Ardipithecus

'Ardipithecus' is a very early Hominini genus which lived about 4.4 million years ago during the early Pliocene.Because this genus shares several traits with the African great ape genera , some consider it to be on the chimpanzee rather than human branch, but most consider it a proto-human because of a likeness in teeth with Australopi...

Description

Key features of this group involve various adaptations for living predominantly on the ground rather than on the trees. In particular, it is vertical standing, moving on two legs and the skull placed on top of the vertebral column. The feet are not adapted to grasping and holding unlike the rest of primates, since the first toe is built robustly and aligned with the other four. The hands have a developed opposable thumb and are quite adept at manipulating objects.
