Lecture 17 - nov 28 evolutionary genomics of human brain. We are well adapted to behaviorally navigate a social environment (not just physical one) One approach to understanding the esse(cid:374)(cid:272)e of hu(cid:373)a(cid:374)it(cid:455) is the(cid:396)efo(cid:396)e to stud(cid:455) the (cid:862)so(cid:272)ial (cid:271)(cid:396)ai(cid:374)(cid:863) that is, our capacity for mentalistic cognition. Evolved to deceive, cooperate, get along and avoid conflict, manipulate, lots of social functions that require brain power.

Evolved in society (social) that promotes having a big brain. Neocortex size is positively correlated with social group size across primates. Plot measure of brain size and social network size positive correlation. Brain size is functionally associated with social function. Consider the evolutionary genetics of two social brain disorders. Relate to functioning of social brain: diametrically opposite to eachother.
