Answer 1

A member of the species Australopithecus afarensis, which lived from 3.9 million to 2.9 million years ago, Lucy helped answer some key questions. She confirmed that upright walking evolved long before hominids began using stone tools—about 2.6 million years ago—and before their brains began to expand dramatically.
