“…SSSB has been a focus of study in some primate and ungulate species (e.g., in deer ( Cervus spp .) [ 2 ]; American bison ( Bison bison ) [ 3 ]; Japanese macaques ( Macaca fuscata ) [ 4 , 5 ]) yet has remained a low research priority in the field of evolutionary biology.…”

Same-sex sexual behaviour (SSSB) occurs in most animal clades, but published reports are largely concentrated in a few taxa. Thus, there remains a paucity of published reports for most mammalian species. We conducted a cross-sectional expert survey to better understand the underlying reasons for the lack of publications on this topic. Most respondents researched Primates (83.6%, N = 61), while the rest studied Carnivora (6.9%, N = 5), Rodentia (4.1%, N = 3), Artiodactyla (2.7%, N = 2), and Proboscidea (2.7%, N = 2). Most respondents (76.7%, N = 56) had observed SSSB in their study species, but only 48.2% (N = 27) collected data on SSSB, and few (18.5%, N = 5) had published papers on SSSB. Of the unique species identified as engaging in SSSB in the survey, 38.6% (N = 17) have no existing reports of SSSB to the knowledge of the authors. In both the survey questions and freeform responses, most respondents indicated that their lack of data collection or publication on SSSB was because the behaviours were rare, or because it was not a research priority of their lab. No respondents reported discomfort or sociopolitical concerns at their university or field site as a reason for why they did not collect data or publish on SSSB. Multiple logistic regressions were performed to assess whether taxa studied, education level, or identification within the LGBTQ+ community predicted observing, collecting data on, or publishing on SSSB, but none of these variables were significant predictors. These results provide preliminary evidence that SSSB occurs more frequently than what is available in the published record and suggest that this may be due to a publishing bias against anecdotal evidence.

“…Male androphilia (i.e., sexual attraction and arousal to adult males) is an evolutionary paradox (Bailey et al, 2016; Vasey et al, 2020). Despite reducing direct reproduction (e.g., Coome et al, 2020; Ganna et al, 2019; Schwartz et al, 2010; Vasey et al, 2014), this trait is influenced by genetic factors (e.g., Alanko et al, 2010; Ganna et al, 2019; Hamer, 2002; Långström et al, 2010; Sanders et al, 2015).…”

Male androphilia (i.e., sexual attraction to adult males) is considered an evolutionary paradox because it reduces direct reproduction but is influenced by genetic factors, reliably occurs across cultures, and has persisted over evolutionary time. The hypergyny hypothesis rests on the premise that the female relatives of androphilic males possess physical traits that signal fertility, such as elevated symmetry. If this premise were true, such traits could help attract reproductive partners with higher socioeconomic status, thereby furnishing resources to produce and sustain multiple offspring. This, in turn, would help females to offset their androphilic male siblings' lack of reproduction. The present study examined whether the sisters of male androphiles have elevated facial symmetry compared with women without androphilic male siblings. Sixty-six women with androphilic male siblings and 271 women without androphilic male siblings were recruited from Thailand and the Istmo region of Oaxaca, Mexico. Results demonstrated no significant differences in facial asymmetry between women with and without androphilic male siblings. In the absence of such a difference, this study, like previous ones, does not support the hypergyny hypothesis as a viable explanation for the evolutionary paradox of male androphilia. Public Significance StatementMales' sexual attraction to females and females' sexual attraction to males is perhaps the largest and most phylogenetically widespread of any psychological sex difference. The occurrence of exclusive male same-sex sexual attraction in most human cultures deviates from this common pattern. The present study is significant because it attempts to elucidate the evolutionary basis of male same-sex sexual attraction-a trait that has long perplexed evolutionists.
