Gotcha. I'm somewhat involved in the biology field so it seems a bit like the debate of what exactly constitutes a species amongst animals. Grizzly bears and polar bears create fertile offspring but are clearly different animals, being the easiest example. Thanks for the info. Early humans is one of the most interesting fields of study to me, I just can't handle all the mystery and questions we will never have answers to!
