Most Africans are don't have "great genetic diversity" like you said. The most genetically diverse they get is from a Tuscan to a Swede, and that's only for some select tribes. Most of the tribes in the regions tested showed "little genetic differentiation", as the study itself says.
That isn't what I said, when I said Africans, I was only including Sub-Saharan Africans, and it is a patent fact that the genetic diversity of SSA is quite large. So you're misinterpretation of my post followed by an unhealthy dose of stupidity has been verified. Negged. I'm done with you, I am not having a back-and-forth with someone that is obviously too lazy to read and quite stupid, and hasn't taken time to study English to a competent level. I see my patience waning the older I get. I am not like I was when I was younger where I was more considerate, nowadays if you're dumb, I don't deal with you.
Re-read my posts, try to understand them, then read the links one more time. Specifically focus in on those wikipedia links.
