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… 

Homosexual Behavior in Female Mountain Gorillas: Reflection of Dominance, Affiliation, Reconciliation or Arousal?

This work presents data on homosexual behavior in female mountain gorillas in the Virunga Volcanoes (Rwanda) and test four functional hypotheses, namely reconciliation, affiliation, dominance expression and sexual arousal.

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.

Nonhuman Primates Homosexual Behavior : A Critical Review of Literature

This paper provides a critical review of the literature on nonhuman primates sexual behavior. Reproduction and sexual behavior are of crucial importance in the biological and social sciences.

Testing the Affiliation Hypothesis of Homoerotic Motivation in Humans: The Effects of Progesterone and Priming

Findings constitute the first experimental support for the affiliation account of the evolution of homoerotic motivation in humans.

Skewed sex ratios and female homosexual activity in Japanese macaques: An experimental analysis

It is suggested that an abundance of certain types of preferred, same-sex sexual partners and/or a scarcity of opposite-sexSexual competitors best account for the increased levels of female homosexual behavior observed at this time.

Roberts, Glymour, and Koenen (2013), using instrumental variable models, argued that child abuse causes homosexual orientation, defined in part as any same-sex attractions. Their instruments were

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.



Is homosexuality hormonally determined?

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.

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

While the behavior of homosexuals in some aspects is subject to cultural variability, this analysis explores the equally important question of cultural invariability. Based on several years of field

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.

Hormones and Homosexuality

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.

Human sexual orientation. The biologic theories reappraised.

Critical review shows the evidence favoring a biologic theory to be lacking, and in an alternative model, temperamental and personality traits interact with the familial and social milieu as the individual's sexuality emerges.

Homosexuauty as a By-Product of Selection for Optimal Heterosexual Strategies

It is intended to show that at least some instances of homosexuality in humans might be a consequence of heterosexual frustration, dissatisfaction which derives from diese genderspecific differences, or both.


It is hypothesized that feral-born but cage-reared, sex-segregated chimpanzees are capable of normal mating behavior if they are given an opportunity to experiment and learn before a critical period occurring during late adolescence and early adulthood.

Sexual orientation, sociobiology, and evolution.

There is no reliable evidence that homosexual and heterosexual orientations are caused by genetic differences, and sociobiological explanations of homosexuality are found to be implausible and unsupported by evidence.
