GW professor reports earlier beginning for human bipedalism

An ancestor to humans could walk upright about 6 million years ago — the earliest estimate for human bipedalism, anthropology professor Brian Richmond told The New York Times on Thursday.

Richmond and William Jungers, a professor at State University of New York at Stony Brook, analyzed a Orrorin tugensis thigh bone found 8 years ago in Kenya and Richmond said the fossil had “convincing evidence to confirm Orrorin’s bipedal adaptations,” according to The Times.
