HOMOSEXUAL BEHAVIOUR IN ANIMALS: *

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.-------------El comportamiento homosexual está generalizado en todo el reino animal. Esta obra tiene por objeto examinar los aspectos evolutivos de las interacciones sexuales entre personas del mismo sexo. Con las contribuciones de lo que se conoce en este campo sobre las aves, delfines, ciervos, bisontes y gatos, así como monos y simios, incluidos los macacos, gorilas y bonobos, y un capítulo final sobre primates humanos, este libro cubre los conocimientos actuales en esta área de la sexología. Será de interés para los estudiantes de postgrado e investigadores en la biología evolutiva, la antropología biológica, la zoología, la psicología evolutiva y comportamiento animal.
