Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: A Publishers Weekly Best Book One of the New York Public Library's "25 Books to Remember" for 1999 Lavishly illustrated and meticulously researched, filled with fascinating facts and astonishing descriptions of animal behavior, Bruce Bagemihl's Biological Exuberance is a landmark book that will change forever how we look at nature. Homosexuality in its myriad forms has been scientifically documented in more than 450 species of mammals, birds, reptiles, insects, and other animals worldwide. Biological Exuberance is the first comprehensive account of the subject, bringing together accurate, accessible, and nonsensationalized information. Drawing upon a rich body of zoological research spanning more than two centuries, Bagemihl shows that animals engage in all types of nonreproductive sexual behavior. Sexual and gender expression in the animal world displays exuberant variety, including same-sex courtship, pair-bonding, sex, and co-parenting—even instances of lifelong homosexual bonding in species that do not have lifelong heterosexual bonding. Part 1, "A Polysexual, Polygendered World," begins with a survey of homosexuality, transgender, and nonreproductive heterosexuality in animals and then delves into the broader implications of these findings, including a valuable perspective on human diversity. Bagemihl also examines the hidden assumptions behind the way biologists look at natural systems and suggests a fresh perspective based on the synthesis of contemporary scientific insights with traditional knowledge from indigenous cultures. Part 2, "A Wondrous Bestiary," profiles more than 190 species in which scientific observers have noted homosexual or transgender behavior. Each profile is a verbal and visual "snapshot" of one or more closely related bird or mammal species, containing all the documentation required to support the author's often controversial conclusions.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: To observe a dog's guilty look. to witness a gorilla's self-sacrifice for a wounded mate, to watch an elephant herd's communal effort on behalf of a stranded calf--to catch animals in certain acts is to wonder what moves them. Might there he a code of ethics in the animal kingdom? Must an animal be human to he humane? In this provocative book, a renowned scientist takes on those who have declared ethics uniquely human Making a compelling case for a morality grounded in biology, he shows how ethical behavior is as much a matter of evolution as any other trait, in humans and animals alike. World famous for his brilliant descriptions of Machiavellian power plays among chimpanzees-the nastier side of animal life--Frans de Waal here contends that animals have a nice side as well. Making his case through vivid anecdotes drawn from his work with apes and monkeys and holstered by the intriguing, voluminous data from his and others' ongoing research, de Waal shows us that many of the building blocks of morality are natural: they can he observed in other animals. Through his eyes, we see how not just primates but all kinds of animals, from marine mammals to dogs, respond to social rules, help each other, share food, resolve conflict to mutual satisfaction, even develop a crude sense of justice and fairness. Natural selection may be harsh, but it has produced highly successful species that survive through cooperation and mutual assistance. De Waal identifies this paradox as the key to an evolutionary account of morality, and demonstrates that human morality could never have developed without the foundation of fellow feeling our species shares with other animals. As his work makes clear, a morality grounded in biology leads to an entirely different conception of what it means to he human--and humane.

Available in PDF, EPUB and Kindle. Book excerpt: What causes a child to grow up gay or straight? In this book, neuroscientist Simon LeVay summarizes a wealth of scientific evidence that points to one inescapable conclusion: Sexual orientation results primarily from an interaction between genes, sex hormones, and the cells of the developing body and brain. LeVay helped create this field in 1991 with a much-publicized study in Science, where he reported on a difference in the brain structure between gay and straight men. Since then, an entire scientific discipline has sprung up around the quest for a biological explanation of sexual orientation. In this book, LeVay provides a clear explanation of where the science stands today, taking the reader on a whirlwind tour of laboratories that specialize in genetics, endocrinology, neuroscience, cognitive psychology, evolutionary psychology, and family demographics. He describes, for instance, how researchers have manipulated the sex hormone levels of animals during development, causing them to mate preferentially with animals of their own gender. LeVay also reports on the prevalence of homosexual behavior among wild animals, ranging from Graylag geese to the Bonobo chimpanzee. Although many details remain unresolved, the general conclusion is quite clear: A person's sexual orientation arises in large part from biological processes that are already underway before birth. LeVay also makes it clear that these lines of research have a lot of potential because--far from seeking to discover "what went wrong" in the lives of gay people, attempting to develop "cures" for homosexuality, or returning to traditional explanations that center on parent-child relationships, various forms of "training," or early sexual experiences--our modern scientists are increasingly seeing sexual variety as something to be valued, celebrated, and welcomed into society.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: NPR's "All Things Considered," calls Queer Ducks "teenager-friendly. It's a young adult book filled with comics and humor and accessible science, and it's filled with research on the diversity of sexual behavior in the animal world." This groundbreaking illustrated YA nonfiction title from two-time National Book Award finalist and New York Times bestselling author Eliot Schrefer is a well-researched and teen-friendly exploration of the gamut of queer behaviors observed in animals. A quiet revolution has been underway in recent years, with study after study revealing substantial same-sex sexual behavior in animals. Join celebrated author Eliot Schrefer on an exploration of queer behavior in the animal world—from albatrosses to bonobos to clownfish to doodlebugs. In sharp and witty prose—aided by humorous comics from artist Jules Zuckerberg—Schrefer uses science, history, anthropology, and sociology to illustrate the diversity of sexual behavior in the animal world. Interviews with researchers in the field offer additional insights for readers and aspiring scientists. Queer behavior in animals is as diverse and complex—and as natural—as it is in our own species. It doesn’t set us apart from animals—it bonds us even closer to our animal selves.

Available in PDF, EPUB and Kindle. Book excerpt: This groundbreaking work draws on a vast range of research into human sexuality to demonstrate that homosexuality is not a phenomenon limited to a small minority of society, but is an aspect of a complex sexual harmony that the human race inherited from its animal ancestors. Through a survey of the patterns of sexual expression found among animals and among societies around the world, and an examination of the functional role homosexual behavior has played among animal species and human societies alike, the author arrives at some provocative conclusions: that a homosexual or bisexual phase is a normal part of sexual development, that same-sex relations play an important balancing role in regulating human reproduction, that many societies have institutionalized homosexual traditions in the past, and that the harsh condemnation of homosexuality in Western society is a relatively recent phenomenon, unique among world societies throughout history. This well researched and meticulously documented book is the first that integrates into a coherent picture the startling revelations about human sexuality coming from the recent work of sexual researchers, psychologists, anthropologists and historians. The view that emerges, of an ambisexual human species whose complex sexual harmony is being thwarted by the imposition of an artificial understanding of nature, represents a new way of thinking about sex.
