Perhaps the most profound advance in primate evolution occurred about 6 million years ago when our ancestors started walking on two legs. The gradual shift to bipedal locomotion is thought to have ...

The feet of primates function as grasping organs. But the adoption of bipedal locomotion – which reduces the ability to grasp – was a critical step in human evolution. Co-author Carrie S. Mongle, a ...

March 17 (UPI) --New research by anthropologists at Stony Brook University and the University of Texas at Austin confirm the human skull and bipedalism co-evolved. Scientists have previously linked ...
