"Until this find, Lucy's species--Australopithecus afarensis--was considered the only possible human ancestor in the middle Pliocene [3.5 million years ago] era," says legendary fossil hunter Meave Leakey at the National Museums of Kenya: "Now we have two possible candidates." One became extinct; the other kept evolving. "But I don't know which one," Leakey says.
The new skull dates from the same era as Lucy, but belongs to a previously unknown species. Unlike Lucy, who has a protruding ape-like jaw, with big teeth for chewing grasses and roots, the new skull has a flat, humanlike face with small teeth for eating fruits and insects. Leaky named it, Kenyanthropus platyops, meaning "the flat-faced human from Kenya."
