Con todos esos elementos, se confirmo la teoria de que la cuna de la humanidad estaba en Africa, pero tambien se creyo que Lucy o el Australopithecus afarensis era la bifurcacion de los primates y los hominidos, que a partir de esa especie la evolucion conduciria al Homo sapiens, pasando por el Homo habilis y el Homo erectus, en una breve y muy general secuencia.
The research, titled "Human-like hand use in Australopithecus africanus, shows that Australopithecus africanus," a 3-2 million-year-old species from South Africa traditionally considered not to have engaged in habitual tool manufacture, has a human-like trabecular bone pattern in the bones of the thumb and palm (the metacarpals) consistent with forceful opposition of the thumb and fingers typically adopted during tool use.

Two-million-year-old Australopithecus sediba's awkward strut would eventually send a modern man begging for a knee or hip replacement, but scientists are stunned at how evolution equipped her for both climbing trees and walking.
But over three nights this week, Professor Alice Roberts, Dr George McGavin and a team of international experts will take the fragmented remains of ancient bones and rebuild the bodies of three individuals from that period - - a Neanderthal, a Homo Erectus and an Australopithecus Afarensis.
