The newly identified species were older more primitive and much more ape-like than any hominids known before, but already they were bipedal -- certainly the younger one, probably the other as well.

I prefer a timescale more down-to-earth, one that is secular, evolutionary, and unrepentantly anthropocentric: the time since the appearance of bipedal hominids, about 4.5 million years ago; since the ...

How did humans evolve into the big-brained, bipedal ape that we are today? This article examines the fossil evidence of our 6 million year evolution. Darwin's great insight, and the unifying ...

and subsequent fossil finds of much earlier bipedal hominids have confirmed that conclusion. Bipedalism, it seems, was the first step towards becoming human.

The trackway at Site G, fortuitously preserved within layers of volcanic tuff, offers unique evidence of bipedalism in hominids from 3.6 million years ago. Excavated by Mary Leakey in 1978-79, the ...

Energetics cost in Australopithecus was similar to other mammals and birds. The evolution of bipedal gait is a key adaptive feature in hominids,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16 but the running ...
