Across vertebrate species, intergroup conflict confronts individuals with a tension between group interests best served by participation in and personal interest not participating. Here, we identify the neurohormone oxytocin as pivotal to neurobiological regulation of this distinctly different group-living vertebrates, including fishes, birds, rodents, non-human primates humans. In context conflict, review emerging work on pro-sociality suggests that its fish birds homologues, isotocin mesotocin, respectively, can elicit aggression. This is because it amplifies (i) concern for genetically related or culturally similar ‘in-group’ others (ii) willingness defend against outside intruders enemy conspecifics. range social induce aggressive behaviour ‘tend-and-defend’ in-group during contests. article part theme issue ‘Intergroup across taxa’.

Sociality is widespread among animals, and involves complex relationships within between social groups. While intragroup interactions are often cooperative, intergroup typically involve conflict, or at best tolerance. Active cooperation members of distinct, separate groups occurs very rarely, predominantly in some primate ant species. Here, we ask why so rare, what conditions favour its evolution. We present a model incorporating intra- local long-distance dispersal. show that dispersal modes play pivotal role the evolution interactions. Both processes drive population structure, costs benefits tolerance cooperation.

Humans operate in groups that are oftentimes nested multilayered collectives such as work units within departments and companies, neighborhoods cities, regions nation states.

Abstract The human species presents a paradox. No other possesses the propensity to carry out coalitionary lethal attacks on adult conspecifics coupled with inclination establish peaceful relations genetically unrelated groups. What explains this seemingly contradictory feature? Existing perspectives, “deep roots” and “shallow of war theses, fail capture plasticity intergroup behaviors, spanning from cooperation warfare. By contrast, article argues that peace have both deep roots, they co‐evolved through an incremental process over several million years. On one hand, humans inherited for violence their chimpanzee‐like ancestor. Specifically, having first skills engage in cooperative hunting, gradually repurposed such capacity execute killings subsequently enhanced it tech`nological innovations like use weapons. underwent cumulative cultural evolution and, subsequently, self‐domestication which led heightened communication increased prosocial behavior within between combination these two biocultural evolutionary processes—coupled feedback loop effects Pleistocene environmental variability—considerably broadened behavioral repertoire, thereby producing distinctive conflictual characterizes our species. To substantiate argument, synthesizes integrates findings variety disciplines, leveraging evidence anthropology, primatology, archeology, paleo‐genetics, paleo‐climatology.

Abstract There have been recent calls for wider application of generative modelling approaches in applied social network analysis. These motivated by the limitations contemporary empirical frameworks, which generally relied on post hoc permutation methods that do not actively account interdependence data. At present, however, it remains difficult typical end-users—e.g., field researchers—to apply models, as there is a dearth openly available software packages make such simple other, permutation-based methods. Here, we outline STRAND R package, provides suite models Bayesian analysis human and non-human animal data can be implemented using simple, base syntax. To facilitate ease-of-use, provide tutorial demonstrating how used to model binary, count, or proportion stochastic blockmodels, relations combination two frameworks.

Abstract Background Living in a social dominance hierarchy presents different benefits and challenges for dominant subordinate males females, which might turn affect their cognitive needs. Despite the extensive research on group‐living species, there is still knowledge gap regarding how status impacts brain morphology abilities. Methods Here, we tested male female dominants subordinates of Neolamprologus pulcher , cichlid fish species with size‐based hierarchy. We ran three executive function tests flexibility (reversal learning test), self‐control (detour working memory (object permanence followed by region size measurements. Results Performance was not influenced or sex. However, exhibited brain–body slope that relatively steeper than subordinates. Furthermore, individual performance reversal detour correlated morphology, some trade‐offs among major regions like telencephalon, cerebellum, optic tectum. Conclusion As individuals’ growth strategies varied depending without affecting functions, associated yield potential effect cognition instead. Overall, findings highlight importance studying just to understand better individual's ecology shape its cognition.

When defending against hostile enemies, individual group members can benefit from others staying in the and fighting. However, individuals themselves may be better off by leaving avoiding personal risks associated with While fleeing is indeed commonly observed, when why defenders fight or flee remains poorly understood addressed here three incentivized preregistered experiments (total n = 602). In stylized attacker-defender contest games which could stay leave, we show that less costly is, more likely are to abandon their group. addition, risk-averse leave. Conversely, they have pro-social preferences fellow cannot those who not always contribute fully defense, some degree free-riding on efforts of other members. Nonetheless, increased intergroup conflict its costs. meet groups, choose whether defend leave behind. Here, authors predict while predicted concerns for costs risk.
