I don't think all our ancestors came from Africa. Not sure how the Neanderthals developed but it was northern and people in most of Africa do not have their genes, or so I am told. I think I would have a pretty high Neanderthal gene pool... Irish from western Ireland and Basques are said to have the highest..last I heard. But I would think Siberians etc. would be very high, Laplanders etc...who knows. Everyone get tested.
