Human sexuality seems normal to us, but it is bizarre by the standards of other animals. Diamond arues that our strange sex lives were as crucial to our rise to human status as our large brains. Among the aspects of human sexuality discussed are female menopause, our having sex in private, our often having sex for fum rather than procreation and the expansion of women's breasts even before use in lactation, and the battle of the sexes over parental care. These features might seem too natural to require explaination, but on reflection they prove surprisingly difficult to account for.

About 80 millennia ago, out of one major exodus by migratory human ancestors from Africa—from Eritrea to Yemen (then to India and Australia, and eventually to Europe)—was the entire non-African world in all its racial and cultural diversity ultimately peopled; and to one prehistoric woman in Africa 150,000 years ago, all the peoples of the world can trace their genetic origin. So argues Stephen Oppenheimer in a groundbreaking volume that has stirred heated controversy among authorities in geology, linguistics, archaeology, and anthropology. Thoroughly researched and meticulously reasoned, with dramatic evidence garnered from recent advances in the field of genetics through DNA analysis, The Real Eve traces the evolution of modern humankind out of a common African ancestry—for again and again, Oppenheimer's extensive genealogical research, based on our gender-specific so-called Adam and Eve genes, has led him straight back to Africa. His conclusions have placed him in direct opposition to multiregionalists, who maintain that archaic human populations evolved locally, and have unsettled many long-established anthropological assumptions and cultural prejudices to provide a fresh perspective on the nature of the human destiny that all of us on planet Earth share.
