Just like I said most africans do have Nubian roots, besides tribes like the Khoisan, and the Twa (so called pygmy). And you are WRONG, there are strong connections. Today, the Nubas of the Nuba Mountains are direct descendants of the ancient Nubians, The Nuer People of Sudan, the Dinkas and a number of "Nilotic" peoples as well as many people in East&West Africa of Bantu linguistic origins are also of Nubian origins. In fact, although it is said that the Bantu ( Ba-Ntu ) migrated from Nigeria to populate the rest of Southern Africa about five thousand years ago, there is a significant of what appears to be close linguistic similarities between some Nilotic and ancient Egyptian and Cushite languages with the Bantu Languages, both of which originated in the Sahara.
