Scientists Find Old Jaw New York (AP) – Scientist have found a 2.4 million-year-old jaw from a close cousin of modern humans outside of the well-known fossil sites of Africa, revealing a new place to seek remains of early human ancestors. The jaw is one of only two known specimens thought to be as old from the evolutionary group called Homo, which includes modern people, homo sapiens. The fossil was found near the western shore of Lake Malawi in the nation of Malawi. The area lies between the well-known sites for fossils of early human predecessors in eastern and southern Africa, The bone belong to Homo rudolfensis, researchers from German, Malawi and Hunter College in New York write in Thursday’s issue of journal Nature. It was found in 1991. Study co-authoer Tim Bromage of Hunter College said Homo rudolfensis may have arisen in Africa’s Rift Valley, which stretches from Ethiopia to Mozambique, partly in reponse to an unusually cool and dry period some 2.5 million years ago.
