Lucy’s discovery transformed our understanding of human origins. Don Johanson, who unearthed the Australopithecus afarensis remains in 1974, recalls the moment he found the iconic fossil.
A bipedal hominin, Lucy stood about three and a half feet tall; her bipedalism supported Raymond Dart's theory that australopithecines walked upright. The whole team including Johanson concluded from Lucy's rib that she ate a plant-based diet and from her curved finger bones that she was probably still at home in trees.
Heidelberg Man: Probably ancestral to Homo sapiens & Homo neanderthalensis. Homo habilis (described in 1964) has features intermediate between Australopithecus and Homo erectus, and its classification in Homo rather than Australopithecus has been questioned.

Likewise, later Homo could reduce relative pelvic inlet size probably due to the elongation of the legs. Pelvic inlet size may not have been due to fetal head size (which would have increased birth canal and thus pelvic inlet width) as an A. afarensis newborn would have had a similar or smaller head size compared to that of a newborn chimpanzee.
Homo erectus is the most long-lived species of Homo, having survived for almost two million years. By contrast, Homo sapiens emerged about a third of a million years ago. Regarding many archaic humans , there is no definite consensus as to whether they should be classified as subspecies of H. erectus or H. sapiens or as separate species.
Since then, the Leakey family has continued to excavate the gorge, uncovering further evidence for australopithecines, as well as for Homo habilis and Homo erectus. [17] The scientific community took 20 more years to widely accept Australopithecus as a member of the human family tree.
