Ardipithecus remains go back as far as 5.8 million years ago to as young as 4.4 million years ago. On Friday, Science magazine will present 11 papers detailing what we now know about this ancient late Miocene/early Pliocene hominin. It appears to have walked bipedal but with a highly divergent big toe. The only creature that I know of that also walked bipedally in this fashion was the late Miocene hominoid, Oreopithecus bambolii.Read the latest info and watch a fascinating video on Ardipithecus at:
