Homosexual behavior is defined as genital contact, genital manipulation or both between same-sex individuals. Available data indicate that this behavior is phylogenetically widespread among the anthropoid primates, but totally absent among prosimians. The majority of the 33 species that demonstrate homosexual behavior do so rarefy, but for a substantial number (N =12) it appears to be a more common pattern under free-ranging conditions. I summarize data on homosexual behavior as it relates to…

Comparative Development of Heterosexual and Homosexual Behaviors in Free-Ranging Female Japanese Macaques

Significant differences in the development of heterosexual and homosexual behaviors in female Japanese macaques living at Arashiyama, Japan are explained in terms of risk of male aggression, males’ disinterest in adolescent females’ sexual solicitations, presence of motivated same-sex sexual partners, social facilitation, and sexual reward.

Human homosexuality: a paradigmatic arena for sexually antagonistic selection?

It is argued that multilocus, partially X-linked genetic factors undergoing sexually antagonistic selection that promote maternal female fecundity at the cost of occasional male offspring homosexuality are the best candidates capable of explaining the frequency, familial clustering, and pedigree asymmetries observed in HS male proband families.

In Defence of Animal Homosexuality

The claim that some animals exhibit homosexuality, that there are homosexual mental states in at least some nonhuman animals, and that these states may help to explain homosexual behaviours is supported.

There is insufficient evidence to conclude that homosexuality has endocrine bases, and it is suggested that, although such hypotheses are naive, their current popularity arises from their potential role in "controlling" homosexuality.

Homosexual incest avoidance among females in captive Japanese macaques

The present results point to the strong tendency of females to avoid incest and suggest that males are primarily responsible for the reported exceptions to incest avoidance, suggesting that female homosexuality expresses the reproductive strategy of females unconstrained by male influence.

Homosexual behavior in a laboratory group of stumptail monkeys (Macaca arctoides): Forms, contexts, and possible social functions

Observations of stumptail monkeys revealed frequent prolonged, intensive genital stimulation between individuals of the same sex, both males and females, adults and infants, suggesting that homosexual and heterosexual encounters function as training for adult sexual roles, and that homosexual behavior is a basic primate pattern not exclusive to man.
