Homo habilis inhabited eastern, central and south Africa from 2.4 m.y.a. to 1.8 m.y.a. The first discovery of Homo habilis was made in 1960 by Louis Leakey at Olduvai Gorge in Tanzania, Africa. Olduvai Gorge remained an excellent site for Homo habilis specimens. Koobi Fora in northern Kenya also confirmed Homo habilis' separation form the Australopithecines line by delivering its own specimen, a cranium now called KNM-ER 1470. As well as sites at Swartkans and Sterkfontein in South Africa. Another more recent site is that of the lake Baringo region in Kenya dating to 2.4 m.y.a. This date was also confirmed by another find dated at 2.3 m.y.a found in Hadar Ethiopia.
