Behavioural observations from both the field and captivity indicate that same-sex sexual interactions are widespread throughout the animal kingdom, and occur quite frequently in certain non-human species. Proximate studies of these phenomena have yielded important insights into genetic, hormonal and neural correlates. In contrast, there has been a relative paucity of research on the evolutionary aspects. Homosexual Behaviour in Animals seeks to readdress this imbalance by exploring animal same-sex sexual behaviour from an evolutionary perspective. Contributions focus on animals that routinely engage in homosexual behaviour and include birds, dolphin, deer, bison and cats, as well as monkey and apes, such as macaques, gorillas and bonobos. A final chapter looks at human primates. This book will appeal to graduate students and researchers in evolutionary biology, biological anthropology, zoology, evolutionary psychology, animal behaviour and anyone interested in the current state of knowledge in this area of behavioural studies.

Homosexuality is an evolutionary paradox in search for a resolution, not a medical condition in search for a cure. Homosexual behavior is common among social animals, and mainly expressed within the context of a bisexual sexual orientation. Exclusive homosexuality is less common, but not unique to humans. Poiani and Dixson invite the reader to embark on a journey through the evolutionary, biological, psychological and sociological aspects of homosexuality, seeking an understanding of both the proximate and evolutionary causes of homosexual behavior and orientation in humans, other mammals and birds. The authors also provide a synthesis of what we know about homosexuality into a biosocial model that links recent advances in reproductive skew theory and various selection mechanisms to produce a comprehensive framework that will be useful for anyone teaching or planning future research in this field.

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. Witty, playful, and daring, this book will revolutionize our understanding of sexuality. Roughgarden argues that principal elements of Darwinian sexual selection theory are false and suggests a new theory that emphasizes social inclusion and control of access to resources and mating opportunity. She disputes a range of scientific and medical concepts, including Wilson's genetic determinism of behavior, evolutionary psychology, the existence of a gay gene, the role of parenting in determining gender identity, and Dawkins's "selfish gene" as the driver of natural selection. She dares social science to respect the agency and rationality of diverse people; shows that many cultures across the world and throughout history accommodate people we label today as lesbian, gay, and transgendered; and calls on the Christian religion to acknowledge the Bible's many passages endorsing diversity in gender and sexuality. Evolution's Rainbow concludes with bold recommendations for improving education in biology, psychology, and medicine; for democratizing genetic engineering and medical practice; and for building a public monument to affirm diversity as one of our nation's defining principles.

The Biology Of Homosexuality written by Jacques Balthazart and has been published by Oxford University Press this book supported file pdf, txt, epub, kindle and other format this book has been release on 2012 with Medical categories.
In this fascinating book, Jacques Balthazart presents a simple description of the biological mechanisms that are involved in the determination of sexual orientation in animals and also presumably in humans. Using scientific studies published over the last few decades, he argues that sexual orientation, both homosexual and heterosexual, is under the control of embryonic endocrine and genetic phenomena in which there is little room for individual choice. The author begins with animal studies of the hormonal and neural mechanisms that control the so-called instinctive behaviors and analyzes how this animal work may potentially apply to humans. The book does not focus exclusively on homosexuality, however. Instead, the book acts as a broader guide to the biological basis of sexual orientation, and also discusses important gender differences that may influence sexual orientation. While firmly grounded in the scientific literature, this text is developed for a broader audience and will be of interest to psychologists, researchers, students, and anyone interested in the biological factors that determine our sexuality.

This remarkable primate with the curious name is challenging established views on human evolution. The bonobo, least known of the great apes, is a female-centered, egalitarian species that has been dubbed the "make-love-not-war" primate by specialists. In bonobo society, females form alliances to intimidate males, sexual behavior (in virtually every partner combination) replaces aggression and serves many social functions, and unrelated groups mingle instead of fighting. The species's most striking achievement is not tool use or warfare but sensitivity to others. In the first book to combine and compare data from captivity and the field, Frans de Waal, a world-renowned primatologist, and Frans Lanting, an internationally acclaimed wildlife photographer, present the most up-to-date perspective available on the bonobo. Focusing on social organization, de Waal compares the bonobo with its better-known relative, the chimpanzee. The bonobo's relatively nonviolent behavior and the tendency for females to dominate males confront the evolutionary models derived from observing the chimpanzee's male power politics, cooperative hunting, and intergroup warfare. Further, the bonobo's frequent, imaginative sexual contacts, along with its low reproduction rate, belie any notion that the sole natural purpose of sex is procreation. Humans share over 98 percent of their genetic material with the bonobo and the chimpanzee. Is it possible that the peaceable bonobo has retained traits of our common ancestor that we find hard to recognize in ourselves? Eight superb full-color photo essays offer a rare view of the bonobo in its native habitat in the rain forests of Zaire as well as in zoos and research facilities. Additional photographs and highlighted interviews with leading bonobo experts complement the text. This book points the way to viable alternatives to male-based models of human evolution and will add considerably to debates on the origin of our species. Anyone interested in primates, gender issues, evolutionary psychology, and exceptional wildlife photography will find a fascinating companion in Bonobo: The Forgotten Ape. This remarkable primate with the curious name is challenging established views on human evolution. The bonobo, least known of the great apes, is a female-centered, egalitarian species that has been dubbed the "make-love-not-war" primate by specialists. In

For all the discussion in the media about creationism and 'Intelligent Design', virtually nothing has been said about the evidence in question - the evidence for evolution by natural selection. Yet, as this succinct and important book shows, that evidence is vast, varied, and magnificent, and drawn from many disparate fields of science. The very latest research is uncovering a stream of evidence revealing evolution in action - from the actual observation of a species splitting into two, to new fossil discoveries, to the deciphering of the evidence stored in our genome. Why Evolution is True weaves together the many threads of modern work in genetics, palaeontology, geology, molecular biology, anatomy, and development to demonstrate the 'indelible stamp' of the processes first proposed by Darwin. It is a crisp, lucid, and accessible statement that will leave no one with an open mind in any doubt about the truth of evolution.

Sinners and Citizens explores how sexual habits changed in Sweden during its development from an agrarian society into a modern welfare state. Jens Rydström examines the history of homosexuality and bestiality in that country to consider why these sexual practices have been so closely linked in virtually all Western societies. He limns sharply the distinctive experience of rural life, showing that to regularly witness farm animals stirred passions and sparked ideas, especially among young farmhands. Based on medical journals, psychiatric reports, and court records from the period, as well as testimonies from men in diaries, letters, and interviews, Sinners and Citizens reveals that bestiality was once a dreaded crime in Sweden. But in time, mention of the practice disappeared completely from legal and medical debates. This, Rydström contends, is because models of penetrative sodomy shifted from bestiality to homosexuality as Sweden transformed from a rural society into a more urban one. As the nation's economy and culture became less identified with the countryside, so too did its idea of deviant sexual behavior.
