For years I've been reading the debates about humanity coming from East Africa migrating and populating the rest of the world. From that point we began to see a lot of evidence which suggest that humanity came from South Africa ... but I often would notice that they would be hesitant to do research on West Africa. So now that they are actually and finally doing research in Africa they are finding things that are actually reshaping history. I think this is extremely important especially to our people who many are descendants from West Africa.
