Professor Dennis O'Rourke Co-authors Article in the journal Science
"The genetic prehistory of the New World Arctic"
The study addressed the genetic origins and relationships of the various New World Arctic cultures to each other and to modern-day populations in the region. Nuclear and mitochondrial DNA data unequivocally showed that the Paleo-Eskimos are closer to each other than to any other present-day population. To read more, click here>>

"Kangaroos Win When Aborigines Hunt with Fire: Co-evolution Benefits Australia’s Martu People and Wildlife"
Australia’s Aboriginal Martu people hunt kangaroos and set small grass fires to catch lizards, as they have for at least 2,000 years. The Department of Anthropology's Brian Codding found such man-made disruption boosts kangaroo populations – showing how co-evolution helped marsupials and made Aborigines into unintentional conservationists.
“We have uncovered a framework that allows us to predict when human subsistence practices might be detrimental to the environment and when they might be beneficial,” says Professor Codding. “When subsistence practices have long histories, they are more likely to sustain ecosystem stability,” he says. “But when there are sudden changes to the way people make a living on the land, expect the result to be detrimental to the environment.”
The findings suggest that Australia might want to encourage small-scale burning to bolster wildlife populations in certain areas, Codding says.

Professor Polly Wiessner Elected to Prestigious National Academy of Sciences
On April 29th, the National Academy of Sciences (NAS) announced the election of 84 new members in recognition of their distinguished and continuing achievements in original research. Professor Polly Wiessner from our own Department of Anthropology was among this newest group of members.
Professor Wiessner is well known for her research on exchange networks in Africa's Kalahari Desert and in Papua New Guinea and for her study of warfare and aggression, particularly among the Enga in Papua New Guinea . Professor Wiessner is a frequent public speaker, giving invited talks at Universities and Conferences around the world. She is also a popular instructor at the U of U, where students enjoy her courses on (The Cultures of Africa” and “The Anthropology of Food.”Professor Wiessner’s nomination and election to the Anthropology sub-section of the NAS places her among 83 fellow members (2014). The election of Professor Wiessner brings the total number of NAS members currently in the Department of Anthropology to four. Professor Henry Harpending was elected in 1996, Professor Kristen Hawkes and Professor James O’Connell were elected in 2002 and 2006, respectively. Former NAS members from the Department of Anthropology at the University of Utah include the late Jesse Jennings, the late Julian Steward and Jeremy Sabloff (Santa Fe Institute).The National Academy of Sciences is a private organization of scientists and engineers dedicated to furthering science and using science for the general welfare of society. It was established in 1863 by a congressional act of incorporation signed by Abraham Lincoln that calls on the Academy to act as an official adviser to the federal government, upon request, in any matter of science or technology.

Professor Dennis O’Rourke publishes a perspective on the Bering land bridge and the peopling of the Americas in Science
Genetic and environmental evidence indicates that after the ancestors of Native Americans left Asia, once linked Siberia and Alaska. Archaeological evidence is lacking because it drowned beneath the Bering Sea when sea levels rose.
University of Utah anthropologist Dennis O’Rourke and two colleagues make that argument in the Friday, Feb. 28, issue of the journal Science. They seek to reconcile existing genetic and paleoenvironmental evidence for human habitation on the Bering land bridge – also called Beringia – with an absence of archaeological evidence.
