Gossip columns

摘要

Perhaps it is not surprising that a man who has studied gossip should have a sparkling factoids and preciousrnanecdotes. Evolutionary anthropologist Robin Dunbar's new book is full of such gems. This is an eclectic collection of essays on humanity and evolution with something for everyone.rnDunbar explains, among other things, why monogamists need big brains, why it is worth buying a new suit for an interview, how to interpret an advert in a lonely hearts column, the perils of messing with evolution and, of course, how many friends one person needs (150 as it happens, aka "Dunbar's number").
