One solution to this partner choice dilemma entails estimating one's fitness interdependence with others. Previous studies indicate that estimates of fitness interdependence (i.e., perceived shared fate) motivate cooperation, but the sources of information that contribute to perceived shared fate remain an elusive question. We examine links among ten sources of interdependence (i.e., attributes and experiences that yoke partners' fitness), perceived shared fate, and cooperation towards three relationship targets (an acquaintance, cousin, and sibling) in a small-scale horticultural society of Northern Nicaragua. While eight sources of interdependence showed positive bivariate associations with perceived shared fate, only relatedness, commensality, and shared subsistence activities were uniquely associated with higher perceived shared fate. Moreover, perceived shared fate (1) was associated with more cooperation across seven fitness-relevant domains, (2) statistically mediated associations between relatedness and cooperation (Study 1: <em>N</em> = 146, Obs. = 437), and (3) had strong effects on cooperation (i.e., forgoing money to buy rice for a partner; Study 2: <em>N</em> = 36, Obs. = 108). Results indicate that perceived shared fate arises from sources of fitness interdependence and cooperation is proximally guided by perceived shared fate. Estimates of fitness interdependence by way of perceptions of shared fate may therefore offer a simple solution to partner choice dilemmas: Help partners if one has a positive stake in their welfare.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"47 1","pages":"Article 106802"},"PeriodicalIF":3.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145571508","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}

Here, we investigate the potential evolutionary roots of visual communication by examining the role of facial displays in sexual interactions in bonobos (<em>Pan paniscus</em>), a species in which - unlike many others - sexuality serves both reproductive and social functions. Using high-resolution temporal analyses, we tested whether variations in the rate of the oscillatory movements during sex (a proxy for sexual stimulation intensity) are associated with the exchange of facial expressions, specifically silent bared-teeth (SBT) displays and rapid facial mimicry (RFM). Analyses of sexual sessions free from interference by third-parties revealed that the offset of unilateral SBTs was not followed by a significant decrease in the oscillatory movement rates, whereas the termination of RFM consistently triggered a decline in sexual stimulation. Restricted temporal windows surrounding RFM cessation further confirmed that disruption of facial mimicry by even one partner suffices to decrease stimulation intensity. These results indicate that RFM, rather than passive observation of a partner's expression, marks the peak of sexual stimulation and reflects fine-grained socio-emotional coordination between partners. Our findings suggest that rapid facial exchanges during sexual interactions in bonobos may represent an evolutionarily conserved mechanism linking nonverbal communication and coordination in social actions. This work provides comparative insights into the communicative functions of facial expressions, highlighting parallels between humans and one of our closest phylogenetic relatives.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"47 1","pages":"Article 106786"},"PeriodicalIF":3.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145369816","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 particular, little is known about how gendered strategies adapt during periods of rapid social and economic changes. To this end, we examine gender differences in scale and composition of ego-networks, guided by two main hypotheses: that gender roles are shaped by (i) market participation, and (ii) post-marital residence pattern. Using data from 1169 married women and men across 14 Tibetan villages undergoing economic and kinship-system transitions, we applied Bayesian multilevel models to analyse core social relationships. Our findings show that, as men increase their participation in market economies, their networks become more kin-centred – strengthening biological kin ties while loosening friend ties – reflecting an instrumental restructuring of social relationships in response to changing economic roles. In contrast, women's networks remain largely unaffected, likely reflecting the persistence of caregiving responsibilities and strong local embeddedness. Post-marital residence patterns impose comparable trade-offs for both sexes: philopatric individuals prioritise biological kin, while affinal kin can effectively substitute for natal relatives when biological kin become less accessible, forming a balanced, bilateral cooperative network that integrates both kin types. This study underscores that women sustain stable and cohesive social ties across socio-economic transitions, while men adapt their networks more flexibly in response to shifting economic roles.</div></div>","PeriodicalId":55159,"journal":{"name":"Evolution and Human Behavior","volume":"47 1","pages":"Article 106814"},"PeriodicalIF":3.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145736734","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 found each dimension loaded positively onto latent lassitude perception, consistent with our hypothesis that these dimensions tap unique but related constructs. Participants' sex predicted their latent lassitude perception, with females showing higher accuracy than males. Our findings suggest there are sex differences in sick face perception, much like the perception of other nonverbal expressions.
