Not really up on all the "science" but could someone show me what was right before modern Humans and in between Homo Eructus (or whatever the species before Humans were) or did the mutation or change or whatever just happen? I happen to think evolution either happens much quicker and in giant leaps or it doesn't happen at all and something else must explain it (and no- that doesn't mean a God in ths Sky or green men from outer space.)
I've always had problems telling H. erectus apart from H. sapiens archaic. Except for the brain size - 850cc for erectus vs. 1250cc for sapiens...
The point is, the transitions at this point look very gradual to me, as along a continuum.
