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 (i.e., Canada, USA, u K, Japan). 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 (uncle-like) tendencies. Other possible reasons for cross-cultural differences in avuncular tendencies by androphilic males are discussed. [ABSTRACT FROM AUTHOR]
