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.

A breakthrough work in neuroscience—and an incisive corrective to a long history of damaging pseudoscience—that finally debunks the myth that there is a hardwired distinction between male and female brains We live in a gendered world, where we are ceaselessly bombarded by messages about sex and gender. On a daily basis, we face deeply ingrained beliefs that sex determines our skills and preferences, from toys and colors to career choice and salaries. But what does this constant gendering mean for our thoughts, decisions and behavior? And what does it mean for our brains? Drawing on her work as a professor of cognitive neuroimaging, Gina Rippon unpacks the stereotypes that surround us from our earliest moments and shows how these messages mold our ideas of ourselved and even shape our brains. By exploring new, cutting-edge neuroscience, Rippon urges us to move beyond a binary view of the brain and to see instead this complex organ as highly individualized, profoundly adaptable and full of unbounded potential. Rigorous, timely and liberating, Gender and Our Brains has huge implications for women and men, for parents and children, and for how we identify ourselves.

"In Gender Shock, Phyllis Burke explodes the many myths surrounding our rigid gender system of male and female by looking through three lenses of gender identity: behavior, appearance, and science. Analyzing the latest research in psychology, genetics, neurology, and sociology, Burke finds that gender (or behavior) is not the result of one's biological sex (the body itself) and that gender and sexuality are separate elements of the self. With common sense and compassion, Burke challenges the notion that men and women are from different planets by revealing how there are more variations within each sex than there are between the two."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Numerous cases illustrate the various ways e-mail and the Internet have an impact on how people relate to one another. Psychologist Civin (Adelphi U., and private practice) finds that some people and relationships are indeed profoundly affected in both negative and positive ways, and he describes various scenarios and syndromes that develop among the susceptible.

Human genomes are 99.9 percent identical—with one prominent exception. Instead of a matching pair of X chromosomes, men carry a single X, coupled with a tiny chromosome called the Y. Tracking the emergence of a new and distinctive way of thinking about sex represented by the unalterable, simple, and visually compelling binary of the X and Y chromosomes, Sex Itself examines the interaction between cultural gender norms and genetic theories of sex from the beginning of the twentieth century to the present, postgenomic age. Using methods from history, philosophy, and gender studies of science, Sarah S. Richardson uncovers how gender has helped to shape the research practices, questions asked, theories and models, and descriptive language used in sex chromosome research. From the earliest theories of chromosomal sex determination, to the mid-century hypothesis of the aggressive XYY supermale, to the debate about Y chromosome degeneration, to the recent claim that male and female genomes are more different than those of humans and chimpanzees, Richardson shows how cultural gender conceptions influence the genetic science of sex. Richardson shows how sexual science of the past continues to resonate, in ways both subtle and explicit, in contemporary research on the genetics of sex and gender. With the completion of the Human Genome Project, genes and chromosomes are moving to the center of the biology of sex. Sex Itself offers a compelling argument for the importance of ongoing critical dialogue on how cultural conceptions of gender operate within the science of sex.

With profound implications for our most foundational assumptions about gender, Gender Mosaic explains why there is no such thing as a male or female brain. For generations, we've been taught that women and men differ in profound and important ways. Women are more sensitive and emotional, whereas men are more aggressive and sexual, because this or that region in the brains of women is smaller or larger than in men, or because they have more or less of this or that hormone. This story seems to provide us with a neat biological explanation for much of what we encounter in day-to-day life. But is it true? According to neuroscientist Daphna Joel, it's not. And in Gender Mosaic, she sets forth a bold and compelling argument that debunks the notion of female and male brains. Drawing on the latest scientific evidence, including the groundbreaking results of her own studies, Dr. Joel explains that every human brain is a unique mixture -- or mosaic -- of "male" and "female" features, and that these mosaics don't map neatly into two categories. With urgent practical implications for the way we understand ourselves and the world around us, Gender Mosaic is a fascinating look at the science of gender, sex and the brain, and at how freeing ourselves from the gender binary can help us all reach our full human potential.

In 1987, more than a decade before the dawn of queer theory, Ifi Amadiume wrote Male Daughters, Female Husbands, to critical acclaim. This compelling and highly original book frees the subject position of 'husband' from its affiliation with men, and goes on to do the same for other masculine attributes, dislocating sex, gender and sexual orientation. Boldly arguing that the notion of gender, as constructed in Western feminist discourse, did not exist in Africa before the colonial imposition of a dichotomous understanding of sexual difference, Male Daughters, Female Husbands examines the structures in African society that enabled people to achieve power, showing that roles were not rigidly masculinized nor feminized. At a time when gender and queer theory are viewed by some as being stuck in an identity-politics rut, this outstanding study not only warns against the danger of projecting a very specific, Western notion of difference onto other cultures, but calls us to question the very concept of gender itself.
