The way I like to phrase it is, "if race is genetic, then black isn't a race."<p>As the article says, human genetic difference is very real, and is clustered. Can we not then call these clusters races?<p>There is more genetic diversity within the Africa than in the rest of the world combined. If white and Asian are genetic races, then there are hundreds of different African races. If black is a genetic race then a better name for it is Homo Sapiens -- we're all black.<p>If black is a race and Europeans aren't black, then race isn't genetic, it's cultural.
