A team of archaeologists is surveying and excavating the remains of a major ancient Mycenaean citadel—an archaeological site featuring ruins that are turning out to be much more extensive than what meets the naked eye.

Under the leadership of Associate Professor Christofilis Maggidis of Dickinson College and the auspices of the Athens Archaeological Society, teams of specialists have been systematically surveying an imposing, island-like, flat-topped bedrock outcrop that rises 20-40 meters above a surrounding plain with a summit area stretching 49.5 acres at the northeastern edge of the Kopais basin in southeastern Greece. Known as the citadel of Glas and identified as consisting of ancient Mycenaean structures, the summit area featuring the ruins is estimated to measure ten times the size of the ancient citadel of Mycenaean Tiryns and seven times that of Mycenae, the famed city of Agamemnon of Homer’s Iliad.

“I first excavated at Glas in 1990 as a graduate student with my mentor, the late Spyros Iakovidis,” said Maggidis. “The unparalleled size of the citadel, its connection with the gigantic drainage project of Kopais, and the discovery of such important but few remains in the citadel indicating that the rest of the citadel was left vacant puzzled me since then.”

Begun in the 14th century BC, the drainage project of Kopais was a large-scale engineering effort of massive proportions which transformed the Kopais basin into what became the most fertile plain on mainland Greece. The ancient engineers drained marshland through a complex drainage control system, diverting six rivers and streams from the basin into two enormous canals that converged at the northeastern edge of the Kopais basin. The canals were flanked by massive embankments reinforced at some locations with double Cyclopean revetments that supported roads and were supplied with underground drains and channels directing water overflow into artificial polders, natural cavities and sinkholes, or to the Larymna bay. Archaeologists estimate that as much as 2,000,000 cubic meters of earth were moved to build dykes and embankments along the periphery of the basin, with more than 250,000 cubic meters of stone used to face the embankments.

Thought to be the administrative center for this expansive system, the citadel of Glas was protected by a massive Cyclopean wall about 5.50-5.80 meters thick, running along the edge of the natural outcrop summit platform and defining the periphery of the citadel for approximately 3 kilometers, featuring four gates and a cluster of three adjacent central enclosures. But, said Maggidis, “the citadel of Glas presented the lay-out of a fort with certain spatial peculiarities: only one third or less of the total area of the citadel (49.5 acres) seemed to be occupied by various buildings and structures (administrative buildings, storage facilities, workshops, kitchens, personnel residence quarters), whereas no other ruins had been located so far by surface survey anywhere else in the citadel.” The space outside the central enclosures, in other words, appeared to be void of structures. Why?

For Maggidis, this just didn’t add up.

“I was convinced that Glas was much more than a fort administrating the drainage works of the Kopais lake and the local agricultural production, and decided to investigate the site further.”

And investigate he did.

Beginning in 2010, Maggidis and colleagues conducted a systematic geophysical survey of the citadel using ground penetrating radar (GPR), a Fluxgate gradiometer, electrical resistivity, and satellite imagery. The team focused primarily on unexplored areas and some already excavated sectors.

The results were illuminating.

“The citadel of Glas was not left void of structures outside the central enclosures after all, but was apparently covered with many buildings of various uses, including at least five large and well-built complexes, extensive residential quarters and clusters of buildings stretching between these complexes, (semi)circular structures (silos?), a cistern, staircases, retaining walls and terraces. This is the picture of a fortified town.”

Maggidis and colleagues had come much closer to uncovering the true proportions and complexity of the citadel. But looking ahead, he sees much more to be done.

“The systematic investigation of the Mycenaean citadel of Glas will continue and intensify in the next decade,” says Magiddis. “The geophysical survey will focus on the eastern (Sector IV) and the western part of the citadel (Sector V), while systematic excavation will target select building complexes, clusters, and structures.”

More information about the Glas survey and excavations can be obtained at the project website. A detailed article about the discoveries at the citadel of Glas will be published in the upcoming September issue of Popular Archaeology Magazine.

Original hand-written working notes of Bram Stoker on paper, grist that would find its way into his famous signature book, Dracula;

An original manuscript of James Joyce’s Ulysses;

The first and only existing printing of Benjamin Franklin’s Poor Richard’s Almanac; 

More than 100 personally inscribed letters of George Washington;

Parts of manuscripts from Charles Dickens’ Pickwick Papers and Nicholas Nickleby…………

These are but a tiny sampling of the holdings of the Rosenbach of the Free Library of Philadelphia, tucked almost inconspicuously among a row of 19th-century townhouses in the Rittenhouse-Fitler historic district in the center of bustling Philadelphia. It presents a streetside appearance that doesn’t turn heads like other major tourist sites in this city.

But make no mistake. Its outward appearance belies its significance. Within its walls is a collection of thousands of the original first-print books, manuscripts, letters, illustrations and other works of art of some the most famous and noteworthy literary, historical and artistic figures of the past, a treasure house for historians, historical archaeologists, others doing primary research………and for you and me. What arguably distinguishes it from most museums and archives of its kind is its offering of an up-close and personal experience: With a scheduled Hands-on Tour, the museum curators will permit the visitor to hold and turn the pages of an early printing of a book like Lewis Carroll’s Alice in Wonderland, or read from an original manuscript like Joseph Conrad’s Lord Jim, or view drawings made by William Blake himself.

The namesake institution was founded in 1954 by Dr. A.S.W. Rosenbach and his brother, Philip. As book, manuscript, and fine art dealers, they were also instrumental in the establishment of private libraries that became the repository for important rare books. Among these libraries are the well known Folger and Huntington Libraries. In the 1970’s, the Rosenbach became the central repository for the works of Maurice Sendak (author and illustrator of the book, Where the Wild Things Are, among others), and remains so today. 

Now, for the first time, the Rosenbach has opened a special exhibit for the general public displaying pages from the manuscript of James Joyce’s Ulysses, side-by-side with the Shakespearean plays and poems that inspired it. It will show until August 31, 2014. And until November 2, 2014, visitors can view an exhibit that relates how Maurice Sendak’s art reflected the effects of events in his life that caused personal turmoil. 

For those of us who like books, old things, and history, it could pleasantly top off a memorable visit to this historic city.

Popular Archaeology Magazine, an exclusively digital, U.S.-based magazine dedicated to publishing new discoveries, developments and opportunites in archaeology and anthropology for a general and scholarly readership, has released two new versions of its quarterly publication designed for access through smartphones and tablets. The most recent issue, published in June, 2014, features stories about the news-making discoveries related to early humans in the Arabian Peninsula; excavations at a massive Bronze Age city-state site in Jordan; new discoveries at Mycenae, the city of Agamemnon; the excavation and preservation of a lost city in South America; a scientific report on excavations at Sima de las Palomas, a Neanderthal site in Spain; and a scientific report on excavations that have turned up 800,000-year-old early human remains, also in Spain. Readers can access the magazine app at The App and the ebook version at Amazon.com.

Once again, scientists examining an ancient human fossil are finding that the path of human evolution, at least over the last 100,000 years, is not as simple as evolutionists have thought.

In a recent study, researchers Xiu-Jie Wu, Wu Liu and Song Xing of the Institute of Vertebrate Paleontology and Paleoanthropology, Beijing, Isabelle Crevecoeur of PACEA, Université de Bordeaux, France, and Erik Trinkaus of Washington University in St. Louis, re-examined a circa 100,000-year-old archaic human skull originally found during excavations 35 years ago at the Xujiayao site in China’s Nihewan Basin. Based on their micro-CT scans of the interior configuration of the temporal bone, they found that the inner-ear formation closely resembled a formation long thought to occur only in Neanderthals.

“We were completely surprised,” Trinkaus said. “We fully expected the scan to reveal a temporal labyrinth that looked much like a modern human one, but what we saw was clearly typical of a Neandertal. This discovery places into question whether this arrangement of the semicircular canals is truly unique to the Neandertals.” Moreover, he said, “the discovery places into question a whole suite of scenarios of later Pleistocene human population dispersals and interconnections based on tracing isolated anatomical or genetic features in fragmentary fossils. It suggests, instead, that the later phases of human evolution were more of a labyrinth of biology and peoples than simple lines on maps would suggest.”

Often well-preserved in mammal skull fossils, the semicircular canals are remnants of a fluid-filled sensing system that helps humans maintain balance when they change their spatial orientations, such as when running, bending over or turning the head from side-to-side.

Since the mid-1990s, when early CT-scan research confirmed its existence, the presence of a particular arrangement of the semicircular canals in the temporal labyrinth has been considered enough to securely identify fossilized skull fragments as being from a Neanderthal. This pattern is present in almost all of the known Neanderthal labyrinths. It has been widely used as a marker to set them apart from both earlier and modern humans.

The skull at the center of this study, known as Xujiayao 15, was found along with an assortment of other human teeth and bone fragments, all of which seemed to have characteristics typical of an early non-Neanderthal form of late archaic humans.

Trinkaus, who has studied Neanderthal and early human fossils from around the globe, said this discovery only adds to the rich confusion of theories that attempt to explain human origins, migrations patterns and possible interbreedings.

“The study of human evolution has always been messy, and these findings just make it all the messier,” Trinkaus said. “It shows that human populations in the real world don’t act in nice simple patterns.”

Research details are published in the Proceedings of the National Academy of Sciences.

Gone are the days when paleoanthropologists could characterize the path of human evolution as a simple, single homogenous line of progressive changes in human morphology and behavior. Or so suggests a collaborative group of scientists who, as detailed in a study published in the July 4, 2014 issue of Science, came up with a new synthesis, or at least the rudimentary framework of one. It is a developing scenario that, they argue, more accurately explains how earlier forms of Homo (early humans) and their Australopithecus forerunners eventually led to the emergence of Homo sapiens (modern humans), the last surviving hominin.

Led jointly by Susan Antón, professor of anthropology at New York University, paleoanthropologist Richard Potts, curator of anthropology and director of the Human Origins Program at the Smithsonian’s National Museum of Natural History, and Leslie Aiello, president of the Wenner-Gren Foundation for Anthropological Research, the team studied paleoclimate, fossil, and stone tool evidence, leading to a developing consensus that suggests a rethinking of long-held assumptions about human origins and evolution. Based on a synthesis of the data, the researchers point to change and diversity of environmental conditions and the compelling need to survive by adapting to the changing conditions as a key to understanding how early humans were able to vary, survive and begin spreading from Africa to Eurasia 1.85 million years ago. The process entailed a diversification of species and genera differentiating and overlapping in time and morphology, beginning with some key elements once thought to define Homo but actually evolving in earlier Australopithecus ancestors between 3 and 4 million years ago.

Significant to the development of the new synthesis, Potts developed a new climate framework for East African human evolution that depicts most of the era from 2.5 million to 1.5 million years ago as a time of strong climate instability and shifting intensity of annual wet and dry seasons.

“Unstable climate conditions favored the evolution of the roots of human flexibility in our ancestors,” said Potts.  “The narrative of human evolution that arises from our analyses stresses the importance of adaptability to changing environments, rather than adaptation to any one environment, in the early success of the genus Homo.”

Between 2.1 and 1.8 million years ago, the oldest known species of the human genus, Homo, exhibited diverse traits. These species include the 1470 Group and the 1813 Group, based on the Kenyan fossils KNM-ER 1470 (left) and KNM-ER 1813 (second from left), respectively. By 1.8 to 1.9 million years ago, the species Homo erectus had evolved in Africa and started to spread to Eurasia. Early populations of this long-lived species are represented by the Kenyan fossil KNM- ER 3733 (right) and the Georgian fossil Dmanisi Skull 5 (second from right). The three lineages — the 1470 group, the 1813 group, and Homo erectus — overlapped in time for several hundred thousand years. The Kenyan fossils, from the site of Koobi Fora in the Lake Turkana region of Kenya, are housed in the National Museums of Kenya. Fossils from Dmanisi are housed in the Georgian National Museum.

Their analysis and conclusions could explain, at least in part, much of the new evidence that has emerged in recent years suggesting that multiple coexisting species of Homo overlapped geographically and developed differentiating morphological and behavioral characeristics. It contrasts with the long-held model of a large brain, long legs, the ability to craft tools and prolonged maturation periods evolving together as a single package at the start of the Homo lineage as African grasslands expanded and Earth’s climate became cooler and drier.

The researchers also analyzed ancient stone tools, isotopes found in teeth and cut marks found on animal bones in East Africa.

“Taken together, these data suggest that species of early Homo were more flexible in their dietary choices than other species,” said Aiello. “Their flexible diet—probably containing meat—was aided by stone tool-assisted foraging that allowed our ancestors to exploit a range of resources.”

The study authors concluded that flexibility likely strengthened the ability of human ancestors to successfully adapt to changing environments and emerge out of Africa, and explains the ability of the modern human species to occupy diverse habitats throughout the world.

The detailed study is published in the July 4, 2014 issue of Science magazine.

Tibetans were able to adapt to high altitudes thanks to a gene acquired when their ancestors mated with a species of human they helped push to extinction, according to a new report by University of California, Berkeley, scientists.

An unusual variant of a gene involved in regulating the body’s production of hemoglobin – the molecule that carries oxygen in the blood – became widespread in Tibetans after they moved onto the high-altitude plateau several thousand years ago. This variant allowed them to survive despite low oxygen levels at elevations of 15,000 feet or more, whereas most people develop thick blood at high altitudes, leading to cardiovascular problems.

“We have very clear evidence that this version of the gene came from Denisovans,” a mysterious human relative that went extinct 40,000-50,000 years ago, around the same time as the more well-known Neanderthals, under pressure from modern humans, said principal author Rasmus Nielsen, UC Berkeley professor of integrative biology. “This shows very clearly and directly that humans evolved and adapted to new environments by getting their genes from another species.”

This is the first time a gene from another species of human has been shown unequivocally to have helped modern humans adapt to their environment, he said.

Nielsen and his colleagues at BGI-Shenzhen in China will report their findings online July 2 in advance of publication in the journal Nature.

The gene, called EPAS1, is activated when oxygen levels in the blood drop, triggering production of more hemoglobin. The gene has been referred to as the superathlete gene because at low elevations, some variants of it help athletes quickly boost hemoglobin and thus the oxygen-carrying capacity of their blood, upping endurance. At high altitude, however, the common variants of the gene boost hemoglobin and its carrier, red blood cells, too much, increasing the thickness of the blood and leading to hypertension and heart attacks as well as low-birth-weight babies and increased infant mortality. The variant or allele found in Tibetans raises hemoglobin and red blood cell levels only slightly at high elevation, avoiding the side-effects seen in most people who relocate to elevations above 13,000 feet.

“We found part of the EPAS1 gene in Tibetans is almost identical to the gene in Denisovans and very different from all other humans,” Nielsen said. “We can do a statistical analysis to show that this must have come from Denisovans. There is no other way of explaining the data.”

The researchers first reported the prevalence of a high-altitude version of EPAS1 in Tibetans in 2010, based on sequencing of the genomes of numerous Han Chinese and Tibetans. Nielsen and his colleagues argued that this was the result of natural selection to adapt to about 40 percent lower oxygen levels on the Tibetan plateau. That is, people without the variant died before reproducing at a much higher rate than those with it. About 87 percent of Tibetans now have the high-altitude version, compared to only 9 percent of Han Chinese, who have the same common ancestor as Tibetans.

Nielsen and his colleagues subsequently sequenced the EPAS1 gene in an additional 40 Tibetans and 40 Han Chinese. The data revealed that the high-altitude variant of EPAS1 is so unusual that it could only have come from Denisovans. Aside from its low frequency in Han Chinese, it occurs in no other known humans, not even Melanesians, whose genomes are nearly 5 percent Denisovan. A high quality sequence of the Denisovan genome was published in 2012.

Nielsen sketched out a possible scenario leading to this result: modern humans coming out of Africa interbred with Denisovan populations in Eurasia as they passed through that area into China, and their descendants still retain a small percentage – perhaps 0.1 percent – Denisovan DNA. The group that invaded China eventually split, with one population moving into Tibet and the other, now known as Han Chinese, dominating the lower elevations.

He and his colleagues are analyzing other genomes to pin down the time of Denisovan interbreeding, which probably happened over a rather short period of time.

“There might be many other species from which we also got DNA, but we don’t know because we don’t have the genomes,” Nielsen said. “The only reason we can say that this bit of DNA is Denisovan is because of this lucky accident of sequencing DNA from a little bone found in a cave in Siberia. We found the Denisovan species at the DNA level, but how many other species are out there that we haven’t sequenced?”

Nielsen’s coauthors include former UC Berkeley postdoctoral fellow Emilia Huerta-Sánchez, now at UC Merced; postdocs Benjamin Peter and Nicolas Vinckenbosch of UC Berkeley’s Department of Integrative Biology; and colleagues in China, Hong Kong, Denmark, Saudi Arabia and Turkey.

Researchers have found that birth rates and life expectancy in the American Southwest between 900 BC and 1400 AD indicated a period of rapid population growth between about 500 AD and 1100 AD followed by a significant decline after 1300 AD, never again to recover the former growth.

The study, conducted with National Science Foundation funding by anthropology professor Tim Kohler and graduate student Kelsey Reese, both of Washington State University, analyzed data on thousands of human remains found at hundreds of sites across the Four Corners region of the Southwest. The data helped to create a chronology of the region’s “Neolithic Demographic Transition” — a time period when stone tool artifacts signaled the agricultural transition from cutting meat to pounding grain.  

“It’s the first step towards all the trappings of civilization that we currently see,” said Kohler.

Maize (corn), the region’s staple crop, was introduced as early as 2000 BC, but productivity was slow to rise until about 400 BC, said Kohler, when the crop is estimated to have provided around 80 percent of the regional population’s calories. A corresponding gradual rise in birth rates ensued until about 500 A.D.

Then, growth rates varied across the region. People in the Sonoran Desert and Tonto Basin, in what is today Arizona, were more culturally advanced, with irrigation, ball courts, and eventually elevated platform mounds and compounds housing elite families. Yet birth rates were higher among people to the north and east, in the San Juan basin and northern San Juan regions of northwest New Mexico and southwest Colorado.

Kohler suggested that the Sonoran and Tonto people might have had difficulty finding new farming opportunities for their posterity, as corn farming required irrigation. Water from canals may have also carried harmful protozoa, bacteria and viruses. But groups to the northeast would have been able to expand maize production into new areas as their populations grew, he said.

Around 900 A.D., populations remained high but birth rates began to fluctuate. The mid-1100s saw one of the largest known droughts in the Southwest, when the region had likely hit its carrying capacity, with continued population growth and limited resources similar to what Thomas Malthus predicted for the industrial world in 1798.

From the mid-1000s to 1280—by which time all the farmers had left—evidence indicates that conflicts raged across the northern Southwest, but birth rates remained high.

“They didn’t slow down—birth rates were expanding right up to the depopulation,” said Kohler. “Why not limit growth? Maybe groups needed to be big to protect their villages and fields.”

“It was a trap,” said Kohler. “A Malthusian trap but also a violence trap.”

The northern Southwest had as many as 40,000 people in the mid-1200s, but within 30 years it was empty. Kohler hypothesizes that the population may have become too large to be sustained as climates deteriorated, and the lower population would not have adequately maintained the social unity needed for defense and new infrastructure.

But whatever the reason, he said, the experience of the ancient Puebloans could suggest that “population growth has its consequences.”

The paper is published in the Proceedings of the National Academy of Sciences as “Long and spatially variable Neolithic Demographic Transition in the North American Southwest,” by Timothy A. Kohler and Kelsey M. Reese.

Researchers continue to make progress in their efforts to understand an essential aspect of prehistoric lifeways and a major contributing factor in the dynamics of human evolution — the human diet. In two studies, one focusing on an archaeological site in Spain, the other in the Turkana Basin in Africa, scientists are suggesting that early humans had a more diverse diet than traditionally thought.

In the first study, published June 25 in the open access journal PLOS ONE, Ainara Sistiaga from the Massachusetts Institute of Technology and University of La Laguna and colleagues examine human fecal matter (poop) detected in sediment samples taken from different occupational floor levels at the site of El Salt in Spain, a site known to have been inhabited by Neanderthals 50,000 years ago. The fecal matter indicated, based on the analysis of fecal biomarkers, that these Neanderthals predominantly consumed meat, consistent with the widely accepted dietary model for Neanderthals, but that they also consumed plant foods. One of the fecal biomarkers was formed by the bacterial reduction of cholesterol in the gut (coprostanol), an indicator of meat consumption, but the other showed the presence of a compound found in plant sources, evidence of significant plant intake.

“Taken together, these data suggest that the Neanderthals from El Salt consumed both meat and vegetables, in agreement with recent hypotheses based on indirect evidence,” conclude Sistiaga and colleagues in the study. “Future studies in Middle Palaeolithic sites using the fecal biomarker approach will help clarify the nature, role and proportion of the plant component in the Neanderthal diet, and allow us to assess whether our results reflect occasional consumption or can be representative of their staple diet.”*

In another study, to be published soon in the Journal of Human Evolution, scientists have found that aquatic fauna (fish and other water-based animals) may have been a highly nutritious source of food for early Pleistocene humans living in the Turkana Basin of East Africa almost 2 million years ago. In this case, Will Archer of the Max Planck Institute for Evolutionary Anthropology and colleagues employed multiple datasets to examine aquatic resource use in the early Pleistocene by focusing on four components of aquatic faunal assemblages: taxonomic diversity; skeletal element proportions; bone fragmentation; and bone surface modification from tool use. These components were used to identify associations between early Pleistocene aquatic remains and hominin behavior at the site of FwJj20 in the Koobi Fora Formation of the Turkana Basin in Kenya. The researchers focused on two dominant aquatic species: catfish and turtles.

Based on their findings, the researchers suggest that aquatic food sources provided hominins (early humans) with a significant alternative or supplement to other, terrestrial food sources. They also suggest that aquatic food sources provided some important advantages, such as “(1) a probable reduction in required investment of energy relative to economic return in the form of nutritionally dense food items, (2) a decrease in the technological costs of resource acquisition, and (3) a reduced level of inter-specific competition associated with carcass access and an associated reduction of predation risk relative to terrestrial sources of food.”**

The Turkana Basin, which includes Lake Turkana and the Koobi Fora (ridge) Formation, is well known in human evolution studies as one of the richest and most important sources of hominin fossils shedding light on the evolution of man over the past 4.2 million years.

Archaeologists are now onsite at Tel Megiddo, in northern Israel, to continue large-scale excavations at what has often been called the “crown jewel” of archaeological sites of the Levant, or Eastern Mediterranean region.

Led by well-known archaeologists Israel Finkelstein of Tel Aviv University and Eric Cline of the George Washington University, a team of archaeologists, students, volunteers and other specialists will be excavating where they left off in 2012, when they encountered a large building featuring 18 pillars dated to the Iron Age IIA period, (around 1000 BCE).  South of the building they uncovered a hoard of six iron daggers and two bronze bowls, dating to the Iron Age I (1200 – 1000 BCE).

Tel Megiddo, a World Heritage site, is best known for the remains of a large Canaanite center that once ruled at a location strategically placed at one of the most important military and trade routes in the ancient Near East, the Via Maris, dominating trade and commercial traffic for over 6,000 years beginning around 7000 BCE. The city is often mentioned in ancient literature and documents such as the Hebrew Bible and the el-Amarna letters of ancient Egypt, particularly as the site of epic battles that changed the course of ancient history in the region. As the inspiration for James Michener’s novel, The Source, the site affords a layer-cake of remains of ancient civilizations that came and went at the location, each succeeding civilization building upon the ruins of predecessors. This has created a treasure for archaeologists and their sponsors, who for decades have been unearthing monumental temples, palace complexes, massive fortifications, and sophisticated water systems, adding to our understanding of Bronze Age and Iron Age settlement and lifeways in the Levant. Some of the major finds of recent seasons have included a hoard of gold, silver and bronze jewelry, all wrapped in fabric and hidden in a vessel dated to around 1100 B.C.; and an Early Christian prayer hall with a mosaic floor discovered at a prison site near the Tel.

For the 2014 season, archaeologists will continue work on the pillared structure exposed in 2012; expose some late Middle Bronze Age (1800 – 1540 BCE) domestic architecture; continue to excavate parts of the early Middle Bronze Age fortification system which includes a massive mudbrick wall and glacis (defensive slope construction); study areas related to Late Bronze-Iron Age street levels; expose more of the Late Bronze Age levels excavated previously; and conduct exploratory soundings in three new locations.

The Tel Megiddo Expedition offers one of the best field school and excavation experiences for students and volunteers in the Levant. More information about the Expedition and the field school can be obtained at their website.

The recent recovery and analysis of 17 early human fossil skulls from the Sima de los Huesos (“Pit of Bones”) cave pit site in the Sierra de Atapuerca cave system of northern Spain have illuminated our understanding of how Neandertals, a more ancient, extinct sister species of Homo sapiens (modern humans), actually evolved, according to a study report published this week in Science.

Currently led by Juan Luis Arsuaga of the Universidad Complutense de Madrid, Spain, archaeological teams have been excavating at the site for four decades, and have recovered the largest assemblage of early human fossils ever discovered at any one site in the world. 

“After thirty years, we have recovered nearly 7,000 human fossils corresponding to all skeletal regions of at least 28 individuals,” says study co-author Ignacio Martinez, Professor of Paleontology at the University of Alcalá. “This extraordinary collection includes 17 fragmentary skulls, many of which are very complete.”

The 17 skulls, according to the researchers, represent a single population of a hominin (early human) species. Although some of have been studied before, seven are presented anew here, and six are more complete than ever before, after many hours of painstaking assemblage in the lab. Now, with the mostly intact samples for study, the researchers have been able to more clearly define the common features of what they believe to be a single population.

The fossils exhibited a mosaic of physical characteristics that could not be wholly attributed to any single, recognized human species to date. The skull samples showed clear Neandertal features in the face and teeth. The researchers suggest these ‘Neandertal-derived’ features were functionally related to mastication, or chewing. “It seems these modifications had to do with an intensive use of the frontal teeth,” Arsuaga said. “The incisors show a great wear as if they had been used as a ‘third hand,” typical of Neanderthals.” But elsewhere, the skulls showed characteristics that diverted from the Neandertal model. The braincase itself, for example, still showed features associated with more primitive hominins.

Observations like these led the researchers to suggest support for the ‘accretion model’ of Neandertal evolution, or something similar to cladogenesis, wherein evolution takes place through a splitting of species into branches or “clades”, leading to the development of a greater variety of sister species.

However, according to Arsuaga,”we think based on the morphology that the Sima people were part of the Neanderthal clade, although not necessarily direct ancestors to the classic Neanderthals.”

“One thing that surprised me about the skulls we analyzed,” Arsuaga continued, “is how similar the different individuals were. The other fossils of the same geological period are different and don’t fit in the Sima pattern. This means that there was a lot of diversity among different populations in the Middle Pleistocene.”

In other words, because other European Middle Pleistocene fossil specimens found in Europe do not exhibit the suite of features seen in this fossil group, the researchers suggest that more than one evolutionary lineage appears to have coexisted during the European Middle Pleistocene, with that represented by the Sima sample being closer to the Neandertals. The work of Arsuaga et al. suggests that facial modification was the first step in Neandertal evolution, a mosaic pattern fitting the prediction of the accretion model.

Key to the study findings was the homogeneity of the Sima samples. “All of the individuals recovered at the site represent the same biological population which makes it possible for anthropologists to study individual variation as well as sexual differences in the skeleton and patterns of growth and development, among other aspects,” report Arsuaga, et al. in a press release of the Centro Mixto UCM-ISCIII de Evolución y Comportamiento Humano. “While considerable differences in size are apparent within the collection, with some larger skulls and some smaller ones, the anatomical features that anthropologists study to examine evolutionary relationships do not vary much within the Sima population. This combination of mosaic evolution and anatomical homogeneity led the authors to favor a branching pattern of evolution, known as cladogenesis in evolutionary studies, in the European Middle Pleistocene.”

So what species do these Sima fossils represent? The study authors do not assign the fossils to any specific species. But mitochondrial DNA was recently extracted and analyzed from one of the Sima fossils. The results suggest that this population was not a group of “early Neandertals”. Nor, as has been previously suggested, were they representatives of another early human species called Homo heidelbergensis, thought to be ancestral to the Neandertals. The Sima jawbones (mandibles) were observed to be anatomically distinct from that of heidelbergensis. 

But there is much more to come from the Pit of Bones.

“With excavations continuing and new fossils being discovered each field season,” report Arsuaga, et al., “there is certainly reason to believe that the Sima de los Huesos will yield more surprising findings in the future.”

A detailed feature article about the work and latest findings at Sima de los Huesos will be published in the upcoming September 2014 issue of Popular Archaeology Magazine.

Remains of Plague Victims Discovered at Thebes in Egypt

Archaeologists have unearthed the remains of third-century plague victims at the Funerary Complex of Harwa and Akhimenru of ancient Thebes.  Live Science

Teams of archaeologists, students and volunteers will return this month to the site of ancient Jaffa on the central coast of Israel to pick up where they left off in 2013, when they uncovered more of the sensational evidence of a fiery destruction at the site’s ancient Amarna period New Kingdom Egyptian fortress gate. The continuing investigations will also include new elements — the search for the ancient harbor complex, and excavation of evidence of a 14th century B.C. destruction layer at the remains of the site’s Lion Temple. 

Under the direction of project co-directors Aaron Burke, Associate Professor of the Archaeology of Ancient Israel at the University of California, Los Angeles, and Martin Peilstöcker of the Isral Antiquities Authority, one team will continue the excavations at the famous fourteenth century B.C. Egyptian fortress gate complex, where in 2013 they uncovered the stark remains of an extensive violent destruction.

Excavations in 2012 first revealed the evidence, with clues to its extent indicated when excavators discovered a commemorative scarab of Amenhotep III dated to the mid-fourteenth century B.C., found within the upper destruction layers and apparently fallen from what the archaeologists interpreted as a second story administrative office floor. A year later, in 2013, they exposed the city gate’s passageway below more than 1.5 meters of destruction debris. The finds included arrowheads, a spearhead and lead weight, decorative ivory inlays, numerous charred seeds, a number of ceramic vessels, antlers from deer, and nearly two dozen cedar timbers thought to have once made up the gate’s roof and upper story. The seeds, identified as those of barley, olive pits, grape pips, and chick peas were a welcome find, as they provide an insight to the foods consumed at the site.

The assortment of artifacts paint a picture of a city gate that functioned as something more than purely a defensive structure — a complex that housed administrators, storerooms, and other support facilities. Speaking of the antlers, for example, Burke and Peilstöcker noted that they “suggest that the gate was not a stark and utilitarian space as many reconstructions of Egyptian gates suggest. Instead, it would seem that Egyptian soldiers hung these items within the passageway as trophies of their hunting around Jaffa.”**

The timbers, the earliest and largest such ancient timbers from that time period found in Israel to date, are thought to have been used in the construction of the gate’s second story and roof. Reported Burke and Peilstöcker in a press release: “They will provide not only important chronological data such as evidence for the date of the construction of the gate complex but also will contribute to refining our understanding of the evolution of Egyptian rule in Canaan since the gate is one in a sequence of gates providing evidence for the earliest Egyptian fortress in Canaan. As important proxies for climate change, the timbers also offer a unique opportunity for an improved study of the Late Bronze Age environment.”**

Burke and Peilstöcker hope to shed light on the nature of coexistence between the Egyptian occupiers and the native Canaanite inhabitants of the area. “New archaeological data combined with well-known historical texts of the Late Bronze Age are now shedding light on the nature of interactions between the Canaanite inhabitants of Jaffa and its environs and the Egyptian inhabitants of the New Kingdom fortress built atop the city’s earlier remains,” reports Burke and Peilstöcker. “The resulting picture is one colored by episodes of violence and peaceful social interactions in Jaffa over a period of more than 300 years, from ca. 1460 to 1130 BC.”*

The city of Jaffa has been an important port city for over 4,000 years. By the Late Bronze Age, Jaffa had become a principal port and garrison for the New Kingdom Egyptian empire. Mentioned four times in the Hebrew Bible, it was named as one of the cities given to the Hebrew Tribe of Dan (Book of Joshua 19:46), as a port-of-entry for the cedars of Lebanon for Solomon’s Temple (2 Chronicles 2:16), as the place from which the prophet Jonah embarked for Tarshish (Book of Jonah 1:3) and as the port-of-entry for the cedars of Lebanon that were used in the construction of the Second Temple of Jerusalem (Book of Ezra 3:7). The city is also mentioned in the ancient Egyptian Amarna letters.

Additional investigation at the site will entail excavation in the area of the “Lion Temple”, a structure thought to exhibit characteristics of a sacred or religious nature. The structure acquired its name from the discovery of a lion skull in its southeastern corner by Jacob Kaplan during his excavations there in the early 1970’s. It is thought to be a Caananite building.

The 2014 season will also see exploratory efforts under Shelley Wachsmann of Texas A&M University, whose team will be investigating the area thought to contain the remains of the ancient harbor of Jaffa. The team will use remote-sensing in a deep-water survey for ancient shipwrecks, testing the application of archaeogeophysical and geoarchaeological techniques to identify the ancient harbor. The investigation will also employ a Remotely Operated Vehicle (ROV) to verify anomalies at the 50 to 300 meter depth range that were previously detected.

More information about the Jaffa project can be obtained at the Jaffa Cultural Heritage Project website, and a detailed article about the Jaffa excavations was published in the March 2013 issue of Popular Archaeology.

“The weather made me do it,” as the saying might have gone for many, long-deceased and unnamed ancient Peruvians. Like some other populations throughout history, they were refugees of climate change who then flourished in their newly found home.

This is the story told by a recent genetic study that suggests that the evidence indicates periods of migration in pre-Columbian Andean societies in Peru, spurred on by local climate changes. It supports the archaeologists, who for years have been saying that the excavated evidence hints of such shifts by the Nasca, Wari and Tiwanaku peoples.

To get to this conclusion, anthropologist Lars Fehren-Schmitz and colleagues collected samples of mitochondrial DNA from 207 individuals in Peru’s Rio Grande de Nasca region and determined that the mitochondrial DNA likely represented Andean populations living between approximately 840 BC and 1450 AD. Using a Bayesian modeling approach, the authors found that the genetic results suggest a migration from the coastal valleys of Southern Peru to the Andean highlands during a period of increasing climate variability around 640 AD. They also found a possible backward migration from the highlands to the coast during a period of drought in the highlands and favorable conditions at the coast around 1200 AD. The study results suggest that climate-driven migrations may have led to a genetic homogenization in Southern Peru over time. 

“The supported migration events coincide with observed climatic alterations, which must have led to a genetic homogenization in the RGND [Rio Grande de Nasca drainage area in southern coastal Peru] over time,” report Fehren-Schmitz and colleagues in the published study. “Most studies analyzing the impact of climate on the mobility and demography of ancient populations have concentrated on foraging societies. Here we reveal climatic impacts on socially complex, agricultural societies. Despite a range of anticipatory agricultural adaptations observed in the archaeological record, the instability of the coastal and highland ecosystems in southern Peru exceeded critical points in the past in which migration became inevitable to sustain the population.”*

The detailed study report is published in the Proceedings of the National Academy of Sciences (PNAS).

Beginning the fourth year of a five-year program of investigation, a team of archaeologists, students and volunteers commissioned by the Senhouse Museum Trust have returned to a site near the Maryport Roman fort in the U.K. to continue excavation of the remains of a Roman temple and associated structures and features.

Led by Newcastle University’s Professor Ian Haynes and site director Tony Wilmott, they hope to recover more of the structural remains and artifacts at a site that had undergone investigation in previous years, yielding some intriguing results.

“This year we will be looking at the eastern edge of the [Maryport] settlement, to the north east of the fort, where at least one temple stood,” said Haynes. “This structure was originally excavated in the 1880s, and we re-examined it last year. 

“Immediately under this building we found the remains of a burnt lamb and bird bones. At other sites across Britain and in other countries these have signified a ritual dedication or offering for the building.

“We also found evidence of a mysterious circular structure next to the rectangular temple and we’re going to be investigating this area to find out what this might have been built for – maybe it was another temple, or a mausoleum.” 

Haynes hopes that investigation of this site will help shed additional light on the meaning and importance of stone military altars from the Roman fort of Alauna Carvetiorum and its associated civilian settlement located at what is now Maryport. 

“The Temples project is designed to learn more about the internationally famous altars which form the core of the Senhouse Roman Museum display and to understand better the complex religious landscape of Roman Maryport,” said Haynes.

“The collection of altars in the museum is really remarkable. The inscriptions provide information on the lives of the commanders of the fort and their postings across the Roman Empire. 

“We want to find out more about exactly where and how they were originally displayed here in Roman times, and how people living in the fort and settlement used rituals such as dedications and offerings.” 

Nigel Mills, heritage advisor to the Hadrian’s Wall Trust, said: “The Roman fort and nearby civilian settlement at Maryport were a significant element of the coastal defenses lining the north western boundary of the Roman Empire for more than 300 years.

“Both the Temples project and the Settlement project show there is huge potential to attract more visitors to the Roman Cumbrian coastal defenses which, along with Hadrian’s Wall, are part of the transnational Frontiers of the Roman Empire World Heritage Site.”

The fort built at Maryport was ordered by Hadrian for construction in the second century AD. It served as the command headquarters and supply base for a series of small forts and towers that extended southward along the west coast from Hadrian’s Wall. The Roman fort and civilian settlement at Maryport are part of the Frontiers of the Roman Empire World Heritage Site, which includes Hadrian’s Wall and its attendant forts. The FRE WHS represents the borderline of the Roman Empire at its furthest extent in the 2nd century AD. It stretched from the west coast of northern Britain, through Europe to the Black Sea, and from there to the Red Sea and across North Africa to the Atlantic coast.

scientists have reported a study that suggests that all human males can trace their roots to an ancestor with violent tendencies — a hominin who was not a gentle, ‘noble savage’ whose descendents were later corrupted or changed by the onset of society, as depicted or suggested by many theorists.

University of Utah biologist David Carrier and Michael H. Morgan, a University of Utah physician, have been conducting a comprehensive study of the human fossil record, including that of Australopithecus, an extinct hominin species that is thought to be ancestral to Homo (the human genus of which Homo sapiens, or the modern human, is the soul surviving species). What they have consistently found, among other things, is that certain bones of the face of the male skull have become increasingly more robust over several million years of evolution, and that these bones were critical for protection against impact from objects — like a human fist, which, they maintain, has also evolved over time to form a more effective fist for striking.

“The australopiths were characterized by a suite of traits that may have improved fighting ability, including hand proportions that allow formation of a fist; effectively turning the delicate musculoskeletal system of the hand into a club effective for striking,” said Carrier.  “If indeed the evolution of our hand proportions were associated with selection for fighting behavior you might expect the primary target, the face, to have undergone evolution to better protect it from injury when punched.”

Their study of the bones of the face and cranium supported that hunch.

“When modern humans fight hand-to-hand the face is usually the primary target,” said Carrier. “What we found was that the bones that suffer the highest rates of fracture in fights are the same parts of the skull that exhibited the greatest increase in robusticity during the evolution of basal hominins. These bones are also the parts of the skull that show the greatest difference between males and females in both australopiths and humans. In other words, male and female faces are different because the parts of the skull that break in fights are bigger in males. Importantly, these facial features appear in the fossil record at approximately the same time that our ancestors evolved hand proportions that allow the formation of a fist. Together these observations suggest that many of the facial features that characterize early hominins may have evolved to protect the face from injury during fighting with fists.”

The findings may have important implications for understanding human nature, and will no doubt become part of the general debate about human evolution.

“The debate over whether or not there is a dark side to human nature goes back to the French philosopher Rousseau who argued that before civilization humans were noble savages; that civilization actually corrupted humans and made us more violent,” said Carrier. “This idea remains strong in the social sciences and in recent decades has been supported by a handful of outspoken evolutionary biologists and anthropologists. Many other evolutionary biologists, however, find evidence that our distant past was not peaceful.”

“The hypothesis that our early ancestors were aggressive could be falsified if we found that the anatomical characters that distinguish us from other primates did not improve fighting ability. What our research has been showing is that many of the anatomical characters of great apes and our ancestors, the early hominins (such as bipedal posture, the proportions of our hands and the shape of our faces) do, in fact, improve fighting performance.” 

The theory that humans evolved from a violent ancestor is actually a long-standing and contentious one. It was Raymond Dart, South African anatomist and discoverer of the famous fossilized ‘Taung child’ Australopithecus skull in 1924, who advanced the theory that humans evolved from a “killer ape”, supporting the hypothesis that war and interpersonal aggression was the driving force behind human evolution. The writer Robert Ardrey, author of African Genesis and The Territorial Imperative, further popularized the theory through his books during the 1960’s. But the notion has encountered stiff resistance or dispute among other scholars and anthropologists over the years, whose research has indicated that this is not necessarily the case.  

Carrier and Morgan make it clear, however, that their study results are not about casting humans as a hopelessly violent and destructive species.

“Our research is about peace,” said Morgan. “We seek to explore, understand, and confront humankind’s violent and aggressive tendencies. Peace begins with ourselves and is ultimately achieved through disciplined self-analysis and an understanding of where we’ve come from as a species. Through our research we hope to look [at] ourselves in the mirror and begin the difficult work of changing ourselves for the better.”

Their paper, titled “Protective buttressing of the hominin face,” is published in the journal Biological Reviews.

A DNA study suggests that early Neolithic people may have migrated into Europe about 9,000 years ago by island-hopping from Anatolia across the Mediterranean through the Dodecanese islands and Crete and across southern coastal routes.

Preistera Paschou and colleagues came to this conclusion after analyzing single nucleotide polymorphisms from a sample dataset of 32 populations, taken from the islands of Crete and the Dodecanese, Central Anatolia, Greece, Southern and Northern Europe, the Near East, and North Africa. They used a population genetics network approach that thye say determines the pathway of gene flow between populations.

Anthropologists and other scientists studying early Neolithic population migration have proposed three general routes that these early peoples may have taken to enter Europe. One was land-based to North-Eastern Anatolia and then through Bosporus and the Dardanelles and Thrace and into the Balkans; the second was maritime, from the Aegean Anatolian coast and across northern Mediterranean islands and along the coast of Southern Europe; and the third from the Levantine coastline across to the Aegean islands and into Greece. It is the second model that the recent genetic study most supports.

“Our data support the Anatolian rather than the Levantine route because they consistently show the Aegean islands to be connected to the Near East through Anatolia,” write Paschou and colleagues in the research report*.

Genetics is not the only evidencial support cited for a maritime model. Archaeology has played its role. “Navigation across the Mediterranean was active during the Early Neolithic and Upper Paleolithic, as illustrated by the finding of obsidian from the island of Milos in Paleolithic sites of the Greek mainland and the early colonization of Sardinia, Corsica, and Cyprus,” add the authors………….”Archaeological evidence from Greek and Near Eastern and Anatolian Neolithic sites suggests that multiple waves of Neolithic migrants reached Greece and Southern Europe. Most likely multiple routes were used in these migrations but, as our data show, the maritime route and island hopping was prominent.”*

The detailed report is published in the Proceedings of the National Academy of Sciences (PNAS).

Archaeologists with the Jamestown Rediscovery Project are now exhibiting a representative sampling of the thousands of Native American artifacts they have uncovered over the past 20 years in or near the site of the 1607 James Fort remains on Jamestown Island, the site of the first successful English colony in North America.

Under the rubric, “The World of Pocahontas Unearthed”, the artifacts can now be seen artfully displayed in their own section within the relatively new Voorhees Archaearium, a large one-story copper-sheathed building that rests on pilings designed to protect the seventeenth century-archaeological features and artifacts that lie beneath.

“Over the past 20 years we have found thousands and thousands of Virginia Indian artifacts in the excavations………many of them date to the contact period which is, for us, about 1607 to about 1610. So for years, we have had a very elegant museum talking about the English equation or the English side of the story, and clearly there is another half — and that’s the indigenous, the Virginia Indian folks who were here,” says David Givens, a senior staff archaeologist with the Jamestown Rediscovery Project.

Artifacts exhibited include flaked stone projectile points, some of which were made of non-local materials and likely used for cultural exchange, as opposed to hunting and fighting purposes; Indian beads; examples of the 48,000 Indian pottery sherds thus far excavated; clay tobacco pipes that served as models for the English equivalent tobacco pipes; and even one clay pot that features an imprinted pattern of fiber from an Indian basket. 

“So when you come to see the exhibit, you can actually ‘see’ a Virginia Indian basket for the first time in over 400 years,” said Givens.

The James Fort site is unique in that it is considered to contain the richest recovered trove of Virginia Native American artifacts in the Chesapeake region, despite the fact that it is primarily an early English colonial site. This is because centuries of mechanized agriculture have disturbed or destroyed most of the Native American village footprints in the ground, while later colonial structures survived as they were set deeper into the soil than those, for example, of the Powhatan villages in the vicinity of the Jamestown settlement.

The Powhatan was a powerful Native American confederation of tribes in present-day Virginia when the Jamestown settlers first arrived. The confederation was led by Chief Powhatan, who was also referred to as “Emperor”. It is thought that there were possibly about 14,000–21,000 Powhatan people in the eastern part of Virginia in 1607 when the English first established James Fort. It was Chief Powhatan’s daughter, Pocahontas, who saved Captain John Smith’s life and later married colonist John Rolf. She bacame a symbol of the relationship that developed between the English Crown and the Native American people of southeastern Virginia.

“The World of Pocahontas Unearthed” can be seen at the Voorhees Archaearium on the grounds of Jamestown Island, not far from the restored colonial town of Williamsburg, Virginia, another major historical site. See the Jamestown Rediscovery website for more information about this and the ongoing excavations and programs related to James Fort and Jamestown.
