This is an attempt to make a small scale science documentary on human evolution. Human evolution is a dynamic subject which is constantly being updated. Black Ryder Films tried to present timely information.
The latest news is that the anatomy of three new fossils (from Koobi Fora in northern Kenya), including a face, lends support to the hypothesis that there were at least two parallel lineages early in the evolutionary history of our own genus, Homo.
The new fossils confirm the presence of two contemporary species of early Homo, in addition to Homo erectus, in the early Pleistocene of eastern Africa.
