The ancient remains of the Australopithecus afarensis were discovered in Ethiopia in 1974. The find was, at the time, the most complete ever found, and revolutionized the understanding of humanity's ancestors.

In a 2016 study, researchers said Lucy had strong upper arms, suggesting she regularly climbed trees and nested in branches at night.

She also had relatively weak legs that were not used for climbing and were inefficient for walking, the study concluded.

An analysis of a fracture on one of Lucy's bones in the same year suggested that she probably died from a fall from a tall tree.

Long considered the longest living human relative, Lucy was dethroned of her status in 1994 following the discovery -— also in Ethiopia -— of Ardi, a female Ardipithecus ramidus who lived 4.5 million years ago.
