Sex for pleasure. Evolution of human sexuality

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 species of mammals, experience menopause? And why do men, unlike the vast majority of other males, after impregnating their partner usually stay with her and help raise the children? After all, for what reason does the human penis have an unreasonably large size?
No one will answer all these questions better than Jared Diamond - a well-known expert in the field of physiology and evolutionary biology, the author of widely known popular scientific works, awarded a number of prestigious awards. He explains how the forces of evolution acted on our ancestors, contributing to the development of unique features of their sex life. Wittily and with many original and convincing examples, the author argues that sexuality played as crucial a role in our rise to human status as a large brain and walking upright.
