Valuing Behavioral By‐Products: Evolutionary Significance of Neutrally Drifting and Exaptive Cultures in Primates
After challenging the view that cultural processes mainly produce behavioral adaptations, we urge researchers to adopt a pluralistic view on Darwinian evolution by emphasizing the diversity and importance of evolutionary by‐products and highlighting the heuristic merit of concepts such as behavioral spandrels and exaptations, particularly in the domain of cultural evolution in primates. We then use the concept of the “structure‐function interface…

Association of Recalled Childhood Sex-Typed Behavior with Sexual Orientation and Gender Identity in Iranian Adult Males and Females
Same-sex sexual attraction in both males and females has been associated with childhood sex-atypical behavior. Gynephilic females recall behaving in a manner that is less female-typical and more male-typical compared to cisgender androphilic females, whereas androphilic males recall behaving in a manner that is less male-typical and more female-typical compared to cisgender gynephilic males. In addition, male and female ambiphilic individuals exh…

When males have females on their backs: Male's tolerance, solicitation, and use of female–male mounting in Japanese macaques
Previous research on Japanese macaques has shown that female‐to‐male mounting (FMM) is performed by some females as an exaggerated form of sexual solicitation that may occur in the context of high female competition for male mates. This supernormal courtship behavior functions to prompt subsequent male‐to‐female mounting. In this report, we focused on the male consort partners' responses to FMM. We studied a free‐ranging population of Japanese ma…
Men’s Sexual Interest in Feminine Trans Individuals across Cultures
Feminine trans individuals (i.e., individuals who were assigned male at birth but who have a feminine gender presentation and identity) are present in many cultures. In some cultures, these individuals identify as (trans) women. Many of these individuals undergo medical treatments to feminize their bodies (e.g., breast augmentation), but most do not undergo vaginoplasties and therefore have penises. In many non-Western cultures, feminine trans in…
Confounds, Causality, and Sexual Orientation: The Implications of a Population-Level Study of Sibling Characteristics and Same-Sex Attraction
Representative samples, and especially population samples, are coveted sources of high-quality data in psychological science. In their recent article, Ablaza et al. (2021) used a population sample of marriages and registered partnerships in the Netherlands to examine the relationships between sibling characteristics and sexual orientation. We discuss the implications of this work for understanding the fraternal and sororal birth order effects on …

Facial Attractiveness of the Sisters of Istmo Zapotec Men and Muxes: Implications for the Evolution of Male Androphilia
Research shows that the female relatives of androphilic (i.e., sexually attracted to adult males) males have more children than the female relatives of gynephilic (i.e., sexually attracted to adult females) males. The mechanisms by which this occurs are unclear. The hypergyny hypothesis suggests that the female relatives of androphilic males have elevated attractiveness which allows them to obtain male partners with higher socioeconomic status, w…

Patterns and Universals of Adult Romantic Attachment Across 62 Cultural Regions: Are Models of Self and of Other Pancultural Constructs
As part of the International Sexuality Description Project, a total of 17,804 participants from 62 cultural regions completedthe RelationshipQuestionnaire(RQ), a self-reportmeasure of adult romanticattachment. Correlational analyses within each culture suggested that the Model of Self and the Model of Other scales of the RQ were psychometrically valid within most cultures. Contrary to expectations, the Model of Self and Model of Other dimensions …

Familial Patterning and Prevalence of Male Androphilia in Samoa
Previous research established that male androphilia (i.e., sexual arousal and attraction to adult males) clusters in families. Some studies find that male androphilia clusters in both the paternal and maternal lines, while others find that it clusters only in the latter. Most of the research investigating the familial nature of male androphilia has taken place in Western cultural contexts that are problematic for such research because they are ch…

Reconsidering male bisexuality: Sexual activity role and sexual attraction in Samoan men who engage in sexual interactions with Fa’afafine
In many non Western cultures, same-sex attracted males are markedly feminine in terms of their gender role presentation and are recognized as members of a gender. These third gender males engage in sexual activity with masculine males who are recognized as men. The sexual orientation of these masculine men remains an open question. Using a Samoan sample (N = 100), the current study employed measures of self-report and viewing time (a measure that…
Male Sexual Orientation and Avuncularity in Canada: Implications for the Kin Selection Hypothesis
Androphilia refers to sexual attraction and arousal to adult males, whereas gynephilia refers to sexual attraction and arousal to adult females. The Kin Selection Hypothesis (KSH) posits that genes for male androphilia can persist if androphilic males offset the fitness costs of not reproducing directly by enhancing indirect fitness. In theory, by directing altruistic behavior toward kin, androphilic males can increase the reproduction of kin, th…

Intimate sexual relations in prehistory: Lessons from the Japanese macaques
The goal of this paper is to discuss the implications of research on female homosexual behaviour in Japanese macaques (Macaca fuscata) for reconstructing intimate sexual relations in prehistory. I argue that an adaptationist approach to sex formulated within the context of sexual selection theory has dictated, by and large, how prehistorians envision these relationships. I demonstrate how studies of female homosexual behaviour in Japanese macaque…

Is Gender Identity Disorder in Children a Mental Disorder
Same-Sex Sexual Partner Preference in Hormonally and Neurologically Unmanipulated Animals
Proximate and ultimate biological theories for understanding sexual behavior predict that sexual dimorphism in sexual partner preference should be ubiquitous in the animal kingdom. A review of the literature found evidence for same-sex sexual partner preference in a small number of species (female pukekos, cows, domestic rams, female Uganda kobs, female Japanese macaques). Thus, theoretical predictions concerning the development and evolution of …

Sex differences in sexual partner acquisition, retention, and harassment during female homosexual consortships in Japanese macaques
Female Japanese macaques ( Macaca fuscata ) in certain populations are unusual in that they exhibit male‐typical patterns of mounting behavior and sexual‐partner preference. The goal of this study was to determine whether female Japanese macaques, from one such population, employ male‐typical behavioral tactics to disrupt existing homosexual consortships, as well as to acquire and retain same‐sex sexual partners. “Harassment” of homosexual consor…

Separation Anxiety in Feminine Boys: Pathological or Prosocial
Previous research has found that boys who exhibit Gender Identity Disorder in Children (GIDC) also commonly exhibit elevated traits of childhood separation anxiety. Here, we review recent cross-cultural, nonclinical research that suggests elevated childhood separation anxiety is simply a component of the more general pattern of femininity exhibited by pre-androphilic males (i.e., biological males who are sexually attracted to adult males in adult…
