Out of Africa or multiregional

Which hypothesis is correct, leaving aside that the majority of academia chooses the first one for unknown reasons? The limited fossil record seem to match both.

By sub groups, I meant races.  I'm no biologist, so I have no idea what the proper term for that would be.  From what I gather multiregional theorists believe Homo erectus essentially evolved into modern humans in 4 or 5 different ways, which is the reason for the different 'types' of humans we see on each continent.

Obviously that's dumbing it down a good deal, but that's the gist it seems.
