What does Lucy tell us about evolution?
In 1974, Lucy showed that human ancestors were up and walking around long before the earliest stone tools were made or brains got bigger, and subsequent fossil finds of much earlier bipedal hominids have confirmed that conclusion. Bipedalism, it seems, was the first step towards becoming human.

Perhaps the world’s most famous early human ancestor, the 3.2-million-year-old ape “Lucy” was the first Australopithecus afarensis skeleton ever found, though her remains are only about 40 percent complete (photo of Lucy’s bones). Discovered in 1974 by paleontologist Donald C.
How did the Australopithecus afarensis adapt to the environment?
They also had small canine teeth like all other early humans, and a body that stood on two legs and regularly walked upright. Their adaptations for living both in the trees and on the ground helped them survive for almost a million years as climate and environments changed.

Lucy, a 3.2 million-year old fossil skeleton of a human ancestor, was discovered in 1974 in Hadar, Ethiopia. The fossil locality at Hadar where the pieces of Lucy’s skeleton were discovered is known to scientists as Afar Locality 288 (A.L. 288).
