Right, that goes along with what I was saying. The multi-regional theory basically says that those various species of humans, like Erectus, branched off into different groups as they moved out of Africa. Eventually each group evolved into the various sub-groups of homo-sapiens we have today.
Out of Africa, on the other hand, says that homo sapiens didn't evolve from these species. It theorizes modern humans evolved only in Africa, and replaced other groups as they spread across Europe and Asia.
Then again, it's very possible that I'm not quite clear on what the multi-regional theory is saying (discovery channel specials hosted by a Baldwin, and wikipedia only do so much to teach human evolution).
