> Ray did you really just want to say the genus homo?  as in Homo erectus.

Yes, prior hominids were very different than those ( Homo) that
appeared at
the beginning of the Pleistocene.  Homo Sapiens first appeared about
400,000
years ago.  All of these Human creatures were evolved to fill a
particular
ecological niche - the ice age.
