Georgia shows off skull thought to rewrite human evolution

What a piece of work is a man HOW many human species roamed Africa when the genus Homo emerged there about 2.4m years ago is a vexed question. Conventional wisdom suggests that there were as many as four—Homo erectus, Homo ergaster, Homo habilis and Homo rudolfensis—and that one of these, Homo erectus, then both spread into Asia and diversified into other species including Homo sapiens. But skulls are rare and often fragmentary, and some researchers think the differences between them, which are used to separate the four alleged species, are actually no greater than differences in morphology between modern Homo sapiens skulls.The specimen pictured below, about 1.8m years old, supports that second point of view. It was found in Dmanisi, in Georgia, by David Lordkipanidze of the Georgian National Museum and his colleagues, who describe its details in this week's Science. Though a long way from Africa, the skull has...
