A. afarensis is one of several extinct hominin species that form an early part of the human evolutionary tree. It lived between 3.9 and 2.9 million years ago. The A. afarensis fossil 'Lucy' (1974) was found at the Hadar site in Ethiopia's Afar depression. Animals shown here include elephants and antelopes. For a similar scene, see C015/5361.
