Homo Ergaster

This was originally thought to be a variation of Homo Erectus but several important differences have now been identified between the two species. Homo Ergaster is differentiated by having a larger cranial capacity with a more domed skull. The two species are simliar in body size and proportion. This is thought to be the earliest species to have our own nasal characteristics and so may be the earliest species to have a face similar to our own.
