This image released by the journal Science shows the right hand skeleton of the adult female Australopithecus sediba against a modern human hand. A detailed analysis of 2 million-year-old bones found in South Africa offers the most powerful case so far in identifying the transitional figure that came before modern humans, findings some are calling a potential game-changer in understanding evolution. The hand, seen in a palmar view, lacks three wrist bones and four terminal phalanges, but is otherwise complete.
