A critical review of the debate over the still-hypothetical possibility of prenatal intervention by parents to select the sexual orientation of their children. Parents routinely turn to prenatal testing to screen for genetic or chromosomal disorders or to learn their child's sex. What if they could use similar prenatal interventions to learn (or change) their child's sexual orientation? Bioethicists have debated the moral implications of this still-hypothetical possibility for several decades. Some commentators fear that any scientific efforts to understand the origins of homosexuality could mean the end of gay and lesbian people, if parents shy away from having homosexual children. Others defend parents' rights to choose the traits of their children in general and see no reason to treat sexual orientation differently. In this book, Timothy Murphy traces the controversy over prenatal selection of sexual orientation, offering a critical review of the literature and presenting his own argument in favor of parents' reproductive liberty. Arguing against commentators who want to restrict the scientific study of sexual orientation or technologies that emerge from that study, Murphy proposes a defense of parents' right to choose. This, he argues, is the only view that helps protect children from hurtful family environments, that is consistent with the increasing powers of prenatal interventions, and that respects human futures as something other than accidents of the genetic lottery.
Why do men and women approach sex and romance differently? Anthropologist Heather Remoff employs a scientist's precision and a woman's wit to expose the bilogical rules behind the mating game. Women can use these insights to control their romantic destinies. The L.A. Times calls Sexual Choice "splendid...charming." People Magazine calls it "thoughtfully provocative." Women call it empowering.
Gender and Sexual Agency considers how heterosexual Latin American, Asian American, and Caucasian American youth negotiate sexual encounters. In particular, this book examines sexual agency, exploring the question of why some young people assertively pursue what they want in a sexual encounter, while others go along with sexual activity they do not want. By comparing both young men and young women, Heather Powers Albanesi offers a unique perspective on how an individual's emotional experience of gender informs his or her willingness to exercise sexual agency. Using interviews to support her theoretical argument, Albanesi offers profiles of eleven different types of sexual agency, ranging from having strong convictions about their sexual decisions to abdicating responsibility to their partner. As the expressers of sexual agency, the voices of these youth from primarily working-class backgrounds come through to take us into their sexual decisions as they understand and experience them within the context of their lives. Ultimately, regardless of the decision, the book shows that it is young people's experience of gender that both shapes and allows them to make sense of these sexual choices. Book jacket.
A major new look at the evolution of mating decisions in organisms from protozoans to humans The popular consensus on mate choice has long been that females select mates likely to pass good genes to offspring. In Mate Choice, Gil Rosenthal overturns much of this conventional wisdom. Providing the first synthesis of the topic in more than three decades, and drawing from a wide range of fields, including animal behavior, evolutionary biology, social psychology, neuroscience, and economics, Rosenthal argues that "good genes" play a relatively minor role in shaping mate choice decisions and demonstrates how mate choice is influenced by genetic factors, environmental effects, and social interactions. Looking at diverse organisms, from protozoans to humans, Rosenthal explores how factors beyond the hunt for good genes combine to produce an endless array of preferences among species and individuals. He explains how mating decisions originate from structural constraints on perception and from nonsexual functions, and how single organisms benefit or lose from their choices. Both the origin of species and their fusion through hybridization are strongly influenced by direct selection on preferences in sexual and nonsexual contexts. Rosenthal broadens the traditional scope of mate choice research to encompass not just animal behavior and behavioral ecology but also neurobiology, the social sciences, and other areas. Focusing on mate choice mechanisms, rather than the traits they target, Mate Choice offers a groundbreaking perspective on the proximate and ultimate forces determining the evolutionary fate of species and populations.
The true role of biology in determining sexual orientation is an oft-debated issue in both the popular media and scientific communities, and evaluating the literature on the topic can be daunting. Nature’s Choice: What Science Reveals About the Biological Origins of Sexual Orientation offers both a comprehensive review of the scientific literature and a fresh perspective on this complex and politically charged subject. Respected researcher, speaker, and author Dr. Cheryl Weill offers readers of all backgrounds an enlightening analysis of findings from over twenty years of research on the factor of biology in the determination of sexual orientation. Nature’s Choice: What Science Reveals About the Biological Origins of Sexual Orientation brilliantly distills complicated studies and research findings dealing with brain anatomy, genetics, sex-typical behavior in children, auditory, startle reflex, and many other areas. Spanning a wide range of important topics including human sexual development and the effects of hormones, Ellis and Ames’ Gestational Neurohormonal Theory, the ins, outs, and implications of how scientific research is funded, and model of the role of testosterone in determining human sexuality, Nature’s Choice: What Science Reveals About the Biological Origins of Sexual Orientation is an exciting book to educate and inspire readers from scientific and non-scientific backgrounds equally.
This root-and-branch re-evaluation of Darwin’s concept of sexual selection tackles the subject from historical, epistemological and theoretical perspectives. Contributions from a wealth of disciplines have been marshaled for this volume, with key figures in behavioural ecology, philosophy, and the history of science adding to its wide-ranging relevance. Updating the reader on the debate currently live in behavioural ecology itself on the centrality of sexual selection, and with coverage of developments in the field of animal aesthetics, the book details the current state of play, while other chapters trace the history of sexual selection from Darwin to today and inquire into the neurobiological bases for partner choices and the comparisons between the hedonic brain in human and non-human animals. Welcome space is given to the social aspects of sexual selection, particularly where Darwin drew distinctions between eager males and coy females and rationalized this as evolutionary strategy. Also explored are the current definition of sexual selection (as opposed to natural selection) and its importance in today’s biological research, and the impending critique of the theory from the nascent field of animal aesthetics. As a comprehensive assessment of the current health, or otherwise, of Darwin’s theory, 140 years after the publication of his Descent of Man, the book offers a uniquely rounded view that asks whether ‘sexual selection’ is in itself a progressive or reactionary notion, even as it explores its theoretical relevance in the technical biological study of the twenty-first century.
Unravelling the complexities of relationships and sexuality, this straight-talking guide will help you to navigate the associated social, emotional and physical issues. Expert advice and real life examples give you the knowledge to reflect on your own sexuality, provide you with information on different types of relationship, and gives you the confidence to decide which type of relationship is right for you. Together with important information on sexual health, this book will help you to understand how to find and maintain a relationship of your choosing in a safe and enjoyable way. Exploring the often unspoken rules of sex and relationships, this book also covers often unaddressed topics, such as: · what sexual attraction looks and feels like · how to identify your own sexual identity and preferences (and how they may change) · what your rights are, and how to stay safe · having children, or choosing not to, the impact of this on relationships · how to recognise power imbalances within relationships, and what to do
