Why are humans radically different from their closest ancestors, the great apes, in many important aspects of sexual life? Why do women, unlike females of almost all other mammalian species, go through menopause? And why do men, unlike the vast majority of other males, usually stay with their mates after fertilising them and help raise their children? Finally, why is the human penis unreasonably large?

No one can answer all these questions better than Jared Diamond, a renowned expert in physiology and evolutionary biology, author of widely read popular science books and recipient of a number of prestigious awards. He explains how the forces of evolution acted on our ancestors, contributing to the development of the unique features of their sex life. With wit and a wealth of original and compelling examples, the author argues that sexuality has played as crucial a role in our rise to human status as a large brain and upright walking.
