Humans are unique among primates for not only engaging in same-sex sexual acts, but also forming homosexual pair bonds. To shed light on the evolutionary origins of homosexuality, data on the occurrence and contexts of same-sex behavior from nonhuman primates may be of particular significance. Homosexual behavior involving females is poorly researched in most primate taxa, exceptions being Japanese macaques, rhesus macaques, Hanuman langurs and bonobos. We present data on homosexual behavior in…

Sociosexual behaviour in wild chimpanzees occurs in variable contexts and is frequent between same-sex partners

Although sociosexual behaviour may be less frequent in chimpanzees than in bonobos, and bonobos remain distinct in their genito-genital rubbing, the findings suggest that soci homosexual behaviour is a regular part of chimpanzee behaviour.

Anecdotal observation of a sexual encounter between two male naked mole-rats

Evidence of same-sex sexual behaviours in two male naked mole-rats for the first time is presented and it is speculated that dispersing individuals may be indiscriminatory in their mating strategy, copulating with conspecifics regardless of sex, to counter the risk of missed reproductive opportunities.

Male-Male Mounting Behaviour in Free-Ranging Golden Snub-Nosed Monkeys (Rhinopithecus roxellana)

An all-male band of golden snub-nosed monkeys (Rhinopithecus roxellana) was observed for 3 months in the Qinling Mountains of China, in order to collect data on the frequencies and contextual

Partner choice in genito-genital rubbing among female bonobos (Pan paniscus) is highly dependent on physical proximity.

Sociosexual interactions of non-human primates have multiple functions, and information on partner choice could help us to determine the major purpose of these behaviors. Female bonobos (Pan

The De-Scent of Sexuality: Did Loss of a Pheromone Signaling Protein Permit the Evolution of Same-Sex Sexual Behavior in Primates?

It is indicated that loss of TRPC2 function in developing mice leads to the loss or attenuation of sexually dimorphisms in the adult brain, which may help to understand the biological underpinnings of SSSB.

The De-Scent of Sexuality: Should We Smell a Rat?

Although some ideas in the proposed connection between the transient receptor potential cation channel 2 gene (TRPC2) and same-sex sexual behavior in primates are supported, greater caution is advocated when interpreting available data on SSSB.

A socio-ecological perspective on the gestural communication of great ape species, individuals, and social units

Over the last 30 years, most research on non-human primate gestural communication has been produced by psychologists, which has shaped the questions asked and the methods used. These researchers have

The evolving binary: perspectives on infra- and ultrahumanisation

We often pigeonhole our surroundings into dualistic categories, e.g., nature/culture. Perhaps evolutionary forces favoured dichotomous brains, or dualistic categories may be only social constructs.


Nowadays, the legal status of homosexual people varies widely from one country to another (ILGA 2019). In many contexts, the homosexual social movement has played a central role in fighting



Homosexual behavior in primates: A review of evidence and theory

  • P. Vasey
  • Psychology, Biology
    International Journal of Primatology
  • 2007
Exaptation is suggested as a theoretical framework for interpreting homosexual behavior and it is concluded that future consideration of sexual selection among primates should address homosexual components of this process.

The Evolution of Human Homosexual Behavior1

Three adaptationist hypotheses are reviewed here and compared with the anthropological literature and support is strongest, however, for the hypothesis that homosexual behavior comes from individual selection for reciprocal altruism.

Male‐male Interactions in Heterosexual and All‐male Wild Mountain Gorilla Groups

Variation in male dispersal and behavior patterns are components of intraspecific differences in social systems. A comparison of male behavior in different social settings can be useful for

Primate harassment of matings

Female relationships in bonobos(Pan paniscus)

Analysis of this bonding phenomenon sheds light on when, where, and how the authors should expect unrelated human females to bond with one another by demonstrating that bonding is not dependent on access to one’s relatives but rather on an environmental situation in which female aggregation is possible, coupled with an incentive for cooperation.

Sexual behavior in female western lowland gorillas (Gorilla gorilla gorilla): evidence for sexual competition

This study focused on sexual behaviors in a newly formed group of western lowland gorillas housed at Zoo Atlanta, finding further evidence for sexual competition among female gorillas and suggest that this may occur throughout their reproductive cycle rather than only during pregnancy.

Homosexual behaviour and female‐male mounting in mammals—a first survey

  • A. Dagg
  • Biology, Environmental Science
  • 1984
Information from the literature is given on the presence or absence of homosexual behaviour and female-male mounting in 125 species of mammals, both captive and wild. Such behaviour occurs in the

Homosexual mounting in free-ranging female Hanuman langurs (Presbytis entellus)

Although the ultimate function of homosexual female mounting is not fully understood, it is suspected to be connected with intrasexual competition: if “pseudocopulations” induce mountees to reduce the number of solicitations addressed to the male, the probability of insemination decreases and mounters thus reduce thenumber of future competitors.

Same-Sex Sexual Partner Preference in Hormonally and Neurologically Unmanipulated Animals

Understanding why same-sex sexual partner preference evolves in some species may involve abandoning a strictly functional perspective and, instead, approaching the issue from the perspective of each species' unique evolutionary history.

The results strongly support the ‘important relationships’ hypothesis for the function of reconciliation, which may avert or repair damage to long-term social relationships important to the animals' fitness.
