The last common ancester shared by humans and chimpanzees is thought to have lived six millon or more years ago. Though Ardipithecus is not itself this last common ancester, it likely shared many of this ancester's characteristic.For comparison, Ardipithecus is more than a million years older than "Lucy" the partial female skeleton of Australopithecus afarensis. Bipedal by 6million years ago, leg support 6 million years ago, strong knee 4.1 million years ago, mostly bipedal by 4 million years ago, curved spine 2.5 million years ago,hip support 1.95 million years ago, fully bipedal by 1.95 million years ago, long leg 1.89 million years ago. hominids molecular phylogenetics homo - habilis, homo- neanderthalensis, homo- erectus , homo- sapiens.
