AUSTIN, Texas — The ancient remains of a teenage girl found in an underwater Mexican cave establish a definitive link between the earliest Americans and modern Native Americans, according to a new study released on May 15, 2014 in the journal Science.
The study was conducted by an international team of researchers from 13 institutions, including Deborah Bolnick, assistant professor of anthropology at The University of Texas at Austin, who analyzed DNA from the remains simultaneously with independent researchers at Washington State University and the University of Illinois at Urbana-Champaign.

Why do the faces of some primates contain so many different colors — black, blue, red, orange and white — that are mixed in all kinds of combinations and often striking patterns while other primate faces are quite plain?
UCLA biologists reported last year on the evolution of 129 primate faces in species from Central and South America. This research team now reports on the faces of 139 Old World African and Asian primate species that have been diversifying over some 25 million years. (more…)
UD student helps provide children in Nigeria a schoolhouse of their own
In the Nigerian village of Ukya’u, the children have a teacher and sit on benches in a church room, but there are no desks, no separate classes and no school building to call their own.
Chelsea Rozanski, a University of Delaware sophomore who is majoring in anthropology with a minor in African Studies, is working to change that situation. (more…)
Egypt’s new democratically elected president Mohamed Morsi recently made world headlines on two accounts. The first was for his central role in brokering a cease-fire in Gaza between Israeli forces and Hamas. The second, which followed almost immediately after the deal was confirmed, was a highly controversial presidential decree that would temporarily insulate his legislative and executive decisions from any judicial oversight. Ian Straughn, visiting assistant professor of anthropology and Joukowsky Family Librarian for Middle East Studies, analyzes the return of protesters to Cairo’s Tahrir Square and the future of the Arab Spring in Egypt.

COLUMBUS, Ohio – A common type of geographic mapping software offers a new way to study human remains.
In a recent issue of the American Journal of Physical Anthropology, researchers describe how they used commercially available mapping software to identify features inside a human foot bone – a new way to study human skeletal variation. (more…)
COLUMBIA, Mo. – Marrying multiple husbands at the same time, or polyandry, creates a safety net for women in some cultures, according to a recent study by a University of Missouri researcher. Extra husbands ensure that women’s children are cared for even if their fathers die or disappear. Although polyandry is taboo and illegal in the United States, certain legal structures, such as child support payments and life insurance, fill the same role for American women that multiple husbands do in other cultures.
“In America, we don’t meet many of the criteria that tend to define polyandrous cultures,” said Kathrine Starkweather, doctoral student in MU’s Department of Anthropology in the College of Arts and Science. “However, some aspects of American life mirror polyandrous societies. Child support payments provide for offspring when one parent is absent. Life insurance allows Americans to provide for dependents in the event of death, just as secondary husbands support a deceased husband’s children in polyandrous societies.” (more…)
Turns out it’s not bad being top dog, or in this case, top baboon.
Results of a study by University of Notre Dame biologist Beth Archie and colleagues from Princeton University and Duke University finds that male baboons that have a high rank within their society recover more quickly from injuries, and are less likely to become ill than other males.
The finding is somewhat surprising, given that top-ranked males also experience high stress, which should suppress immune responses. (more…)
While the disappearance of Neanderthals remains a mystery, paleoanthropologists have an increasing understanding of what allowed their younger cousins, Homo sapiens, to conquer the planet. According to Ariane Burke, Professor in the Department of Anthropology at the Université de Montréal, the rapid dispersal of anatomically modern humans was not so much due to superior intelligence or improved hunting or gathering techniques, but rather to the creation of symbolic objects that allowed them to extend their social relations across vast territories.
Symbolism and social exchanges
Homo sapiens arrived in Europe some 45,000 years ago, from Africa. In less than 15,000 years, they managed to occupy the whole of Europe and Eurasia—an extremely rapid expansion. Neanderthals, on the other hand, were born of Europe, appearing on the continent more than 250,000 years ago, after their ancestors, Homo ergaster, had established there 600,000 years earlier. Though physiologically well adapted to the cold climate of the glacial and postglacial periods, why were Neanderthals not as successful as their newly landed rivals in colonizing the continent?
