Why Is Sex Fun?: The Evolution Of Human Sexuality (6 Hours): This book speculates on the evolutionary forces that shaped the unique aspects of human sexuality: female menopause, males' role in society, having sex in private, and?most unusual of all?having sex for fun instead of for procreation. Through comparative evolution, biologist and science author Diamond (Guns, Germs, and Steel: The Fate of Human Societies, LJ 2/15/97), poses credible and thought-provoking yet entertaining factors: the lengthy period of dependency of human infants, sex for pleasure as the tie that helps bind a mother and a father together, and menopause as an evolutionary advantage that, by ending the childbearing years, allows females to pass wisdom and knowledge on to society and succeeding generations.
