This discovery gave us much scientific evidence. Lucy lived about 3.2 million years ago,[2] and is a hominid.

The skeleton shows that Lucy had a small skull capacity, like an ape, but also that she walked upright like a human. This supported the view that bipedalism came before the increase in brain size in human evolution. Those features are true of all australopithecines.[3][4]
