About the book For centuries, links between biology and behavior have been mined for ammunition in the gender wars. Western science has often tainted the discussion by skewing the norm toward men so that the biological underpinnings of their weaknesses and strengths are applauded while those of women are denigrated. Sex on the Brain is a chatty, fairly evenhanded report on a broad range of animal and human studies intended to provide insight into hot-button issues such as aggression, nurturing behavior, infidelity, homosexuality, hormonal drives, and sexual signals.
Infidelity is a way for men to ensure genetic immortality.
The answers, the focus of Sex on the Brain, are sometimes solid, occasionally unconvincing, always incomplete. She handles her topics with scrupulous even-handedness, and she's a good reporter. Here she happily plays referee in the battle of the sexes by reporting on the latest biological findings about the myriad differences between men and women. Blum has interviewed the experts and comes up with a number of agreed-upon facts. Top of Page .
