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 ...

"This question of how bipedalism influences skull anatomy keeps coming up partly because it's difficult to test the various hypotheses if you only focus on primates," Kirk said. "However, when you ...

A new study provides support for the hypothesis that walking on two legs, or bipedalism, evolved because it used less energy than quadrupedal knucklewalking. David Raichlen, an assistant professor of ...

In this video segment adapted from NOVA, see how paleoanthropologists—including Don Johanson, with his famous discovery of the Australopithecus afarensis "Lucy"—have used the fossil record to identify ...

An analysis of wrist anatomy in humans, chimps, bonobos and gorillas indicates our own bipedalism probably did not evolve from a knuckle-walking ancestor. "Our data support the opposite notion, that ...

4.5 million-year old fossil shows evidence of greater reliance on bipedalism than previously suggested The oldest distinguishing feature between humans and our ape cousins is our ability to walk on ...

CHARLES DARWIN suggested that our ancestors first stood upright to free their hands for toolmaking. We now know that cannot be right since the oldest tools yet discovered are a mere 2.6 million years ...

The evolution of bipedalism in fossil humans can be detected using a key feature of the skull -- a claim that was previously contested but now has been further validated by researchers. The evolution ...
