同性恋行为的存在一直是一个广泛被讨论的问题,此文提出两个行为学假设来给同性恋行为解释框架添砖加瓦。父辈投资假设认为,男性增加其女性性征以获得女性长期择偶的青睐,从而潜行交配假设认为,男性个体呈现其被男性吸引的状态,降低其本身性威胁程度,以获得与女性接近的机会来赢得繁衍的可能。两种假设互相补充,在不同的环境背景中被激活,发挥出对成功繁衍的最好促进作用。
The existence of homosexuality has been a widely discussed issue, and the article proposes two behavioral assumptions that complement the framework of homosexual behavior interpretation. Parents’ investment hypothesis argues that men increase their female sexual favors to gain the favor of women for long-term mate selection, so that the sneaking copulation hypothesis holds that male individuals exhibit their state of being attracted by men and reduce their own sexual threats to gain access to women Winning the possibility of reproduction. The two assumptions complement each other and are activated in different contexts to give the best boost to successful reproduction.
