Homosexual Behaviour in Animals An Evolutionary Perspective [Hardcover]

This book explores evolutionary aspects of same-sex sexual behaviour in animals.Originally published in 2006, Homosexual Behaviour in Animals will appeal to anyone interested in this area of sexology. Primarily aimed at graduate students and researchers in evolutionary biology, biological anthropology, zoology, evolutionary psychology and animal behaviour, it contains contributions covering a variety of mammals, primates and birds.Originally published in 2006, Homosexual Behaviour in Animals will appeal to anyone interested in this area of sexology. Primarily aimed at graduate students and researchers in evolutionary biology, biological anthropology, zoology, evolutionary psychology and animal behaviour, it contains contributions covering a variety of mammals, primates and birds.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 redress 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 monkeys 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.Part I.
