For Charles Darwin, the artistic creativity of humans finds parallels with aesthetic manifestations of other animals, such as the song and the ability of some birds to build decorated nests. Why would different species have developed these psychological capabilities? For Darwin, the answer is sexual selection. This thesis is composed of studies that aim to test expected predictions given the possibility that intelligence and creativity in humans have evolved at least partially by sexual selection. The first chapter presents a review integrating evidence in a nomological network to verify if the empirical literature as a whole supports the evolution of creativity by some process linked to sexual selection. The second chapter presents a qualitative study whose objective was to verify if intelligence and creativity would emerge as categories of attractiveness criteria in the face of spontaneous responses from participants about the characteristics of an ideal love partner. The third tests the relationships of sapiosexuality with other psychological variables, while the fourth study tests the relationships of attraction to creative behaviors with other psychological variables. Finally, the fifth study is an experiment whose aim was to test whether intelligence and creativity were attractive in themselves or because of their beneficial social consequences. The results presented in this thesis indicate that intelligence and creativity may have evolved partially by sexual selection, although the specific process (good genes, etc.) may not be clear. Furthermore, empirical studies have shown that women are more sapiosexual and prefer creative partners more than men. Furthermore, the attraction to intelligence and creativity seems to be linked to short-term reproductive strategy.
