Sex, Time, and Power: How Women's Sexuality Shaped Human Evolution

Amazon.com
This book sets out to explore why and when people evolved so far away from other mammals in several key ways, all of which Dr. Shlain ties to the biological differences between men and women. As in his excellent prior work The Alphabet Versus the Goddess: The Conflict Between Word and Image (which holds that there are links between the ascendancy of patriarchy and written language and the descent of matriarchal societies and goddess-based religions), some of the concepts proposed in this book might seem a bit of a stretch. And they are—whether or not they turn out to be factual. Shlain contends, for instance, that women essentially invented the concept of time due to their experience of menses. Whatever conclusions the reader comes to, the author exposes the underlying gender biases in so many scientific assumptions; the result is one of those books that cannot help but alter one's perceptions. A consistently engaging writer, Shlain traces the course of his own evolving ideas with what might be called a didactic wit: bold statements are first writ large, then Dr. Shlain reveals how he came upon them, frequently with colorful anecdotes that show these are questions he's been wrestling with for many years. It's difficult to tell whether this fascinating thinker will be viewed as the next Darwin or as a crank, but there's no denying this is an audacious work in the realm of evolutionary biology. --Mike McGonigal

From Booklist
Shlain makes brilliant use of his medical expertise in his highly original and intellectually stimulating inquiry into human sexuality and its role in the shaping of civilization that he launched so boldly in The Alphabet versus the Goddess (1998). Here he takes an evolutionary approach to solving the conundrums of misogyny and patriarchy, guiding his curious, perhaps skeptical, certainly riveted readers through well-grounded and intriguing speculations about the purpose of such seemingly impractical, even dangerous traits as bipedalism, menstruation, the perils of childbirth, and the helplessness of infants. Shlain's reflections on human nutrition and women's greater need for iron lead to a fascinating theory about courtship and hunting, which, in turn, generates the hypothesis that the evolution of language was sparked by the delicacy of sexual negotiation. And menses, this daring thinker believes, may well be the source of our perception of time and our unique ability to conceive of and plan for the future. Lucid and compelling, Shlain asks startling and crucial questions about human nature and presents truly imaginative and mind-stretching answers. Donna Seaman

Book Description
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.

Few discussions of the evolution of homo sapiens look to the female as holding the key to developments that have resulted in our being a dominant force in nature. This analysis of gender differences and the manifestations and impacts of those differences is thought- provoking and could provide the basis for animated discussion. Stefan Rudinicki narrates in a straightforward, clear manner without talking down to his listener. He infuses energy into passages that might otherwise have a dry tone. Quotations from various writers that introduce sections of the book are read by a female voice, and a musical segue gives notice that a tape has ended. J.E.M. © AudioFile 2004, Portland, Maine
