Working up a sweat
Dinosaurs were warm-blooded, new study says
Nov. 11,
2009 --
Were dinosaurs "warm-blooded" like present-day mammals and birds, or "cold-blooded" like present day lizards? The implications of this simple-sounding question go beyond deciding whether or not you'd snuggle up to a dinosaur on a cold winter's evening. In a study published this week in the journal PLoS ONE, a team of researchers, including Herman Pontzer, Ph.D., assistant professor of anthropology in Arts & Sciences at Washington University in St. Louis, has found strong evidence that many dinosaur species were probably warm-blooded.

Fishy science
First direct evidence of substantial fish consumption by early modern humans in China
July 9,
2009 -- Freshwater fish are an important part of the diet of many peoples around the world, but it has been unclear when fish became an essential part of the year-round diet for early humans. A new study by an international team of researchers, including Erik Trinkaus, Ph.D., the Mary Tileston Hemenway Professor of Anthropology in Arts & Sciences, shows it may have happened in China as far back as 40,000 years ago.

To watch the 5 o'clock news every night, you'd think man was born to be destructive, violent and antagonistic. But that's just not the case, argue numerous prominent researchers who will gather at Washington University in St. Louis March 12-14 to discuss the nature of human sociality. The conference, titled "Man the Hunted: The Origin and Nature of Human Sociality, Altruism and Well-Being," will be the first of its kind to include academics from around the world and across multiple disciplines — anthropology, psychiatry, human evolution, biology, religion, education and medicine — to focus on the evolution of cooperation, altruism and sociality and possible factors that led to the evolution of these characteristics in primates and humans.

Despite popular theories to the contrary, early humans evolved not as aggressive hunters, but as prey of many predators. "Humans are no more born to be hunters than to be gardeners," argues Robert W. Sussman, Ph.D., professor of anthropology in Arts & Sciences, in the newly-updated version of the controversial book "Man the Hunted: Primates, Predators and Human Evolution."
