项目摘要

The history of life on earth has been dominated by a series of cooperative transitions in biological organisation, in which lower-level entities have banded together to form higher-level cooperative groups. The evolution of cooperation creates opportunities for productive coordination and teamwork within groups, but also the potential for destructive conflict and violence between groups. Humans, for example, are capable of astonishing feats of altruism and cooperation, but are at once among the most murderous and violent animals we know. In other animals there is great variation in the intensity and form of intergroup conflict, but we have a very poor understanding of the causes of this variation. The link between intergroup conflict and cooperation is also unclear: in some species intergroup conflict leads to greater social cohesion, whereas in other species it leads to greater within-group aggression. Our project combines new theory and empirical testing to explain these conflicting observations and to advance conceptual understanding of the biological roots of intergroup conflict. Our theoretical models will predict the ecological and social factors that promote or inhibit intergroup aggression, and how individuals and groups should respond to changes in levels of intergroup conflict. We will carry out the first tests of these models on an ideally suited wild mammal system, the banded mongoose Mungos mungo, which we have studied for 20 years at site in Uganda. Banded mongooses live in highly cooperative, territorial groups which engage in frequent intergroup fights. Intergroup aggression is more severe in banded mongooses than in meerkats, chimpanzees, or any other non-human mammal. Yet there is also great individual and group variation in levels of intergroup aggression, providing an opportunity to test our theoretical predictions using experiments and long-term observations. The research will provide a better understanding of patterns of competition in nature, and clarify the link between intergroup conflict and cooperation. We will leave a testable theoretical framework that can be applied to a very wide range of species, from microbes to humans. The project will be of much interdisciplinary interest, with the potential to influence future research in evolution, psychology, economics and political science.

地球上生命的历史一直被生物组织中的一系列合作转变所主导，在这些转变中，较低级别的实体联合起来形成较高级别的合作团体。合作的演变为群体内富有成效的协调和团队合作创造了机会，但也带来了群体之间破坏性冲突和暴力的可能性。例如，人类能够做出令人惊讶的利他主义和合作壮举，但同时也是我们所知的最凶残和最暴力的动物之一。在其他动物中，群体间冲突的强度和形式存在很大差异，但我们对这种差异的原因知之甚少。群间冲突与合作之间的联系也不清楚：在某些物种中，群间冲突会导致更大的社会凝聚力，而在其他物种中，它会导致更大的群内攻击。我们的项目结合了新的理论和实证检验来解释这些相互矛盾的观察，并推进对群体间冲突的生物学根源的概念性理解。我们的理论模型将预测促进或抑制群体间攻击的生态和社会因素，以及个人和群体应如何应对群体间冲突水平的变化。我们将在一个理想的野生哺乳动物系统上对这些模型进行第一次测试，这是一种带状猫鼬Mungos mungo，我们已经在乌干达研究了20年。带斑猫鼬生活在高度合作的领地群体中，经常进行群体间的战斗。群际攻击在带状猫鼬中比在猫鼬、黑猩猩或任何其他非人类哺乳动物中更严重。然而，群体间攻击性的水平也存在很大的个体和群体差异，这为我们提供了一个利用实验和长期观察来检验理论预测的机会。这项研究将使人们更好地理解自然界中的竞争模式，并澄清群体间冲突与合作之间的联系。我们将留下一个可测试的理论框架，可以应用于从微生物到人类的非常广泛的物种。该项目将具有跨学科的兴趣，有可能影响未来在进化，心理学，经济学和政治学方面的研究。
