尽管存在短期成本，但利他行为可以通过获得直接（自私）和/或间接（亲属选择）利益来增加个人的包容性健身。潜在配偶对他人关心或帮助行为的进化偏好被认为是一种额外的机制，通过这种机制，这些行为可以在人类中产生直接的健身益处。我们要求32名异性恋女性和35名异性恋男性在有和没有关于帮助行为的信息的情况下对异性成员的吸引力进行评级。帮助行为的报告与男性和女性作为潜在长期性伴侣的吸引力显着增加有关。利他主义也增加了男性作为短期伴侣的吸引力，但与考虑长期关系时相比，这种吸引力要小得多。利他主义并不影响女性作为短期伴侣的吸引力。我们的研究结果结合了进化理论的两个重要领域-社会进化和性选择-并扩展了帮助行为的手段列表，这些行为乍一看对行为者来说是昂贵的，实际上可以获得直接的健身益处。帮助行为可能是有吸引力的，因为它们标志着“好基因”和/或因为它们被视为可能提供非遗传益处（例如父母照顾）的信号。究竟为什么在非交配环境中的帮助行为可能对潜在的配偶有吸引力，以及它们是否是配偶质量的诚实信号，仍有待阐明。
Despite its short-term costs, behaviour that appears altruistic can increase an individual’s inclusive fitness by earning direct (selfish) and/or indirect (kin-selected) benefits. An evolved preference for other-regarding or helping behaviour in potential mates has been proposed as an additional mechanism by which these behaviours can yield direct fitness benefits in humans. We asked 32 heterosexual women and 35 heterosexual men to rate the attractiveness of members of the opposite sex in the presence and the absence of information about helping behaviours. Reports of helping behaviour were associated with a significant increase in the attractiveness of both men and women as potential long-term sexual partners. Altruism also increased the attractiveness of men as potential partners for short-term flings, but to a lesser extent than when the same men were being considered for long-term relationships. Altruism did not affect the attractiveness of women as partners for short-term flings. Our results unite two important areas of evolutionary theory – social evolution and sexual selection – and extend the list of means by which helping behaviours, which appear at first glance to be costly to the actor, can in fact earn direct fitness benefits. Helping behaviours may be attractive because they signal ‘good genes’ and/or because they are perceived as a signal of likely provision of non-genetic benefits (e.g. parental care). Exactly why helping behaviours in a non-mating context might be attractive to potential mates, and whether they are honest signals of mate quality, remains to be elucidated.
