What did Lucy look like? With a mixture of ape and human features—including long dangling arms but pelvic, spine, foot, and leg bones suited to walking upright—slender Lucy stood three and a half feet (107 centimeters) tall.
How do we know that Lucy was a female?
How do we know Lucy was a female? Johanson hypothesized almost immediately that Lucy was a female because of her small size. He was knowledgeable about fossil hominin discoveries made by other researchers, in other parts of Africa, in decades prior to the Lucy discovery.
A cast of Lucy on display in the Museum's Human Evolution gallery. Her small skull, long arms and conical rib cage are like an ape's, but she has a more human-like spine, pelvis and knee due to walking upright. Johanson thought Lucy was either a small member of the genus Homo or a small australopithecine.
