Ardipithecus kadabba
Ardipithecus ramidus

Ardipithecus is a very early hominid genus, which lived during the late Neogene.

Two species are known: A. kadabba, dated to about 5.6 million years ago (late Miocene),[1] and A. ramidus, which lived about 4.4 million years ago during the early Pliocene.[2]

Because this genus shares several traits with the African great ape genera (Pan and Gorilla), some place it on the that branch rather than human branch.

Most consider it a proto-human because of a likeness in teeth with Australopithecus. Ardipithecus had bipedalism and reduced canines, like the Australopithecines.
