Since Darwin, scientists have sought both proximate and ultimate explanations for how human thinking and information processing differ from those of other species, and why humans evolved such advanced cognitive skills. Research over the past few decades suggests that various aspects of human socioecology—such as large group sizes and intensified social competition driven by ecological dominance—have selected for greater intelligence. However, a clear account of how intelligence enables individuals to adaptively navigate the complex web of social interactions within human groups remains an unsatisfied desideratum. To address this issue, we synthesize insights from psychology, anthropology, cognitive science, and other evolutionarily informed fields to formulate the <em>Coalitional Intelligence Hypothesis</em>. This hypothesis posits that the behavioral manifestations of human intelligence function as honest signals of coalitional value, facilitating adaptive exchanges of status and cognitive–computational services. We derive five testable predictions from this hypothesis and evaluate them against core findings in the literature.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"47 3","pages":"Article 106839"},"PeriodicalIF":3.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146147697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper argues that some of the plant taxa were more likely to have been used as medicines than as foods. Six arguments support the medicinal plant hypothesis: 1. a literature search of major phytochemical and botanical databases (e.g., <em>USDA Dr. Duke's phytochemical and ethnobotanical databases; Kew State of the world's plants</em>) shows that a significant portion of the plant taxa in the assemblage are potentially toxic to humans, suggesting that they were more likely to have had non-dietary than dietary uses; 2. a literature search of major food nutrition databases (e.g., <em>USDA Food Data Central</em>) shows that a significant portion of the plant taxa have low nutritional and caloric value compared to other plant taxa and faunal material in the assemblage, also suggesting that they were more likely to have had non-dietary than dietary uses; 3. a literature search of major botanical databases shows that the proportion of medicinal to non-medicinal plant taxa in the assemblage is significantly higher than global proportions; 4. a literature search of major herbal medicine databases and reference works (e.g., <em>USDA Dr. Duke's phytochemical and ethnobotanical databases</em>; <em>Native American ethnobotany database; Complete German Commission E monographs: Therapeutic guide to herbal medicines</em>) shows that all 55 edible plant taxa in the assemblage have been used as plant medicines in traditional medicine, and most are still in use in contemporary herbal medicine; 5. a literature search of published phytochemical and pharmacological analyses of the 55 edible plant taxa shows that almost all contain medicinally active properties; and 6. the use of plant medicines would have provided significant fitness benefits to the hominins who occupied the site.

In men, sexual infidelity poses risks of paternal uncertainty, whereas in women, emotional infidelity threatens resource diversion. To test evolutionary predictions about sex differences in jealousy responses, the present study employed an improved economic game paradigm with heterosexual couples. Specifically, the modified dictator game was refined to <em>explicitly state</em> that the participant's partner would not only allocate resources to a newly introduced intrasexual rival but also receive resources that the partner would directly accept from this rival, thereby clarifying the intentionality and directionality of the exchange. This adjustment enhances ecological validity by modeling both partner-initiated and rival-initiated threats in a more realistic mate-poaching context. Seventy-nine heterosexual couples participated in a laboratory setting. Controlling for individual differences such as attachment anxiety and digital jealousy, it was hypothesized that women would experience greater jealousy than men when their partner allocated resources to a rival, while men would experience greater jealousy than women when their partner received resources from a rival to the detriment of the rival's partner. Results partially supported these hypotheses: resource allocation to a rival triggered greater jealousy responses in all participants, particularly among women, consistent with emotional infidelity models, whereas the reception condition yielded weaker and less differentiated effects. These findings suggest that allocation-based paradigms effectively model generalized romantic jealousy in partner–rival contexts involving resource exchange but may have limited sensitivity for detecting mate-poaching-related jealousy. More broadly, the study highlights the promise and constraints of economic games for experimentally investigating sex-specific adaptations in emotional responses.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"47 2","pages":"Article 106816"},"PeriodicalIF":3.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145886227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We consider the role of infant cognition—specifically, abstract, early-emerging knowledge about social intimacy that forms part of “core knowledge.” Drawing on theories of cultural attraction, we argue that the common knowledge that arises from this early-emerging knowledge shapes the “basins of attraction” for particular cultural practices. Using romantic kissing as a case study, we build on evidence that even infants interpret physical closeness and behaviors like saliva sharing as signals of intimate social relationships. When romantic love becomes personally or culturally salient, this abstract knowledge makes practices like romantic kissing intuitive to invent, learn, and maintain because they fit pre-existing expectations about how intimacy, more broadly construed, is displayed. We further suggest that variation in the prevalence of romantic kissing depends on the importance placed on romantic love within a culture. Our account provides a framework for understanding both the cross-cultural diversity and recurrent emergence of romantic kissing, and for theorizing about how universal cognitive representations may interact with local social and ecological factors to shape the emergence and form of cultural practices.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"47 2","pages":"Article 106810"},"PeriodicalIF":3.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145886229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To investigate this hypothesis, we conducted two complementary studies. Study 1 tested whether engaging in a game, compared with a non-game interaction (role playing), influences how same-sex strangers perceive each other's value and relational closeness across repeated encounters. Although both constructs changed over time, gaming did not produce stronger or faster shifts than the comparison activity. Study 2 used an agent-based evolutionary model to explore the conditions under which gaming could spread in a population as a tactic for ally selection. The simulations indicated that gaming is favored when players possess above-average skill and when environmental risk coevolves with population skill; otherwise, gaming tends to drift or disappear. Together, these studies suggest that the social effects of gaming are context-dependent and may not emerge uniformly across game types or interaction settings. The modeling results highlight that risk, skill, and reliability of performance cues are key parameters for understanding the potential evolutionary role of gaming in alliance formation. Future work should integrate long-term interactions, participants' skill levels, and different game ecologies to clarify under what circumstances gaming strengthens social bonds.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"47 2","pages":"Article 106833"},"PeriodicalIF":3.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146173261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, we test plausible proxies of parental condition largely ignored by prior investigations: worry about family member mortality and perceptions of community mortality risk. We administered an in-person survey to 302 married women living in Matlab, Bangladesh, and captured both mortality and financial-related proxies of parental condition and three parental bias variables (hypothetical investment in sons vs. daughters, preferences for sons vs. daughters, and the sex ratio of respondents' children). Using Bayesian regression, we found only two of nine of our a-priori predictions were supported: there is a 61 % probability that perceptions of community mortality risk are positively associated with preferring daughters over sons and a 66 % probability that financial standing is positively associated with preferring more sons than daughters. Other tests did not reveal clear effects or revealed an effect opposite to what was expected. However, in line with our TWH-inspired hypotheses, exploratory tests revealed that <em>early life</em> exposure to mortality is positively associated with having more daughters than sons and <em>early life</em> financial standing is positively associated with having more sons than daughters. We conclude that tests of the TWH remain sensitive to how parental condition and bias are operationalized, and that assessments of parental condition earlier in life may be particularly predictive of parental bias patterns in accordance with the Trivers-Willard hypothesis.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"47 2","pages":"Article 106812"},"PeriodicalIF":3.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145842473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
