Sub-Saharian Africans, I call them 'stay-at-home' Africans. Everyone else in the world are more closely related to each other than they are to the Sub-Saharian Africans.
You're right, I should have been more accurate. Sub-Saharan Africans. I wouldn't call them "stay at home," though, since it's pretty hard to ignore black african influences in the New World (the Olmecs and all). They got around, but their voyages were relatively recent.
