Wait, one more thing: Tay-Sachs is not a "White" disease: it is within a more or less closed breeding population, Wester European Jews (were closed for a long time). That is a good way to do genetics: by population. Africans are not a closed breeding population. How many Ethiopian Christian Highland-Mali Muslim Lowland marriages do you think there have been in the past 2000 years? One? Maybe one and the service was probably in Washington DC in 1996. And you talek about BASE PAIRS for genes but I said MTDNA. Mitocondrial DNA. You don't even know what I'm talking about and dismiss my points as irrelevant. The genetic diversity of Africa is not irrelevant. If China and Finland and everyone in between are more related than a village in Senegal and Mozimbique, it matters. Evolution since leaving Africa, which is 30,000 years in the case of Europe, is not that long. One group of Africans have been separated from another group of Africans for just as long. There is no reason to think evolution stopped in Africa. What an idiotic reply you made here. I could rip it up further but I have to go take care of my baby, adopted from Ethiopia, you Neaderthal.
