If I told you people with phone number that end in an odd number have higher IQs than people with even phone numbers, you would ask me how that could possibily be. There is no connection between phone number and genetics.

There is also no connection between the few external features we associate with race-- skin color, eye shape, nose shape, hair texture-- and membership in a gene pool or a population. The genetic diversity of sub-sahara Africa is the same as the genetic diversity of the rest of the world combined.

In other words, the people living in an isolated village in Ghana and the people living in an isolated village in Malawi have no more connection to one another (based on analysis of their mitocondrial DNA) than a group of people in Finland and either African group.

If human history and culture had divided people up in categories based on other external features, as it has in the past, then the catagories would be different.

Black Africa is not a genetic population. Black Africa cannot have a lower IQ as a group because it is not a group. It just cannot be. There is no objective way to measure IQ between groups that differ in terms of diet and culture and education and environment.

You have no way to get at intelligence. You have tens of thousands of genetic populations, not 3 or 4. You really should not go around saying something as idiotic as black people have lower IQs. You have a lower IQ if you can't see that.
