Showing results for "EVOLUTION" in Gender Issues

In Survival of the Prettiest, Nancy Etcoff, a faculty member at Harvard Medical School and a practicing psychologist at Massachusetts General Hospital, argues that beauty is neither a cultural construction, an invention of the fashion industry, nor a backlash against feminism - it's in our biology.

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 reconfiguration of hormonal cycles, entraining women with the periodicity of the moon - and imbuing women with the concept of time.

Maternal instinct - the all-consuming, utterly selfless love that mothers lavish on their children - has long been assumed to be an innate, indeed defining element of a woman's nature. But is it? In this provocative, groundbreaking audiobook, renowned anthropologist (and mother) Sarah Blaffer Hrdy shares a radical new vision of motherhood and its crucial role in human evolution. Hrdy strips away stereotypes and gender-biased myths to demonstrate that traditional views of maternal behavior are essentially wishful thinking codified as objective observation.

In this innovative celebration of diversity and affirmation of individuality in animals and humans, Joan Roughgarden challenges accepted wisdom about gender identity and sexual orientation. A distinguished evolutionary biologist, Roughgarden takes on the medical establishment, the Bible, social science--and even Darwin himself. She leads the reader through a fascinating discussion of diversity in gender and sexuality among fish, reptiles, amphibians, birds, and mammals, including primates. Evolution's Rainbow explains how this diversity develops from the action of genes and hormones and how people come to differ from each other in all aspects of body and behavior. Roughgarden reconstructs primary science in light of feminist, gay, and transgender criticism and redefines our understanding of sex, gender, and sexuality. A new preface shows how this witty, playful, and daring book has revolutionized our understanding of sexuality.

While we joke that men are from Mars and women are from Venus, our gender differences can't compare to those of other animals. For instance: the male garden spider spontaneously dies after mating with a female more than fifty times his size. Female cichlids must guard their eggs and larvae--even from the hungry appetites of their own partners. And male blanket octopuses employ a copulatory arm longer than their own bodies to mate with females that outweigh them by four orders of magnitude. Why do these gender gulfs exist?

Are the ways we look at menopause all wrong? Historian Susan Mattern says yes, and The Slow Moon Climbs reveals just how wrong we have been. Taking listeners from the rainforests of Paraguay to the streets of Tokyo, Mattern draws on historical, scientific, and cultural research to reveal how our perceptions of menopause developed from prehistory to today. For most of human history, people had no word for menopause and did not view it as a medical condition. Rather, in traditional foraging and agrarian societies, it was a transition to another important life stage.

In The Genial Gene, Joan Roughgarden forcefully rejects ideas that have come to dominate the study of animal evolution. Building on her brilliant and innovative book Evolution's Rainbow, in which she challenged accepted wisdom about gender identity and sexual orientation, Roughgarden upends the notion of the selfish gene and the theory of sexual selection and develops a compelling and controversial alternative theory called social selection.

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.
