The evolution of homoerotic behavior in humans

This paper presents a theoretical model for the evolution of same-sex sexua l behavior, or homoerotic behavior, in humans. Contrary to the traditional study of the topic, the emphasis is on homoerotic behavior itself; irrespec tive of sexual orientation. It is an inferential model drawn from cross-spe cies evidence, cross-cultural evidence, and current evolutionary theory. It is posited that humans evolved a disposition for homoerotic behavior becau se it increased same-sex affiliation among peripheralized hominids and indi rectly influenced rates of survival and reproductive success. The implicati ons for the conceptualization of same-sex sexual behavior and future resear ch are indicated.
