Androphilia refers to sexual attraction and arousal to adult males, whereas gynephilia refers to sexual attraction and arousal to adult females. In Independent Samoa, androphilic males, most of whom are effeminate or transgendered, are referred to as fa’afafine, which means “in the manner of a woman.” Previous research has established that fa’afafine report significantly higher avuncular tendencies relative to gynephilic men. We hypothesized that Samoan fa’afafine might adopt feminine gender role orientations with respect to childcare activity. If so, then the (...) fa’afafine’s femininity might be a proximate mechanism for promoting their elevated avuncular tendencies. Our analyses indicated that fa’afafine had significantly higher willingness to assist in the childcare of nieces and nephews than childless women, mothers, or men, none of whom differed from each other on this measure. Thus, femininity does not appear to explain the fa’afafine’s pattern of avuncular tendencies, nor the women’s pattern of materteral (i.e., aunt-like) tendencies, relative to gynephilic men. We discuss how the fa’afafine “third” gender status might influence the expression of their elevated avuncular tendencies. (shrink)

Dispersal of individuals from their natal communities at sexual maturity is an important determinant of kin association. In this paper we compare postmarital residence patterns among Pumé foragers of Venezuela to investigate the prevalence of sex-biased vs. bilateral residence. This study complements cross-cultural overviews by examining postmarital kin association in relation to individual, longitudinal data on residence within a forager society. Based on cultural norms, the Pumé have been characterized as matrilocal. Analysis of Pumé marriages over a 25-year period finds (...) a predominant pattern of natalocal residence. We emphasize that natalocality, bilocality, and multilocality accomplish similar ends in maximizing bilateral kin affiliations in contrast to sex-biased residential patterns. Bilateral kin association may be especially important in foraging economies where subsistence activities change throughout the year and large kin networks permit greater potential flexibility in residential mobility.

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 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, thereby enhancing indirect fitness. Evidence supporting the KSH has been documented in Samoa. Samoan transgendered, androphilic males, (...) known locally as fa’afafine, are socially accepted by the majority of Samoans. In contrast, no supportive evidence has been garnered from other cultures that are characterized by less social tolerance toward male androphiles. Tests of the KSH in Canada might be more likely to yield findings consistent with Samoa because Canadian social and political attitudes toward male androphiles are markedly more tolerant and accepting. Here, we compared the willingness of Canadian androphilic men, gynephilic men, and androphilic women to invest in nieces and nephews as well as in non-kin children. Consistent with the KSH and findings from Samoa, androphilic men exhibited a significantly greater cognitive dissociation between altruistic tendencies directed toward kin versus non-kin children relative to gynephilic men and androphilic women. The present study, therefore, provides some tentative support for the KSH from a culture other than Samoa. Findings and future directions for research are considered within the context of the existing cross-cultural literature. (shrink)

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 posits that male androphilia may persevere over evolutionary time if the fitness costs of not reproducing directly are offset by increasing one’s inclusive fitness. Theoretically, this could be accomplished by allocating altruism toward close kin, thereby increasing the ability of those kin to reproduce. Evidence for this hypothesis has been garnered from research conducted in Samoa; (...) however, no support has been garnered from research conducted in other, more industrialized cultures. It has been suggested that geographic disconnect from kin might mitigate the potential for androphilic males to exhibit elevated kin-directed altruism in more industrialized cultures. We examined whether Canadian androphilic males expressed elevated willingness to engage in altruistic behavior towards nieces and nephews, compared to gynephilic males and androphilic females, when the activities in question could be executed from a distance. Contrary to our prediction, when comparing groups for willingness to engage in altruistic behavior towards nieces and nephews that could be performed from a distance, we did not find that Canadian androphilic males exhibited significantly higher avuncular tendencies. Other possible reasons for cross-cultural differences in avuncular tendencies by androphilic males are discussed. (shrink)
