Is Ardipithecus ramidus bipedal?

Asked by: Nick Ward

Ardipithecus ramidus is a species of australopithecine from the Afar region of Early Pliocene Ethiopia 4.4 million years ago (mya). A. ramidus, unlike modern hominids, has adaptations for both walking on two legs (bipedality) and life in the trees (arboreality).

What kind of a biped was Ardipithecus ramidus?

facultative biped

This species was a facultative biped and stood upright on the ground but could move on all four limbs in trees. Features of the anatomy are extremely primitive. upper canines are shaped like diamonds, rather than the pointed shape seen in African apes, whch is a derived feature shared with Australopithecus afarensis .
