Ancient Khmer City of Koh Ker was occupied for centuries longer than previously thought

PLOS—The classic account of the ancient city of Koh Ker is one of a briefly-occupied and abruptly-abandoned region, but in reality, the area may have been occupied for several centuries beyond what is traditionally acknowledged, according to a study published October 10, 2018 in the open-access journal PLOS ONE by Tegan Hall of the University of Sydney, Australia and colleagues.

Koh Ker was part of the Khmer kingdom during the Angkor period in what is now Cambodia. For a mere two decades in the tenth century CE, the city served as royal capital, and it has long been proposed that after the royal seat moved back to Angkor, the city and its surroundings were abandoned. In this study, Hall and colleagues tested this theory by analyzing charcoal and pollen remains in sediment cores spanning several centuries in three Koh Ker localities, including the moat of the main central temple. From these data, they inferred a long history of fluctuations in fire regimes and vegetation which are highly indicative of patterns of human occupation and land use over time.

The newly-painted picture is of a region that was occupied well before the Angkor period, at least as far back as the late 7th century CE, and continuing seven centuries or more after the royal seat’s departure. The authors suggest that the mobility of royal houses may have had less of an impact on regional populations in the Khmer kingdom than previously thought. This study also highlights the utility of palaeoecological tools to reconstruct the occupational history of ancient urban settlements.

Hall adds: “When the environmental record is analyzed, it becomes clear that Koh Ker was much more than a temporary 10th century capital of the Khmer kingdom. The settlement history of the site is extensive and complex, beginning in the pre-Angkor period and lasting for centuries beyond the decline of Angkor.”

The Golden Rhinoceros

The waters of the Shashe River join those of the Limpopo close to where the borders of South Africa, Botswana, and Zimbabwe converge. Nearby, on the right bank (on South African territory) sits the Greefswald farm. It is the property of the Republic of South Africa, and its cultural landscape” has been inscribed on UNESCO’s World Heritage List. As for the natural landscape, it is high savanna, home to the thorn tree and mopane, covered with grass in the rainy season and dotted here and there with enormous baobab trees. Mapungubwe, the “hill of the jackals” in Venda (a language of southern Africa), is a steepsided sandstone outcrop that gives its name to a collection of archaeological sites in the vicinity dating from the tenth to the thirteenth century. During apartheid, this site was one of the battlefields over the country’s past (the skirmishes were fought among white academics, it goes without saying): was it possible, the whites asked, that black Bantus were responsible for Mapungubwe, or was it necessary to invoke some other population with a more noble pedigree? Was it possible that the Africans who had lived and prospered here were the ancestors of the black South Africans then confined to Bantustans, or “reserves, and townships? Was it possible that civilized natives had preceded white colonists on ground where the latter believed, or gave the impression of believing, that they were the first occupants?

As befits a place that is today considered the “capital” of the first South African kingdom, the objects discovered there have become the country’s “crown jewels,” and the history of their transmission to our own time, an archive. From the moment of its discovery, a story developed that gave prominence to white heroes—as could only be expected of a site for which the colonial elite was both the discoverer and the exegete—just as elsewhere colonial settlers and Western readers were fond of a white queen of the Atlanteans. As is often the case when lieux de mémoire are at stake, this intrigue transformed a banal story of pillage into an allegory that romanticizes the circumstances of the objects’ discovery.

It is therefore a story of mystery and friendship, which perhaps really happened in the way it’s been told, but is no less mythical for it. In his youth, Francois Bernhard Lotrie had served as guide to missionary and explorer David Livingstone; he had been a gold prospector and elephant hunter. At the beginning of the twentieth century (he died in 1917), Lotrie settled in the Soutpansberg massif not far from Limpopo. Here, we are told, the eccentric, solitary old man gave an African friend, Mowena, an ancient piece of terra-cotta pottery. It was said that he had taken treasures from a sacred hill he had discovered. Around 1930, a group of young men went for a weekend hunt in this same region. Of course, they were whites, for only whites could freely cross the property of other whites. While looking for water, they came across an old man, an African, who diligently and respectfully offered them refreshment. The old man was Mowena. One of his young guests, Jerry Van Graan, a student of history at Pretoria, was intrigued by the vessel to which he put his lips: the celebrated terra-cotta. Returning in December 1932 with a group of his friends, he managed to identify and climb the hill on the Greefswald farm. There they discovered tombs, and they spent days disturbing them, laying hands on a small rhinoceros made of gold foil. Completed much later from scattered data, the retrospective inventory of three disturbed tombs (out of around thirty) reveals that they were shallow graves, perhaps surmounted by stone slabs, where the dead were buried in a sitting position, unless the skeletal remains had initially been buried elsewhere before being reburied there. The graves contained several golden animals, the gold casing of a “scepter” or a cane as well as a headrest, gold filigree jewelry, thousands of gold beads, tens of thousands of glass beads, and both intact and broken pottery.

Seized with misgivings, the young man would later write to Leo Fouché, his former history professor, to inform him of his discovery. Fouché, a liberal Afrikaner, immediately had the farm bought by the state, purchased objects coming from the site that had not already been dispersed or melted down, and launched the first excavation campaign. It was learned that other clandestine visitors had climbed the hill during the 1920s. Since then numerous structures have been excavated, a remarkable series of objects have been discovered, but of course information we would like to have about the disturbed graves themselves is lost forever. The golden rhinoceros is nothing more than a recovered stolen document, except that a stolen archaeological artifact will always remain lost—even if it is rediscovered: it will always be missing the associations its original context would have allowed us to observe.

The archaeological research carried out over several decades at Greefswald has revealed stratigraphic deposits several meters thick, not only at the top of the hill but also at its base, as well as at several other sites within a radius of a few dozen kilometers from the hill. The sequence of occupation illustrates an increase in population size and social differentiation between the tenth and the thirteenth century. Social differentiation is especially noticeable toward the summit of Mapungubwe, an area occupied by a new elite from the end of the twelfth century, and toward the upper end of the stratigraphic deposit, corresponding to the last occupations a little before 1300, when high-ranking individuals had themselves buried there with their wealth, thereby denying it to the living. But can we refer to them as kings without presupposing the nature of a political formation we can apprehend only very imperfectly through the prism of archaeology? Let’s stick with kings, if the golden objects are to be taken as royal symbols or evidence of royal status, but only if we don’t forget the other dimensions of the society the archaeological data shed light on. Here medieval societies were distinctly pastoral. At the excavated sites, domestic spaces were spread out around a vast central corral, a sign of the important place cattle occupied not only in the economy and diet, but also, more generally, in all social transactions, notably matrimonial ones, as was the case in the societies of southern Africa in later centuries. The numerous clay animal figurines, particularly of cows, that come from this region further reinforce this point.

To better grasp Mapungubwe’s significance, we must zoom out to measure the regional synchronies while also honing in on the elements of material culture. That the rise of the sites on the right bank of the Limpopo is linked in one way or another to the development of mining on the plateau on the other bank, in current-day Zimbabwe, is very probable, partly because, as far as we know, gold was not exploited on the South African side until the colonial era. That strong social distinctions and spectacular evidence of the accumulation of gold begin to appear in this fluvial region at exactly the same time as the oldest mentions of a gold trade with the south coast of East Africa is equally remarkable. A triangular relationship thus took shape about which we can be even more precise. The minute glass beads, found in the thousands during the excavation, likely originated in Arikamedu, near Pondicherry, in southeast India, unless they came from another atelier in the Indo-Pacific” production zone. Like the cowries from the Maldives, or the fragments of Song dynasty greenware, celadon,” these beads bear witness to the trade nourished by the commercial zone of the Indian Ocean. In exchange, did the little “kingdom” of Mapungubwe export elephant ivory (we have found bracelets whose standardized form and technique suggest serial production); the skins of cats and other carnivores, if we are to judge by the bones of genets, civets, leopards, servals, and lions that show signs of cut marks, and which have nothing to do with food waste; and gold? Perhaps, although only gold objects (beads, jewelry, objects finished with gold leaf) have been uncovered, not ingots, which would soon have been melted down. But it’s not necessary: Magpungubwe Hill could have traded in several directions with its new regional partners without necessarily being their intermediary. It could have profited from this trade by amassing a treasure out of goods that the other regional partners bought or sold for their weight value. Symbolically, a golden rhinoceros was something more than a gold nugget or a dinar.

The little rhinoceros is perhaps, in its way, evidence of the existence of a network of contacts even more complex. Reassembled, then restored, the object measures a little more than fifteen centimeters long. It is solid in appearance; the neck looks more “robust” than that of the real animal. But its compact appearance, the projection of its shoulder line, and its lowered head reinforce the feeling of power that emanates from the figurine. Lines of small, regular perforations indicate that the hammered foil was riveted to a wooden core, which is corroborated by the gold pins found during the sieving of the sediment from the graves. The animal’s tail is a thin, solid gold cylinder, the ears delicately cut out-turned ovals, the eyes two small half-globular “upholstery nails,” the horn a gold foil cone. The horn? It has long been pointed out that unlike the African rhinoceros, which has two horns, the golden rhinoceros of Mapungubwe has only one. Its excavators, custodians, and restorers were categorical on this point: it had never had a second horn. We can see here a simple stylistic feature or the representation of an Asian species, the Indian rhinoceros (Rhinoceros unicornis) or the Javan rhinoceros (Rhinoceros sondaicus), both of which have a single horn. For this reason, some scholars have considered the rhinoceros, emblematic of the site and the history of South Africa as a whole, an imported object. That is unlikely for its golden carapace; studies done on the geochemical fingerprint of the metal from several gold objects found at Mapungubwe point to a regional provenance. But it re- mains a possibility for the object’s missing part: its core, certainly made of wood, which began to slowly disintegrate as soon as it was buried. Only a meticulous excavation could have yielded fibers whose analysis might have revealed its species and age.

We will thus stick with the hypothesis that the wooden figurine was perhaps made elsewhere than Africa, and was gilded on the banks of the Limpopo as a sign of its appropriation by royalty. At any rate, this hypothesis is not even necessary if one simply wants to illustrate the emergence of a power capable of harnessing the political benefits of a commercial relationship with unknown worlds. For Mapungubwe, with its society based on a traditional agricultural economy, was situated both beyond the horizon of regular Islamic trade—probably even beyond the limits of the land known to the coastal African merchants—and at a good distance from the goldfields of the Zimbabwean plateau.

Bibliographical Note

Th Order of Mapungubwe, established in 2002, is the highest distinction awarded by the Republic of South Africa; its insignia incorporates the golden rhinoceros. The account of the site’s discovery is taken from Sian Tiley, Mapungubwe: South Africa’s Crown Jewels (Cape- town: Sunbird Publishing, 2004), which catalogs the objects kept in the museum dedicated to Mapungubwe at the University of Pretoria. The original excavations by Leo Fouché were published in Mapungubwe, Ancient Bantu Civilization on the Limpopo (Cambridge: Cam- bridge University Press, 1937). The Mapungubwe Cultural Landscape was added to the list of World Heritage sites in 2003. For a presentation of the site as a “cultural landscape,” see Jane Carruthers, “Mapungubwe: An Historical and Contemporary Analysis of a World Heritage Cultural Landscape,” Koedoe 49 (2006): 1–13. Andrie Meyer, “K2 and Mapungubwe,” South African Archaeological Society Goodwin Series 8 (2000): 4–13, delivers an excellent synthesis of the stratigraphic sequence. For a retrospective inventory of the tombs’ contents and an updating of the anthropological data based on unpublished photographs, see Maryna Steyn, “The Mapungubwe Gold Graves Revisited,” South African Archaeological Bulletin 186 (2007): 140–146. Some samples of gold from Mapungubwe have undergone a spectrometric analysis; see B. Grigorova, W. Smith, K. Stülpner, J. A. Tumilty, and D. Miller, “Fingerprinting of Gold Artefacts from Mapungubwe, Bosutswe and Thulamela,” Gold Bulletin 31 (1998): 99–102. Linda C. Prinsloo, Nigel Wood, Maggi Loubser, Sabine M. C.

Finally, a study of glass beads has recently been done by Marilee Wood, “Making Connections: Relationships between International Trade and Glass Beads from the Shashe-Limpopo Area,” South African Archaeological Society Goodwin Series 8 (2000): 78–90, from which is borrowed the hypothesis of an Indo-Pacific origin. The animal data come from Elizabeth A. Voigt, Mapungubwe: An Archaeozoological Interpretation of an Iron Age Community (Pretoria: Transvaal Museum, 1983). Two new gold foil figurines— one a humpbacked bovine, the other a cat—were reassembled from fragments in 2009 and are on display in the Mapungubwe Museum in Pretoria.

Th University of Pretoria has published a compendium of numerous documents relating to the history and institutional environment of the excavations at Mapungubwe: S. Tiley-Nel (ed.), Mapungubwe Remembered: Contributions to Mapungubwe by the University of Pretoria (Pretoria, 2011). Among the reproductions of important documents are Van Graan’s letter to Fouché and the transcript of an interview in which the aged Van Graan recounted the circumstances of the discovery.

From the birth of Islam in the seventh century to the voyages of European exploration in the fifteenth, Africa was at the center of a vibrant exchange of goods and ideas. It was an African golden age in which places like Ghana, Nubia, and Zimbabwe became the crossroads of civilizations, and where African royals, thinkers, and artists played celebrated roles in the globalized world of the Middle Ages. The Golden Rhinoceros brings this unsung era marvelously to life, taking readers from the Sahara and the Nile River Valley to the Ethiopian highlands and southern Africa.

Drawing on fragmented written sources as well as his many years of experience as an archaeologist, François-Xavier Fauvelle painstakingly reconstructs an African past that is too often denied its place in history—but no longer. He looks at ruined cities found in the mangrove, exquisite pieces of art, rare artifacts like the golden rhinoceros of Mapungubwe, ancient maps, and accounts left by geographers and travelers—remarkable discoveries that shed critical light on political and architectural achievements, trade, religious beliefs, diplomatic episodes, and individual lives.

François-Xavier Fauvelle is senior fellow at the National Center for Scientific Research (CNRS) in Toulouse, France, and one of the world’s leading historians of ancient Africa. The author and editor of numerous books, he has conducted archaeological digs in South Africa, Ethiopia, and Morocco.

Straws that Bind

William (Brad) Hafford is an archaeologist who received his Ph.D. from the University of Pennsylvania and is a Research Associate at the Penn Museum. He has excavated in many places around the world including Greece, Egypt, Syria and Iraq. His primary research involves ancient economics, such as the development and expansion of ancient trade networks. Increasingly, he is interested in how early trade and interaction contributed to the development of complex urban society itself.

Kwayes?” Isma’ein says as he folds the woven tube and waves it in my direction. “Good. Very good.” Smoke billows from between his teeth, yellowed from tobacco. His weathered face radiates from genuine happiness and he chuckles as he taps the woven fold against my arm. It’s clear he wants me to take it and follow his lead in drawing smoke from the water pipe at the end of the snaking cloth tube. I nod, take the single fold out to its length and hesitate a moment. The others seated on the mats and leaning against the pillows in the mud brick hut stare expectantly, curiosity in their expressive features. It’s anticipation there, something about accepting convention, whether this ajnubi can accept local life. It’s a connection to tradition and to community. By joining in, I would be one step closer to them. I breathe in through the tube. The coals at the top of the nargileh glow brightly. Bubbles form in the jar below as smoke from the apple-flavored tobacco filters through the water. It’s almost as fascinating as the people around it.

I’m no smoker and smoking itself is no longer popularly acceptable in western culture, but in the east it holds on in some ways. In the large, cosmopolitan cities like Cairo or Istanbul, smoking a nargileh (called a hookah in some areas) still happens but typically on a more individual level. You can order one in restaurants or go to dedicated smoking bars and receive your own pipe with an individual plastic mouth piece in a sealed wrapper. But in the smaller towns and villages people often gather around one pipe and share, handing the hose around the circle, always passing to the right. It’s semi-ritualized, a way to relax, chat, and bond.

I cough. Isma’ein laughs and slaps my shoulder. Others make motions that show I should try again. We don’t really share a language but we are sharing an experience.

As a Near Eastern archaeologist I have now been to the region countless times, but this was my first trip more than 20 years ago. I was seven hours overland travel outside of Damascus and I had yet to learn any Arabic. But already I was connecting with the people who would help me accomplish my archaeological goals. And I was acquiring my first words in a rather local dialect. Kwayes is colloquial for “good” and ajnubi is “foreigner.”

Of course there were a few other English-speaking archaeologists there and they helped me adjust to the rural Syrian world, but the impact of the seemingly ceremonial introduction to the locals through sweet-smelling tobacco smoke still resonates with me today. The world, including the Middle East, is increasingly aware of the health problems inherent in smoking and perhaps this tradition is beginning to fade even in the smaller places, but the key in the episode for me was in the social gathering itself. Such gatherings are integral to the cohesion of society and they center on a shared activity. The most common activity in all cultures is eating and drinking—and the verb used colloquially for smoking in this area of northern Syria, bishrab, actually means ‘to drink.’

So as we drank in the smoke together, we were becoming closer—displaying trust and a willingness to accept each other as colleagues. Similar social gatherings, on small and large scales and with varying accoutrement, have been connecting people for millennia.

Recent discussions of banning drinking straws have brought this episode back to my mind. It may seem a bit of a leap from ‘drinking’ smoke with the Chafrat tribe in northeastern Syria twenty years ago to banning plastic straws today, but the idea stems from the feeling of ceremony and the evidence that early straws promoted the same kind of bonding experience I had shared with Isma’ein and his people.

Ur and the Drinking Straw

The Penn Museum, where I work, has some of the earliest drinking straws ever uncovered. These examples are 4,500 years old and come from the ancient city of Ur. I’ve been studying this city on the southern reaches of the Euphrates River in Iraq for about 15 years. In 1922 the Penn museum, jointly with the British Museum, began a major excavation there. Some of the artifacts and most of the records of the dig now reside in Philadelphia and London. The excavations lasted for 12 years and during this time the director, C. Leonard Woolley, uncovered some of the most famous Mesopotamian artifacts ever found. Many of them came from the Royal Cemetery.

There were more than 1,800 graves in the Royal Cemetery but only 16 garnered the moniker ‘royal.’ These were typically the largest, with built tomb chambers, accompanying burials of attendants, and many luxury objects. Several included drinking straws, but not the sort we think of today. The most complete was four and half feet long and made of gold. Others were copper and covered with lapis lazuli. They were clearly for display as well as for use.

Were they just luxuries, kings and queens showing off by sipping their fancy drinks through golden tubes while the masses could only look on in envy? It would be easy to think so given the circumstances of their find and the way we tend to use straws today, in a rather individual way, keeping our drinks to ourselves. But I would suggest they show almost the opposite, or rather that they developed out of a tradition of sharing that brought people together and slowly led to hierarchical structures that meant the wealthy could and did show off with their straws and other possessions.

But how do we know these long tubes in the royal graves really were drinking straws? In this period of Mesopotamian history we have something of a perfect storm of evidence. We have the tubes themselves, buried with their owners often with one end still inside a large jar, but we also have depictions of people drinking from large jars through long tubes. These depictions typically appear on cylinder seals, cylindrical stones with carved images that were rolled across clay tablets to leave an impression—a kind of authorization or signature. The banquet scene showing people drinking with long straws is relatively common on seals of the third millennium BCE, and there is some evidence of it in seal impressions a thousand years earlier. It typically shows two people flanking a large jar, each with a curved tube to their lips and the other end inside the jar. Two or three more straws are often depicted emerging from the same jar. This surely indicates other people sharing the liquid, but the seal carver could only show two given the medium of a small stone.

Originally, the straws were nothing more than reeds. Ur was founded in a marsh some 7,500 years ago and so reeds were very common. They were used for many things, including baskets, mats, roofing material, and even for building houses. As the marshes receded and the head of the Persian Gulf silted up and pushed farther to the south, the inhabitants of Ur dug canals to their fields and the population grew. In the fourth millennium BCE, socio-political changes were on the rise—the land needed increasing irrigation and the state was forming. As societies grow beyond groups of extended family, they require something larger than the bonds of blood to keep them together. In order for a society to function, people must accept one another, unifying under some metaphorical banner. This process is benefited, perhaps begun, by ceremony and feasting.

___________________________________

This seal, belonging to a man named Lugal-sasir (as inscribed on the seal in cuneiform), shows two standing men drinking from a jar using long straws. Next to them is a man fighting a bull and another fighting a lion. If read as different episodes of one story, perhaps the two men drinking are the same men sharing after successfully subduing the beasts.

___________________________________

Many theories today point to the importance of feasting in early large-scale communities and the potential for these gatherings to lead to still larger groups through the bonds of friendship and socialization. Religion often establishes the bond, partially by sponsoring—or providing the backdrop for—feasting and ceremony. The early ‘temple’ at Gobekli-tepe in Turkey may point to this very process at an early period where small hunting and gathering groups likely met and formed a more permanent place for annual feasts. This would allow them to increase their gene pools by finding spouses outside their groups and could lead to larger social units as well as more sedentary lifestyles.

Similarly, in Mesopotamia in the Uruk period of the fourth millennium and well before, people were gathering in larger and larger groups to share in crops, materials, skills, and ideas, essentially sipping the stuff of civilization. At these gatherings they may have made large jars of liquid, perhaps beer, and drunk together from the same pot by using long reeds. Unlike our small individual straws that, when made of plastic, are now threatening our environment, these long natural straws promoted sharing—many people gathered around one jar, discussing and drinking together.

________________________________

As social groups grew larger, hierarchies established themselves and with the rise of kingship and administration to oversee larger group activities like growing enormous amounts of grain to feed the citizenry and weaving huge amounts of cloth to clothe them, the division of wealth also widened. The straws that have been preserved in the archaeological record are those that had been wrapped in gold foil, or made of hammered copper tubes sealed with bitumen and decorated with lapis lazuli. The few luxury straws found in the royal tombs might be the tip of a proverbial iceberg, the visible correlate of perishable reed straws that were in much more common use.

This is not a plea for the straw any more than it is a plea for smoking. Instead, it is an observation on the sharing aspects of any feast or social gathering that even today helps us to bond and see each other in a common light.

When I worked in Greece, each season the entire town came together for a glendi (party) where excavators and locals ate, drank and danced together. In Egypt we went to colleagues’ houses and ate until we simply couldn’t eat any more. I now work in Iraq and there we hold an end-of-season feast with the local village where we all share in food and music. These gatherings help us to connect and stay connected. Similarly, gatherings of peoples in the past likely helped lead to the social organizations of cities and civilization as we know it.

Easter Island inhabitants collected freshwater from the ocean’s edge in order to survive

BINGHAMTON UNIVERSITY, BINGHAMTON, N.Y. —Ancient inhabitants of Rapa Nui (Easter Island) maintained a society of thousands by utilizing coastal groundwater discharge as their main source of “freshwater,” according to new research from a team of archaeologists including faculty at Binghamton University, State University at New York.

The team, which included Binghamton University Professor of Anthropology Carl Lipo, measured the salinity of coastal water around the island of Rapa Nui, in order to determine whether or not the water close to the shores had a salt concentration low enough for humans to safely drink.

The process of coastal groundwater discharge makes it possible for humans to collect drinkable freshwater directly where it emerges at the coast of the island.

By measuring the percentage of salt in the coastal waters, and finding it safe for human consumption, and by eliminating other options as primary sources of drinking water, the researchers concluded that groundwater discharge was a critical factor in the sustenance of the large population the island is thought to have harbored.

“The porous volcanic soils quickly absorb rain, resulting in a lack of streams and rivers,” Lipo said. “Fortunately, water beneath the ground flows downhill and ultimately exits the ground directly at the point at which the porous subterranean rock meets the ocean. When tides are low, this results in the flow of freshwater directly into the sea. Humans can thus take advantage of these sources of freshwater by capturing the water at these points.”

Lipo said the freshwater mixes with the saltwater slightly, creating what’s called brackish water, but not enough for the water to contain harmful levels of salt to human consumers. It does, however, mean that the islanders rarely used salt on their foods, because the water they drank contributed so drastically to their daily salt intake.

Lipo’s team indicated researchers have often wondered why the island’s famous statues are only located in certain places around the island, with a high concentration of them near the coasts.

“Now that we know more about the location of freshwater, however, the location of these monuments and other features makes tremendous sense: they are positioned where freshwater is immediately available,” Lipo said.

He said there are very few sources of freshwater on the island, including two lakes that are perilously difficult to access, no streams, and one spring that is often reduced to a wetland bog. Much of the opposition to the research of Lipo’s team is the presence of taheta on the island, which are small, carved-out cisterns used for collecting rainfall. To refute this argument, Lipo’s team explained that if collecting rainwater was extremely necessary to island survival, the cisterns would be much larger, instead of being able to hold only between two and four liters of water each.

The team’s research shows that the little amount of rainfall that Rapa Nui receives (1240 mm/yr), coupled with the basic evaporation rate of water in a climate such as the island’s, means that on average, taheta could not be used as viable sources of drinking water 317 days out of the year.

This led the researchers to conclude that there must be a different source of drinking water, in order for a population numbering in the thousands to sustain itself. European accounts of first encounters with the island in the 18th century include passages where the natives appear to simply drink seawater. Since the human body cannot process the high salt concentration of seawater, this supports the team’s groundwater discharge theory.

Lipo said the group’s next project is to try to understand how closely the availability of freshwater in certain locations is linked to the methods and means of building the large statues on the island. He is hopeful that this research will benefit both science and the modern world.

“This information ultimately sheds light on the conditions that drove and enabled these communities to work together to achieve their feats of engineering,” Lipo said. “By gaining knowledge about community scale behavior, we can gain insights into the general conditions necessary for group-level cooperation—whether in the past or in contemporary society.”

Dryer, less predictable environment may have spurred human evolution

UNIVERSITY OF ARIZONA—A progressively drying climate punctuated by variable wetter episodes may have precipitated the transition from our hominin ancestors to anatomically modern humans, according to research published on Oct. 8 in the online edition of the Proceedings of the National Academy of Science (PNAS).

Since the discovery of a rich assemblage of human fossils as well as stone tools and other archeological evidence in the rift valley of East Africa, a region often referred to as the cradle of humanity, scientists have attempted to piece together the complex puzzle that is the history of our human origins, including the environmental context of that history.

The study, based on lake sediment cores, is the first to provide a continuous environmental context for the diverse archeological evidence recovered from nearby localities in the rift valley basins of southern Kenya. The cores were sampled from Lake Magadi as part of the Hominin Sites and Paleolakes Drilling Project, or HSPDP, which is directed by University of Arizona professor Andrew Cohen.

Lake Magadi, a shallow, periodically dry lake, is close to the Olorgesailie basin in Kenya, one of the most productive sites for archaeological evidence of human evolution in Africa. The authors suggest that the profound climatic changes may have been driving forces behind hominin evolution, the origins of modern Homo sapiens and the onset of the Middle Stone Age.

While previous hypotheses have related hominin evolution to climate change, most prior studies lack regional-scale evidence for a link between environment and hominin evolution, the authors write in the paper, “Progressive aridification in East Africa over the last half million years and implications for human evolution.” According to the study, a trend toward intense aridification in the area began 575,000 years ago. The change, not previously documented in continuous continental cores from East Africa, corresponds with faunal extinctions and a major transformation in stone tool technology documented in the Olorgesailie region.

“Much evidence for human evolution has been gathered from the area, but linking those records to detailed environmental records was missing until now,” said the study’s lead author, Richard Owen, of Hong Kong Baptist University. “There is a big gap in the records between the last Early Stone Age tools 500,000 years ago and the appearance of Middle Stone Age tools about 320,000 years ago. Our results plugged that gap with a continuous environmental record.”

A critical transition occurred sometime during this gap, a period for which archeologists have unearthed evidence of a leap in early humans’ abilities to make, use and trade stone tools.

The cores from Lake Magadi provide the first detailed link between climate change and events known from the region’s archeological record.

“We have known for a while that the climate at the time was very varied, but the key here is that the records are in proximity to the archeological evidence for this transition,” says Cohen, a professor in the University of Arizona’s Department of Geosciences. “The older stone tools found at Olorgesailie did not change much between 1.2 million and a half-million years ago. And suddenly, after 500,000 and before 320,000 years ago – we don’t know exactly when, but in that timespan – there was a critical transition in archeology when tools became more sophisticated and were transported over longer distances.”

At the same time the lake core records point to the climate becoming drier and more variable, there is evidence elsewhere in Africa of the appearance of modern Homo sapiens, prompting much speculation whether the two are connected, Cohen said.

“Whether the evolution of bigger brains goes hand in hand with new toolkits is not entirely clear,” he said. “But the earliest modern Homo sapiens fossils from Morocco date back 325,000 years, the same time we see this transition of tools. And both happened around the same time that our core record indicates severe drying very close to the archeological sites.”

The deepest core drilled at Lake Magadi reached 200 meters (650 feet), penetrating all sedimentary layers down to the volcanic bedrock of the lake. The core samples, each about 10 feet long and 2 1/2 inches in diameter, are cut into manageable 5-foot segments, packaged and air-freighted to the National Lake Core Facility at the University of Minnesota for curation, analysis and storage.

According to the hypothesis of variability selection, a rapidly changing environment creates selective pressure that forces species to adapt to rapid change, Owen said. Under that scenario, the larger brains of anatomically modern humans would have allowed our ancestors to adapt quickly to an increasingly less predictable world.

“Now we have evidence that at the same time the toolkits were changing, the mammal fauna changed and the climate became more arid,” Owen said. “So you have a series of coincidences that makes you think, ‘This could be real.’ Now we can say when the environment changed and then compare that to the archeological evidence of the region.”

Drilling at other nearby sites by HSPDP has been completed as researchers gather more of the region’s climate data to continue studying the importance of environmental variability in the course of human evolution.

Neanderthal healthcare practices crucial to survival

UNIVERSITY OF YORK—Research at the University of York has suggested that Neanderthals embraced healthcare practices, such as assisting in cases of serious injury and the challenges of childbirth.

Healthcare practices in this period of human evolution have often been studied alongside complex cultural behavior, mostly based around research into rituals and symbols associated with death. This new study, however, sets out, for the first time, that healthcare could have had a more strategic role in Neanderthal survival.

Previous research at the University of York has already suggested that compassion and caring for the injured and dying could have been a factor in the development of healthcare practices, but further investigation has now shown that there was evolutionary drivers behind it too.

Researchers investigated the skeletal remains of more than 30 individuals where minor and serious injuries were evident, but did not lead to loss of life. The samples displayed several episodes of injury and recovery, suggesting that Neanderthals must have had a well-developed system of care in order to survive.

Dr Penny Spikins, from the University of York’s Department of Archaeology, said: “Neanderthals faced multiple threats to their lives, particularly from large and dangerous animals, but in popular culture Neanderthals have such a brutish and strong image that we haven’t really thought too deeply about their vulnerabilities before now.

“We have evidence of healthcare dating back 1.6 million years ago, but we think it probably goes further back than this. We wanted to investigate whether healthcare in Neanderthals was more than a cultural practice; was it something they just did or was it more fundamental to their strategies for survival?

“The high level of injury and recovery from serious conditions, such as a broken leg, suggests that others must have collaborated in their care and helped not only to ease pain, but to fight for their survival in such a way that they could regain health and actively participate in the group again.”

It is generally accepted that more than 80% of the skeletal remains known to archaeologists display several injuries, some of which may have required simple remedies, such as food and rest, and others that would have required serious levels of care due to a high risk to life.

Neanderthals lived in small groups, so any one loss of life was particularly significant to the survival of the whole community. Injury, over disease, was the most common threat, as Neanderthals didn’t live in the type of environment, or in large enough communities, to be at high risk from pathogens.

Neanderthal women, however, were at risk from difficulties in childbirth. The shape of their pelvis and the size and shape of a child’s head was similar to that of modern-day humans, so it is assumed that they would also have encountered some common issues in childbirth.

Dr Spikins said: “It is likely that they would have had assisted childbirth; the role that we now attribute to midwives. Without support, they probably could not have survived the toll that the death rate of mothers and babies could have taken on their communities.

“When we look at the daily risks and dangers involved in hunting and finding food, as well as in childbirth in respect to their small hunting communities, it is not surprising that they would develop practices to improve health and reduce mortality risk.

“We can start to see healthcare as a pattern of evolutionary significant collaborative behavior, alongside hunting together, food sharing and parenting. In this we can see why providing healthcare to those in need today is such an important part of human life.”

Researchers now aim to expand this work to look at potential methods of healthcare and how far back healthcare practices can be traced.

Modern humans inherited viral defenses from Neanderthals

STANFORD UNIVERSITY—SCHOOL OF HUMANITIES AND SCIENCES—Neanderthals mysteriously disappeared about 40,000 years ago, but before vanishing they interbred with another human species that was just beginning its global spread. As a result of these ancient trysts, many modern Europeans and Asians today harbor about 2 percent of Neanderthal DNA in their genomes.

Curiously, some snippets of Neanderthal DNA pop up more often in modern human populations than others, leading scientists to wonder if their spread was propelled by chance or whether these frequently occurring genes confer some functional advantage.

Stanford scientists have now found compelling evidence for the latter. “Our research shows that a substantial number of frequently occurring Neanderthal DNA snippets were adaptive for a very cool reason,” said Dmitri Petrov, an evolutionary biologist at Stanford’s School of Humanities and Sciences. “Neanderthal genes likely gave us some protection against viruses that our ancestors encountered when they left Africa.”

When first contact occurred between the two species, Neanderthals had been living outside of Africa for hundreds of thousands of years, giving their immune systems ample time to evolve defenses against infectious viruses in Europe and Asia. Our newly emigrated ancestors, by comparison, would have been much more vulnerable. “It made much more sense for modern humans to just borrow the already adapted genetic defenses from Neanderthals rather than waiting for their own adaptive mutations to develop, which would have taken much more time,” said David Enard, a former postdoctoral fellow in Petrov’s lab.

Petrov and Enard said their findings are consistent with a “poison-antidote” model of gene swapping between two species. In this scenario, Neanderthals bequeathed to modern humans not only infectious viruses but also the genetic tools to combat the invaders.

“Modern humans and Neanderthals are so closely related that it really wasn’t much of a genetic barrier for these viruses to jump,” said Enard, who is now an assistant professor at the University of Arizona. “But that closeness also meant that Neanderthals could pass on protections against those viruses to us.”

In their new study, published online Oct. 4 in the journal Cell, the scientists show that the genetic defenses that Neanderthals passed to us were against RNA viruses, which encode their genes with RNA, a molecule that’s chemically similar to DNA.

Persistent genes

The scientists reached their conclusions after compiling a list of more than 4,500 genes in modern humans that are known to interact in some way with viruses. Enard then checked his list against a database of sequenced Neanderthal DNA and identified 152 fragments of those genes from modern humans that were also present in Neanderthals.

The scientists showed that in modern humans, the 152 genes we inherited from Neanderthals interact with modern day HIV, influenza A and hepatitis C – all types of RNA virus. From this, Enard and Petrov concluded that these genes helped our ancestors fend off ancient RNA viruses that they encountered upon leaving Africa.

Interestingly, the Neanderthal genes they identified are present only in modern Europeans, suggesting that different viruses influenced genetic swapping between Neanderthals and the ancient ancestors of today’s Asians. This makes sense, Enard said, since interbreeding between Neanderthals and modern humans is thought to have occurred multiple times and in multiple locales throughout prehistory, and different viruses were likely involved in each instance.

In addition to offering a new perspective on interbreeding between Neanderthals and humans, the new findings also demonstrate that it’s possible to comb through a species’ genome and find evidence of ancient diseases that once afflicted it – even when the viruses responsible for those diseases are long gone. This technique would work especially well for RNA viruses, whose RNA-based genomes are more frail than their DNA counterparts, Enard says.

“It’s similar to paleontology,” he added. “You can find hints of dinosaurs in different ways. Sometimes you’ll discover actual bones, but sometimes you find only footprints in fossilized mud. Our method is similarly indirect: Because we know which genes interact with which viruses, we can infer the types of viruses responsible for ancient disease outbreaks.”

Iron Age Nomads Likely Came from The Pontic-Caspian Steppe

Genomic analyses of nomads from Europe and Asia has revealed that the ancestors of most western Iron Age nomads were individuals from the eastern Pontic-Caspian steppe, a region that experienced great population movements during this time. These findings* shed light on the nomadic tribes that had significant impact on the cultural development of Eurasia. The Pontic-Caspian steppe, which connects eastern Europe to western Kazakhstan, was inhabited by nomadic populations during the Bronze and Iron Ages (1800 BCE to 400 CE). While their presence during this time is confirmed from archaeological research, the genomic structure of the Bronze Age peoples (the Srubnaya-Alakulskaya cultures) and of the Iron Age populations (including the Cimmerians, Scythians, and Sarmatians) in the region has not been fully explored. Maja Krzewińska and colleagues analyzed genomic data for 35 Bronze Age and Iron Age individuals from the Pontic-Caspian steppe from four chronologically sequential cultural groups: 13 Srubnaya-Alakulskaya individuals, 3 Cimmerians, 14 Scythians and 5 Sarmatians – all radiocarbon-dated to have lived between 1900 BCE and 400 CE. The researchers’ analyses of these individuals’ genomic data revealed many genetic links between the Cimmerians and Sarmatians, suggesting that they shared a common ancestral gene pool. However, no group can be deemed a direct ancestor of another group, Krzewińska et al. say. Despite no direct link, these individuals possess common genetic signatures maintained over the years from peoples from eastern fringes of the Pontic-Caspian steppe. This, say the authors, suggests western Eurasian steppe nomads that survived into the Iron Age were not direct descendants of the Bronze Age Srubnaya-Alakulskaya peoples, but rather, that they descended from peoples of the eastern Pontic-Caspian steppe region.

Research on ancient teeth reveals complexity of human evolution in Europe

PLOS ONE—Some of the dental features characteristic of Neanderthals were already present in Early Pleistocene Homo antecessor, according to a study* published September 19, 2018 in the open-access journal PLOS ONE by Laura Martín-Francés of the University of Bordeaux, France and colleagues.

Dental tissue proportions and enamel thickness are helpful features for identifying and distinguishing ancient hominins, reflecting unique developmental processes that arose in among hominin species. Neanderthals possess uniquely thin enamel compared to other hominins, but the origin and evolution of this condition is unknown. In this study, Martín-Francés and colleagues examined teeth from the Early Pleistocene hominin Homo antecessor, a potential ancestor of Neanderthals, to determine when this and other Neanderthal tooth features arose.

The authors examined 17 molars of Homo antecessor from the Gran Dolina-TD6 cave site in Sierra de Atapuerca in Northern Spain, dating back to the Early Pleistocene, 0.8-0.9 million years ago. They compared these teeth to more than 300 molars from other Homo species, living and extinct, from Asia, Africa, and Europe. Through micro-CT scans and high-resolution imaging, they determined that H. antecessor did not share the Neanderthal trait of thin enamel, but that the overall distribution of tooth tissues (enamel and dentine) in H. antecessor was in fact more similar to Neanderthals than to Homo sapiens and other hominins.

These findings suggest that certain aspects of Neanderthal tooth structure had already arisen in earlier hominins of Early Pleistocene Europe, but that the full suite of Neanderthal traits did not appear until later. The authors note that future study on hominins across the Early and Middle Pleistocene of Europe will further elucidate the evolutionary steps that produced the unique dentitions of Late Pleistocene hominins.

Martín-Francés summarizes: “The Early Pleistocene species, Homo antecessor (Atapuerca, Spain) shares the same molar enamel thickness with most hominins, including Homo sapiens. However, as early as 900,000 ago, Homo antecessor shows a few structural characteristics that are absent in the rest of the hominin species and will become the typical Neanderthal configuration.”

In another study**, fossil teeth from Italy, among the oldest human remains on the Italian Peninsula, show that Neanderthal dental features had evolved by around 450,000 years ago, according to the article published October 3, 2018 in the open-access journal PLOS ONE by Clément Zanolli of the Université Toulouse III Paul Sabatier in France and colleagues. These teeth also add to a growing picture of a period of complex human evolution that we are only beginning to understand.

Zanolli and colleagues examined dental remains from the sites of Fontana Fanuccio, located 50km southeast of Rome, and Visogliano, located 18km northwest of Trieste. At around 450,000 years old, these teeth join a very short list of fossil human remains from Middle Pleistocene Europe. Using micro-CT scanning and detailed morphological analyses, the authors examined the shape and arrangement of tooth tissues and compared them with teeth of other human species. They found that the teeth of both sites share similarities with Neanderthals and are distinct from modern humans.

There has been much debate over the identities and relationships of Middle Pleistocene ancient humans in Eurasia. The discovery of Neanderthal-like teeth so early in the record adds support to the suggestion of an early divergence of the Neanderthal lineage from our own, around the Early-Middle Pleistocene transition. The teeth are also notably different from other teeth known from this time in Eurasia, suggesting that there may have been multiple human lineages populating the region at this time, adding to a growing list of evidence that the Middle Pleistocene was a time of more complex human evolution than previously recognized.

Zanolli adds: “The remains from Fontana Ranuccio and Visogliano represent among the oldest human fossil remains testifying to a peopling phase of the Italian Peninsula. Our analyses of the tooth internal structural organization reveal a Neanderthal-like signature, also resembling the condition shown by the contemporary assemblage from Atapuerca Sima de los Huesos, indicating that an overall Neanderthal morphological dental template was preconfigured in Western Europe at least 430 to 450 ka ago.”

Traces of opiates found in ancient Cypriot vessel

UNIVERSITY OF YORK—Researchers at the University of York and the British Museum have discovered traces of opiates preserved inside a distinctive vessel dating back to the Late Bronze Age.

Vessels of this type, known as ‘base-ring juglets’, have long been thought to have links with opium use because when inverted they resemble the seed head of the opium poppy; they are known to have been widely traded in the eastern Mediterranean ca. 1650 – 1350BC.

Researchers used a range of analytical techniques to study a particular juglet housed in the British Museum, which is a sealed vessel, allowing the contents inside to be preserved. This meant that there was a rare opportunity for scientists to investigate what components might have survived.

Initial analysis by scientists at the British Museum showed that the juglet residue was mostly composed of a plant oil but hinted at the presence of opium alkaloids, a group of organic compounds derived from the opium poppy, and that are known to have significant psychological effects on the human body.

To conclusively detect the alkaloids and demonstrate the presence of opiates in the oil-based residue of the vessel, however, a new analytical technique was needed.

Using instruments in the Centre of Excellence in Mass Spectrometry at the University of York, Dr Rachel Smith developed the new analytical method as part of her PhD at the University’s Department of Chemistry.

Dr Smith said: “The particular opiate alkaloids we detected are ones we have shown to be the most resistant to degradation, which makes them better targets in ancient residues than more well-known opiates such as morphine.

“We found the alkaloids in degraded plant oil, so the question as to how opium would have been used in this juglet still remains. Could it have been one ingredient amongst others in an oil-based mixture, or could the juglet have been re-used for oil after the opium or something else entirely?”

In the past, it has been argued that these juglets could have been used to hold poppy seed oil, containing traces of opium, used for anointing or in a perfume. In this theory, the opium effects may have held symbolic significance.

Professor Jane Thomas-Oates, Chair of Analytical Science in the Department of Chemistry, and supervisor of the study at the University of York, said: “The juglet is significant in revealing important details about trade and the culture of the period, so it was important to us to try and progress the debate about what it might have been used for.

“We were able to establish a rigorous method for detecting opiates in this kind of residue, but the next analytical challenge is to see if we can succeed with less well-preserved residues.”

This is the first time that reliable chemical evidence has been produced to link the opium poppy with a base-ring juglet, despite many previous attempts by researchers over the years.

Dr Rebecca Stacey, Senior Scientist in the Department of Scientific Research at the British Museum, said: “It is important to remember that this is just one vessel, so the result raises lots of questions about the contents of the juglet and its purpose. The presence of the alkaloids here is unequivocal and lends a new perspective to the debate about their significance.”

Cuisine of early farmers revealed by analysis of proteins in pottery from Çatalhöyük

MAX PLANCK INSTITUTE FOR THE SCIENCE OF HUMAN HISTORY—Knowledge of the diet of people living in the prehistoric settlement of Çatalhöyük almost 8000 years ago has been complemented in astonishing scope and detail by analyzing proteins from their ceramic bowls and jars. Using this new approach, an international team of researchers has determined that vessels from this early farming site in central Anatolia, in what is now Turkey, contained cereals, legumes, dairy products and meat, in some cases narrowing food items down to specific species.

An international team led by researchers from the Max Planck Institute for the Science of Human History, the Freie Universität Berlin and the University of York has uncovered details about the diet of early farmers in the central Anatolian settlement of Çatalhöyük. By analyzing proteins from residues in ancient pots and jars excavated from the site, the researchers were able to find evidence of foods that were eaten there. Although previous studies have looked at pot residues from the site, this was the first to use proteins, which can be used to identify plants and animals more specifically, sometimes down to the species level.

One of the key early farming sites in the Old World

Çatalhöyük was a large settlement inhabited from about 7100 BC to 5600 BC by early farmers, and is located in what is now central Turkey. The site showcases a fascinating layout in which houses were built directly next to each other in every direction and stands out for its excellent preservation of finds. After over 25 years of excavation and analysis, it is considered one of the best-researched early farming sites in the Old World.

For this study, the researchers analyzed vessel sherds from the West Mound of Çatalhöyük, dating to a narrow timeframe of 5900-5800 BC towards the end of the site’s occupation. The vessel sherds analyzed came from open bowls and jars, as shown by reconstructions and had calcified residues on the inside surfaces. In this region today, limescale residue on the inside of cooking pots is very common. The researchers used state-of-the-art protein analyses on samples taken from various parts of the ceramics, including the residue deposits, to determine what the vessels held.

Food proteins left behind in ceramic bowls and jars

The analysis revealed that the vessels contained grains, legumes, meat and dairy products. The dairy products were shown to have come mostly from sheep and goats, and also from the bovine (cattle) family. While bones from these animals are found across the site and earlier lipid analyses have identified milk fats in vessels, this is the first time researchers have been able to identify which animals were actually being used for their milk. In line with the plant remains found, the cereals included barley and wheat, and the legumes included peas and vetches. The non-dairy animal products, which might have included meat and blood, came primarily from the goat and sheep family, and in some cases from bovines and deer. Interestingly, many of the pots contain evidence of multiple food types in a single vessel, suggesting that the residents mixed foods in their cuisine, potentially as porridges or soups, or that some vessels were used sequentially for different food items, or both.

Early cheese-making

One particular vessel however, a jar, only had evidence for dairy products, in the form of proteins found in the whey portion of milk. “This is particularly interesting because it suggests that the residents may have been using dairy production methods that separated fresh milk into curds and whey. It also suggests that they had a special vessel for holding the whey afterwards, meaning that they used the whey for additional purposes after the curd was separated,” states Jessica Hendy, lead author, of the Max Planck Institute for the Science of Human History. These results show that dairying has been ongoing in this area since at least the 6th millennium BC, and that people used the milk of multiple different species of animal, including cow, sheep and goat.

However, the researchers emphasize that based on the archaeological record an even greater variety of foods, especially plant foods, were likely eaten at Çatalhöyük, which either were not contained in the vessels they studied or are not present in the databases they use to identify proteins. The “shotgun” proteomic approaches used by the researchers are heavily dependent on reference sequence databases, and many plant species are not represented or have limited representation. “For example, there are only 6 protein sequences for vetch in the databases. For wheat, there are almost 145,000,” explains Hendy. “An important aspect of future work will need to be expanding these databases with more reference sequences.”

The potential of protein analysis on archaeological ceramics

Other molecular techniques applied to ancient pottery can reveal broad classes of food – such as evidence of dairy or animal fat – but an analysis of proteins allows a much more detailed picture of past cuisine. The results of this study show the power of protein analyses, which can identify foodstuffs in situ down to the species level, in samples as old as 8,000 years. In particular, the residues on the insides of the ceramics were exceptionally well-preserved and contained a wealth of information. The removal of these residues can be a common practice among archaeologists as part of the preservation and cleaning process. “These results highlight how valuable these deposits can be, and we encourage colleagues to retain them during post-excavation processing and cleaning,” states Eva Rosenstock of the Freie Universität Berlin and the senior author of the study.

Eighth-century skeleton found at Torcello

UNIVERSITÀ CA’ FOSCARI VENEZIA—On the island of Torcello, at the Ca’ Foscari University of Venice excavation site, some protagonists of the island’s thousand-year history have begun to emerge. A tomb datable to around 700 A.D. has recently been unearthed by the site’s team of scholars, who hail from universities throughout Italy, under the scientific direction of archaeologist Diego Calaon (a Marie Curie Fellow).

“The subject is a young adult, whose burial – not far from the area we imagine was used as a cemetery adjacent to the Basilica during the Early Middle Ages – maintained nearly the entire skeleton intact, with the exception of the head. We mustn’t be misled, however: the discovery of the residual parts of the right side of the skull and of the perforation coming from above (probably due to a construction pole) which occurred during modern times, indicate that the burial was complete and that the defects we see today resulted from activities which occurred later on in the area”.

The discovery is an important one: during the archaeological digs that took place on Torcello in the 1960s and 70s, cemetery sites were excavated, but for the most part only relatively modern ones pertaining to the High Middle Ages. Being able to analyze the biometric data of those who lived on Torcello from the sixth to ninth century presents a unique opportunity. Who were the ancient island residents who lived in the well-constructed wooden houses that were densely present in the area? Free workers? Slaves? Was this a community which already had deeply Christian roots, or not? If the burial site was isolated, or not connected directly to the Church, multiple hypotheses may arise: DNA and biometric analyses will reveal important interpretative data.

The burial has been excavated in an area which is particularly interesting in terms of stratigraphy: we are at the head of an ancient lagoon canal that separated the island of the Ancient Church of Saint Mary from the inhabited area of the medieval settlement: over time, the channel was fortified with hundreds of wooden poles, indicative of a “hunger for space” on the part of homes and craft businesses that required the enlargement and creation of new living spaces.

As the excavation has expanded, it has revealed how the eighth and ninth century were significant and demonstrative of the island’s population explosion: the presence of dense wooden houses, docks, fireplaces and production facilities, proven by hundreds of ceramic fragments from kitchen pottery (including many covering basins, the dishes of yesteryear for cooking breads and cakes in fireplaces on the ground), amphorae for oil and wine, and soapstone vessels for cooking soups and stews.

The inhabited area includes a large number of warehouses, constructed and active in the two previous centuries, from 500-600 A.D.: “Torcello became a hub of movement within the lagoon precisely at this moment. Altino was no longer feasible as a port, and the warehouses that we are excavating on the island,” explains Diego Calaon, “are revealing that long before the ‘imagined’ or ‘legendary’ barbaric destruction occurred, the local elite had fully invested in creating an efficient ship yard precisely in the littoral area of the time. Warehouses were built with reused Roman bricks, some with markings on them, fashioned with stones taken from ancient Rome. The porticoed harbor warehouse visible on Torcello nowadays is exceptionally well preserved: we will be able to clean up the interiors within 5/10 days of work”. Thanks to the Torcello Abitata project and archaeology talks also attended by the citizenry, inhabitants as well as external interested parties will be able to discover more.

Meanwhile, there is another project underway at a different location where a construction of large dimensions (more than 25 meters in length), which may be interpreted as a boat garage and warehouse datable to the fourteenth century, is currently undergoing excavation and study. The structure, with a solid stone foundation (again, “pieces” from Altino which were salvaged for use here in the lagoon) sits opposite a very old and sturdy stone-laid riverbank, which was subsequently reinforced by an outward-facing jetty reaching where the Sile river used to flow. Between the riverbank and the warehouse, there are obvious and abundant characteristics of a medieval shipyard for organizing and holding boats, probably for fishing, with traces of poles for hauling, for lateral mooring and, probably, for preparing pitches.

It is a history rich with elements which is a marvel to discover from one day to the next.

Lidar survey ‘compels’ revaluation of aspects of ancient Maya society

AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE—An airborne laser mapping survey of over 2,000 square kilometers of northern Guatemala – the largest such survey to date of this region – “compels” a revaluation of Maya demography, agriculture, and political economy, according to its authors. The Lidar survey data, which identified over 61,000 ancient structures hidden amidst the dense tropical forests of the region, was further analyzed by multi-national, interdisciplinary teams, whose interpretations of urban and rural density and transportation networks, among other facets, suggest that future field work should involve a reevaluation of settlement and land use of the Classic lowland Maya. Lidar, a technology that uses pulses of laser light to map land cover and topography in 3-D, has allowed archaeologists to study ancient Maya society on a regional scale. Due to the heavily forested areas throughout much of the central Maya Lowlands, discovering new sites is difficult – fully mapping and characterizing a single settlement can take many years. As such, data concerning ancient Maya urbanism, population, land use and socio-political complexity has been limited. Aerial Lidar survey, however, can map large areas of the ground surface below the forest canopy quickly and in detail, recording ancient structures, roadways or agricultural features at a landscape scale. Here, Marcello Canuto and colleagues present the results* of what they call the largest Lidar survey to date of the lowland Maya region. Canuto et al. mapped 12 separate areas in Petén, Guatemala, to characterize Maya settlement, from cities to hinterland, across varied regions of the Maya Lowlands. Using the data, authors estimate upwards of 11 million people lived throughout the Maya Lowlands during the Late Classic Period (650 – 800 CE), numbers in agreement with previous estimates. But populations of such scale would have required some degree of agricultural intensification – the extent of which has previously been unknown for the region – to sustain them, say the authors. Their work now demonstrates that a great deal of the wetlands throughout the region were heavily modified for agricultural use. What’s more, networks of roadways connected distant cities and towns – some of which were heavily fortified, an unexpected finding according to the authors. In a related Perspective, Anabel Ford and Sherman Horn caution against relying solely on Lidar data and suggest it should not replace traditional “boots on the ground” archaeological survey methods.

Precision or Power? Evidence for Precise Hand Movements in Neanderthals

AAAS—Muscle attachment scars on Neanderthal hands show similarities to the hands of lifelong precision workers, a new study reports. This finding challenges the common belief that Neanderthals relied primarily on force, rather than precision, in their daily activities. The manual activities of Neanderthals are particularly important, as they provide insights into the evolution of tool making and use. Despite work hinting that Neanderthals were anatomically able to perform precision grips using their thumb and index finger like modern humans, there has been no clear evidence that Neanderthals habitually used precise hand movements. New archaeological research on Neanderthal tools, however, such as on bone tools for hide processing, has shown proof of Neanderthal activities that would require fairly high levels of precision; this has resurfaced the question of whether Neanderthals precisely grasped in their daily activities. Attempting to find an answer, Fotios Alexandros Karakostis et al. first used a new 3-D method to analyze hand entheseal surfaces (muscle attachment scars) of modern-day power gripping laborers like construction workers, as compared to modern-day workers, like tailors and artists, in lower-intensity jobs. They identified patterns of entheses indicating significant muscle use relating to power versus precision grips, which allowed them to provide a reliable way to reconstruct habitual physical activities in the past. They then applied this approach to fossil samples of Neanderthals and early modern humans from the Late Middle to Late Pleistocene. The fossils were from locations in Europe, Western Asia and North Africa. Both groups, the Neanderthals and early modern humans, were represented by a total of six individuals each whose entheses were preserved. Neanderthals consistently exhibited characteristics of high systematic precision grasping, the authors say. Contrarily, early modern humans showed signs of both precision and power grasping.

Painted tomb discovered in Cumae (Italy): A banquet frozen in time

CNRS—At the foot of the hill on which sits the ancient city of Cumae, in the region of Naples, Priscilla Munzi, CNRS researcher at the Jean Bérard Centre (CNRS-EFR), and Jean-Pierre Brun, professor at the Collège de France, are exploring a Roman-era necropolis. They now reveal the latest discovery to surface in the archaeological dig they have led since 2001: a painted tomb from the 2nd century B.C. In excellent condition, the tomb depicts a banquet scene, fixed by pigments.

Twice the size of Pompeii, the ancient city of Cumae is located 25 km west of Naples on the Tyrrhenian Sea facing the island of Ischia, at the Campi Flegrei Archaeological Park. Ancient historians considered Cumae the oldest Ancient Greek settlement in the western world. Founded in the latter half of the 8th century B.C. by Greeks from Euboea, the settlement grew quickly and prospered over time. 

In recent years, French researchers have focused on an area where a Greek sanctuary, roads and a necropolis were found. Among the hundreds of ancient sepulchers unearthed since 2001, they have discovered a series of vaulted burial chambers made of tuff, a volcanic stone found in the area. People entered the tomb through a door in the façade sealed with a large stone block. The space inside was generally composed of a chamber with three vaults or funerary beds. The tombs were raided in the 19th century, but recovered remains and traces of funerary furnishings, which archaeologists have used to date the tombs to the second century B.C., indicate the high social status of those buried within. 

Until now, only tombs painted red or white had been found, but in June 2018 researchers discovered a room with exceptionally executed figure painting. A naked servant carrying a jug of wine and a vase is still visible; the banquet’s guests are thought to have been painted on the side walls. Other elements of the banquet can also be distinguished. In addition to the excellent state of conservation of the remaining plaster and pigments, such a décor in a tomb built in that period is rare; its “unfashionable” subject matter was in vogue one or two centuries earlier. This discovery is also an opportunity to trace artistic activity over time at the site.

To preserve the fresco, archaeologists removed it, along with fragments found on the ground, in order to re-assemble the décor like a puzzle. 

The digs were carried out with financial support from the French Ministry of Europe and Foreign Affairs, the Ecole française de Rome and the Fondation du Collège de France. This research is part of a concession granted by the Italian Ministry of Cultural Assets and Activities in partnership with the Phlegraen Fields archaeological site.

Violence in pre-Columbian Panama exaggerated, new study shows

SMITHSONIAN TROPICAL RESEARCH INSTITUTE—Buried alive.  Butchered.  Decapitated.  Hacked.  Mutilated.  Killed.  Archaeologist Samuel K. Lothrop did not obfuscate when describing what he thought had happened to the 220 bodies his expedition excavated from Panama’s Playa Venado site in 1951. The only problem is that Lothrop likely got it wrong. A new evaluation of the site’s remains by Smithsonian archaeologists revealed no signs of trauma at or near time of death. The burial site likely tells a more culturally nuanced story.

The “long-overdue” reexamination of the Playa Venado site, which dates to 500-900 A.D. and is located near the Pacific entrance to the Panama Canal, revealed no evidence of ritual killing, said Nicole E. Smith-Guzmán, post-doctoral fellow at the Smithsonian Tropical Research Institute (STRI). Lothrop’s misinterpretations are likely due to the era of “romantic archaeology,” underdeveloped methods for mortuary studies and literal readings of Spanish accounts of indigenous peoples after European contact.

“We now realize that many of these Spanish chroniclers were motivated to show the indigenous populations they encountered as ‘uncivilized’ and in need of conquering,” said Smith-Guzmán, adding that many accounts of sacrifice and cannibalism have not been confirmed by the archaeological record. “Rather than an example of violent death and careless deposition, Playa Venado presents an example of how pre-Columbian societies in the Isthmo-Colombian area showed respect and care for their kin after death.”

The article*, co-authored by STRI staff archaeologist Richard Cooke, was published in Latin American Antiquity. But Lothrop’s 1954 paper, “Suicide, sacrifice and mutilations in burials at Venado Beach, Panama,” left its mark on the annals of Panamanian archaeology. It has been cited more than 35 times as evidence of violence, cannibalism or trophy decapitation. Some authors have used the paper to suggest Playa Venado is a mass burial site or a manifestation of conflict.

In defense of Lothrop, who was an archaeologist with Harvard University’s Peabody Museum of Archaeology and Enthnology, bioarchaeology (the study of human remains from archaeological contexts) did not exist as a sub-discipline until two decades after his work concluded at Playa Venado. Today’s practitioners also benefit from methods developed in the 1980s and 1990s.

Lothrop’s careful documentation and preservation of remains made reevaluation possible. Remains from more than 70 individuals from Playa Venado are at the Smithsonian’s National Museum of Natural History, sent there by Lothrop for osteological evaluation.

Upon examination, Smith-Guzmán found only wounds that showed signs of healing well before the individuals died, including blows to the head and a dislocated thumb. Various broken bones and disarticulated remains discovered by Lothrop are more likely explained by normal processes of decomposition and secondary burial of remains, which is believed to have a common ancestor-veneration practice in pre-Colombian Panama.

Evidence suggests certain people’s remains were preserved for long periods of time before being buried in ritual contexts. “At Playa Venado, we see a lot of evidence of adults being buried next to urns containing children, multiple burials including one primary and one secondary burial, and disturbance of previously laid graves in order to inter another individual in association,” said Smith-Guzmán.

“The uniform burial positioning and the absence of perimortem (around the time of death) trauma stands in contradiction to Lothrop’s interpretation of violent death at the site,” said Smith-Guzmán, who also used evidence from other archaeological sites around Panama about burial rites as part of the investigation. “There are low rates of trauma in general, and the open mouths of skeletons Lothrop noted are more easily explained by normal muscle relaxation after death and decay.”

Smith-Guzmán and Cooke’s reassessment of the Playa Venado burials suggests that ideas about widespread violence in pre-Columbian Panama need to be reconsidered. The research is part of a larger, interdisciplinary site reanalysis that will be published by the Dumbarton Oaks Museum in Washington, D.C..

Smith-Guzmán’s previous discovery of the first case of bone cancer in Latin America is featured on this month’s Smithsonian Sidedoor podcast.

Research proves South East Asian population boom 4,000 years ago

AUSTRALIAN NATIONAL UNIVERSITY—Researchers at The Australian National University (ANU) have uncovered a previously unconfirmed population boom across South East Asia that occurred 4,000 years ago, thanks to a new method for measuring prehistoric population growth.

Using the new population measurement method, which utilizes human skeletal remains, they have been able to prove a significant rapid increase in growth across populations in Thailand, China and Vietnam during the Neolithic Period, and a second subsequent rise in the Iron Age.

Lead researcher Clare McFadden, a PhD Scholar with the ANU School of Archaeology and Anthropology, said the population trend was consistent across samples taken from 15 locations.

“We saw huge population growth associated with the agricultural transition,” McFadden said.

“Up until about 4,000 years ago you have hunter gatherer type populations, then you have the introduction and intensification of agriculture.

“Agricultural transition has been widely studied around the world and we consistently see significant population growth as a result.”

The reason these population changes have never been quantified before is because the tools used to measure prehistoric populations were all designed for Europe and the Americas where archaeological conditions are different from that of Asia.

Ms McFadden said the difference comes down to how children are represented in population numbers.

“For skeletal remains in Europe and America we often see the complete absence of infants and children, they are very poorly represented,” she said.

“The preservation isn’t good – small bones don’t preserve well. Children are also thought to often be buried in a different cemetery to adults.

“So the method researchers used to measure populations excluded children because they didn’t have accurate representation.”

Ms McFadden said her new method for determining the rate of natural population increase takes into account the proportion of infants and children compared to the total population. This way researchers were able to bring population growth figures in line with other archaeological evidence in the region which suggested a rapid rise.

“In South East Asia and the Pacific, we actually have pretty good preservation of bones from children,” she said.

“The skeletal evidence was there, we were seeing populations with huge numbers of infants and children compared to the adult populations, which suggests it was a growing population at that time. But the existing tools weren’t detecting that growth.

“The trends the new tool found aligned perfectly with what researchers expect to see in response to agriculture.”

Casting Archaeological Doubt on the Meghalayan Age

American Association for the Advancement of Science (AAAS)—The creation of a new division in the scale of geological time – the Meghalayan Age, a period beginning with a two-century megadrought in 2200 BCE that allegedly led to the collapse of several civilizations worldwide – was recently announced by the International Commission of Stratigraphy. In a Perspective*, Guy Middleton argues that the archaeological and historical evidence does not support the widespread collapse in which the Meghalayan is based. According to Middleton, this lack of evidence casts doubts on the utility of using 2200 BCE as a meaningful threshold of a new geologic age. Large amounts of paleoclimate data suggestive of the existence of a megadrought have been casually linked to the collapse of civilizations for decades. However, these environmentally deterministic interpretations often fail to account for specific historical circumstances or the power of human agency to translate environmental factors into cultural and socio-political contexts. For example, the ‘collapse’ of Egyptian civilization is often provided as evidence of the impact of the Meghalayan megadrought. According to Middleton, there was no great disruption to Egyptian society during this time, but rather a reorganization of political power. Furthermore, the ancient literary sources that have been cited as evidence of drought, famine and unrest during this time – were written far later and with a purpose of supporting the centralized power of a Pharaoh; they cannot be accepted at face value. Middleton suggests that archaeologists pursue more interdisciplinary collaborations and publish in journals so current understandings are visible to the wider discourse.

International study suggests ancient globalization

UNIVERSITY OF CENTRAL FLORIDA—Using energy consumption as a measure, a team of international scientists has found that ancient civilizations engaged in globalization more than previously believed, suggesting that an integrated global economy is nothing new and may have benefited societies for ages.

This archaeological research is the first of its kind, because instead of focusing on specific regions or cultures, it used radiocarbon dating to examine human societies on a broader and longer-term scale.

The findings are the result of a study co-authored by Jacopo A. Baggio, an assistant professor in the University of Central Florida political science department, and published today in the journal Proceedings of the National Academy of Sciences.

The research team included lead author Jacob Freeman, an assistant professor of archaeology at Utah State University, and Erick Robinson, a postdoctoral assistant research scientist in the Department of Anthropology at the University of Wyoming

The researchers found that societies often experienced booms and busts simultaneously, a process known as synchrony.

They used radiocarbon dating and historical records to measure energy consumption through a period of history ranging from about 10,000 to 400 years ago, a time frame that encompasses a large portion of the current Holocene era.

The greater the energy consumption, the more likely a society was booming with population and political and economic activity.

Some of the areas examined included the western United States, the British Isles, Australia and northern Chile.

The radiocarbon dates came from preserved organic items such as seeds, animal bones and burned wood from ancient trash deposits at these sites. Radiocarbon dating measures the radioactive decay of the atom carbon-14 from organic matter to find the organic matter’s age.

The researchers’ findings suggest that early globalization was possibly a strategy for societies to grow through migration, trade and conflict with other, distant societies when a society’s carrying capacity began to be overloaded.

Baggio, who is also a member of UCF’s National Center for Integrated Coastal Research and the Sustainable Coastal System research cluster, said it is especially important to study societies’ resilience, or ability to recover from a disaster, over the long term, and radiocarbon dating is a useful tool for this assessment.

“Resilience is intrinsically dynamic,” Baggio said. “So, it becomes very hard to understand resilience in a short time span. Here we have the opportunity to look at these longer trends and really see how society has reacted and adapted and what were the booms and busts of these societies. Hopefully this can teach some lessons to be learned for modern day society.”

The researcher said the rise and fall of societies seems to be an inherent part of civilization.

“Our data stop at 400 years ago, and there has been a huge change from organic economies to fossil fuel economies,” Baggio said. “However, similar synchronization trends continue today even more given the interdependencies of our societies.”

Freeman said the new study suggests the process of societies creating connections and becoming interdependent, known as globalization, also played out among human society millennia ago.

“If every culture was unique, you would expect to see no synchrony, or harmony, across human records of energy consumption,” Freeman said.

Robinson said it is important to look at not only cultures at specific times, but also over the long term.

“We must move back and forth between different spatial and temporal scales in order to understand the whole picture,” Robinson said.

“When we take a broader perspective, we are still interdependent on others, no matter our cultural differences,”

Although interconnectedness has advantages for societies, there can be downfalls as well, Robinson said.

“The more tightly connected and interdependent we become, the more vulnerable we are to a major social or ecological crisis in another country spreading to our country,” he said. ‘The more we are synced, the more we put all our eggs in one basket, the less adaptive to unforeseen changes we become.”

“The financial crisis of 2007 to 2008 is a good recent example,” Robinson said.
