Evolutionary psychology considers the human mind to be composed of multiple specific mechanisms with specific adaptive purposes. This evolutionary approach is in line with the domain-specific view of risk-taking behaviors. Based on the theoretical framework of Life History Theory, the present study analyzes the moder-ating effect of gender and the mediating effect of evolutionary domain-specific risks in young adult Spaniards (432 participants). K-factor, measured through the Mini-K, was used as an indicator of life history strategy (LHS). Evolutionary domain-specific risks were measured through the Evolutionary Domain-Specific Risk Scale and risk- taking behaviors through the Risky Behavior Questionnaire. Results showed an interaction effect between gender and LHS for rule breaking. Evolutionary domain-specific risks had a mediation effect between LHS and risk- taking behaviors, mainly through mate attraction. These results highlight the different effects of LHS on risk- taking behaviors based on gender and the impact of evolutionary mechanisms. It is, therefore, necessary to consider an evolutionary approach on intervention programs aimed at reducing risk-taking behaviors in young adults.
