USEFUL: JayMan’s Race, Inheritance, and IQ F.A.Q.
3. There can’t be races or racial differences because everyone knows serious human evolution stopped 50,000 years ago.
Not true. In reality, human evolution has accelerated during that time, especially during the last 10,000 years since the advent of agriculture. A simple look at the distribution of lactose intolerance is enough to disprove the idea that significant human evolution stopped in the distant past . . .
Physicist Gregory Cochran’s and anthropologist Henry Harpending’s 2009 book The 10,000 Year Explosion: How Civilization Accelerated Human Evolution details this. The advent of agriculture and the rise of states both greatly enhanced the rate of human evolution.
