The fossilized remains of a jaw and teeth are discovered near the origin of the previous eldest human ancestor, Lucy. This jaw belonged to a species by the name of Australopithecus deyiremeda. This species would have existed between 3.3 and 3.5 million years ago, putting it at an age when Lucy's species Australopithecus afarensis could have walked the Earth. This oldest species is now one of three species that existed in eastern Africa more than 3 million years ago more closely related to humans than to chimps. The third was Kenyanthropus platyops, having lived in Kenya at roughly the same time.
