REPRODUCTIVE STRATEGIES AND GENDER CONSTRUCTION - AN EVOLUTIONARY VIEW OF HOMOSEXUALITIES

In this chapter the author addresses the following question: Can the historical occurrence of various forms of homosexuality and bisexuality be explained as part of the management of reproduction in response to environmental conditions? She believes that explanations for the occurrence and forms of homosexuality appealing to genetics are biologically indefensible and historically inadequate. However, Darwinian behavioral theory, and specifically that subset termed life history theory, provides an explanatory framework. An individual's life course consists of behaviors coerced by parents and chosen by the individual in response to environmental conditions, forming a coherent reproductive strategy. In the process, alternate male and female genders, such as cadet sons, spinsters, and religious celibates are explained and the normative male bisexuality of Classical Athens and modem Mediterranean/Latin societies is elucidated. The rise of modern homosexuality in industrial nations results from the demographic transition to low mortality and low fertility, relaxing the reproductive management of children by parents and permitting a greater role for temperament in individual sexual and gender choices.
