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 is a 2006 text which 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.
Industry Reviews
Review of the hardback: 'For anyone interested in animal behaviour, this book is a valuable reference which brings together a collection of current research into homosexual behaviour in animals in one volume.' Biologist
Review of the hardback: 'Sommer and Vasey have sharply steered the Darwinian study of homosexual behaviour out of its infancy and towards all the defining features of a mature science ... the book deserves to be widely read by researchers interested in ultimate functions of human and animal behaviour alike.' Journal of Evolutionary Psychology
'... I highly recommend this book to scholars, but also to anyone wishing to broaden their understanding of this perfectly natural and fascinating facet of animal behaviour, including our own species.' Dr F. Blake Morton , Primate Eye
'... the book ... gives readers a useful foundation for understanding key findings and research trajectories that are applicable to any species. ...
