An iconic Native American stone tool technology discovered in Arabia

MAX PLANCK INSTITUTE FOR THE SCIENCE OF HUMAN HISTORY—A new study led by archaeologists from the CNRS, the Inrap, the Ohio State University and the Max Planck Institute for the Science of Human History, reports on fluted points from the archaeological sites of Manayzah in Yemen and Ad-Dahariz in Oman. Fluted stone tools are a distinctive, technologically advanced form of projectile points, including spearheads and arrowheads. Fluting is a specific technique that involves the extraction of an elongated flake along the length of a projectile point, leaving a distinctive groove or depression at the base of the spearhead or arrowhead.

Fluting is a distinct technological tradition invented by early human cultures that spread across the Americas. Fluted point technology is very well known in North America, evidenced by finds across the continent dating from 13,000 to 10,000 years ago. As lead author Dr. Rémy Crassard of the CNRS notes, “Until the early 2000s, these fluted points were unknown elsewhere on the planet. When the first isolated examples of these objects were recognized in Yemen, and more recently in Oman, we recognized that there could be huge implications.”

The sites of Manayzah and Ad-Dahariz yielded dozens of fluted points. The Arabian examples date to the Neolithic period, about 8,000 to 7,000 years ago, at least two thousand years later than the American examples. As Professor Petraglia of the Max Planck explains, “Given their age and the fact that the fluted points from America and Arabia are separated by thousands of kilometers, there is no possible cultural connection between them. This is then a clear and excellent example of cultural convergence, or independent invention in human history.”

The new PLOS ONE article carefully examines the fluted points found in south Arabia. Detailed technological analysis, backed up by stone tool experiments and replication by an expert modern flintknapper, illustrate the similarities between the American and Arabian fluting procedures.

In addition to the similarities, the authors of the new study also investigated the contrasts between the technologies of the two regions. Technological differences were apparent in the nature and location of the flute. The authors emphasize that the ‘fluting method’ was likely a mental conceptualization of stone tool manufacture, more than just a technical way to produce a projectile and hafting zone. Whereas the apparent function of fluting in the Americas is to facilitate hafting, or attaching the point to a shaft, most of the Arabian fluted points do not have hafting as a functional final aim. The fluting concept and the method itself are the same in both American and Arabia, yet the final aim of fluting appears to be different.

Arabian and American fluted point technologies were highly specialized stone tool production methods. The PLOS ONE study of Arabian fluting technology demonstrates that similar innovations and inventions were developed under different circumstances and that such highly-skilled and convergent production methods can have different anthropological implications. As discussed in the article, Professor McCorriston argues that “fluting in Arabia was used as a display of skill, rather than serving a purely functional purpose such as hafting, as is more widely accepted in the Americas.”

In Arabian prehistory, southern Arabia experienced developments of local origin, with multiple examples of inventions and innovations not culturally transmitted by outside traditions. The fluting method is then a hallmark of this indigenous development in the south Arabian Neolithic.

Ancient shell llama offering found in lake Titicaca

PENN STATE—A llama carved from a spondylus shell and a cylindrical laminated gold foil object were the contents of a carved stone box—an offering—found at the bottom of Lake Titicaca, according to researchers from Penn State and the Université libre de Bruxelles, Belgium. The offering, found near an island in the lake, was not located where others had found offerings in the past.

“We knew they (Inca) did some form of ritual offerings and that they did them in the lake,” said Jose Capriles, assistant professor of anthropology, Penn State. “The 16th and 17th century chronicles indicate there were submerged offerings.”

Lake Titicaca is located in the Andes between Bolivia and Peru. It is the largest lake in South America and was important to many cultures, including the Tiwanaku and the Inca.

Amateur divers in 1977 found other offerings, or artifacts that could be part of offering bundles near the Island of the Sun, but these were not intact offerings. Professional divers between 1988 and 1992 investigated the area of the Khoa reef and found pre-Inca and Inca artifacts including stone boxes with miniature figures. Recent excavations show that the Khoa reef was an important ceremonial site for the Inca and prior societies; however, this new group of artifacts was not found on the Khoa reef, but on the K’akaya reef.

Capriles and Christophe Delaere, junior research fellow, Université libre de Bruxelles, report their findings today (Aug. 4) in Antiquity.

“Since 2012, the Université libre de Bruxelles has implemented a research program with the goal of locating and inventorying the underwater heritage of Lake Titicaca,” said Delaere. “Our team has systematically surveyed around the islands and reefs in the Bolivian side of Lake Titicaca.”

The K’akaya Archipelago is west of Challapata Bay in the eastern shore of Lake Titicaca and is a series of a main island and three small ones. K’akaya reef is the last islet of the small chain and is covered in bird droppings.

The divers retrieved the box intact although currents had eroded one side. The box was tightly sealed, but not watertight. Resting in the box, beneath the silt that had filtered in, was the spondylus shell llama and the rolled gold foil.

One indication that these boxes contain artifacts valuable enough for offerings, beside the gold foil, is the spondylus shell llama. The closest location where the Inca could obtain this spiny oyster shell was in warm coastal ocean waters off the coast of Ecuador.

Finding this box in a new location suggests to the researchers that Lake Titicaca was a locus of ritual and ceremonial activity by the Inca. Similar offerings are found in other parts of what was the Inca Empire, some on land and some on water, but the researchers think that the lake was important in the consolidation of the empire.

According to Capriles, as the Inca radiated out from Cuzco in Peru, Lake Titicaca became a focal point. Prior archaeological evidence indicates that many of the islands, reefs and archipelagos contain ruins of temples and other monumental architecture.

“Most of what we know outside of archaeology is from the Spanish,” said Capriles. “Indications were that Lake Titicaca was a pilgrimage center for the Inca, but also served as a focal point for alliances with other groups.”

Spanish myths about the Inca dumping their gold into Lake Titicaca are apparently untrue, but the lake holds much more information still to be uncovered, said the researchers.

The artifacts reside with the Bolivian municipality of Escoma, which has jurisdiction over the area in which they were found.

“One of the goals of our underwater archaeological survey was to identify the existence of similar sites and to our surprise we found at least one,” said Delaere. “It presents not only one of the rare intact discoveries of an Inca underwater offering, but also that it was found at another place in the lake, which has an important implication for understanding the relationship between the expanding Inca empire, the local communities who lived in the lake, and Lake Titicaca itself prior to European contact.

“The inland underwater world remains largely unexplored and offers outstanding opportunities to understand prehistoric societies,” said Delaere. “The underwater heritage of Lake Titicaca still has many surprises to reveal.”

Cooling of Earth caused by eruptions, not meteors

TEXAS A&M UNIVERSITY—Ancient sediment found in a central Texas cave appears to solve the mystery of why the Earth cooled suddenly about 13,000 years ago, according to a research study co-authored by a Texas A&M University professor.

Michael Waters, director of The Center for The Study of the First Americans and Distinguished Professor at Texas A&M University, and colleagues from Baylor University and the University of Houston have had their work published in Science Advances.

Some researchers believed the event – which cooled the Earth by about 3 degrees Centigrade, a huge amount – was caused by an extraterrestrial impact with the Earth, such as a meteor collision.

But Waters and the team found that the evidence left in layers of sediment in Hall’s Cave were almost certainly the result of volcanic eruptions.

Waters said that Hall’s Cave, located in the Texas hill country, has a sediment record extending over 20,000 years and he first began researching the cave in 2017.

“It is an exceptional record that offers a unique opportunity for interdisciplinary cooperation to investigate a number of important research questions,” he said.

“One big question was, did an extraterrestrial impact occur near the end of the last ice age, about 13,000 years ago as the ice sheets covering Canada were melting, and cause an abrupt cooling that thrust the northern hemisphere back into the ice age for an extra 1,200 years?”

Waters and the team found that within the cave are layers of sediment, first identified by Thomas Stafford (Stafford Research Laboratories, Colorado), that dated to the time of the proposed impact that could answer the question and perhaps even identify the trigger that started the ancient cold snap.

The event also likely helped cause the extinction of large mammals such as mammoth, horse and camel that once roamed North America.

“This work shows that the geochemical signature associated with the cooling event is not unique but occurred four times between 9,000 and 15,000 years ago,” said Alan Brandon, professor of geosciences at University of Houston and head of the research team.

“Thus, the trigger for this cooling event didn’t come from space. Prior geochemical evidence for a large meteor exploding in the atmosphere instead reflects a period of major volcanic eruptions.

“I was skeptical,” Brandon said. “We took every avenue we could to come up with an alternative explanation, or even avoid, this conclusion. A volcanic eruption had been considered one possible explanation but was generally dismissed because there was no associated geochemical fingerprint.”

After a volcano erupts, the global spread of aerosols reflects incoming solar radiation away from Earth and may lead to global cooling post eruption for one to five years, depending on the size and timescales of the eruption, the team said.

“The Younger Dryas, which occurred about 13,000 years ago, disrupted distinct warming at the end of the last ice age,” said co-author Steven Forman, professor of geosciences at Baylor.

The Earth’s climate may have been at a tipping point at the end of Younger Dryas, possibly from the ice sheet discharge into the North Atlantic Ocean, enhanced snow cover and powerful volcanic eruptions that may have in combination led to intense Northern Hemisphere cooling, Forman said.

“This period of rapid cooling coincides with the extinction of a number of species, including camels and horses, and the appearance of the Clovis archaeological tradition,” said Waters.

Brandon and fellow University of Houston scientist Nan Sun completed the isotopic analysis of sediments collected from Hall’s Cave. They found that elements such as iridium, ruthenium, platinum, palladium and rhenium were not present in the correct proportions, meaning that a meteor or asteroid could not have caused the event.

“The isotope analysis and the relative proportion of the elements matched those that were found in previous volcanic gases,” said Sun, lead author of the report.

Volcanic eruptions cause their most severe cooling near the source, usually in the year of the eruption, with substantially less cooling in the years after the eruption, the team said.

The Younger Dryas cooling lasted about 1,200 years, “so a sole volcanic eruptive cause is an important initiating factor, but other Earth system changes, such as cooling of the oceans and more snow cover were needed to sustain this colder period, “Forman said.

Waters added that the bottom line is that “the chemical anomalies found in sediments dating to the beginning of the Younger Dryas are the result of volcanism and not an extraterrestrial impact.”

Most of Stonehenge’s Large Boulders Share Origin in West Woods, Wiltshire

Science Advances, AAAS—Most of the hulking sandstone boulders – called sarsens – that make up the United Kingdom’s famous Stonehenge monument appear to share a common origin 25 kilometers away in West Woods, Wiltshire, according to an analysis of the stones’ chemical composition. The findings support the theory that the stones were brought to Stonehenge at around the same time, contradicting a previous suggestion that one large sarsen, the Heel Stone, originated in the immediate vicinity of the monument and was erected earlier than the others. The results may also help scientists identify the route the monument’s ancient builders would have taken to transport the enormous rocks to their celebrated resting site. “Until recently we did not know it was possible to provenance a stone like sarsen,” says David Nash, the lead author of the study. “It has been really exciting to use 21st century science to understand the Neolithic past and answer a question that archaeologists have been debating for centuries.” Since technology for determining the origins of the enormous sarsens, which tower at up to 30 feet tall, weigh as much as 25 tons, and make up most of Stonehenge, did not exist until recently, most research has revolved around the monument’s smaller “bluestones” – various types of rock that clearly were not gathered locally. To learn where the behemoth boulders came from, Nash and colleagues used portable x-ray fluorescence spectrometry (PXRF) to initially characterize their chemical composition, then analyzed the data statistically to determine their degree of chemical variability. Next, the researchers performed inductively coupled plasma mass spectrometry (ICP-MS) and ICP-atomic emission spectrometry (ICP-AES) of samples from a core previously drilled through one sarsen stone and a range of sarsen boulders from across southern Britain. After comparing these signatures, Nash et al. were able to point to West Woods as the sarsens’ earliest home. The reason the monument’s builders selected this site remains a mystery, although the researchers suggest the size and quality of West Woods’ stones, and the ease with which the builders could access them, may have factored into the decision.

Accelerated bone deterioration in last 70 years places remains at famous Mesolithic peat bog in peril

PLOS—Alarming results from a 2019 survey of well-known archaeological site Ageröd reveal drastic bone and organic matter deterioration since the site’s initial excavations in the 1940s, suggesting action is needed to preserve findings from Ageröd and similar sites, according to a study* published July 29, 2020 in the open-access journal PLOS ONE by Adam Boethius from Lund University, Sweden, and colleagues.

Archaeologists need organic remains like bone and plant matter to reconstruct ancient human cultures and environments; however, organic matter is only preserved under specific conditions, becoming rarer as sites deteriorate due to environmental change like drainage and pollution. Boethius and colleagues here attempt to measure and analyze this phenomenon using the well-known Swedish Mesolithic peat bog site Ageröd I (8700-8200 cal BP), uncovered in the 1930s with excavations in the 1940s and 1970s, and renowned for its abundant and well-preserved quantities of bone and flint.

In 2019, the authors and colleagues excavated five test pits (five square meters total) at Ageröd, near areas containing the greatest number of remains as found in previous excavations. They then compared 61 bone, tooth, and antler fragments (as determined to the species or family level) uncovered in the test pits with 3716 bone fragments previously retrieved during the 1940s and 1970s excavations.

Osteological analyses of the bone remains from 2019 as compared with those found in the 1940s and 1970s indicate that bones at Ageröd have suffered accelerated deterioration over the last 75 years, with measured bone weathering averages going from 2.8 in the 40s (hard, heavy bones with occasional cracks) to 3.4 in the 70s (lighter bones with bigger cracks and interior exposure) to 3.7 in 2019 (light and heavily eroded bones, outer surface loss). More worryingly, complete destruction of some bones was suggested in this latest excavation, which uncovered no smaller fur game bones or bird bones, in contrast to earlier excavations–likely because small mammals and birds have smaller, lighter bones that break down faster than heavier bones. The authors also detected oxidized pyrite in the bones from 2019, in contrast to those from the 40s and 70s (which showed only non-oxidized pyrite). This suggests that oxygen was re-introduced into the bog environment between the 1970s excavations and 2019, destabilizing the typically anoxic bog conditions and permitting pyrite to oxidize and produce sulphuric acid (which drops soil pH and damages organic matter) as a by-product.

Although the 2019 excavation was much smaller in scope than previous excavations–in part to help limit further potential destruction at the site–the careful location of the test pits suggests the decay and loss of bone remains documented here is likely indicative of issues occurring across Ageröd. The authors note that Ageröd has not been subjected to more or heavier encroachment than most other archaeological sites, raising concerns as to the state of preservation in similar sites. They note that though Ageröd still holds significance, it has already lost many of its unique preservation properties–and if future steps to protect the site are not taken, then the organic remains preserved in its peat bog for 9000 years will soon be lost forever.

The authors add: “The fact is that we know very little of the state of our buried archaeological remains from most areas, but we are increasingly becoming aware of their rapid destruction. Unfortunately, this destruction is not only a matter of connecting the present with long lost ancient cultures or societies, as an interest of the ancient past. The record being destroyed is also a long-term perspective database which, if properly used, can help us create models of future environmental scenarios. Especially if going back to periods after the last Ice Age when the climate experienced rapid changes in global warming while human groups started to affect their local environment at much higher levels than previously seen. Unfortunately, the older the remains, the rarer and more vulnerable they become and if the pattern observed at Ageröd is similar in other areas we are in an extreme hurry to remedy the situation and recreate soils that allow organic preservation or, indeed, excavate the remains. If we do nothing, wait and hope for the best it is likely that the archaeo-organic remains in many areas will be gone in a decade or two. Once it is gone there is no going back and what is lost will be lost forever. It is worth considering, especially given recent advances in archaeological molecular science, i.e. aDNA and stable isotopes etc. If the organic remains deteriorate, these type of analyses will not be possible to do anymore and given the information we are now generating from them it will be a devastating blow to our understanding of ancient cultures, diet and subsistence strategies, migration and mobility etc.”

Lead white pigments on Andean drinking vessels provide new historical context

DICKINSON COLLEGE (Carlisle, Pa.) – Researchers studying lead white pigments on Andean ceremonial drinking vessels known as qeros have found new similarities among these artifacts that could help museums, conservators, historians and scholars better understand the timeline and production of these culturally significant items during the colonial period (1532-1821). In a study published in the journal Heritage Science, researchers used isotope measurements of lead white pigments in the decorative patterns on 20 colonial qeros to reveal linkages among vessels that were unknown previously.

The analysis identified only three isotope signatures among the lead white pigments decorating the qeros. Two of these isotopic signatures, present on a total of eight qeros, are the same as found in lead white paints used in European artwork from the same period. This match suggests these qeros are decorated with pigments imported to the Andes from Europe. The third signature, found on 12 of the qeros, suggests that the lead white was manufactured locally in the Andes.

The analysis was carried out by Allison Curley, a former Dickinson College undergraduate who is now a graduate student in earth & environmental sciences at the University of Michigan, and her mentor, geochemist Alyson Thibodeau, assistant professor of earth sciences at Dickinson, along with a team of researchers from the Smithsonian National Museum of the American Indian; the Metropolitan Museum of Art; the UCLA/Getty Program in Conservation of Archaeological and Ethnographic Materials; and the American Museum of Natural History.

“Little is known about the history of colonial qeros now in museum or private collections. The results could lead to a better understanding of the objects’ chronology and production,” explained Thibodeau. “For example, it is possible that qeros made earlier in the colonial period are decorated with European lead white, while qeros made later are decorated with lead white made from Andean ores. Further, the results strongly suggest some form of centralization in pigment acquisition, manufacture and distribution in the colonial period.”

“The consistency of the data was both surprising and satisfying,” said Curley, who has been collaborating with Thibodeau on this project since 2017. “It is exciting to see geochemistry provide insights into some longstanding historical and archaeological questions, and I was absolutely thrilled to present these findings to the Society for American Archaeology and to the conservators at the Smithsonian.”

“It’s important for those studying qeros all over the world to have a better understanding of the Andean people who made and used qeros during a time of colonial rule,” said Emily Kaplan, conservator for the Smithsonian National Museum of the American Indian, which has the largest collection of qeros in the United States. Kaplan hopes the research will lead to more radiocarbon dating, which will reveal more about the chronology of qero production. “Style and iconography have been used to help establish production timelines, but there’s a lot of guesswork involved,” she said.

Ceremonial drinking vessels have been used for toasting rituals in the Andes for millennia. Wooden qeros made in the colonial period were typically fabricated in identical pairs to make ceremonial toasts for social, political and religious occasions. These items retain their cultural significance to this day and are recognized as a symbol of the Inka Empire. Because they provide a window into the Andean indigenous colonial experience, qeros have been studied by art historians, archaeologists and anthropologists.

The study, “Isotopic composition of lead white pigments on qeros: implications for the chronology and production of Andean ritual drinking vessels during the colonial era,” is available online and is included in the Heritage Science collection, “Pigments, dyes, and colors in Latin American archaeometric investigations.”

Big brains and dexterous hands

UNIVERSITY OF ZURICH—People are very skilled with their hands, but take a very long time to learn various dexterous abilities. It takes babies generally around five months before they can purposely grip an object. Learning more complicated skills such as eating with fork and knife or tying one’s shoelaces can take another five to six years. By that age, many other primate species already have offspring of their own. Why do we take so much longer than our closest relatives to learn fine motor skills?

Brain development in primates follows fixed patterns

Sandra Heldstab, an evolutionary biologist in the Department of Anthropology at the University of Zurich, and her colleagues Karin Isler, Caroline Schuppli and Carel van Schaik observed 36 different primate species over a period of more than seven years to try to answer this question. She studied 128 young animals in 13 European zoos from birth until the age at which they had reached adult-level dexterity. What surprised her was that all species learned their respective manual skills in exactly the same order. “Our results show that the neural development follows extremely rigid patterns – even in primate species that differ greatly in other respects,” says Heldstab.

Large brain needed for dexterity

The researchers found, however, big differences in the specific fine motor skills of adults from different primate species. Large-brained species such as macaques, gorillas or chimpanzees can solve much more complex tasks using their hands than primates with small brains such as lemurs or marmosets. “It is no coincidence that we humans are so good at using our hands and using tools, our large brains made it possible. A big brain equals great dexterity,” says Heldstab.

Humans develop fine motor skills later than primates

Dexterity comes at a cost, however: In species with large brains like humans, it takes a long time for infants to learn even the simplest hand and finger movements. “It’s not just because we are learning more complex skills than lemurs or callitrichids, for example. It’s mainly because we do not begin learning these skills until much later,” says Heldstab. The researchers think that the reason for this may be that the larger brains of humans are less well developed at birth.

Essential to have enough time to learn

In addition, learning takes time and is inefficient, and it is the parents who pay for this until their offspring are independent. “Our study shows once again that in the course of evolution, only mammals that live a long time and have enough time to learn were able to develop a large brain and complex fine motor skills including the ability to use tools. This makes it clear why so few species could follow our path and why humans could become the most technologically accomplished organism on this planet,” concludes Sandra Heldstab.

Researchers find evidence of smallpox in the viking age

UNIVERSITY OF COPENHAGEN THE FACULTY OF HEALTH AND MEDICAL SCIENCES—The fatal disease smallpox is older and more widespread than scientists so far have proved. A new study by an international team of researchers from the University of Copenhagen and the University of Cambridge shows that the Vikings also suffered from smallpox.

Through the ages, the highly infectious disease smallpox has killed hundreds of millions of people. But it is unclear exactly when the disease emerged. There has been found evidence of smallpox from individuals from the 17th century while written records suggest the disease is much older.

Now a new study shows that the disease dates 1,000 years further back in time than previously shown. Researchers from the University of Copenhagen (UCPH) and the University of Cambridge have found proof that smallpox also existed in the Viking Age. The new results have been published in the scientific journal Science.

“We have found the oldest evidence of smallpox. Moreover, it seems to have been surprisingly common as early as in the Viking Age,” says Associate Professor Martin Sikora, Globe Institute, UCPH, and the University of Cambridge. He continues:

“Smallpox is the infection in the world that has killed most people. For that reason alone, it is very important and interesting to know how the disease developed. It gives us a unique opportunity to understand the viruses’ evolution: How did it change and become the pathogen that we know of today.”

Widespread in Northern Europe

The researchers have studied and analyzed the DNA of 13 individuals from Northern Europe infected with smallpox. The samples are 1,000 years older than the previous oldest sample known to have been infected based on ancient DNA, and they thus push the timeline for smallpox further back in time.

The study also shows the disease has been more widespread than previously assumed. The general idea used to be that smallpox was not endemic to Northern Europe during that time period.

“We show that not only was it endemic in Europe, but it was actually quite widespread in Northern Europe already at the year 600. That means that the disease was almost certainly far more established at a much earlier age than previously thought,” says Professor Eske Willerslev, Globe Institute, UCPH.

The researchers have also discovered that the viruses circulating during the Viking Age were distinct from their modern counterparts, and not directly ancestral to the viruses that caused the last big outbreak of smallpox in the 20th century.

“They share a common ancestor, but they also have unique features that differentiate them from the ones circulating later on in history. It turns out that the viruses we have found were some of these very, very early and different versions of the devastating pathogens known from the 20th century. It is the first time we can trace these early smallpox viruses and compare their genomes and mutations and see how the disease evolved over time,” says Eske Willerslev.

Catalogue of Mutations

Even though the disease has been eradicated today, it is still very useful to know how it developed and mutated through the ages.

Smallpox is a so-called poxvirus, a large family of viruses with many different types infecting a diverse set of host species. One such example is monkeypox, which typically infects monkeys but has also been known to cause a disease similar to smallpox in humans. It is therefore useful to known how other types of poxviruses mutate and survive.

“When we know how the disease mutated through time, it gives us an opportunity to put together a catalogue of how these pathogens might mutate in the future: What mutations and combinations make such a pathogen viable and successful? If they had those mutations in the past, they can most likely get them again.”

“It is one of a few examples where ancient genetic research has direct implications for present-day and future health,” says Martin Sikora.

Foxes have been eating humans’ leftovers for 42,000 years

PLOS—The diets of ancient foxes were influenced by humans, and these small carnivores might be tracers of human activity over time, according to a study* published July 22, 2020 in the open-access journal PLOS ONE by Chris Baumann of the University of Tübingen, Germany and colleagues.

Foxes love leftovers. In the wild, foxes regularly feed on scraps left behind by larger predators like bears and wolves, but the closer foxes live to human civilization, the more of their diet is made up of foods that humans leave behind. In this study, Baumann and colleagues hypothesized that if this commensal relationship goes back to ancient times, then foxes might be useful indicators of human impact in the past.

The authors compared ratios of Carbon and Nitrogen isotopes between the remains of various herbivores, large carnivores, and red and Arctic foxes from several archaeological sites in southwest Germany dating to the Middle and Upper Palaeolithic. At sites older than 42,000 years, when Neanderthals sparsely occupied the region, fox diets were similar to their local large carnivores. But in the younger sites, as Homo sapiens became common in the area, foxes developed a more unique diet consisting largely of reindeer, which are too big for foxes to hunt but which are known to have been important game for ancient humans of the time.

These results suggest that during the Upper Palaeolithic, these foxes made a shift from feeding on scraps left by local large predators to eating food left behind by humans. This indicates that foxes’ reliance on human food goes back a good 42,000 years. The authors propose that, with further studies investigating this fox-human relationship, ancient fox diets may be useful indicators of human impact on ecosystems over time.

The authors add: “Dietary reconstructions of Ice Age foxes have shown that early modern humans had an influence on the local ecosystem as early as 40,000 years ago. The more humans populated a particular region, the more the foxes adapted to them.”

Humans in America as much as 30,000 years ago, suggest scientists

University of Cambridge and University of Copenhagen—A cave in a remote part of Mexico was visited by humans around 30,000 years ago – 15,000 years earlier than people were previously thought to have reached the Americas.

Painstaking excavations of Chiquihuite Cave, located in a mountainous area in northern Mexico controlled by drug cartels, uncovered 1,900 stone tools from a small section of the high-altitude cave.

Archaeological analysis of the tools and DNA analysis of the sediment in the cave uncovered a new story of the colonization of the Americas which now traces evidence of the first Americans back to 25,000-30,000 years ago.

The results, which have been published in Nature today (July 22 2020), challenge the commonly held theory that the Clovis people were the first human inhabitants of the Americas 15,000 years ago.

DNA scientist Professor Eske Willerslev, of St John’s College, University of Cambridge, and director of The Lundbeck Foundation GeoGenetics Centre, University of Copenhagen, led the study with archaeologist Dr Ciprian Ardelean, of the University of Zacatecas in Mexico. 

Professor Willerslev said: “For decades people have passionately debated when the first humans entered the Americas. Chiquihuite Cave will create a lot more debate as it is the first site that dates the arrival of people to the continent to around 30,000 years ago – 15,000 years earlier than previously thought. These early visitors didn’t occupy the cave continuously, we think people spent part of the year there using it as a winter or summer shelter, or as a base to hunt during migration. This could be the Americas oldest ever hotel.”

The 10-year long research project raises more questions about the early humans who lived in the Americas than it solves.

Dr Ardelean said: “We don’t know who they were, where they came from or where they went. They are a complete enigma. We falsely assume that the indigenous populations in the Americas today are direct descendants from the earliest Americans, but now we do not think that is the case.

“By the time the famous Clovis population entered America, the very early Americans had disappeared thousands of years before. There could have been many failed colonizations that were lost in time and did not leave genetic traces in the population today.”

Chiquihuite Cave is a high-altitude site, 2750 meters above sea level. Nearly 2000 stone tools and small tool fragments, known as flakes, were discovered. DNA analysis of the plant and animal remains from the sediment packed around the tools in the cave dates the tools and the human occupation of the site to 25,000-30,000 years ago. Human DNA was not found which adds weight to the theory that the early people didn’t stay for long in the cave.

Dr Mikkel Winther Pedersen, a geneticist from the University of Copenhagen and one of the first authors of the paper, said: “We identified DNA from a wide range of animals including black bears, rodents, bats, voles and even kangaroo rats. We think these early people would probably have come back for a few months a year to exploit reoccurring natural resources available to them and then move on. Probably when herds of large mammals would have been in the area and who had little experience with humans so they would have been easy prey. The location of Chiquihuite Cave definitely rewrites what has conventionally been taught in history and archaeology and shows that we need to rethink where we look for sites of the earliest people in Americas.”

The Stone Tools

As far back as 30,000 years ago, humans had already developed techniques for producing tools. In this Mexican cave, researchers found 1,900 stone tools.

The unique feature of the Chiquihuite Cave is the “floor”, which consists of six layers of detritus and dust – all in all, a ten-foot column of ancient remains – which is so compressed and stable that by using various advanced measuring methods, it has been possible to date the layers one by one, from top to bottom.

Each layer has contained deposits of stone tools such as knives, scrapers and arrowheads, which the researchers have also been able to date.

“The cave finds are extremely interesting. These archaeological finds are so far the oldest in America. And the excavated stone tools are of a type unique to America,” Professor at Universidad Autónoma de Zacatecas, Mexico, Ciprian F. Ardelean, states.

Ice Cap Across North America

Until now, science has assumed that the earliest immigration to America took place approx. 15,000 years ago. At the time, a narrow opening in the ice along the northern Pacific coastline was created, which made it possible to walk from Siberia onto the American continent.

At the time, there were no other access routes to the continent, because North America was covered by a thick ice cap, which only later – approx. 13,000 years ago – melted enough to enable passage.

30,000 years ago, when the first stone tools were left in the Chiquihuite Cave, the massive ice cap had not yet covered all of North America, which means that it would have been possible to walk from Siberia and down through the American continent, Eske Willerslev explains.

 

The Chiquihuite Cave site is very difficult to reach and would have been a good vantage point for the early people to defend themselves from as they could look out for miles over the valley without being seen. It is in an area of Mexico that is now controlled by drugs cartels. The academics were escorted by armed police to the base of the mountain before they made their way up to the cave on foot.

Dr Pedersen said: “It was an unforgettable experience. It is a very unsafe place to travel so we were accompanied by Mexican police officers in armoured cars to the foot of the mountain. We left before sunrise to climb up to the cave so that we weren’t spotted.”

The visiting DNA scientists slept in the cave during their research visit and over the past 10 years Dr Ardelean has spent a number of months living in the cave to carry out the painstaking excavations.

Dr Ardelean added: “The peopling of the Americas is the last holy grail in modern archaeology. Unconventional sites need to be taken seriously and we need to go out and intentionally look for them. This site doesn’t solve anything, it just shows that these early sites exist. We are dealing with a handful of humans from thousands of years ago so we cannot expect the signals to be very clear. We have literally dug deeper than anyone has done in the past.”

The earliest human DNA from the Americas currently remains at 12,400 years ago, Dr Ardelean explained: “We have shown the previously long held date of human presence is not the oldest date for populating the Americas, it is the explosion date of populating the Americas.”

Professor Willerslev concluded: “I will never forget being part of this research, it was an unbelievable experience. The implications of these findings are as important, if not more important, than the finding itself. This is only the start of the next chapter in the hotly debated early peopling of the Americas.”

Neanderthals of Western Mediterranean did not become extinct because of changes in climate

UNIVERSITÀ DI BOLOGNA—Homo Neanderthalensis did not become extinct because of changes in climate. At least, this did not happen to the several Neanderthal groups that lived in the western Mediterranean 42,000 years ago. A research group of the University of Bologna came to this conclusion after a detailed paleoclimatic reconstruction of the last ice age through the analysis of stalagmites sampled from some caves in Apulia, Italy.

The researchers focused on the Murge karst plateau in Apulia, where Neanderthals and Homo sapiens coexisted for at least 3,000 years, from approximately 45,000 to 42,000 years ago. This study was published in Nature Ecology & Evolution. Data extracted from the stalagmites showed that climate changes that happened during that time span were not particularly significant. “Our study shows that this area of Apulia appears as a ‘climate niche’ during the transition from Neanderthals to Homo sapiens” explains Andrea Columbu, researcher and first author of this study. “It doesn’t seem possible that significant climate changes happened during that period, at least not impactful enough to cause the extinction of Neanderthals in Apulia and, by the same token, in similar areas of the Mediterranean”.

THE CLIMATE CHANGE HYPOTHESIS

The hypothesis that a changing climate was a factor in Neanderthals extinction (that happened in Europe nearly 42,000 years ago) found considerable support among the scientific community. According to this theory, during the last ice age, sharp and rapid changes in climate were a decisive factor in Neanderthals’ extinction because of the increasingly cold and dry weather.

We can find confirmation of these sharp changes in the analysis of ice cores from Greenland and from other paleoclimatic archives of continental Europe. However, when it comes to some Mediterranean areas where Neanderthals had lived since 100,000 years ago, the data tell a different story. The Western Mediterranean is rich in prehistoric findings and, until now, no one ever carried out a paleoclimatic reconstruction of these Neanderthal-occupied areas.

THE IMPORTANCE OF STALAGMITES

Where can we find answers about the past climate of the Western Mediterranean? The research group of the University of Bologna turned to the Murge plateau in Apulia. “Apulia is key to our understanding of anthropological movements: we know that both Neanderthals and Homo sapiens lived there approximately 45,000 years ago”, says Andrea Columbu. “Very few other areas in the world saw both species co-existing in a relatively small space. This makes the Murge plateau the perfect place to study the climate and the bio-cultural grounds of the transition from Neanderthal to Sapiens”.

How is it possible to provide a climate reconstruction of such a remote period? Stalagmites have the answer. These rock formations rise from the floor of karst caves thanks to ceiling water drippings. “Stalagmites are excellent paleoclimatic and paleoenvironmental archives”, explains Jo De Waele, research coordinator and professor at the University of Bologna. “Since stalagmites form through rainwater dripping, they provide unquestionable evidence of the presence or absence of rain. Moreover, they are made of calcite, which contains carbon and oxygen isotopes. The latter provide precise information about how the soil was and how much it rained during the formation period of stalagmites. We can then cross these pieces of information with radiometric dating, that provide an extremely precise reconstruction of the phases of stalagmites’ formation”.

A (RELATIVELY) STABLE CLIMATE

The pace at which stalagmites formed is the first significant result of this study. Researchers found out that Apulian stalagmites showed a consistent pace of dripping in the last and previous ice ages. This means that no abrupt change in climate happened during the millennia under investigation. A draught would have been visible in the stalagmites.

Among all the stalagmites that were analyzed, one was particularly relevant. Researchers sampled this 50-cm long stalagmite in the Pozzo Cucù cave, in the Castellana Grotte area (Bari) and they carried out 27 high-precision datings and 2,700 analyses of carbon and oxygen stable isotopes. According to dating, this stalagmite formed between 106,000 and 27,000 years ago. This stalagmite represents the longest timeline of the last ice age in the western Mediterranean and in Europe. Moreover, this stalagmite did not show any trace of abrupt changes in climate that might have caused Neanderthals’ extinction.

“The analyses we carried out show little variation in rainfall between 50,000 and 27,000 years ago, the extent of this variation is not enough to cause alterations in the flora inhabiting the environment above the cave”, says Jo De Waele. “Carbon isotopes show that the bio-productivity of the soil remained all in all consistent during this period that includes the 3,000 years-long coexistence between Sapiens and Neanderthals. This means that significant changes in flora and thus in climate did not happen”.

THE TECHNOLOGY HYPOTHESIS

The results seem to show that the dramatic changes in the climate of the last ice age had a different impact on the Mediterranean area than in continental Europe and Greenland. This may rule out the hypothesis that climate changes are responsible for Neanderthals dying out.

How do we explain their extinction after a few millennia of coexistence with Homo sapiens? Stefano Benazzi, a palaeontologist at the University of Bologna and one of the authors of the paper, provides an answer to this question. “The results we obtained corroborate the hypothesis, put forward by many scholars, that the extinction of Neanderthals had to do with technology”, says Benazzi. “According to this hypothesis, the Homo sapiens hunted using a technology that was far more advanced than Neanderthals’, and this represented a primary reason to Sapiens’ supremacy over Neanderthals, that eventually became extinct after 3,000 years of co-existence”.

Breakthrough in studying ancient DNA from Doggerland that separates the UK from Europe

UNIVERSITY OF WARWICK—Thousands of years ago the UK was physically joined to the rest of Europe through an area known as Doggerland. However, a marine inundation took place during the mid-holocene, separating the British landmass from the rest of Europe, which is now covered by the North Sea.

Scientists from the School of Life Sciences at the University of Warwick have studied sedimentary ancient DNA (sedaDNA) from sediment deposits in the southern North Sea, an area which has not previously been linked to a tsunami that occurred 8150 years ago.

The paper, led by the University of Bradford and involving Universities of Warwick, Wales St. Trinity David, St. Andrews, Cork, Aberystwyth, Tartu as well as the Smithsonian and Natural History Museum, ‘Multi-Proxy Characterisation of the Storegga Tsunami and Its Impact on the Early Holocene Landscapes of the Southern North Sea’, published in the Journal Geosciences, sees Life Scientists from the University of Warwick work specifically on the sedimentary ancient DNA from Doggerland.

A number of innovative breakthroughs were achieved by the University of Warwick scientists in terms of analysing the sedaDNA. One of these was the concept of biogenomic mass, where for the first time they were able to see the how the biomass changes with events, evidence of this presented in the paper refers to the large woody mass of trees from the tsunami found in the DNA of the ancient sediment.

New ways of authenticating the sedaDNA were also developed, as current methods of authentication do not apply to sedaDNA which has been damaged whilst under the sea for thousands of years because there is too little information for each individual species. Researchers therefore came up with a new way, metagenomic assessment methodology, whereby the characteristic damage found at the ends of ancient DNA molecules is collectively analyzed across all species rather than one.

Alongside this a key part of analyzing the sedaDNA is to determine whether or not it was deposited in situ or has moved over time. This led researchers to develop statistical methods to establish which scenario was appropriate, using stratigraphic integrity they were able to determine that the sedaDNA in the sediment deposits had not moved a massive amount since deposition by assessing the biomolecules vertical movement in the core column of the sedaDNA.

Identifying which organisms the ancient fragmented molecules of DNA came from is also challenging because often there is nothing to directly compare. In a fourth innovation the researchers refined algorithms to define these regions of “dark phylogenetic space” from where organisms must have originated overcome this issue.

Professor Robin Allaby from the School of Life Sciences at the University of Warwick comments: “This study represents an exciting milestone for sedimentary ancient DNA studies establishing a number of breakthrough methods to reconstruct an 8,150 year old environmental catastrophe in the lands that existed before the North Sea flooded them away into history.”

Professor Vince Gaffney from the School of Archaeological and Forensic Sciences at the University of Bradford said: “Exploring Doggerland, the lost landscape underneath the North Sea, is one of the last great archaeological challenges in Europe. This work demonstrates that an interdisciplinary team of archaeologists and scientists can bring this landscape back to life and even throw new light on one of prehistory’s great natural disasters, the Storegga Tsunami.

“The events leading up to the Storegga tsunami have many similarities to those of today. Climate is changing and this impacts on many aspects of society, especially in coastal locations.”

Rewriting history: New evidence challenges Euro-centric narrative of early colonization

WASHINGTON UNIVERSITY IN ST. LOUIS—In American history, we learn that the arrival of Spanish explorers led by Hernando de Soto in the 1500s was a watershed moment resulting in the collapse of Indigenous tribes and traditions across the southeastern United States.

While these expeditions unquestionably resulted in the deaths of countless Indigenous people and the relocation of remaining tribes, new research from Washington University in St. Louis provides evidence that Indigenous people in Oconee Valley — present-day central Georgia — continued to live and actively resist European influence for nearly 150 years.

The findings, published July 15 in American Antiquity, speak to the resistance and resilience of Indigenous people in the face of European insurgence, said Jacob Lulewicz, a lecturer in archaeology in Arts & Sciences and lead author.

“The case study presented in our paper reframes the historical contexts of early colonial encounters in the Oconee Valley by way of highlighting the longevity and endurance of Indigenous Mississippian traditions and rewriting narratives of interactions between Spanish colonizers and Native Americans,” Lulewicz said.

It also draws into question the motives behind early explanations and interpretations that Euro-Americans proposed about Indigenous earthen mounds — platforms built out of soil, clay and stone that were used for important ceremonies and rituals.

‘Myths were purposively racist’

“By the mid-1700s, less than 100 years after the abandonment of the Dyar mound [now submerged under Lake Oconee], explanations for the non-Indigenous origins of earthen mounds were being espoused. As less than 100 years would have passed between the Indigenous use of mounds and these explanations, it could be argued that the motives for these myths were purposively racist, denying what would have been a recent collective memory of Indigenous use in favor of explanations that stole, and disenfranchised, these histories from contemporary Indigenous peoples,” Lulewicz said.

The Dyar mound was excavated by University of Georgia archaeologists in the 1970s to make way for a dam. Lulewicz and co-authors — Victor D. Thompson, professor of archaeology and director of the Laboratory of Archaeology at the University of Georgia; James Wettstaed, archaeologist at Chattahoochee-Oconee National Forests; and Mark Williams, director emeritus of the Laboratory of Archaeology at the University of Georgia — received funding from the USDA Forest Service to re-date the platform mound, which contained classic markers of Indigenous rituals and ceremonies.

Using advanced radiocarbon dating techniques and complex statistical models, modern-day archaeologists are able to effectively construct high-resolution, high-precision chronologies. In many cases, they can determine, within a 10- to 20-year range, dates of things that happened as far back as 1,000 years ago.

“Radiocarbon dating is really important, not just for getting a date to see when things happened, but for understanding the tempo of how things changed throughout time and really understanding the complex histories of people over hundreds of years,” Lulewicz said. “In archaeology, it’s really easy to group things in long periods of time, but it would be false to say that nothing changed over those 500 years.”

Their research yielded 20 new dates from up and down the mound, which provided a refined perspective on the effects that early Indigenous-colonizer encounters did, and did not, have on the Indigenous people and their traditions.

Missing from the mound was any sign of European artifacts, which is one of the reasons why archaeologists originally believed sites in the region were abruptly abandoned just after their first encounters with Spanish colonizers. “Not only did the ancestors of Muscogee (Creek) people continue their traditions atop the Dyar mound for nearly 150 years after these encounters, but they also actively rejected European things,” Lulewicz said.

According to Lulewicz, the Dyar mound does not represent an isolated hold-over after contact with European colonizers. There are several examples of platform mounds that were used beyond the 16th century, including the Fatherland site associated with the Natchez in Louisiana, Cofitachequi in South Carolina and a range of towns throughout the Lower Mississippi Valley.

“However, the mound at Dyar represents one of the only confirmed examples, via absolute dating, of continued Mississippian traditions related to mound-use and construction to date.”

Today, members of the Muscogee (Creek) Nation, descendants of the Mississippians who built platform mounds like the one at Dyar, live in Oklahoma. “We have a great, collaborative relationship with archaeologists of the Muscogee (Creek) Nation Historic and Cultural Preservation Department, so we sent them the paper to review. It was really well received. They saw, reflected in that paper, a lot of the traditions they still practice in Oklahoma and were generous enough to contribute commentary that bolstered the results presented in the paper,” he said.

“This is where the archaeology that we write becomes so important in the present. … Without this type of work, we are contributing to the disenfranchisement of Indigenous peoples from their history.”

“Of course, they already knew many of the things we ‘discovered,’ but it was still meaningful to be able to reaffirm their ancestral link to the land.”

In the end, Lulewicz said this is the most important part of the paper. “We are writing about real human lives — Indigenous lives that we have historically treated very poorly and who continue to be treated poorly today in some cases. With the use of advanced radiocarbon dating and the development of really high resolution chronologies, we are able to more effectively reinject lives into narratives of the past.”

Fecal Biomarkers Confirm That Ancient Humans Left Behind Fossilized Poop in Oregon’s Paisley Caves

Science Advances—Fecal biomarkers confirm that fossilized feces discovered in Oregon’s Paisley Caves originated from humans, with some samples dating back more than 12,000 years, according to a new study. While previous mitochondrial DNA (mtDNA) analyses suggested the specimens came from some of the earliest humans to occupy the Americas, Lisa-Marie Shillito and colleagues provide greater certainty about the ancient turds’ identities by analyzing lipid biomarkers, which are less sensitive to contamination, although they provide less detailed information. The researchers conclude that both methods – analyzing mitochondrial DNA and lipid biomarkers – may be used in tandem as scientists search prehistoric poo for clues about when the first people arrived in the Americas, how they got here, and how they adapted to its varying terrain. Dung samples such as those from Paisley Caves can help fill in the blanks about the lives of ancient humans when skeletal remains are scarce. Earlier studies of some of the dung samples were called into question since some of the mtDNA recovered from them could have leached into the samples from later occupants of the cave who defecated there, or it could have been derived from other species that used the cave. To explore whether lipid biomarkers in the fossilized feces could help solve the mystery of who deposited them in the cave, Shllito et al. sampled 21 specimens that were previously identified through mtDNA analysis to determine their sterol and bile acid content. They next compared lipids derived from one dung sample with lipids from the surrounding sediment, finding distinctly different distributions that suggest minimal leaching occurred between the dung and its environment. Ultimately, the researchers found that the identities of 13 of the fossilized feces agreed with previously reported classifications based on mitochondrial DNA, the majority of which came from humans. The oldest dated back to about 12,200 years ago, demonstrating that humans have occupied the Paisley Caves since at least that time. The findings support the theory that humans first settled in America before the arrival of the ancient Clovis people, who were long thought to be the ancestors of the indigenous peoples of the Americas.

Hyksos, 15th Dynasty rulers of Ancient Egypt, were an internal takeover

PLOS—The Hyksos, who ruled during the 15th Dynasty of ancient Egypt, were not foreign invaders, but a group who rose to power from within, according to a study* published July 8, 2020 in the open-access journal PLOS ONE by Chris Stantis of Bournemouth University, UK and colleagues.

The Hyksos were a foreign dynasty that ruled parts of Egypt between approximately 1638-1530 BCE, the first instance of Egypt being ruled by individuals of a foreign origin. The common story is that the Hyksos were invaders from a far-off land, but this idea has been drawn into question. Archaeological evidence does link Hyksos culture with an origin in the Near East, but exactly how they rose to power is unclear.

In this study, Stantis and colleagues collected enamel samples from the teeth of 75 humans buried in the ancient Hyksos capital city of Tell el-Dab’a in the northeast Nile Delta. Comparing ratios of strontium isotopes in the teeth to environmental isotope signatures from Egypt and elsewhere, they assessed the geographic origins of the individuals who lived in the city. They found that a large percentage of the populace were non-locals who immigrated from a wide variety of other places. This pattern was true both before and during the Hyksos dynasty.

This pattern does not match the story of a sudden invasion from a single far-off land, but of a multi-cultural region where one internal group – the Hyksos – eventually rose to power after living there for generations. This is the first study to use archaeological chemistry to address the origins of the Hyksos rulers, but the authors note that more investigations and broader chemical techniques will be needed to identify the specific ancestries of the Hyksos and other non-local residents of Egypt.

Stantis adds: “Archaeological chemistry, specifically isotopic analysis, shows us first-generation migration during a time of major cultural transformations in ancient Egypt. Rather than the old scholastic theories of invasion, we see more people, especially women, migrating to Egypt before Hyksos rule, suggesting economic and cultural changes leading to foreign rule rather than violence.”

The Remarkable Skulls of Drimolen

Stephanie Baker is a researcher at the Palaeo-Research Institute at the University of Johannesburg, South Africa, and director of excavations and research at Drimolen.

South Africa has been a hotspot of fossil discovery since the first human ancestor fossil was found in the Taung (formerly Buxton-Norlim) Limeworks in 1924. The original discovery of the now famous Taung Child began a fossil journey that found its peak in a small area just north of Johannesburg, South Africa, now known as the Cradle of Humankind and recognized as a UNESCO World Heritage Site. One of the first fossils discovered in the Cradle area, in 1938, was a partial skull (first found by a young boy, Gert Terblanche, who lived on the Kromdraai Farm) that Dr Robert Broom assigned to the species Paranthropus robustus.

Some 50 years later, another important Paranthropus site was discovered by Dr Andre Keyser, a South African palaeontologist and geologist — the Drimolen Fossil Site. The site is located almost directly in the middle of the demarcated Cradle boundaries and very quickly proved to be a site of high significance. After two years of excavation, Keyser discovered a pair of crania, designated DNH 7 and DNH 8 (or more romantically, Euridice and Orpheus, respectively). DNH 7 is the most complete cranium of the species thus far discovered and DNH 8 is a well preserved large male mandible with teeth. DNH 7 has become particularly significant since it was discovered that she was, in fact, a she. This was important because up until her discovery in 1994 and subsequent description in 2000, no other well-preserved crania of female Paranthropus had been discovered. Her diminutive, sagittal crestlacking head gave scientists much needed insight into the sexual dimorphism of Paranthropus robustus and led to changing our understanding of the species’ lifestyles.

Since the initial description of DNH 7, multiple specimens of both Paranthropus and early Homo have been discovered here, making Drimolen one of the richest hominin-bearing deposits in South Africa. The site is geologically quite simple, unlike some of our neighboring sites, which feature multiple infills and members. The Drimolen deposit is made up of only one simple phreatic maze cave chamber, now exposed through years of surface erosion and later lime miner activity. The fossil deposits are clustered mainly along the western edge of the cave walls, where large breccia blocks and pinnacles still stand today, preserving clues of the original infill shape and cave entrance. Mining activity created what is now called the Central Excavation Area (CEA), where one large breccia block, formerly from the cave ceiling, is surrounded by decalcified sediments that are essentially ex situ. These deposits were the focus of the bulk of all previous excavations, directed by both Keyser and, later, Colin Menter.

DNH 134 and the Implications

I first joined the project in 2011 as a student assistant and assumed the permit fully in 2017, alongside my co-permit holder, Prof Andy Herries. With this changeover in permit holders came a changeover in approach to the excavations. The primary area of focus moved to the western edges of the cave wall, both in the CEA and over the back of the pinnacle row. This change heralded a flurry of new discoveries of extremely well-preserved hominin fossils, including the recently published DNH 152 Paranthropus robustus male specimen.

That publication included a second specimen of great importance — DNH 134. This  find is now described as the oldest Homo erectus specimen in the world (at 1.95 to 2.04 million years old), as well as the first recorded representative of the species in South Africa. DNH 134 has a fascinating discovery story and illustrates the complexity of the excavations, the difficulty of working with such highly fragmentary fossils, as well as the importance of including young researchers and students in major analysis. In June of 2015, the University of Johannesburg and La Trobe University palaeo-anthropological field season was underway. Students (both under- and postgraduate) had travelled to South Africa for the opportunity of field training and excavation experience at Drimolen. One of these students, Richard Curtis, was excavating a small area in the south west corner of the CEA when he began uncovering a cluster of skull fragments. The fragments were not immediately identifiable beyond saying they came from a skull. With this, I began the in-field reconstruction of this ancient puzzle.

It took a good number of days working alongside Richard to recover more fragments before some semblance of a shape took place. Eventually, I had two larger pieces with which to work. One was clearly the base of the cranium: the occipital and part of the foramen magnum. The other was the top of the skull. At first, there was no obvious link between these fragments — until one day, after Richard had collected a number of cranial pieces in a chunk of sediment. I sat that evening at the far end of the field school site dinner table, fully engrossed in my puzzle and completely ignoring the lecture happening at the other end of the room. One of the remarkably uninteresting and amorphous blob fragments recovered from the ground that same day turned out to be the bridge that linked the two larger fragments I had reconstructed. In that wonderful eureka moment, as the two pieces came together, I gasped — apparently far louder than I had intended, as the aforementioned lecture came to a very swift halt.

It was immediately clear that the small skull was that of a hominin, not of a baboon, as had previously been suggested along with buck, hyaena, and others. The next step was to figure out: what kind of hominin? Thereafter, the skull was entrusted to Jesse Martin, now a PhD candidate at La Trobe University in Melbourne Australia. After much comparison work in the Phillip V Tobias Fossil Hominid vault at the University of the Witwatersrand, Jesse made a difficult phone call to the rest of us. He found that the DNH 134 cranium was actually Homo erectus. We laughed, at first. Homo erectus had never been found in South Africa before and the likelihood that we would find it at Drimolen was low. At the time, we also didn’t have the absolute dates for the site, so we believed the deposit to be around 1.8 million years old, and some estimates had it even younger at around 1.5 million. By this time in the fossil record, Homo ergaster (the African cousin to erectus) was quite solidly established in East African, with beautiful specimens such as Nariokotome Boy (KNM-WT 15000; c. 1.6-1.5 Ma from Lake Turkana, Kenya), among others.

But after he fought his case, we were convinced! The overall cranial shape was convincingly Homo erectus. When viewed from above, it has the characteristic teardrop shape seen in all Homo erectus specimens. This shape is indicative of the beginnings of the larger, reorganized brain we see in modern examples of the genus Homo, to which modern humans belong, along with other Homo species. The brain size (~538 cc) is on the high end compared to both Australopithecus and Paranthropus, despite this specimen representing an individual juvenile.  The brain size is smaller than the Mojokerto child from Indonesia (~630cc), a specimen of similar developmental age but much younger geologically (~1.8-1.2 Ma). This suggests that while the brain shape is forming early in the evolution of Homo erectus morphology, the size increase develops later.

Homo erectus is well-represented in the fossil record but also well-sampled from across many continents. They were highly adaptive and capable of transitioning across numerous diverse landscapes in very short – geologically speaking – periods of time. Discovering Homo erectus in southern Africa is another indicator that, firstly, we need to constantly be rethinking our understanding of human evolution, and secondly, it reconfirms this species’ incredible adaptive abilities. The next oldest location where Homo erectus was discovered—the famous Dmanisi site in the Republic of Georgia—was dated to approximately 1.8 Ma. These specimens, mostly adults, are a good 11 thousand kilometers away from Drimolen. It suggests that this species’ journey out of Africa took place in less that 200 thousand years, considered an unprecedented trip for early Pleistocene apes. This implies a high level of survivability, adaptability and certainly a good dose of curiosity.

Our Next Steps

Moving forward, the Drimolen team hopes to add to the sample. DNH 134 is a small child of around 1-3 years old, so recovering an adult specimen would be excellent. Adding to the Homo erectus finds at the site will aid to understanding the species and its evolution in southern Africa. We also need to go back through the hominin collection amassed thus far from the site and reassess some of those specimens previously assigned simply to ‘early Homo’. Even more important, the team hopes to work through a lot of the other fauna excavated from the site since its’ discovery in 1992. Each excavated fossil adds to our understanding of how Homo erectus, Paranthropus robustus and late-occurring Australopithecus all navigated this transitional landscape. We know that the environment was shifting over this time, so it marks a critical moment in our evolutionary history, potentially impacting the next step in the journey to becoming human.

Arianna Zakrzewski is an intern and writer for Popular Archaeology. She is also a graduate from Rhode Island College with a Bachelor’s degree in Anthropology. She has had an interest in archaeology since elementary school, specifically Egyptology and the Classics. In recent years, she has also gained an interest in historical archaeology, and has spent time in the field working in St. Mary’s City, Maryland, participating in excavation and archival research. Most recently, she completed her MA in Museum Studies from Johns Hopkins University. She is currently focused on collections management and making archaeological discoveries accessible and exciting to the public.

When one thinks of prehistoric Native Americans, an image of small, mobile groups or tribes of hunter-gatherers immediately comes to mind. In truth, however, they were also very much a society of farmers, making their living within permanent settlements where a variety of crops or domesticated plants were grown and harvested. Now, a collaborative study conducted by researchers from the University of Connecticut (UConn), the University of Utah, Troy University, and California State University, Sacramento is examining the growth in agriculture 7,500 to 5,000 years ago among the ancient Native Americans and the social implications of this shift. The study focuses on the interior part of Eastern North America.

“There’s no good name for the region really, because it’s part of the lower mid-west and upper south east,” explains researcher and Ph.D. student Elic Weitzel of UConn. “We’re talking about states like Tennessee, Missouri, Illinois, Kentucky, Ohio—this general region.” Such a study has never been conducted before.

Weitzel is pursuing a Ph.D. in anthropology, and although he is trained as an archaeologist, he thinks of himself as more of a “human ecologist.” Weitzel, along with his research team, have used pre-existing data sets collected by archaeologists over the years to reexamine this region and ask new questions about the growth and development of agriculture and the ways in which this shift changed the social climate of a region. “The cool thing about this research is that we didn’t actually do any excavations,” he explains. “This is all based on previous studies that archaeologists have done, and it’s part of this push toward big data in science disciplines at large. Archaeologists seem to be amassing these large data sets, and because of that increasing cooperation among researchers, people like me and my colleagues can now ‘mine’ that data and reanalyze things on a broader scale than any individual archaeologist would have been able to do in years past.”

Growth in agriculture

Using these existing data sets in archaeology and ecology, the research team examined the region and found that in using the ecological model, they were able to predict where prehistoric individuals should live on a landscape in relation to population density and the quality of different habitats. “We really applied that kind of ecological model to the archaeological data sets of where humans were living in the past on the landscape,” Weitzel explains. “What this predicts is that as the population density in an area increases, people are going to first live in the highest quality locations on the landscape. As the population density grows there, they are going to expand to the second highest quality location, and then the third highest quality location.” This pattern is what is observed before the introduction of farming in the region. It was a hunter-gatherer pattern of infilling the landscape.

“Then, when you have farming, there’s a bit of a reversal of that pattern,” Weitzel goes on. “All of the sudden you’ve got this new economic activity that really requires people to cooperate with each other. People start moving back into those high-quality locations they had previously left, so we see this actual increase with the metric of site quality that we see in the data.” With the shift toward farming taking place 7-7.5 thousand years ago came an incentive to live closer to other people and cooperate with other people in order to manage and maintain crops. “We used this ecological, theoretical model to make these predictions, and then looked at the locations of the sites themselves in reference to what’s called ‘net primary productivity,’” Weitzel explains. “This is essentially just the measure of energy availability in an environment. Essentially plants photosynthesize to produce energy, and you can do all sorts of things with satellite imagery nowadays where we can run these calculations and end up with an image of a landscape with net primary productivity calculated for all these different cells in this kind of image. We use that data and look where the sites were located, and just statistically analyzed the changes through time, and our findings really fit very well with this theoretical model that we came at it from.”

Some of the crops being domesticated by these groups would be familiar to people now, such as squash and sunflowers, but many other domesticated plants in this region still exist on the landscape in their wild forms and are unrecognizable to modern humans. “The nature of these plants was such that they were really best harvested quickly in the autumn, and so that’s what inspired this shift towards a new incentive to cooperate with people,” he explains. “Certainly, folks are always cooperating, but now that you’re trying to target crops, that inspires the shift toward [the greater] cooperation that we see.” But as we shift to domesticating and harvesting crops, we see several moving parts in these societies shift as well, namely the new need for defense. “Now that you’re targeting these crops that are on fixed locations on the landscape—unlike the animal population that moves around—you’ve got to start defending these crops, and your territory as a result.” Along with cooperation comes new forms of competition as well. “People are now defending their territories, they’re attacking other people, they’re launching raiding parties and they’re scalping and beheading and taking trophies from battle,” Weitzel goes on. “These two broad umbrellas of cooperation and competition really frame a lot of the later social changes that occurred within Native American society for a millennium afterwards. It is right at this time that you are also seeing a lot of shifts more broadly in how people are organizing themselves. A little later after this point in time is when you start seeing the appearance of social complexities and social hierarchy, and eventually later on you’ve got your famous Mississippian civilizations with their famous mound sites, but all of these changes are really undergirded by the more fundamental shift that occurred thousands of years earlier in the form of domestication and the management of crops that really lead to these two changes in cooperative and competitive dynamics.”

Increase in inter-group violence

As these changes in cooperative and competitive dynamics come about, we can also observe an increase in violence, suggest the researchers. “With that shift toward becoming a farmer, we expected that sites were actually going to start aggregating together on the landscape, kind of clustering, and might be doing so in these high-quality locations,” Weitzel says. “Where they’re living on the landscape and how clustered and in which types of habitats they are can actually tell you something about how common-place it is for interpersonal cooperation, or perhaps intergroup competition at the same time.” By analyzing the available data, specifically the site distributions, the research team was able to pull together a data set on the frequency of “trophy taking” in the archaeological record. Trophy taking includes actions such as scalping, beheading, or dismemberment of some sort. Weitzel explains, “[With] certain groups, after some kind of battle would take place, a fight or conflict, the victors would remove body parts from the losers as a symbol that they won, and they were good warriors and fighters. The frequency of trophy taking in the archaeological record really coincides perfectly with the changes that we’re seeing in settlement patterns around 7-7.5 thousand years ago.” Evidence suggests that hunter-gatherer groups engaged in raiding and intergroup violence in North America, but there is no evidence that is known to us yet for this clear signature of trophy taking. “Before that [7-7.5 thousand years ago] you’ve got fractures and broken bones and imbedded projectile points, so there is violence for sure going on, but archaeologists have for a while now thought that there’s something different going on when you see this appearance of trophy taking.”

Much of the theoretical modeling of this study is informed by evolutionary theory, or the Darwinian idea of adaptation and fitness, according to Weitzel. The way people distribute themselves as a population across the landscape has to do with the individual choices people make based on their fitness, their reproductive success, the quality of the environment, and the access and opportunities available to them. “That kind of evolutionary thinking that we would apply to humans is often emphasized competitively, through violence and interpersonal competition and group competition, but it’s really important for us to remember that cooperation is just as important in terms of human evolution and human adaptation as competition is,” he says. These two dynamics, competition and cooperation, are fundamentally important and go hand in hand. “We are profoundly good at violence. There is, of course, a lot of discussion on this. We are capable of incredible, horrific acts of violence, but simultaneously, we are capable of incredible acts of cooperation. We must understand that these things are really two sides of the same coin; cooperation with your group members is often times necessary to compete with outsiders. That is the broader narrative here, and that’s the really important thing to remember.”

While the recently published study focuses heavily on this time period of 7-7.5 thousand years ago, Weitzel points out that around 3,000 years ago, we see a reversal of this pattern. “We suddenly start to see people leaving those high-quality locations, and we start to see almost the absence of trophy taking whatsoever.” Between 1-3,000 years ago, trophy taking becomes incredibly rare in comparison, and we can observe a shift in the region that seems to have alleviated some of the pressure on these groups as people start expanding into lower quality habitats and group violence is no longer as prominent in the material record.

 

Because the data in this study is being pulled and reanalyzed from previous work, no excavations are necessary to further this research. However, this team has plans to continue working with these large databases to investigate these questions further. Weitzel says, “There are a lot of great questions to be asked about the shift from foraging to farming in terms of how exactly this cooperation was maintained, because it’s tough to get a bunch of people on the same page, doing the same thing at certain times. In this time when we are seeing this shift, there is actually no clear evidence yet for a strong social hierarchy, so this is a bit more of a social heterarchy—a kid of less vertically structured and more horizontally structured system. This really interesting question can be asked about how exactly they were cooperating and overcoming these collective action problems they were faced with when trying to cooperate, and that’s something that I’m really interested in looking into in the future.”

The Herculaneum Papyri

For years after England’s defeat of the French in Egypt, ancient Egyptian artifacts streamed into England. The most famous of these, the Rosetta Stone, was unveiled in 1802; in 1808, the architect Sir John Soane famously gutted his Holborn residence, creating a top-lit, three-story void, at the bottom of which reposed an Egyptian sarcophagus, glittering with traces of its original gilt. But not every dislocated artifact enjoyed such a celebratory reception. Smaller, less attention-grabbing items also circulated, mainly among specialists and antiquarians, providing less spectacular but arguably more meaningful opportunities for scholars to engage with the ancient past.

One of these modest artifacts was a cache of carbonized papyri scrolls discovered in the ruins of Herculaneum. Found in Naples when the city became an English protectorate, the rolls came to the attention of the Prince of Wales who, during the six years of English rule that followed, spearheaded an effort to unroll and transcribe them. He selected the Reverend John Hayter, future chaplain to George IV, to oversee the project. In 1800, Hayter claimed to have opened two hundred of the charred scrolls. Two assistants, Carlo Orazj and Giuseppe Casanova, produced apographs (scribal facsimiles) of some, if not all, of them.

When the French reconquered Naples in 1806, the court absconded to Palermo with the apographs. In August 1807, the newly appointed English plenipotentiary to the area, William Drummond, convinced the court at Palermo to hand them over.  He passed them to Hayter, who managed to engrave only part of one. This disappointing performance may have reflected the encroachment of other interests, since a year later Drummond excoriated him for his involvement in a series of sexual scandals, including one involving a Neapolitan baron’s daughter. “I am sick of the stories of your battles in the brothels,” Drummond griped, not omitting to point out that even while at Naples, Hayter had opened only half as many scrolls as he had claimed. After dismissing Hayter, Drummond convinced the court to allow the apographs to be sent to England for publication under the auspices of their longtime royal champion the Prince of Wales, who transferred them to Oxford, where they remain.

Meanwhile, a set of similar scrolls had come to the attention of one Thomas Young. Young [pictured right], who eventually made a serious bid to decipher the Egyptian hieroglyphs, was at this time merely an up-and-coming London physician and occasionally dabbler in ancient scripts. A handful of people, including officials from the Royal Society and the British Museum, were attempting to determine the best method of unrolling the papyri, and Young was selected to assist. His medical and scientific training were particular points of favor, for he was known “to have formerly employed himself in minute anatomy” and had considerable skill in experimental physics and chemistry.

Working on the scrolls, Young experienced firsthand the physicality of an ancient object. The scrolls’ recalcitrant forms, their materiality, demanded his dexterity, honed from years of painstaking anatomical dissection and experimental work. He was no less dexterous in making sense of these ancient linguistic remains by linking their spatial dispositions to meaning. These methods carried forward into his engagement with Egyptian hieroglyphs.

To unroll the papyri, Young devised a method that drew on his anatomical expertise. Breathing humid air through a tube onto the charred scroll, Young attempted to use an “anatomical blowpipe” instead of “a dissecting knife.” The method was reminiscent of one recalled, years later, by an unnamed fellow at Cambridge who had “once found [Young] blowing smoke through long tubes, and I afterwards saw a representation of the effect in the Transactions of the Royal Society to illustrate one of his papers upon sound.” To keep unfurled leaves apart, Young proposed the use of goldbeater’s skin, the fine coating of a lamb’s intestine used to make gold leaf, following the practice of Antonio Piaggi, a monk, who was the first and most successful unroller of papyri scrolls. When this expedient failed, Young tried “chemical agents of all kinds,” even “maceration for six months in water,” to little avail. He proposed, presciently enough, leaving to the future further work with these fragile relics.

In 1810, two classical scholars, William Drummond and Robert Walpole, published a volume, the Herculanensia, containing “archaeological and philological dissertations” on the papyri and transcriptions of “a manuscript found among the ruins of Herculaneum.” Walpole, a rector in Norfolk, had graduated Cambridge with a prize for a Greek ode; his translation of Greek comic fragments into Latin and English verse appeared in 1805.  Drummond, of course, was the appalled administrator who had berated Hayter years before. 

Drummond had by this time established himself as a classical scholar. In 1805, he published Academical Questions, a controversial plea for ancient philosophy as a prophylactic against dangers presented by modern thought. “Let not those, who would be steady in their opposition to all speculative reasoning, and who would still persevere in imposing new fetters on philosophy, ever tread the soil where the sages of Greece conversed with their disciples,” he opined. Translating the Herculaneum papyri, Drummond hoped to find support for his positions.

Dedicated to the Prince of Wales, the Herculanensia consisted of ten essays or “dissertations” ranging from the population and topography of Herculaneum through discussions of the Greek language, Roman painting, and materials used in writing. Some were written by Drummond, others by Walpole. The eighth, by Drummond, engaged the paleography of the scrolls. The ninth, also by Drummond, provided a discussion, transcription, and emended text of a “manuscript of Herculaneum” that, he claimed, bore the title περι των θεων (On the Gods)—and this was where he hoped to find the evidence he so badly needed.

Drummond maintained that the manuscript represented “the sentiments of an Epicurean, concerning the system of theism professed by the Stoics,” and that it had roused Cicero to write De Natura Deorum (On the Nature of the Gods). Drummond was not concerned with the transcription and emendation per se, for which he declared to have relied on the “Academicians of Portici,” a group that had been working with the papyri in Naples since the 1750s. These, he assumed, were the fragmented manuscript’s emending editors—a curious position since, having employed Hayter and his crew, he had good reason to think otherwise, for Hayter had authored both transcription and emendation. Rather, Drummond was principally interested in finding Epicurean accusations against the Stoics.

To Drummond, then, the scrolls represented an opportunity to pursue his philosophical axe-grinding. To others, the scrolls represented an opportunity to pursue the more modest work of correction and emendation. Charles James Blomfield, a fellow of Trinity College who reviewed the Herculanensia for the Edinburgh Review, was unenthused by the papyri, observing that at  least  one of the manuscripts “is in a very mutilated state; and, from the mode in which it is printed, any attempt to fill it up from conjecture is almost a hopeless task; but, in fact, it does not seem to be worth much trouble; and if all the unedited Papyri contain matter as little interesting as those already published, no good is likely to result from their being given to the world, but an accession to our stock of paleographical knowledge”—and not even that, he continued, “unless future editors will give accurate copies.” Following Drummond, Blomfield attributed the effort to correct parts that could not clearly be read to “the Academicians of Portici” whose labors were “often singularly unhappy, but sometimes successful.” Drummond had only offered “one or two conjectures” of his own, though nothing extensive; neither did he essay a translation.

As Blomfield’s review of the Herculanensia wended into print, Young was writing his own response, a substantial essay of twenty pages, for the Quarterly Review. Buoyed by his firsthand experiences with unrolling papyri scrolls, Young hailed the appearance of the Herculanensia, a “highly interesting volume,” as “a memorable event in the history of classical literature.” He   commended the “profound erudition and extensive knowledge” of Drummond and Walpole, and even quoted at some length Drummond’s account of the scrolls’ history. Brief remarks, also positive, followed concerning the first four dissertations. But the fifth, by Drummond, attracted Young’s criticism. Drummond, he wrote, had been “somewhat precipitate in his conjecture respecting the sense of a passage in the Bacchae of Euripides,” which Young proceeded extensively to correct. He made other “observations” of this sort, his critique escalating until he reached the eighth dissertation, by Walpole, on paleography.

In 1807, Walpole had observed that all but one of the opened scrolls were written in Greek, in capital letters with neither spaces nor accents. Yet Walpole insisted that accents had existed as early as 248 BCE, citing for evidence the orthographic features of a Herculaneum wall inscription and passages from several authors. Young, in contrast, merely recurred to a “usual belief” that accents had been invented a half century later by Aristophanes of Byzantium. This apparently minor orthographic question was of surprisingly profound significance. Its resolution would shape any attempt to restore the text of the fragment, as specialists in paleography knew from long and hard experience.

Debates concerning Greek accents, particularly in ancient poetry, had been ongoing for at least a century and a half. In De poematum cantu et viribus rythmi (1673), the Dutch scholar Isaac Vossius had averred that accents were ignorable late inventions. A half-century later, John Foster, a master at Eton, where the use of accents in teaching Greek was a sine qua non, revived the matter. In a diatribe against Vossius, Foster claimed that orthographic elements such as accents were closely tied to pronunciation and to the anatomical organs of speech. According to Foster, Vossius had failed to consider that “as vocal sounds are formed by organs of speech which are essential and immutable parts of our nature, they must have been in all ages substantially and formally the same, tho’ variously modified in their application.” From this foundation, Foster constructed an argument “drawn from the nature of speech itself” as proof of the early existence of accents.

Young may not have read Foster—there is no evidence that he did—but he would certainly have agreed that inscription necessarily connected to speech. As a student, Young had been interested in phonemes in relation to writing, and he had absorbed the argument, made by the eighteenth-century grammarian Gregory Sharpe, that the earliest writing to capture speech—Hebrew, Sharpe believed—necessarily omitted accents. Although Young might have agreed with Sharpe about that, he had no doubts about the appropriateness of supplying accents to capture the sonic expressiveness of discourse. He even criticized Drummond for “disfiguring” his Greek by omitting them.

Just as Young took exception to Walpole and Drummond’s representation of pronunciation, he also objected to the transcription and translation of the manuscript fragment that appeared in Herculanensia. Because Young held that inscribed meaning depended upon the spatial imprinting of sound in specific ways, it was essential to consider the physical placement of words in the Herculaneum papyri. Young faulted Drummond’s transcriptions for being insufficiently attentive to location, in particular to the blank places where words might once have been. Attending to the spatial character of the scroll, Young proposed a different restitution of the passage. This effort elevated Young’s status as a classical scholar; no longer could he be considered a dilettante. According to his first biographer, Young’s review “at once placed its author, in the estimation of the public, in the first class of the scholars of the age.”

It is not hard to understand why. The differences between the Herculanensia’s fragment and Young’s reconstruction reflect his conviction that, when attempting to determine the meaning of inscriptions of a phonographic language, one must take into account the spatial arrangement of the inscription—and his results were surprisingly accurate.

Though he had not seen Casanova’s original, Young was skeptical of Hayter’s version, which departed from Casanova’s in several respects. Although the original was entirely uppercase and lacked spaces, Hayter had rendered it in lowercase with lacunae. He appended a reconstruction of the text that filled in these empty spaces, substituting words and phrases where Casanova struggled to read the text.

Certain that the sense of the document could only be divined from a reproduction that did not introduce such elements, Young produced “a specimen of the state of the manuscript,” giving “its first page, which is the most defective, as nearly as possible in the form in which we suppose it to stand.”  To restore the physical form of the fragment, Young carefully reworked the Herculanensia text, eliminating spaces and using only uppercase letters. Young’s restoration matches up well with the original apograph—which, again, he had not seen. In line 17, for example, Young eliminated spaces and moved the letters, now uppercase, to the right, precisely as in the (unseen) apograph. To six lines of the Herculanensia version, Young added a letter to make sense of a word. In one amended line (no. 26) Young omitted six letters—των ανο—from the Herculanensia’s transcription. “This line,” Young wrote, “as printed, contains twenty-five letters, and is totally unintelligible.” But, Young continued, by omitting the offending phrase, the sense “may be made to accord perfectly with the context.” Comparing his version to the apograph by Casanova, we find that he has matched the spacing of the apograph correctly.

Not content merely to regenerate the original on which the apograph was based, Young next recreated the entire passage. His notes no longer survive, but they were available to Peacock as he wrote Young’s biography. According to Peacock, Young had worked “an exquisite copy of the entire manuscript— which is now before me—with the lacunae filled up in a differently coloured ink.” This expedient had eventuated in an “intelligible text, which is good Greek,” while allowing “the reader to judge of the propriety and probability of the restorations which are proposed, not only with reference to the space which they occupy, but likewise to the words or portions of words which precede and follow them.”

Young also found grounds for changing the fragment’s title. Instead of the Herculanensia’s περι των θεων (which appeared nowhere in the transcription), Young extracted ΠΕΡΙ ΕΥΣΕΒΕΙΑΣ ΚΑΤ ΕΠΙΚΟΥΡΟΝ from the final four lines, leading him to retitle the passage as “A Treatise on Piety, according to Epicurus.” This result differed completely from Drummond’s, with devastating effects on the latter’s argument concerning Cicero. Having translated the title as “On the Gods,” Drummond was convinced that the fragment had provided Cicero with the fourteenth, fifteenth, and sixteenth chapters of his De Natura Deorum, in which Cicero has Gaius Velleius represent Epicureans. Young demurred, and to prove the point he translated the passage of Cicero to which Drummond referred and listed the supposedly comparable lines. “The reports are not by any means so precisely similar,” he wrote, “as to induce us to suppose, that Cicero had ever undertaken the justifiable liberty of saving himself some little trouble by making use” of another author’s work. This coup de grâce was preceded by a complete translation into English of the re-created passage.

Triumphantly Young concluded: “We are very sorry to observe how lamentably the modern Academicians of Portici,” that is, Hayter, “have fallen short of their predecessors.” In response Hayter sought Drummond’s support. Young’s emendations to the apograph particularly irritated Hayter who, finding them entirely faulty, told Drummond that “the supposed facsimile of the Reviewer is not a facsimile of the original, neither in the distances, nor in the form of the characters.” Hayter may have claimed as much, but we have already seen that, “facsimile” or not, Young’s proposed revision of the transcription does fairly well match the original.

Because Young’s critique implicitly tarnished the diligence and competence of the apograph’s transcriber, Hayter devoted much of his reply to insisting that his dimensions for the lacunae were accurate. Not only had they been “taken with much care by the copyist,” but Hayter had also personally checked them against the original. He insisted that his own “conjectural letters” took account of potential sources of copying errors, and perhaps he had—though Young’s point was not that the Herculanensia’s transcription added too many letters for the extant spacing, but that it made little sense. Finally, Hayter claimed that, unlike his own reconstitution, Young’s emendations did not fit the apograph. In Young’s original “facsimile”—or a copy of it, obtained perhaps from Young himself—Hayter spied an apparent inconsistency with Young’s printed revision. In the ninth line of his reconstruction of the apograph, Young gave ΔωΡΕΑΝ, “free,” for Hayter’s lowercase δορεαν, whereas in Young’s proposed reconstitution, the word ΜωρΙαν, “folly,” appears instead. The apograph’s ninth line does seem to contain a Δ, but the letter, being broken, was hard to read. Young had substituted “folly” because the latter, which made sense in context, justified his emendation of a character that Casanova may well have mistaken. Hayter nevertheless fastened on this anomaly as evidence of Young’s incompetence.

With this foray into the words and inscriptions of antiquity, Young revived his longstanding interest in languages, their origins, and the ways in which their sounds could be visually represented; in this way, his immersion in the Herculaneum papyri prepared him for his confrontation with the scripts of ancient Egypt. His adversary, Hayter, did not benefit nearly as much. Printed privately, Hayter’s response seems to have had little effect, perhaps because he had unwisely included Drummond’s letter of rather lukewarm support with the publication. That Young’s review was published anonymously may have reduced any pressure he felt to reply, which he did not. The damage, at any rate, had been done. Four decades later, Peacock noted that “no subsequent attempt was made to re-establish the character of Mr. Hayter as a scholar, or to vindicate his conduct with respect to the abandonment of the papyri and of the copies made of them.”
