Australopithecus afarensis facial features

Description:Australopithecus afarensis has canines and molars relatively larger than in modern humans , a relatively small brain size - to cm3 - and a face with forward projecting jaws. The anatomy of the hands, feet and shoulder joints suggest that the creatures were partly arboreal rather than exclusively bipedal, although in overall anatomy, the pelvis is far more human-like than ape-like. The change in the pelvis would infact have made child birth more difficult. Australopithecus afarensis would have had relatively short legs and long arms. Australopithecus afarensis Museum national d'histoire naturelle, Paris Australopithecus afarensis had replaced the opposable big toe with the arched foot, and was able to walk in almost the same way as modern humans , with a normal erect gait, as suggested by the Laetoli evidence. Australopithecus afarensis in Africa was probably becoming bipedal as a response to a changing climate, changing from a jungle to a savannah environment.
