The “good genes” (dual mating strategy) hypothesis posits infidelity allows women to pair the preferred genes of an affair partner with the preferred investment of their primary partner (Gangstad & Thornhill, 1998). The mate-switching hypothesis instead argues infidelity helps women obtain a new mate without a period of deprivation (Buss et al., 2017). To test these hypotheses, we conducted a pre-registered survey of 254 individuals from 19 countries and 6 continents who were previously or currently engaged in infidelity. We measured individuals' perception of their primary partner and their affair partner across four domains: physical attractiveness, personal attractiveness, attractiveness as a co-parent, and overall desirability (mate value). We also asked participants to report their motivations for the affair. Consistent with a dual mating strategy, women experienced stronger physical attraction to their affair partners and stronger parental attraction to their primary partners. Contrary to the mate-switching hypothesis, women did not prefer their affair partners overall, parentally, or personally. There were no significant gender differences in these findings, suggesting strategic dualism in men as well. Our qualitative data revealed a more nuanced story at the individual level, with participants reporting motives consistent with a variety of evolutionarily coherent strategies. While our quantitative results speak to the relevance of the dual-mating hypothesis to understanding infidelity, our findings also suggest that seeking infidelity's primary explanation in either gender is, perhaps, too simple an approach to the issue.</p></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"45 5","pages":"Article 106595"},"PeriodicalIF":3.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1090513824000710/pdfft?md5=17fac63b8dd7bb1c5f853c1541025986&pid=1-s2.0-S1090513824000710-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141539191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These are key questions in the evolutionary social sciences. Recent advances in the field of human genomics have yielded a wealth of evidence that sheds light on these questions, yet the findings and their implications seem to be little known in the evolutionary social sciences. In this paper I aim to bring together these findings while explaining the conceptual and technical background that is often assumed knowledge for reading the primary reports. First, I outline the genomics methodologies that have enabled the relevant findings, such as genomewide association studies and DNA-based heritability estimation. I describe how these methodologies reveal the genetic architecture of traits, and then how this information in turn enables inferences about past selection. The findings show pervasive evidence that the genetic architecture of complex traits has been shaped by negative (purifying) selection, implying that the extant genetic variation in the traits has been maintained by mutation-selection-drift balance. On the other hand, there is no evidence that balancing selection has substantively shaped complex traits, and strong evidence that it has not. Finally, I discuss the implications of these findings for issues such as the dimensional structure of personality variation and the plausibility of psychological life history theory.</p></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"45 4","pages":"Article 106596"},"PeriodicalIF":3.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1090513824000722/pdfft?md5=645cc54ab3f014e3bc9ba1f3bac18fee&pid=1-s2.0-S1090513824000722-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141480991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Older children were more likely to recognize, prefer, learn from, and assign leadership to the prestigious character, and to identify with the subordinate. There were no cross-cultural differences in learning preferences, supporting evolutionary theories that posit a universal bias towards social learning from prestigious individuals. There was variation in leadership preferences; children were the most likely to assign leadership to a prestigious character in more egalitarian Finland, and least likely in more unequal Colombia.
