Scientists working in South Africa have unveiled fossils of a human species new to science that they say could be the direct ancestor of our genus, Homo. Discovered in Malapa cave—just 15 kilometers from the sites of Sterkfontein, Swartkrans and Kromdrai, which have yielded a number of important human fossils—the finds comprise two partial skeletons that are nearly 1.95 million years old. The researchers have given them the name Australopithecus sediba.
