The lactose reflux problem

Stephen J. Gould said that “there’s been no biological change in humans for 40,000 or 50,000 years.” Gregory Cochran and Henry Harpending beg to differ and, in “The 10,000 Year Explosion,” point to evidence for a recent acceleration in human evolution (e.g. lactose intolerance) 1 and blame it on agriculture. Not everyone agrees. I can’t help finding the idea of the end of genetic change somewhat preposterous, a priori. 2 But one must find data. Check out the interview with Cochran at 2blowhards. 3 What all this means to us here, of course, is that when we assess variation in the nutritional value of agrobiodiversity, we need to remember that that value may differ among human individuals and populations.
