同性恋的进化心理学理论模型述评

Evolutionary Psychology Theoretical Models of Homosexuality

关于同性恋的成因,进化心理学家有不同的解释,主要包括杂合优势、女性多产、超突变、亲族选择、群体选择、同盟形成以及父母操纵七种理论假说。在系统地介绍这些理论假说的基础上比较了各理论之间的优缺点,并将其与其他流派的观点做对比,以期发现更具说服力的模型。未来的研究应该注意同性恋的性别差异、影响性取向基因的确切位置等。

There are many theoretical models, postulated by evolutionary psychologists, for explaining the evolution mechanism of homosexuality; including heterozygote superiority, fertile females, hypervariability, kin selection, group-selection, alliance formation and parental manipulation. In the present review, these theoretical models were systematically introduced, and comparised with each other. These evolutionary psychological theories were also comparised with that of other schools for revealing a more convincible model. The future research should be focused on the sex differences, the exact location of the gene affecting the sexual orientation, and so on.
