The emergence of early Homo appears
to be primarily in east Africa. Evidence of a transitional forms similar
to Homo habilis have been found in south Africa and the later Homo
erectus is found in south Africa. The spread of Homo erectus
out of Africa probably tood place at or following 1.0 million years ago.
The sites of Koobi Fora and Olduvai Gorge are significant in terms of the
story of early Homo. Several sites in China and Java also play an
important role after the spread of Homo erectus.
