Finding Lucy. Don Johanson describes finding the knee joint in Hadar, Ethiopia, that first indicated a bipedal hominid had lived 3 million years ago. His subsequent expedition led to the discovery of Lucy, a 40 percent complete skeleton of a new species of hominid, now known as Australopithecus afarensis.
