Abstract: Homosexual has always been a challenging problem in evolutionary biology. Natural
selection cannot explain the stable inheritance of homosexual, which is a phenotype with unclear
adaptive significance. In this paper, we briefly reviewed several theories to explain the
homosexual, ., fixed behavior pattern, Queer theory, abnormal relationship among parents and
kids, special experience during adolescence, disorder of androgen production, hypermutation,
sexual selection, kin selection, group selection, etc. Although we did not find a final solution to
the problem, the potential answer may still be the classic natural selection.
Key words: Homosexual, Gene, Natural selection

摘要:同性性行为一直是进化生物学的一个挑战,因为自然选择理论无法解释,这种无适应意义的先天性状为
什么会一代代遗传下来。本文回顾了历史上各个学科对人类同性恋行为的解释,分析了固定行为模式、酷儿理
论、幼儿-家长关系异常、青少年期特殊经历、胎儿期雄激素异常、超突变、性选择、亲缘选择、群体选择等
可能的理论解释。虽然现在仍旧没有一个理论能够满意地解答这个问题,但本文展望了解决这个问题的可能途
径,最终的答案仍在自然选择理论中。

是指同性之间情感或性的吸引,也可以指受
到这种吸引的个体。长久以来,同性恋这种
性状的成因一直困扰着科学家们。在大多数
