É cada vez maior a utilidade cognitiva da estrutura conceitual darwiniana. Mesmo em ciências tão diversas quanto a psicologia e a física quântica, passando por quase todas as disciplinas das humanidades.

Porém, tal processo, além de muito lento, não tem alcançado a devida visibilidade. No Brasil, ainda domina largamente a ideia de que a teoria darwiniana seja algo restrito às ciências da vida.

Com o intuito de tentar remar contra tamanha maré, o IEA promoverá, em 2022, um ciclo de conversas sobre as trajetórias intelectuais de estudiosos da obra de Darwin.

Recent studies have shown that physical and personality characteristics influence the choice of sexual partners. Two theories explaining particular mechanisms of mate choice were proposed. Theory of homogamy suggests that individuals prefer partners with similar personality traits as they have. Such relationships last longer and partners in them tends to be more satisfied. In contrast, theory of complementarity states that people choose mates with opposite personality traits. In this study we want to test these theories by homosexual couples. Main aim of the current study is to test degree of similartity between partners in both morphological and personality traits. Based on studie of the preferences of gays we assume that will prevail the tendency to homogamy. Another assumptions is that couples based on self-similarity will have higher satisfaction than komplementarity pairs. These assumptions will be tested in the Czech Republic and Brazil. These locations were chosen for their distinctive cultural differences and different preception of gender roles among homosexual men. Personality traits will be measured by standardized psychometric methods, physical similarity will be determined by the measurement of body proportions and facial similarity will be established on the basis of subjective evaluation of the evaluators and by geometric morphometrics.

Recent studies show that both physical and personality characteristics influence partner preferences and actual partner choice. Two theories explaining particular mechanisms of mate preferences and choice were proposed: theory of homogamy suggests that people prefer partners with similar physical or personality traits as their own, and in contrast, theory of complementarity states that people choose mates with opposite traits. Studies show that heterosexuals people usually choose mates similar to
themselves, with the exception of dyadic hierarchy (i.e. submissiveness-dominance). As we have showed, in homosexual individuals preferences for the level of physical (dis)similarity in their potential partners is predicted by their preferred level of dyadic hierarchy. Here we want to test possible influence of preferred and actual position on the hierarchical-egalitarian continuum in same-sex relationships on the level of preferred (dis)similarity in personality and physical traits, and also on relationship satisfaction in actual same-sex couples.
