Article body
- Other studies on human intelligence and social exchange show that the human cognitive architecture "contains specializations for adaptive problems our ancestors faced."

- It is also explained that "most theories of human mental evolution assume that selection favored higher intelligence and larger brains, which should have reduced genetic variance in both. However, adult human intelligence remains highly heritable, and is genetically correlated with brain size. This conflict might be resolved by estimating the coefficient of additive genetic variance (CVA) in human brain size, since CVAs are widely used in evolutionary genetics as indexes of recent selection."
