it; how did such a group of people appear if they and humans did not both evolve from a common ancestor?
Homo erectus: has not been displaced by the discovery of ER 1470. Such claims are based on early reports of 1470 which exaggerated its modernness, and on an early erroneous dating of ER 1470 which had been corrected by the late 1970’s. Australopithecus africanus: supposedly disqualified by the discovery of ER 1470 in 1972. As with Homo erectus, this ‘disqualification’ is based on the early erroneous dating of ER 1470 which had been abandoned about 5 years before Fix wrote his book. Homo habilis: ‘ancestral status is still indeterminate’. It’s difficult to determine any relationship between fossils with absolute certainty. But the habiline fossils are in the right time and place, and with the right characteristics, to be very good candidates for human ancestry. Australopithecus afarensis, “Lucy”: ‘beset by many problems and mounting controversy’. Well, it’s been true that there’s been plenty of dispute about the exact mode of Lucy’s locomotion: was she completely bipedal, or partly arbo
