No, Mary Leakey did not find Lucy. Lucy, an Australopithecus afarensis fossil, was discovered in 1974 by paleoanthropologist Donald Johanson and his team in Hadar, Ethiopia.
Mary Leakey was a prominent figure in the field of archaeology and paleoanthropology, best known for her discoveries in Tanzania, including the fossilized footprints of early hominins at Laetoli. While both Mary Leakey and Donald Johanson have made significant contributions to our understanding of human evolution, their key discoveries are distinct and took place in different locations.
Lucy’s discovery was groundbreaking because it provided crucial evidence of bipedalism in early hominins, influencing our understanding of the evolutionary lineage leading to modern humans. In contrast, Mary Leakey’s findings have helped outline the path of early human ancestors and their behaviors.
