"From a renowned expert in the field of physiology and author of the Pulitzer Prize-winning book Guns, Germs, and Steel comes a delightfully entertaining and enlightening look at the unique sex lives of humans. Jared Diamond answers such questions as: 'Why are humans one of the few species to have sex in private?' 'Why do humans have sex any day of the month or year-- including with the female is pregnant, beyond her reproductive years, or between her fertile cycles?' 'Why are human females the only mammals to go through menopause?' 'Why is the human penis so unnecessarily large?' 'Why do we differ so radically in these and other important aspects of our sexuality from our closest animal relatives and ancestors?'
There is no more knowledgeable or compelling authority than Diamond to answer these intriguing questions. With with and fascinating scientific expertise, he explores the mystifying evolutionary fores that gave shape to our sexual distinctions and shows how they contributed to what it means to be uniquely human."
