New book on race by Nicholas Wade: Professor Ceiling Cat says paws down « Why Evolution Is True

For this Wade offers virtually no evidence, because there is none. We know virtually nothing about the genetic differences (if there are any) in cognition and behavior between human populations. And to explain how natural selection can effect such rapid changes, Wade posits some kind of "multiplier effect," whereby small differences in gene frequencies can ramify up to huge societal differences. There is virtually no evidence for that, either. It is a mountain of speculation teetering on a few pebbles.
