Of interest to all who work in the fields of anthropology, paleontology, anthropology and human biology, this book is the first to examine the role of women in the study of human evolution.

The author dispels some of the myths about the nature of females and female sexuality, and suggests new hypotheses aboutthe evolution of women.

As in the bestselling The Alphabet Versus the Goddess, Leonard Shlain’s provocative new book promises to change the way readers view themselves and where they came from. Sex, Time, and Power offers a tantalizing answer to an age-old question: Why did big-brained Homo sapiens suddenly emerge some 150,000 years ago? The key, according to Shlain, is female sexuality. Drawing on an awesome breadth of research, he shows how, long ago, the narrowness of the newly bipedal human female’s pelvis and the increasing size of infants’ heads precipitated a crisis for the species. Natural selection allowed for the adaptation of the human female to this environmental stress by reconfiguring her hormonal cycles, entraining them with the periodicity of the moon. The results, however, did much more than ensure our existence; they imbued women with the concept of time, and gave them control over sex—a power that males sought to reclaim. And the possibility of achieving immortality through heirs drove men to construct patriarchal cultures that went on to dominate so much of human history. From the nature of courtship to the evolution of language, Shlain’s brilliant and wide-ranging exploration stimulates new thinking about very old matters.

“A sparkling, thought-provoking account of sexual differences. Whether you’re a man or a woman, you’ll find his conclusions gripping.”—Jared Diamond There is a human genetic fluke that is surprisingly common, due to a change in a key pair of chromosomes. In the normal condition the two look the same, but in this disorder one is malformed and shrunken beyond recognition. The result is a shortened life span, higher mortality at all ages, an inability to reproduce, premature hair loss, and brain defects variously resulting in attention deficit, hyperactivity, conduct disorder, hypersexuality, and an enormous excess of both outward and self-directed aggression. It is called maleness. Melvin Konner traces the arc of evolution to explain the relationships between women and men. With patience and wit he explores the knotty question of whether men are necessary in the biological destiny of the human race. He draws on multiple, colorful examples from the natural world—such as the mating habits of the octopus, black widow, angler fish, and jacana—and argues that maleness in humans is hardly necessary to the survival of the species. In characteristically humorous and engaging prose, Konner sheds light on our biologically different identities, while noting the poignant exceptions that challenge the male/female divide. We meet hunter-gatherers such as those in Botswana, whose culture gave women a prominent place, invented the working mother, and respected women’s voices around the fire. Recent human history has upset this balance, as a dense world of war fostered extreme male dominance. But our species has been recovering over the past two centuries, and an unstoppable move toward equality is afoot. It will not be the end of men, but it will be the end of male supremacy and a better, wiser world for women and men alike.

Barash and Lipton discuss the theories scientists have advanced to explain evolutionary enigmas--from how women get their curves to why women menstruate--and present hypotheses of their own.

Geary (psychology and anthropology, U. of Missouri-Columbia) thinks culturally constructed gender roles alone cannot account for the differences in the social behavior of men and women. He turns to Darwin's theory of sexual selection as the best avenue for understanding. His main focus is how th etwo elements of competition between males and of females selecting mates has influenced human behavior over the centuries and across cultures.

Essays discuss chimpanzees as an evolutionary model, modern examples of hunter-gatherer tribes, women's and men's roles in prehistoric times, and primitive human adaptations
