To us humans the sex lives of many animals seem weird. In fact, by comparison with all the other animals, we are the ones with the weird sex lives. How did that come to be?Just count our bizarre ways. We are the only social species to insist on carrying out sex privately. Stranger yet, we have sex at any time, even when the female can't be fertilized (for example, because she is already pregnant, post-menopausal, or between fertile cycles). A human female doesn't know her precise time of fertility and certainly doesn't advertise it to human males by the striking color changes, smells, and sounds used by other female mammals.Why do we differ so radically in these and other important aspects of our sexuality from our closest ancestor, the apes? Why does the human female, virtually alone among mammals go through menopause? Why does the human male stand out as one of the few mammals to stay (often or usually) with the female he impregnates, to help raise the children that he sired? Why is the human penis so unnecessarily large?There is no one better qualified than Jared Diamond—renowned expert in the fields of physiology and evolutionary biology and award-winning author—to explain the evolutionary forces that operated on our ancestors to make us sexually different. With wit and a wealth of fascinating examples, he explains how our sexuality has been as crucial as our large brains and upright posture in our rise to human status.

Review:

Many of us pursue fitness because we want to remain attractive to partners and potential partners, and we stay healthy so we can continue to have sex with those partners. But why do people care so much about sex? This book, written by an evolutionary biologist, explains how all the weird quirks of human sexuality came to be: sex with no intention of procreation, invisible fertility, sex acts pursued in private--all common to us, but very different from most other species. Why Is Sex Fun? asks us to look at ourselves in a brand-new way, and richly rewards us for doing so.
