I think it's the only, repeat, only compelling theory there is unless you just go for the, 'well it was bound to happen' or 'there were many reasons' option or assume that there are simply massive holes in our understanding of human movements and development (i.e. that we didn't come from Northern Africa, etc.)

I mean, thick skinned dead elephants... it's pretty wafer thin.
