Study Shows Bipedal Humans Came Down From The Trees, Not Up From The Ground

"We have the most robust data I've ever seen on this topic," said Daniel Schmitt, a Duke University associate professor of evolutionary anthropology. "This model should cause everyone to re-evaluate what they've said before."

A report on the findings will appear online during the week of Aug. 10 in the research journal Proceedings of the National Academy of Sciences.
