  • Inter-Group Cooperation in Humans and Other Animals
    Inter-group cooperation in humans and other animals Biology Letters: Author Pre-print Elva J. H. Robinson1 and Jessica L. Barker2 1. University of York, Department of Biology and York Centre for Complex Systems Analysis 2. Aarhus University, Aarhus Institute of Advanced Studies Abstract Social interactions are often characterised by cooperation within groups and conflict or competition between groups. In certain circumstances, however, cooperation can arise between social groups. Here we examine the circumstances under which inter-group cooperation is expected to emerge and present examples with particular focus on groups in two well-studied but dissimilar taxa: humans and social insects. Drivers for the evolution of inter-group cooperation include overarching threats from predators, competitors or adverse conditions, and group-level resource asymmetries. Resources can differ between groups in both quantity and type. Where the difference is in type, inequalities can lead to specialisation and division of labour between groups, a phenomenon characteristic of human societies, but rarely seen in other animals. The ability to identify members of one’s own group is essential for social coherence; we consider the proximate roles of identity effects in shaping inter- group cooperation and allowing membership of multiple groups. Finally, we identify numerous valuable avenues for future research that will improve our understanding of the processes shaping inter-group cooperation. Introduction Across taxa, group-living organisms tend to behave differently towards members of their own group (in-group) than towards members of other groups (out-groups) (Table 1). This characteristically involves two behaviours that are distinct but often co-occur: 1) cooperation with in-group members and 2) conflict with out-groups [1].

  • 1 Cooperation in Adversity: an Evolutionary Approach John Lazarus1 Centre for Behaviour and Evolution, Newcastle University
    Cooperation in adversity: An evolutionary approach John Lazarus1 Centre for Behaviour and Evolution, Newcastle University This is an Author’s Original Manuscript (AOM) of an article published by Taylor & Francis in Global Discourse on 02 January 2018, available online: https://doi.org/10.1080/23269995.2017.1402426. Lazarus, J. (2017) ‘Cooperation in adversity: an evolutionary approach’, Global Discourse, 7:4, 571-598. Abstract: Throughout the organic world cooperation provides mutual benefit but is vulnerable to exploitation from free riders. Over the last thirty years work in evolutionary biology and game theory has provided understanding of the conditions necessary for the maintenance of cooperation, and advances in gene-culture coevolution theory have extended this understanding to our own species. After a preamble on the evolutionary analysis of behaviour I outline this work. I then consider how cooperation is influenced by environmental adversity and find that in non-human species it is enhanced under these circumstances in a range of taxa. In a sample of human cases the same result is found in a majority, but the opposite effect in some when socioeconomic position is the measure of quality. In anthropological studies of societies living in extremis, again the opposite effect is found. I propose a sigmoid shape for the relationship between adversity and fitness (or human well-being) and a consequent inverted-U shaped relationship between adversity and the benefit of cooperation. Most of the data presented on the relationship between adversity and cooperation are consistent with this proposal. I suggest further tests of the proposal and place the study of cooperation in the broader context of prosociality.

  • Group-Level Cooperation in Chimpanzees Is Shaped by Strong Social Ties ✉ Liran Samuni 1,2,3 , Catherine Crockford1,2 & Roman M
    ARTICLE https://doi.org/10.1038/s41467-020-20709-9 OPEN Group-level cooperation in chimpanzees is shaped by strong social ties ✉ Liran Samuni 1,2,3 , Catherine Crockford1,2 & Roman M. Wittig 1,2 Humans maintain extensive social ties of varying preferences, providing a range of oppor- tunities for beneficial cooperative exchange that may promote collective action and our unique capacity for large-scale cooperation. Similarly, non-human animals maintain differ- 1234567890():,; entiated social relationships that promote dyadic cooperative exchange, but their link to cooperative collective action is little known. Here, we investigate the influence of social relationship properties on male and female chimpanzee participations in a costly form of group action, intergroup encounters. We find that intergroup encounter participation increases with a greater number of other participants as well as when participants are maternal kin or social bond partners, and that these effects are independent from one another and from the likelihood to associate with certain partners. Together, strong social relation- ships between kin and non-kin facilitate group-level cooperation in one of our closest living relatives, suggesting that social bonds may be integral to the evolution of cooperation in our own species. 1 Max Planck Institute for Evolutionary Anthropology, 04103 Leipzig, Germany. 2 Taï Chimpanzee Project, CSRS, 01 BP 1303 Abidjan, Ivory Coast. ✉ 3 Department of Human Evolutionary Biology, Harvard University, 02138 Cambridge, MA, USA. email: [email protected]

[email protected] https://www.staff.ncl.ac.uk/melissa.bateson/ Abstract: Integrative explanations of why obesity is more prevalent in some sectors of the human population than others are lacking. Here, we outline and evaluate one candidate explanation, the insurance hypothesis (IH). The IH is rooted in adaptive evolutionary thinking: The function of storing fat is to provide a buffer against shortfall in the food supply. Thus, individuals should store more fat when they receive cues that access to food is uncertain. Applied to humans, this implies that an important proximate driver of obesity should be food insecurity rather than food abundance per se. We integrate several distinct lines of theory and evidence that bear on this hypothesis. We present a theoretical model that shows it is optimal to store more fat when food access is uncertain, and we review the experimental literature from non-human animals showing that fat reserves increase when access to food is restricted. We provide a meta-analysis of 125 epidemiological studies of the association between perceived food insecurity and high body weight in humans.

Assuming an isolated, independently mea- surable culturally transmitted trait, we show that cultural natural selection maximizes cultural fitness, a distinct quantity from genetic fitness, and also that cultural relatedness and cultural altruism are not reducible to or neces- sarily related to their genetic counterparts. We show that antagonistic coevolution will occur between genes and culture whenever cultural fitness is not perfectly aligned with genetic fitness, as genetic selection will shape psychological mechanisms to avoid susceptibility to cultural traits that bear a genetic fitness cost. We discuss the difficulties with conceptualizing cultural change using the framework of evolutionary theory, the degree to which cultural evolution is autonomous from genetic evolution, and the extent to which cultural change should be seen as a Darwinian process.

The examination will be conducted in English. Faculty examiner: Associate Professor Thomas Zeitzoff (American University, School of Public Affairs). Abstract Skoog, E. 2020. Preferences Under Pressure. Conflict, Threat Cues and Willingness to Compromise. Report / Department of Peace and Conflict Research 121. 66 pp. Uppsala: Department of Peace and Conflict Research. ISBN 978-91-506-2805-0. Understanding how preferences are formed is a key question in the social sciences. The ability of agents to interact with each other is a prerequisite for well-functioning societies. Nevertheless, the process whereby the preferences of agents in conflict are formed have often been black boxed, and the literature on the effects of armed conflict on individuals reveals a great variation in terms of outcomes. Sometimes, individuals are willing to cooperate and interact even with former enemies, while sometimes, we see outright refusal to cooperate or interact at all. In this dissertation, I look at the role of threat in driving some of these divergent results. Armed conflict is rife with physical threats to life, limb and property, and there has been much research pointing to the impact of threat on preferences, attitudes and behavior. Research in the field of evolutionary psychology has revealed that threat is not a singular category, but a nuanced phenomenon, where different types of threat may lead to different responses.

Psychology of Intergroup Conflict 2 Abstract The social science literature contains numerous examples of human tribalism and parochialism -- the tendency to categorize individuals on the basis of their group membership, and treat ingroup members benevolently and outgroup members malevolently. We hypothesize that this tribal inclination is an adaptive response to the threat of coalitional aggression and intergroup violence perpetrated by “warrior males” in both ancestral and modern human environments. Here we describe how male coalitional aggression could have affected the social psychologies of men and women differently and present preliminary evidence from experimental social

  • Warfare in an Evolutionary Perspective

Correspondence Bonaventura Majolo, School of Psychology, Some authors hypothesize that warfare emerged at least 200,000–100,000 years BP, University of Lincoln, Sarah Swift Building, was frequent, and significantly shaped human social evolution. Other authors claim Brayford Wharf East, Lincoln LN5 7AT, UK. Email: [email protected] that warfare is a recent phenomenon, linked to the emergence of agriculture, and mostly explained by cultural rather than evolutionary forces. Here I highlight and crit- ically evaluate six controversial points on the evolutionary bases of warfare. I argue that cultural and evolutionary explanations on the emergence of warfare are not alternative but analyze biological diversity at two distinct levels. An evolved propen- sity to act aggressively toward outgroup individuals may emerge irrespective of whether warfare appeared early/late during human evolution. Finally, I argue that lethal violence and aggression toward outgroup individuals are two linked but distinct phenomena, and that war and peace are complementary and should not always be treated as two mutually exclusive behavioral responses.
