 Other genetic studies show much greater levels of sub-Saharan African ancestry in the current-day populations of southern as opposed to northern Egypt, and anticipate that mummies from Upper (southern) Egypt would contain greater levels of sub-Saharan African ancestry than Lower Egyptian mummies.Some modern scholars such as W. E. B.Du Bois, Chancellor Williams, Cheikh Anta Diop, John G. Jackson, Ivan van Sertima, Martin Bernal and Segun Magbagbeola have supported the theory that the Ancient Egyptian society was mostly Black.
