On 24 November 1974 in the Afar region
of Ethiopia, anthropologists Donald. Johanson and Tom Gray made one of
the most famous fossil discoveries ever.
While out fossil hunting in sandy ravines near the
River Awash, they discovered a 40% complete
skeleton dating to 3.2 million years ago.
They named the find 'Lucy'.
Lucy's species, Australopithecus afarensis, have
small canine teeth compared with apes.
This suggests males may have been cooperating.
Examinations of Lucy's knee joint and pelvis
demonstrate that she walked upright. And
footprints left in volcanic tuff at Laetoli in
Tanzania by afarensis suggest it walked
with a human-like stride.
