Lucy is the common name of AL 288-1, several hundred pieces of bone representing about 40% of the skeleton of a female Australopithecus afarensis. It was discovered in 1974 at Hadar in the Awash Valley of Ethiopia's Afar Depression.
The skeleton shows evidence that Lucy had a small skull capacity, like an ape, but that she walked upright like a human. This supported the view that bipedalism (walking upright) came before increase in brain size in human evolution. Those features are true of all australopithecines.
