Since Darwin proposed that human musicality evolved through sexual selection, empirical evidence has supported intersexual selection as one of the adaptive functions of artistic propensities. However, intrasexual competition has been overlooked. We tested their relative importance by investigating the relationship between the self-perceived talent/expertise in 16 artistic and 2 sports modalities and proxies of intersexual selection and intrasexual competition in heterosexuals. Participants were 82 Brazilian men, 166 Brazilian women, 146 Czech men, and 458 Czech women. Factor analysis revealed five factors: (...) Literary-arts, Visual-arts, Musical-arts, Circus-arts, and Sports. Multivariate General Linear Model showed more associations of the arts to intersexual selection in women and to intrasexual selection in men, and overall more relationships in women than in men. In women, literary and musical-arts were related to elevated inter- and intrasexual selections proxies, visual and circus-arts were related to elevated intersexual selection proxies, and sports were related to intrasexual selection proxies. In men, literary-arts and sports were related to elevated inter- and intrasexual selection proxies, musical-arts were related to intrasexual proxies, and circus-arts were related to intersexual proxies; visual-arts did not have predictors. Although present in both sexes, each sexual selection component has different relative importance in each sex. Artisticality functions to attract and maintain long/short-term partners, and to compete with mating rivals. (shrink)

By conceptualizing Sexual Selection, Darwin showed a way to analyze intra-specific individual differences within an evolutionary perspective. Interestingly, Sexual Selection is often used to investigate the origins of sports, arts, humor, religion and other phenomena that, in several languages, are simply called “play.” Despite their manifested differences, these phenomena rely on shared psychological processes, including playfulness. Further, in such behaviors there is usually considerable individual variability, including sex differences, and positive relationship with mating success. However, Sexual Selection is rarely applied (...) in the study of play, with exception to what is concerned as infant training behavior for adult sex roles. We offer an integrated grounding of playful phenomena aligning evolutionary propositions based on sexual selection, which might stimulate further exploration of playfulness within evolutionary perspective.

This article considers the application of sexual selection theory to the study of religion by discussing the basic concepts and theories in sexual selection and then outlines possibilities of its application to the study of the evolution of religion. The first section outlines basic principles in the sexual selection account, including the evolution of human mating strategies based on dimorphism, gender differences in human mating strategies, and the role of different cultural activities in mating dynamics. Such an overview may be (...) useful for the readers who are less familiar with the basic assumptions of the sexual selection theory. The remaining sections demonstrate how religion may function as a signal for mating qualities associated with a long-term mating strategy and how different facets of religiosity may help to support long-term mating strategies. The key idea of the article is that there are good reasons to try to explain the evolution of at least some of the components of religion in terms of sexual selection. (shrink)
