Surely you've wondered why your boyfriend is so invested in football or why your sister is such a gossip. Of course there's lots of social grooming involved, but Joyce F. Benenson's Warriors and Worriers: The Survival of the Sexes ($20) explores the former part of the nature versus nurture argument. We know developmental psychology and evolutionary anthropology may be things you swore you'd never think about again after finals, but if you've burned out on Buzzfeed lists and are looking for a little more stimulating reading, give it a shot.
