Showing results for "Biological Science" in Gender Issues

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.

Ambika Kamath and Melina Packer reveal how scientists studying animal behavior have long projected human norms and values onto animals while seeking to understand them. When scientific studies conclude that these norms and values are natural in animals, it makes it easier to think of them as natural in humans too. And because scientists, historically and to this day, largely belong to elite, powerful segments of society, the norms and values embedded into animal behavior science match those of the already powerful.

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.

"Este libro indaga sobre diferencias y similitudes entre los seres humanos con un objetivo fundamental: enseñar. La divulgación del conocimiento en medicina es una tarea clave en la prevención de las enfermedades y en la mejora de la calidad de vida." (Del prólogo de Facundo Manes)

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.

The term "gender" was first distinguished from "sex" in the 1950s when psychologists began to discuss the idea of "gender roles", behaviors and responsibilities given to people by a society rather than flowing from their biology. Since then, leaders across disciplines have sought to better understand the roles of biology, psychology, and culture on gender. New language has emerged alongside rich scientific inquiry and research. Increased visibility of transgender and nonbinary communities has brought awareness to a range of gender diverse experiences....
