Evolutionary perspective of same-sex sexuality: Homosexuality, and homosociality revisited

Popis výsledku v původním jazyce

From the evolutionary point of view homosexual orientation is a puzzle because same-sex sexual preferences significantly reduce individual reproductive success. In this paper, we reconsider two theories explaining human homosexuality as an extreme of anadaptive trait of bisexuality, and as a by-product of another adaptation which consists in a more general shift of males toward feminine characteristics. In line with these theories, we discuss the issue of male bisexuality, and concept of female fluidity of sexual preferences. Based on the theories, we argue, that opportunistic homosexuality may be adaptive for both men and women within certain social contexts, or in specific periods during individual ontogeny, even if not through direct increase of individual reproductive success. We propose that same-sex sexuality and/or preferences can appear at specific periods during individual's ontogeny, when samesex alliances would be advantageous for the individual. Based on our arguments, opt
