@blackonbuzz: Modern evolutionary genetics leaves little doubt: every human alive today is descended from Africans. Amusingly, this is true for dyed-in-the-wool white-supremacists. The late Guyanese-born Africana Studies professor Ivan Van Sertima (1935-2009) explains how, roughly 55,000 years ago, a small subgroup migrated out of the continent to populate the rest of the globe. This 'Out of Africa' model account for the geographical origin and early migration of modern humans (Homo sapiens). Video credit: For the People, South Carolina ETV, 1995
