonard. “By its size alone it is clear that Outeiro do Circo was an important location in the region. The site is one of the largest settlements of this time period in the Iberian Peninsula.”

Leonard and the archaeology team are currently investigating the interior area of the fortification. Toward that end, they have dug a number of trenches on the hilltop summit and inside its wall enclosure, a part of their goal to better understand what activities or functions were performed within it during the Late Bronze Age (1250 – 850 BC), and to determine how modern agriculture has disturbed the archaeological remains.

The most obvious feature, of course, has been the wall itself, an ancient construction that, according to the archaeologists, must have employed a great deal of labor — and an interesting technique. “Large amounts of clumped burnt clay were uncovered in the area of the enclosing wall,” says Leonard. “These clumps of burnt clay and the locations where they were found indicate to the archaeological team that one method used to strengthen the wall foundation was to set it on fire! To set a wall of this size alight, huge amounts of wood would have been heaved up to the top of the hill from the surrounding countryside. Imagine how a wall of fire on top of the highest point in the landscape would have appeared to a person in the Late Bronze Age! There is no doubt this would have demonstrated the importance and power of the wall-builders to anyone who saw the flames or told the story of what they had seen.”

Perhaps more telling about these ancient people, however, are the small finds uncovered and examined at the site. They could relate a story about the everyday lives of the long-gone inhabitants. “Fragments of pottery from the Chalcolithic to the Roman period have been found on the ground surface at Outeiro do Circo,” continues Leonard, “but by far the most common are those from the Late Bronze Age. In the 3m by 3m trench that I am helping to excavate some very interesting Late Bronze Age pottery fragments have been found that help to shed light on the activities that went on in the settlement. These fragments fill out the narrative of this site with evidence of how long the settlement was in use and details about the everyday life of those who lived there. 

Some fragments found in my excavation trench have small holes in them that were made before they were ‘fired’. These small holes could have been for hanging the vessels by cords for storage or during cooking. I also uncovered a small black pottery fragment that had been shaped into a disc from an already broken piece. From many other ancient examples found across Europe it is likely that this was a gaming piece, used to mark a player’s move in a game now long forgotten. A similar piece found at Outeiro do Circo in a previous season is the only known decorated example from Portugal. Another fascinating find was a small rough fragment with three indents on its surface. This is a piece of a broken strainer that could have been used to make cheese!”

According to what archaeologists have discovered to date, Outeiro do Circo was actually part of a larger Late Bronze Age culture or settlement region within a landscape that hosted other smaller settlements. 

Excavations at the Outeiro do Circo site are ongoing with likely much more work to be done before a clearer picture of the lives of these ancient people, who populated and built settlements in the area long before the Romans arrived, can come to light. Leonard’s time at the location was short-lived, however. She has moved on to Scotland, where she is participating in another excavation as part of a global year-long journey to work at twelve different archaeological sites in 12 separate countries. She calls her project Global Archaeology: A Year of Digs. Outeiro do Circo was the 8th stop on her global trek. 

Popular Archaeology will be following and reporting on Leonard’s worldwide experiences periodically throughout 2016 as she hops from one location to another during her global journey. To continue the work, however, Leonard will need financial support from donors. Readers interested in reading about and supporting her self-directed Global Archaeology crowdfunded project can learn more at gofundme.com/globalarchaeology.

Field Museum scientists unearth centuries-old crocodile stone

FIELD MUSEUM—In the 1960s, a team of excavators uncovered the ruins of the ancient city of Lambityeco (AD 500-850), in what is now Tlacolula de Matamoros, Oaxaca, Mexico. In a recent return to the site, the discovery of a carved stone crocodile by Field Museum archaeologists has provided a key to revising long-held ideas about the site.

During the early excavation, archaeologists unearthed seemingly conflicting evidence. On the one hand, they found a palace with iconic frescoes that indicate the close connections between Lambityeco and nearby Monte Albán, a much larger urban settlement in the region. However, not all of the pieces recovered during this study seemed to fit this narrative. Some of the artifacts showed marked differences with those from Monte Albán. Because of these differences, the archaeological team attributed Lambityeco to a later time period than Monte Albán, an interpretation that stood for decades. Nevertheless, more recent reanalysis of materials from Lambityeco has shown that the site was actually contemporaneous with Monte Albán, leading to new questions.

Over the last four years, new excavations led by Gary Feinman and Linda Nicholas of The Field Museum (in conjunction with Mexico’s National Institute of Anthropology and History) have expanded the investigated area at Lambityeco, and their discoveries have yielded a richer history than was originally thought. When the civic-ceremonial area of Lambityeco was first settled, the public buildings were clearly laid out in a manner closely reflective of that at Monte Albán. Yet, during the occupation, a major reorganization in the use of space occurred in the ceremonial core of Lambityeco. The architecture was remodeled so that it no longer reflected the construction patterns at the larger site. This shift likely reflected a distancing in the relationship between the two Valley of Oaxaca centers.

“During this time period, the relationship between Lambityeco and Monte Albán shifted,” said Field Museum MacArthur Curator of Anthropology Gary Feinman. “The people of Lambityeco began to remodel their buildings and reorient the use of space in order to differentiate themselves from Monte Albán.”

Evidence collected over the past four years has helped illustrate this change. One key feature that changed at Lambityeco was its ballcourt–an important structure for both ceremony and recreation in prehispanic Mesoamerica. In its original design, the ballcourt at Lambityeco, which was discovered by the Museum team in 2015, was laid out in a very similar pattern to the one in Monte Albán: both were constructed with the same orientation and were entered from the north side of the court. However, less than two centuries after the ballcourt was created in Lambityeco, the people sealed its north entrance and created a new stairway on its northeast corner–a major shift from the layout at Monte Albán. At this same time, the frescos in the palaces, excavated in the 1960s, were covered over, and never re-created again.

Another piece of evidence that helps illustrate this change at Lambityeco is a large stone carved on three sides with an image of a crocodile that was discovered during this recent field season. This is the largest carved stone found to date at Lambityeco. Although similar crocodile stones have been found at other sites in the Valley of Oaxaca, this was a unique discovery. Not only was it one of a few carvings of its kind to be discovered still in its prehispanic context, but the Field Museum team also found that the stone was moved from its original location during the long-ago occupation of Lambityeco.

“We believe that this crocodile stone was originally a part of a stairway leading up to a temple at the heart of the civic-ceremonial center of Lambityeco,” said Linda Nicholas, archaeologist at The Field Museum. “However, when the people reconstructed the core area of the site, the entrance to the temple was blocked and the stairway was dismantled.”

The stone was moved so that it leaned against the new façade of the building, where it continued to serve ritual significance, as evidenced by remains of charcoal and ceramics used to hold incense that were deposited right in front of the stone. The stone, when found in this location, was upside down with one of its carved sides completely hidden from view. These observations further indicate that the stone had been repositioned from its original location.

As new evidence continues to accumulate from Lambityeco, questions continue to arise. What caused this political shift between Lambityeco and Monte Albán? What is the full extent of architectural changes made within the city? Although anthropologists continue to work on answering these questions, it seems like one fact remains true. In its short-lived history, Lambityeco was a center of significant importance that still holds many clues to understanding the rich prehispanic history of the Valley of Oaxaca.

Evolution of human intelligence linked to blood flow to the brain

In a new research collaboration between Wits research entities – the Brain Function Research Group and Evolutionary Studies Institute – and the Cardiovascular Physiology team in the School of Biological Sciences at the University of Adelaide, previously held views on the evolutionary development of the human brain are being challenged.

The findings of their studies, published today in the Royal Society Open Science*, unseats previous theories that the progression of human intelligence is simply related to the increase in the size of the brain. The research team calculated how blood flowing to the brain of human ancestors changed over time, using the size of two holes at the base of the skull that allow arteries to pass to the brain. The findings, published in the Royal Society journal Open Science, thus allowed the researchers to track the increase in human intelligence across evolutionary time.

Their research found that while brain size has increased by about 350% over human evolution, blood flow to the brain increased by an amazing 600%. The increase in the supply of blood to the brain appears to be closely linked to the evolution of human intelligence where the human brain has evolved to become not only larger, but more energetically costly and blood thirsty than previously believed.

Wits Brain Function Research Group co-author Dr Edward Snelling says: “Ancient fossil skulls from Africa reveal holes where the arteries supplying the brain passed through. The size of these holes show how blood flow increased from 3 million year old Australopithecus to modern humans. The intensity of brain activity was, before now, believed to have been taken to the grave with our ancestors!”

“We believe this is possibly related to the brain’s need to satisfy increasingly energetic connections between nerve cells that allowed the evolution of complex thinking and learning,” said project leader Prof. Emeritus Roger Seymour of the University of Adelaide. “To allow our brain to be so intelligent, it must be constantly fed oxygen and nutrients from the blood. The more metabolically active the brain is, the more blood it requires, so the supply arteries are larger. The holes in fossil skulls are accurate gauges of arterial size.” Seymore suggests that the increasingly energetic connections between the nerve cells “allowed the evolution of complex thinking and learning.”

“Throughout evolution, the advance in our brain function appears to be related to the longer time it takes for us to grow out of childhood. It is also connected to family cooperation in hunting, defending territory and looking after our young,” Ms Bosiocic says.

“The emergence of these traits seems to nicely follow the increase in the brain’s need for blood and energy.”

Some people enhanced the environment, not degraded it, over past 13,000 years

UNIVERSITY OF WATERLOO—Human occupation is usually associated with deteriorated landscapes, but new research shows that 13,000 years of repeated occupation by British Columbia’s coastal First Nations has had the opposite effect, enhancing temperate rainforest productivity.

Andrew Trant, a professor in the Faculty of Environment at the University of Waterloo, led the study in partnership with the University of Victoria and the Hakai Institute. The research combined remote-sensed, ecological and archaeological data from coastal sites where First Nations’ have lived for millennia. It shows trees growing at former habitation sites are taller, wider and healthier than those in the surrounding forest. This finding is, in large part, due to shell middens and fire.

“It’s incredible that in a time when so much research is showing us the negative legacies people leave behind, here is the opposite story,” said Trant, a professor in Waterloo’s School of Environment, Resources and Sustainability. “These forests are thriving from the relationship with coastal First Nations. For more than 13,000 years –500 generations — people have been transforming this landscape. So this area that at first glance seems pristine and wild is actually highly modified and enhanced as a result of human behaviour.”

Fishing of intertidal shellfish intensified in the area over the past 6,000 years, resulting in the accumulation of deep shell middens, in some cases more than five metres deep and covering thousands of square metres of forest area. The long-term practice of harvesting shellfish and depositing remnants inland has contributed significant marine-derived nutrients to the soil as shells break down slowly, releasing calcium over time.

The study examined 15 former habitation sites in the Hakai Lúxvbálís Conservancy on Calvert and Hecate Islands using remote-sensed, ecological and archaeological methods to compare forest productivity with a focus on western red cedar.

The work found that this disposal and stockpiling of shells, as well as the people’s use of fire, altered the forest through increased soil pH and important nutrients, and also improved soil drainage.

This research is the first to find long-term use of intertidal resources enhancing forest productivity. Trant says it is likely similar findings will occur at archaeological sites along many global coastlines.

“These results alter the way we think about time and environmental impact,” he said. “Future research will involve studying more of these human-modified landscapes to understand the extent of these unexpected changes.”

How the most famous human ancestor died

UNIVERSITY OF TEXAS AT AUSTIN—Lucy, the most famous fossil of a human ancestor, probably died after falling from a tree, according to a study appearing in Nature led by researchers at The University of Texas at Austin.

Lucy, a 3.18-million-year-old specimen of Australopithecus afarensis—or “southern ape of Afar”—is among the oldest, most complete skeletons of any adult, erect-walking human ancestor. Since her discovery in the Afar region of Ethiopia in 1974 by Arizona State University anthropologist Donald Johanson and graduate student Tom Gray, Lucy—a terrestrial biped—has been at the center of a vigorous debate about whether this ancient species also spent time in the trees.

“It is ironic that the fossil at the center of a debate about the role of arborealism in human evolution likely died from injuries suffered from a fall out of a tree,” said lead author John Kappelman, a UT Austin anthropology and geological sciences professor.

Kappelman first studied Lucy during her U.S. museum tour in 2008, when the fossil detoured to the High-Resolution X-ray Computed Tomography Facility (UTCT) in the UT Jackson School of Geosciences—a machine designed to scan through materials as solid as a rock and at a higher resolution than medical CT. For 10 days, Kappelman and geological sciences professor Richard Ketcham carefully scanned all of her 40-percent-complete skeleton to create a digital archive of more than 35,000 CT slices.

“Lucy is precious. There’s only one Lucy, and you want to study her as much as possible,” Ketcham said. “CT is nondestructive. So you can see what is inside, the internal details and arrangement of the internal bones.”

Studying Lucy and her scans, Kappelman noticed something unusual: The end of the right humerus was fractured in a manner not normally seen in fossils, preserving a series of sharp, clean breaks with tiny bone fragments and slivers still in place.

“This compressive fracture results when the hand hits the ground during a fall, impacting the elements of the shoulder against one another to create a unique signature on the humerus,” said Kappelman, who consulted Dr. Stephen Pearce, an orthopedic surgeon at Austin Bone and Joint Clinic, using a modern human-scale, 3-D printed model of Lucy.

Pearce confirmed: The injury was consistent with a four-part proximal humerus fracture, caused by a fall from considerable height when the conscious victim stretched out an arm in an attempt to break the fall.

Kappelman observed similar but less severe fractures at the left shoulder and other compressive fractures throughout Lucy’s skeleton including a pilon fracture of the right ankle, a fractured left knee and pelvis, and even more subtle evidence such as a fractured first rib—”a hallmark of severe trauma”—all consistent with fractures caused by a fall. Without any evidence of healing, Kappelman concluded the breaks occurred perimortem, or near the time of death.

The question remained: How could Lucy have achieved the height necessary to produce such a high velocity fall and forceful impact? Kappelman argued that because of her small size—about 3 feet 6 inches and 60 pounds—Lucy probably foraged and sought nightly refuge in trees.

In comparing her with chimpanzees, Kappelman suggested Lucy probably fell from a height of more than 40 feet, hitting the ground at more than 35 miles per hour. Based on the pattern of breaks, Kappelman hypothesized that she landed feet-first before bracing herself with her arms when falling forward, and “death followed swiftly.”

“When the extent of Lucy’s multiple injuries first came into focus, her image popped into my mind’s eye, and I felt a jump of empathy across time and space,” Kappelman said. “Lucy was no longer simply a box of bones but in death became a real individual: a small, broken body lying helpless at the bottom of a tree.”

Kappelman conjectured that because Lucy was both terrestrial and arboreal, features that permitted her to move efficiently on the ground may have compromised her ability to climb trees, predisposing her species to more frequent falls. Using fracture patterns when present, future research may tell a more complete story of how ancient species lived and died.

In addition to the study, the Ethiopian National Museum provided access to a set of 3-D files of Lucy’s shoulder and knee for the public to download and print so that they can evaluate the hypothesis for themselves.

“This is the first time 3-D files have been released for any Ethiopian fossil hominin, and the Ethiopian officials are to be commended,” Kappelman said. “Lucy is leading the charge for the open sharing of digital data.”

Reconstructing the 6th century plague from a victim

MOLECULAR BIOLOGY AND EVOLUTION (OXFORD UNIVERSITY PRESS)—Before the infamous Black Death, the first great plague epidemic was the Justinian plague, which, over the course of two centuries, wiped out up to an estimated 50 million (15 percent) of the world’s population throughout the Byzantine Empire—and may have helped speed the decline of the eastern Roman Empire.

No one knows why it disappeared.

Recent molecular clues from ancient plague victims have suggested that plague may have been caused by the same bacterium, Yersinia pestis, which was responsible for the Black Death. But the geographic reach, mortality and impact of the Justinian pandemic are not fully known.

Both information from ancient hosts and bacteria could shed light on the role of plague, which has afflicted mankind for more than 5,000 years.

Now, scientists based in Germany, including Michal Feldman, Johannes Krause, Michaela Harbeck and colleagues have confirmed this by recovering the bacterial culprit from sixth century skeletons found in Altenerding, an ancient southern German burial site near Munich. The Altenerding genome dates back to the beginning of the plague.

They have generated the first high-coverage genome of the bacterial agent responsible for the Justinian plague. In addition to revealing new insights in the molecular evolution of Yersinia pestis since the Byzantine times, the new sequence shows features that could not detected due to the limitations in the coverage of a draft genome previously reported by Wagner*, including 30 newly identified mutations and structural rearrangements unique to the Justinianic strain., as well as correcting 19 false positive mutations.

“The fact that the archeological skeletons which gave these exciting insights were excavated over 50 years ago underscores the importance of maintaining well curated anthropological collections,” said author Michaela Harbeck. “We were very fortunate to find another plague victim with very good DNA preservation in a graveyard just a few kilometers from where the individual analyzed in Wagner et al. was found. It provided us with the great opportunity to reconstruct the first high quality genome in addition to the previously published draft genome.”

Three are located in genes critical to plague virulence: nrdE, fadJ and pcp genes. Their data also suggested that the strain was more genetically diverse than previously thought. How and why the pathogen reached Germany remains a mystery.

These new findings allow the authors to develop guidelines that could help improve the quality and authenticity of genomic data recovered from candidate ancient pathogens. And with plague classified as a re-emerging infectious disease in certain regions, an important historic, high-quality reference resource has been generated to offer insights into key the evolutionary changes, adaptation and human impact of plague.

“Our research confirms that the Justinianic plague reached far beyond the historically documented affected region and provides new insights into the evolutionary history of Yersinia pestis, illustrating the potential of ancient genomic reconstructions to broaden our understanding of pathogen evolution and of historical events,” said research colleague Michal Feldman. “Our reanalysis of previous datasets stresses the importance of following strict criteria to avoid errors in the reconstruction of ancient pathogen genomes.”

Ancient dental plaque sheds new light on the diet of Mesolithic foragers in the Balkans

UNIVERSITY OF CAMBRIDGE—The study of dental calculus from Late Mesolithic individuals from the site of Vlasac in the Danube Gorges of the central Balkans has provided direct evidence that Mesolithic foragers of this region consumed domestic cereals already by c. 6600 BC, i.e. almost half a millennium earlier than previously thought.

The team of researchers led by Emanuela Cristiani from The McDonald Institute for Archaeological Research, University of Cambridge used polarised microscopy to study micro-fossils trapped in the dental calculus (ancient calcified dental plaque) of 9 individuals dated to the Late Mesolithic (c. 6600-6450 BC) and the Mesolithic-Neolithic transition phase (c. 6200-5900 BC) from the site of Vlasac in the Danube Gorges. The remains were recovered from this site during excavations from 2006 to 2009 by Dušan Bori?, Cardiff University.

“The deposition of mineralised plaque ends with the death of the individual, therefore, dental calculus has sealed unique human biographic information about Mesolithic dietary preferences and lifestyle,” said Cristiani.

“What we happened to discover has a tremendous significance as it challenges the established view of the Neolithization in Europe,” she said.

“Microfossils trapped in dental calculus are a direct evidence that plant foods were an important source of energy within Mesolithic forager diet. More significantly, though, they reveal that domesticated plants were introduced to the Balkans independently from the rest of Neolithic novelties such as domesticated animals and artefacts, which accompanied the arrival of farming communities in the region”.

These results suggest that the hitherto held notion of the “Neolithic package” may have to be reconsidered. Archaeologists use the concept of “Neolithic package” to refer to the group of elements that appear in the Early Neolithic settlements of Southeast Europe: pottery, domesticates and cultigens, polished axes, ground stones and timber houses.

This region of the central Balkans has yielded unprecedented data for other areas with a known Mesolithic forager presence in Europe. Dental tartar samples were also taken from three Early Neolithic (c. 5900-5700 BC) female burials from the site of Lepenski Vir, located around 3 km upstream from Vlasac.

Although researchers agree that Mesolithic diet in the Danube Gorges was largely based on terrestrial, or riverine protein-rich resources, the team also found that starch granules preserved in the dental calculus from Vlasac were consistent with domestic species such as wheat (Triticum monococcum, Triticum dicoccum) and barley (Hordeum distichon), which were also the main crops found among Early Neolithic communities of southeast Europe.

Domestic species were consumed together with other wild species of the Aveneae tribe (oats), Fabaeae tribe (peas and beans) and grasses of the Paniceae tribe.

These preserved starch granules provide the first direct evidence that Neolithic domestic cereals had already reached inland foragers deep in the Balkan hinterland by c. 6600 BC. Their introduction in the Mesolithic societies was likely eased by social networks between local foragers and the first Neolithic communities.

Archaeological starch grains were interpreted using a large collection of microremains from modern plants native to the central Balkans and the Mediterranean region.

“Most of the starch granules that we identified in the Late Mesolithic calculus of the central Balkans are consistent with plants that became key staple domestic foods with the start of the Neolithic in this region” said Cristiani.

Anita Radini, University of York added, “In the central Balkans, foragers’ familiarity with domestic Cerealia grasses from c. 6500 BC, if not earlier, might have eased the later quick adoption of agricultural practices.”

The findings are published in the journal Proceedings of the National Academy of Sciences.

Isotope study determines fish were more prominent in early Alaskans’ diets

UNIVERSITY OF ALASKA FAIRBANKS—Ice age inhabitants of Interior Alaska relied more heavily on salmon and freshwater fish in their diets than previously thought, according to a newly published study.

A team of researchers from the University of Alaska Fairbanks made the discovery after taking samples from 17 prehistoric hearths along the Tanana River, then analyzed stable isotopes and lipid residues to identify fish remains at multiple locations. The results offer a more complex picture of Alaska’s ice age residents, who were previously thought to have a diet dominated by terrestrial mammals such as mammoths, bison and elk.

The project also found the earliest evidence of human use of anadromous salmon in the Americas, dating back at least 11,800 years.

The results of the study were published today in the Proceedings of the National Academy of Sciences.

DNA analysis of chum salmon bones from the same site on the Tanana River had previously confirmed that fish were part of the local indigenous diet as far back as 11,500 years ago. But fragile fish bones rarely survive for scientists to analyze, so the team used sophisticated geochemistry analyses to estimate the amount of salmon, freshwater and terrestrial resources ancient people ate.

A team led by UAF postdoctoral researcher Kyungcheol Choy analyzed stable isotopes and lipid residues, searching for signatures specific to anadromous fish. The effort demonstrated that dietary practices of hunter-gatherers could be recorded at sites where animal remains hadn’t been preserved.

“It’s quite new in the archaeology field,” Choy said. “There’s a lot in these mixtures that’s hard to detect in other ways.”

Ben Potter, a professor of anthropology at UAF and co-author of the study, said the findings suggest a more systematic use of salmon than DNA testing alone could confirm.

“This is a different kind of strategy,” Potter said. “It fleshes out our understanding of these people in a way that we didn’t have before.”

The study required cooperation between UAF’s Department of Anthropology and the Institute of Northern Engineering’s Alaska Stable Isotope Facility to locate and interpret the presence of salmon remains at the sites. Potter said the process could be a template for how a diverse team of researchers can work together to overcome a scientific obstacle.

“It’s an awesome look at how we can merge disciplines to answer a question,” he said.

One of the most significant Etruscan discoveries in decades names female goddess Uni

SOUTHERN METHODIST UNIVERSITY—Archaeologists translating a very rare inscription on an ancient Etruscan temple stone have discovered the name Uni—an important female goddess.

The discovery indicates that Uni—a divinity of fertility and possibly a mother goddess at this particular place—may have been the titular deity worshipped at the sanctuary of Poggio Colla, a key settlement in Italy for the ancient Etruscan civilization.

The mention is part of a sacred text that is possibly the longest such Etruscan inscription ever discovered on stone, said archaeologist Gregory Warden, professor emeritus at Southern Methodist University, Dallas, main sponsor of the archaeological dig.

Scientists on the research discovered the ancient stone embedded as part of a temple wall at Poggio Colla, a dig where many other Etruscan objects have been found, including a ceramic fragment with the earliest birth scene in European art. That object reinforces the interpretation of a fertility cult at Poggio Colla, Warden said.

Now Etruscan language experts are studying the 500-pound slab—called a stele (STEE-lee)—to translate the text. It’s very rare to identify the god or goddess worshipped at an Etruscan sanctuary.

“The location of its discovery—a place where prestigious offerings were made—and the possible presence in the inscription of the name of Uni, as well as the care of the drafting of the text, which brings to mind the work of a stone carver who faithfully followed a model transmitted by a careful and educated scribe, suggest that the document had a dedicatory character,” said Adriano Maggiani, formerly Professor at the University of Venice and one of the scholars working to decipher the inscription.

“It is also possible that it expresses the laws of the sanctuary—a series of prescriptions related to ceremonies that would have taken place there, perhaps in connection with an altar or some other sacred space,” said Warden, co-director and principal investigator of the Mugello Valley Archaeological Project.

Warden said it will be easier to speak with more certainty once the archaeologists are able to completely reconstruct the text, which consists of as many as 120 characters or more. While archaeologists understand how Etruscan grammar works, and know some of its words and alphabet, they expect to discover new words never seen before, particularly since this discovery veers from others in that it’s not a funerary text.

The Mugello Valley archaeologists are announcing discovery of the goddess Uni at an exhibit in Florence on Aug. 27, “Scrittura e culto a Poggio Colla, un santuario etrusco nel Mugello,” and in a forthcoming article in the scholarly journal Etruscan Studies.

Text may specify the religious ritual for temple ceremonies dedicated to the goddess

It’s possible the text contains the dedication of the sanctuary, or some part of it, such as the temple proper, so the expectation is that it will reveal the early beliefs of a lost culture fundamental to western traditions.

The sandstone slab, which dates to the 6th century BCE and is nearly four feet tall by more than two feet wide, was discovered in the final stages of two decades of digging at Mugello Valley, which is northeast of Florence in north central Italy.

Etruscans once ruled Rome, influencing that civilization in everything from religion and government to art and architecture. A highly cultured people, Etruscans were also very religious and their belief system permeated all aspects of their culture and life.

Inscription may reveal data to understand concepts and rituals, writing and language

Permanent Etruscan inscriptions are rare, as Etruscans typically used linen cloth books or wax tablets. The texts that have been preserved are quite short and are from graves, thus funerary in nature.

“We can at this point affirm that this discovery is one of the most important Etruscan discoveries of the last few decades,” Warden said. “It’s a discovery that will provide not only valuable information about the nature of sacred practices at Poggio Colla, but also fundamental data for understanding the concepts and rituals of the Etruscans, as well as their writing and perhaps their language.”

Besides being possibly the longest Etruscan inscription on stone, it is also one of the three longest sacred texts to date.

One section of the text refers to “tina?,” a reference to Tina, the name of the supreme deity of the Etruscans. Tina was equivalent to ancient Greece’s Zeus or Rome’s Jupiter.

Once an imposing and monumental symbol of authority

The slab was discovered embedded in the foundations of a monumental temple where it had been buried for more than 2,500 years. At one time it would have been displayed as an imposing and monumental symbol of authority, said Warden, president and professor of archaeology at Franklin University Switzerland.

The text is being studied by two noted experts on the Etruscan language, including Maggiani, who is an epigrapher, and Rex Wallace, Professor of Classics at the University of Massachusetts Amherst, who is a comparative linguist.

A hologram of the stele will be shown at the Florence exhibit, as conservation of the stele is ongoing at the conservation laboratories of the Archaeological Superintendency in Florence. Digital documentation is being done by experts from the architecture department of the University of Florence. The sandstone is heavily abraded and chipped, so cleaning should allow scholars to read the inscription.

Other objects unearthed in the past 20 years have shed light on Etruscan worship, beliefs, gifts to divinities, and discoveries related to the daily lives of elites and non-elites, including workshops, kilns, pottery and homes. The material helps document ritual activity from the 7th century to the 2nd century BCE.

Besides SMU, other collaborating institutions at Mugello Valley Archaeological Project include Franklin and Marshall College, the University of Pennsylvania Museum of Archaeology, the Center for the Study of Ancient Italy at The University of Texas at Austin, The Open University (UK), and Franklin University Switzerland.

Water management and the demise of the Maya civilization

VIENNA UNIVERSITY OF TECHNOLOGY—Something really drastic must have happened to the Ancient Maya at the end of the Classic Period in the 9th century. Within a short period of time, this advanced civilisation in Central America went from flourishing to collapsing—the population dwindling rapidly and monumental stone structures, like the ones built at Yucatán, were no longer being constructed. The reason for this demise remains the subject of debate even today. Model calculations by TU Wien may have found the explanation: the irrigation technology that served the Mayans well during periods of drought may have actually made their society more vulnerable to major catastrophes.

The lessons learned may also help us to draw important conclusions for our own future. We need to be careful with our natural resources—if technical measures simply deal with the shortage of resources on a superficial level and we do not adjust our own behavior, society is left vulnerable.

Socio-hydrology

“Water influences society and society influences water,” says Linda Kuil, one of Prof. Günter Blöschl’s PhD students of the Vienna Doctoral Programme on Water Resource Systems, funded by the Austrian Science Fund, at TU Wien. “The water supply determines how much food is available, so in turn affects the growth of the population. Conversely, population increases may interfere with the natural water cycle through the construction of reservoirs, for example.”

Since water and society have such a direct influence on each other, it will not suffice to describe them by separate models. This is why researchers at TU Wien explore the interactions between sociology and hydrology and represent them by coupled mathematical models. The emerging field of socio-hydrology establishes mathematical interrelationships, e.g., between food availability and birth rate, or between recent water shortages that are still fresh in our memories and society’s plans for building water reservoirs. These kinds of interrelationships, combined with a large amount of historical and current data, ultimately yield a complex system that produces different scenarios of human-nature interactions.

The water reservoir: a blessing and a curse

“It’s well-known that the Mayans built water reservoirs in preparation for dry spells,” Linda Kuil says. “With our model, we can now analyse the effects of the Mayans’ water engineering on their society. It is also possible to simulate scenarios with and without water reservoirs and compare the consequences of such decisions.”

As it turns out, water reservoirs can actually provide substantial relief during short periods of drought. In the simulations without reservoirs the Mayan population declines after a drought, whereas it continues to grow if reservoirs provide extra water. However, the reservoirs may also make the population more vulnerable during prolonged dry spells. The water management behaviour may remain the same, and the water demand per person does not decrease, but the population continues to grow. This may then prove fatal if another drought occurs resulting in a decline in population that is more dramatic than without reservoirs.

Sustainable use of resources

We will probably never know all the reasons for the decline of the Mayans. After all, wars or epidemics may have played their part too. The socio-hydrological model developed by the Günter Blöschl-led team of researchers at TU Wien does, however, tell us that droughts and water issues are one possible explanation for their demise and shows us just how vulnerable an engineered society can be. “When it comes to scarce resources, the simplest solutions might turn out to be superficial and not always the best ones,” Linda Kuil believes. “You have to change people’s behaviour, reassess society’s dependency on this resource and reduce consumption—otherwise society may in fact be more vulnerable to catastrophes rather than safer, despite clever technical solutions.”

Chimpanzees choose cooperation over competition

EMORY HEALTH SCIENCES—When given a choice between cooperating or competing, chimpanzees choose to cooperate five times more frequently Yerkes National Primate Research Center researchers have found. This, the researchers say, challenges the perceptions humans are unique in our ability to cooperate and chimpanzees are overly competitive, and suggests the roots of human cooperation are shared with other primates. The study results are reported in this week’s early online edition of the Proceedings of the National Academy of Sciences.

To determine if chimpanzees possess the same ability humans have to overcome competition, the researchers set up a cooperative task that closely mimicked chimpanzee natural conditions, for example, providing the 11 great apes that participated in this study with an open choice to select cooperation partners and giving them plenty of ways to compete. Working beside the chimpanzees’ grassy outdoor enclosure at the Yerkes Research Center Field Station, the researchers gave the great apes thousands of opportunities to pull cooperatively at an apparatus filled with rewards. In half of the test sessions, two chimpanzees needed to participate to succeed, and in the other half, three chimpanzees were needed.

While the set up provided ample opportunities for competition, aggression and freeloading, the chimpanzees overwhelmingly performed cooperative acts – 3,565 times across 94 hour-long test sessions.

The chimpanzees used a variety of enforcement strategies to overcome competition, displacement and freeloading, which the researchers measured by attempted thefts of rewards. These strategies included the chimpanzees directly protesting against others, refusing to work in the presence of a freeloader, which supports avoidance as an important component in managing competitive tendencies, and more dominant chimpanzees intervening to help others against freeloaders. Such third-party punishment occurred 14 times, primarily in response to aggression between the freeloader and the chimpanzee that was cooperatively working with others for the rewards.

“Previous statements in the literature describe human cooperation as a ‘huge anomaly’ and chimpanzees as preferring competition over collaboration,” says Malini Suchak, PhD, lead author of the study. “Studies have also suggested researchers have to ‘engineer cooperation’ during experiments rather than acknowledging chimpanzees are naturally cooperative. When we considered chimpanzees’ natural behaviors, we thought surely they must be able to manage competition on their own, so we gave them the freedom to employ their own enforcement strategies. And it turns out, they are really quite good at preventing competition and favoring cooperation. In fact, given the ratio of conflict to cooperation is quite similar in humans and chimpanzees, our study shows striking similarities across species and gives another insight into human evolution,” she continues. Suchak was a graduate student at the Yerkes Research Center at the time of the study and is now an Assistant Professor of Animal Behavior, Ecology and Conservation at Canisius College in Buffalo, NY.

Frans de Waal, PhD, director of the Living Links Center at the Yerkes Research Center, a C. H. Candler Professor of Psychology at Emory University and one of the study authors, adds, “It has become a popular claim in the literature that human cooperation is unique. This is especially curious because the best ideas we have about the evolution of cooperation come straight from animal studies. The natural world is full of cooperation, from ants to killer whales. Our study is the first to show that our closest relatives know very well how to discourage competition and freeloading. Cooperation wins!”

Hidden Ancient Mexican Manuscript Discovered

ELSEVIER—OXFORD, 16 August 2016 – Researchers from the University of Oxford’s Bodleian Libraries and from universities in the Netherlands have used high-tech imaging to uncover the details of a rare Mexican codex dating from before the colonization of the Americas.* The newly revealed codex, or book, has been hidden from view for almost 500 years, concealed beneath a layer of plaster and chalk on the back of a later manuscript known as the Codex Selden, which is housed at the Bodleian Libraries. Scientists have used hyperspectral imaging to reveal pictographic scenes from this remarkable document and have published their findings in the Journal of Archaeological Science: Reports.

Ancient Mexican codices are some of the most important artifacts of early Mexican culture and they are particularly rare. Codex Selden, also known as Codex Añute, dates from around 1560 and is one of fewer than 20 known Mexican codices to have survived from pre-colonial and early colonial Mexico. Of those, it is one of only five surviving manuscripts from the Mixtec area, now the Oaxaca region of Mexico. These codices use a complex system of pictures, symbols and bright colors to narrate centuries of conquering dynasties and genealogies as well as wars and the history of ancient cities. In essence these codices provide the best insight into the history and culture of early Mexico.

Since the 1950s, scholars have suspected that Codex Selden is a palimpsest: an older document that has been covered up and reused to make the manuscript that is currently visible. Codex Selden consists of a five-meter-long strip composed of deer hide that has been covered with gesso, a white plaster made from gypsum and chalk, and folded in a concertina format into a 20-page document. The manuscript underwent a series of invasive tests in the 1950s when one page on the back was scraped, uncovering a vague image that hinted at the possibility that an earlier Mexican codex lay hidden beneath.

Until now, no other technique has been able to unveil the concealed narrative in a non-invasive way. The organic paints that were partly used to create the vibrant images on early Mexican codices do not absorb x-rays, which rules out x-ray analysis that is commonly used to study later works of art.

‘After four or five years of trying different techniques, we’ve been able to reveal an abundance of images without damaging this extremely vulnerable item. We can confirm that Codex Selden is indeed a palimpsest,’ said Ludo Snijders from Leiden University, who conducted the research with David Howell from the Bodleian Libraries and Tim Zaman from the University of Delft. This is the first time an early Mexican codex has been proven to be a palimpsest.

‘What’s interesting is that the text we’ve found doesn’t match that of other early Mixtec manuscripts. The genealogy we see appears to be unique, which means it may prove invaluable for the interpretation of archaeological remains from southern Mexico,’ Snjiders said.

Some pages feature more than 20 characters sitting or standing in the same direction. Similar scenes have been found on other Mixtec manuscripts, representing a King and his council. But the analysis of this particular text shows that the characters are both male and female, raising interesting questions about what the scene represents.

The imaging has also revealed a prominent individual who appears repeatedly on the document and is represented by a large glyph consisting of a twisted cord and a flint knife. The name seems to resemble a character found in other Mexican codices: the Codex Bodley (in the Bodleian’s collection) and Codex Zouche-Nuttall (in the British Museum).That character is an important ancestor of two lineages connected to the important archaeological sites of Zaachila and Teozacualco in Mexico. However, further analysis is needed to confirm that it is the same individual.

The researchers analysed seven pages of the codex for this study and revealed other images including people walking with sticks and spears, women with red hair or headdresses and place signs containing the glyphs for rivers. They are continuing to analyse the remainder of the document with the aim of reconstructing the entire hidden imagery, allowing the text to be interpreted more fully.

‘Hyperspectral imaging has shown great promise in helping us to begin to reconstruct the story of the hidden codex and ultimately to recover new information about Mixtec history and archaeology,’ said David Howell, Head of Heritage Science at the Bodleian Libraries. ‘This is very much a new technique, and we’ve learned valuable lessons about how to use hyperspectral imaging in the future both for this very fragile manuscript and for countless others like it.’

Working with the Humanities Division in the University of Oxford, the Libraries acquired the hyperspectral scanner in 2014 with the support of the University’s Fell Fund. Once a technique used by astrophysicists to study the color of stars, hyperspectral imaging is now used by Bodleian researchers to reveal hidden text and images and identify unknown substances and pigments with a high degree of accuracy. Researchers have recently used the scanner to clarify the text of the famous Bakhshali manuscript from India, which includes the first use of zero, to analyze the medieval Gough Map, the earliest road map of Great Britain and to reveal a hidden devil in a centuries-old Armenian gospel-book.

Tool or weapon?

INDIANA UNIVERSITY, BLOOMINGTON, Ind.—A team of psychologists, kinesiologists and archaeologists at Indiana University and elsewhere are throwing new light on a longstanding archaeological mystery: the purpose of a large number of spherical stone artifacts found at a major archaeological site in South Africa.

IU Bloomington professor Geoffrey Bingham and colleagues in the United Kingdom and United States contend that the stones—previously thought by some to be used as tools—served instead as weapons for defense and hunting.

The research, which combines knowledge about how modern humans perceive an object’s “throwing affordance” with mathematical analysis and evaluation of these stones as projectiles for throwing, appears in the journal Scientific Reports.

“Our study suggests that the throwing of stones played a key role in the evolution of hunting,” said Bingham, a professor in the IU Bloomington College of Arts and Sciences’ Department of Psychological and Brain Sciences and an author on the study. “We don’t think that throwing is the sole, or even primary, function of these spheroids, but these results show that this function is an option that warrants reconsidering as a potential use for this long-lived, multipurpose tool.”

The use of these stones, which date from between 1.8 million and 70,000 years ago, has puzzled archaeologists since they were unearthed at the Cave of Hearths in South Africa’s Makapan Valley nearly 30 years ago.

The study’s lead author, Andrew Wilson of Beckett Leeds University in England, and co-author, Qin Zhu of the University of Wyoming, were both Ph.D. students in Bingham’s lab at IU. The other researchers are archaeologists Lawrence Barham and Ian Stanistreet, both of the University of Liverpool in England. Stanistreet is also affiliated with the Stone Age Institute at IU.

The team’s conclusions are based upon a theoretical framework and computational tools developed in the Perception/Action Lab at IU, directed by Bingham, who investigates human coordinated action and perceptual capabilities. This includes judging an object’s throwing affordance, which is the selection of the best object in terms of size, weight and shape for throwing at maximum distance, speed and damage.

Using these methods, the researchers used computational models to analyze 55 ball-shaped stone objects from the South African site, finding that 81 percent of the stones were the optimal size, weight and shape for hitting such a target at a 25-meter distance. The stones are about the size of tennis balls but much heavier.

The team also simulated the projectile motions the spheroids would undergo if thrown by an expert, as well as estimated the probability of these projectiles causing damage to a medium-sized prey such as an impala.

Research on biomechanics and perception, particularly vision, shows that the human shoulder joint and perceptual abilities are uniquely specialized for throwing objects aimed at a particular target at a distance of 20 to 30 meters, Bingham said. The stones, which predate thrown spears, likely served as projectile weapons for hunting and defense since they were found to perform best as hunting weapons when thrown overhand, he added.

“Humans are the only animals—the only primates even—with that talent,” Bingham said. “We can throw something to hit something else—like a quarterback throwing to the running back all the way down the field. That’s how in large measure we survived the ice ages. The available food was largely on hoof, or it was ‘mega-fauna,’ such as a mammoth. You don’t want to get close to them.”

Previous research by archaeologists suggested that spherical stones were used as percussive tools for shaping or grinding other materials. Most of the objects analysed in this study had weights that produce optimal levels of damage from throwing, however, rather than simply being as heavy as possible.

“Imagine a human, searching for an object to throw so as to cause the most damage possible to potential prey or a competitor,” Wilson said. “This is a perceptual task: the person needs to perceive throwing-relevant properties of objects and be able to discriminate between objects that vary in those properties.”

Bingham, along with former students and other colleagues, have been studying the mechanics and evolutionary role of throwing—a complex human action—for several decades at IU. Over time, they developed both theories on this capability, as well as virtual simulations to measure the mechanics of the task.

“The ability to throw great distances was not a small thing,” Bingham said. “It was how we got lunch.”

Tree-rings reveal secret clocks that could reset key dates across the ancient world

UNIVERSITY OF OXFORD—Oxford University researchers say that trees which grew during intense radiation bursts in the past have ‘time-markers’ in their tree-rings that could help archaeologists date events from thousands of years ago. In a new paper*, the authors explain how harvesting such data could revolutionize the study of ancient civilizations such as the Egyptian and Mayan worlds. Until now scholars have had only vague evidence for dating when events happened during the earliest periods of civilization, with estimates accurate within a differential of hundreds of years. However, the unusually high levels of the radioactive isotope carbon-14 found in tree-rings laid down during radiation bursts could help reliably pinpoint dates. The distinct spikes act as time-markers like secret clocks contained in timber, papyri, baskets made from living plants or other organic materials, according to the paper published in the Royal Society Journal Proceedings A.

Scholars believe that intense solar storms caused major bursts of radiation, striking the Earth in 775 and 994 CE, which resulted in distinct spikes in the concentration of radiocarbon in trees growing at that time. The events are precisely datable because the tree-rings belong to archives in which the growth year of each tree-ring is exactly known. In the new research, the authors outline how they could detect similar spikes elsewhere within the thousands of years of available tree-ring material from across the world. They say even a handful of these time-markers could allow them to piece together a reliable dating framework for important civilizations. The crucial point is that the time-markers will also be present in every living plant or tree that grew at the time of a radiation surge, including in the timber used in ancient buildings or other artifacts fashioned from the plants. The paper suggests that the existing tree-ring data are likely to reveal other radiocarbon surges in particular years. The problem, however, is that the tree-ring data is only available in blocks of decades rather than year by year. The paper proposes a cutting-edge mathematical method to filter out particular years within such a block when ‘change points’ in radiocarbon levels occurred. It also adds that it is currently unclear how regularly the Earth has been hit by such intense bursts of radiation, and what the precise magnitude of the events might have been, so finding new spikes will also help us understand past solar activity.

Currently, archaeologists have to rely on relatively sparse evidence for dating the history of Western civilization before 763 BCE, with Chinese history also only widely agreed from 841 BCE. For example, they depend on ancient records of rare astronomical phenomena, such as the solar eclipse during the ninth year of Ashur Dan III of Assyria, to determine the age of historical events. In the absence of such records, standard radiocarbon measurements provide the best estimates, but these are still often only accurate to within 200 to 300 calendar years. If the radiocarbon spikes in the tree-ring data were also found in archaeological items attributable to specific historical periods, the information could be used to anchor exactly when events occurred, say the researchers.

Lead author Dr Michael Dee, from the School of Archaeology at the University of Oxford, said: “Variations in atmospheric radiocarbon concentration are largely the result of carbon dioxide emissions from activity from volcanoes and the ocean, but they are also influenced by changes in solar activity. The spikes in 775 and 994 CE were almost vertical and of comparable magnitude all around the Earth. Such markers can be easily identified in known-age tree-rings and are fixed in time. In the past, we have had floating estimates of when things may have happened, but these secret clocks could reset chronologies concerning important world civilizations with the potential to date events that happened many thousands of years ago to the exact year.”

Astronomy shown to be set in standing stone

UNIVERSITY OF ADELAIDE—University of Adelaide research has for the first time statistically proven that the earliest standing stone monuments of Britain, the great circles, were constructed specifically in line with the movements of the Sun and Moon, 5000 years ago.

The research, published in the Journal of Archaeological Science: Reports, details the use of innovative 2D and 3D technology to construct quantitative tests of the patterns of alignment of the standing stones.

“Nobody before this has ever statistically determined that a single stone circle was constructed with astronomical phenomena in mind – it was all supposition,” says project leader and University of Adelaide Visiting Research Fellow Dr Gail Higginbottom, who is also a Visiting Research Fellow at the Australian National University.

Examining the oldest great stone circles built in Scotland (Callanish, on the Isle of Lewis, and Stenness, Isle of Orkney—both predating Stonehenge’s standing stones by about 500 years), the researchers found a great concentration of alignments towards the Sun and Moon at different times of their cycles. And 2000 years later in Scotland, much simpler monuments were still being built that had at least one of the same astronomical alignments found at the great circles.

The stones, however, are not just connected with the Sun and the Moon. The researchers discovered a complex relationship between the alignment of the stones, the surrounding landscape and horizon, and the movements of the Sun and the Moon across that landscape.

“This research is finally proof that the ancient Britons connected the Earth to the sky with their earliest standing stones, and that this practice continued in the same way for 2000 years,” says Dr Higginbottom.

Examining sites in detail, it was found that about half the sites were surrounded by one landscape pattern and the other half by the complete reverse.

“These chosen surroundings would have influenced the way the Sun and Moon were seen, particularly in the timing of their rising and setting at special times, like when the Moon appears at its most northerly position on the horizon, which only happens every 18.6 years,” Dr Higginbottom says.

“For example, at 50% of the sites, the northern horizon is relatively higher and closer than the southern and the summer solstice Sun rises out of the highest peak in the north. At the other 50% of sites, the southern horizon is higher and closer than the northern, with the winter solstice Sun rising out of these highest horizons.

“These people chose to erect these great stones very precisely within the landscape and in relation to the astronomy they knew. They invested a tremendous amount of effort and work to do so. It tells us about their strong connection with their environment, and how important it must have been to them, for their culture and for their culture’s survival.”

The great stone circle, Stenness on the Isle of Orkney, is situated in a ‘reverse’ landscape. The project examined the alignments running from the center of circle through the stones on the circle’s perimeter and the stone holes where stones formally stood (as revealed by excavation). This told us that the stone furthest to the right is oriented upon the last glimmer of a southern Moon occurring only every 18.6 years; the second stone is aligned towards the winter solstice sunset and the stone furthest to our left is aligned to the Moon as it sets into its most northern position every 18.6 years. These are astronomical events that could be seen 5000 years ago. Credit: Douglas Scott.

Great Archaeological Discoveries of All Time

Claire Collins has worked with Caherconnell Stone Fort for over five years. Caherconnell Stone Fort is a medieval, extraordinarily well-preserved stone ringfort in The Burren of County Clare, Ireland. At Caherconnell, there is an archaeology and a geology field school where one can delve into the Irish prehistoric world. Caherconnell is also home to Ireland’s leading sheepdog demonstrations, which attract thousands of tourists each year. 

For centuries archaeologists, excavators and historians have been discovering ancient devices, uncovering treasured artifacts and revealing cities that had long been lost. These discoveries, no matter how small they may seem, are vital for our understanding of our ancestors. Discoveries such as the Rosetta stone, the Dead Sea Scrolls and Sacsayhuaman allow us to get a glimpse into the lives of those that have inhabited the earth before us. Some of the most momentous discoveries have resulted in a deeper understanding of ancient customs and teachings. For details on some of the most fascinating archaeological discoveries of all time, let’s take a look at the infographic below by Caherconnell Stone Fort!

An ancient Mayan Copernicus

UNIVERSITY OF CALIFORNIA – SANTA BARBARA—For more than 120 years the Venus Table of the Dresden Codex—an ancient Mayan book containing astronomical data—has been of great interest to scholars around the world. The accuracy of its observations, especially the calculation of a kind of ‘leap year’ in the Mayan Calendar, was deemed an impressive curiosity used primarily for astrology.

But UC Santa Barbara’s Gerardo Aldana, a professor of anthropology and of Chicana and Chicano studies, believes the Venus Table has been misunderstood and vastly underappreciated. In a new journal article, Aldana makes the case that the Venus Table represents a remarkable innovation in mathematics and astronomy—and a distinctly Mayan accomplishment. “That’s why I’m calling it ‘discovering discovery,’ ” he explained, “because it’s not just their discovery, it’s all the blinders that we have, that we’ve constructed and put in place that prevent us from seeing that this was their own actual scientific discovery made by Mayan people at a Mayan city.”

Multitasking science

Aldana’s paper, “Discovering Discovery: Chich’en Itza, the Dresden Codex Venus Table and 10th Century Mayan Astronomical Innovation,” in the Journal of Astronomy in Culture, blends the study of Mayan hieroglyphics (epigraphy), archaeology and astronomy to present a new interpretation of the Venus Table, which tracks the observable phases of the second planet from the Sun. Using this multidisciplinary approach, he said, a new reading of the table demonstrates that the mathematical correction of their “Venus calendar”—a sophisticated innovation—was likely developed at the city of Chich’en Itza during the Terminal Classic period (AD 800-1000). What’s more, the calculations may have been done under the patronage of K’ak’ U Pakal K’awiil, one of the city’s most prominent historical figures.

“This is the part that I find to be most rewarding, that when we get in here, we’re looking at the work of an individual Mayan, and we could call him or her a scientist, an astronomer,” Aldana said. “This person, who’s witnessing events at this one city during this very specific period of time, created, through their own creativity, this mathematical innovation.”

The Venus Table

Scholars have long known that the Preface to the Venus Table, Page 24 of the Dresden Codex, contained what Aldana called a “mathematical subtlety” in its hieroglyphic text. They even knew what it was for: to serve as a correction for Venus’s irregular cycle, which is 583.92 days. “So that means if you do anything on a calendar that’s based on days as a basic unit, there is going to be an error that accrues,” Aldana explained. It’s the same principle used for Leap Years in the Gregorian calendar. Scholars figured out the math for the Venus Table’s leap in the 1930s, Aldana said, “but the question is, what does it mean? Did they discover it way back in the 1st century BC? Did they discover it in the 16th? When did they discover it and what did it mean to them? And that’s where I come in.”

Unraveling the mystery demanded Aldana employ a unique set of skills. The first involved epigraphy, and it led to an important development: In poring over the Table’s hieroglyphics, he came to realize that a key verb, k’al, had a different meaning than traditionally interpreted. Used throughout the Table, k’al means “to enclose” and, in Aldana’s reading, had a historical and cosmological purpose.

Rethinking assumptions

That breakthrough led him to question the assumptions of what the Mayan scribe who authored the text was doing in the Table. Archaeologists and other scholars could see its observations of Venus were accurate, but insisted it was based in numerology. “They [the Maya] knew it was wrong, but the numerology was more important. And that’s what scholars have been saying for the last 70 years,” Aldana said.

“So what I’m saying is, let’s step back and make a different assumption,” he continued. “Let’s assume that they had historical records and they were keeping historical records of astronomical events and they were consulting them in the future—exactly what the Greeks did and the Egyptians and everybody else. That’s what they did. They kept these over a long period of time and then they found patterns within them. The history of Western astronomy is based entirely on this premise.”

To test his new assumption, Aldana turned to another Mayan archaeological site, Copán in Honduras. The former city-state has its own record of Venus, which matched as a historical record the observations in the Dresden Codex. “Now we’re just saying, let’s take these as historical records rather than numerology,” he said. “And when you do that, when you see it as historical record, it changes the interpretation.”

Putting the pieces together

The final piece of the puzzle was what Aldana, whose undergraduate degree was in mechanical engineering, calls “the machinery,” or how the pieces fit together. Scholars know the Mayans had accurate observations of Venus, and Aldana could see that they were historical, not numerological. The question was, Why? One hint lay more than 500 years in the future: Nicolaus Copernicus.

The great Polish astronomer stumbled into the heliocentric universe while trying to figure out the predictions for future dates of Easter, a challenging feat that requires good mathematical models. That’s what Aldana saw in the Venus Table. “They’re using Venus not just to strictly chart when it was going to appear, but they were using it for their ritual cycles,” he explained. “They had ritual activities when the whole city would come together and they would do certain events based on the observation of Venus. And that has to have a degree of accuracy, but it doesn’t have to have overwhelming accuracy. When you change that perspective of, ‘What are you putting these cycles together for?’ that’s the third component.”

Putting those pieces together, Aldana found there was a unique period of time during the occupation of Chichen’Itza when an ancient astronomer in the temple that was used to observe Venus would have seen the progressions of the planet and discovered it was a viable way to correct the calendar and to set their ritual events.

“If you say it’s just numerology that this date corresponds to; it’s not based on anything you can see. And if you say, ‘We’re just going to manipulate them [the corrections written] until they give us the most accurate trajectory,’ you’re not confining that whole thing in any historical time,” he said. “If, on the other hand, you say, ‘This is based on a historical record,’ that’s going to nail down the range of possibilities. And if you say that they were correcting it for a certain kind of purpose, then all of a sudden you have a very small window of when this discovery could have occurred.”

A Mayan achievement

By reinterpreting the work, Aldana said it puts the Venus Table into cultural context. It was an achievement of Mayan science, and not a numerological oddity. We might never know exactly who made that discovery, he noted, but recasting it as a historical work of science returns it to the Mayans.

“I don’t have a name for this person, but I have a name for the person who is probably one of the authority figures at the time,” Aldana said. “It’s the kind of thing where you know who the pope was, but you don’t know Copernicus’s name. You know the pope was giving him this charge, but the person who did it? You don’t know his or her name.”
