Archaic forms of Homo sapiens first appear about 500,000 years ago. The term covers a diverse group of skulls which have features of both Homo erectus and modern humans.

Henry Field, in writing about the possible cradle of Homo Sapiens, gave a very cursory review of the chief finds ... Part of this evidence, curiously enough, is the fact of diversity of physical type found within what appear to have been single families (since the fossils are found all together and seem to be contemporary).

There is some evidence of hybridization between the...
