项目摘要

The evolution of cooperation is one of the great puzzles of biology and lies at the heart of current attempts to understand the evolution of complex life, from teams of replicating molecules through to cooperative animal societies. One major theory is that sufficiently intense conflict between groups can promote cooperation and altruism within them. In humans, cooperation may have arisen as a consequence of intense warfare among our prehistoric ancestors, a pattern also proposed to explain cooperation in animal societies as diverse as ants and chimpanzees. Yet nature also shows us that cooperation and peace between distinct groups is possible, both in biological systems (as seen in peaceful bonobos, social amoeba, and between maternal and paternal genes in a fertilized egg) and in small-scale human societies, via trade and technological exchange. An outstanding challenge is to identify the factors that explain these varied patterns of conflict and cooperation between groups, each comprised of individuals with different interests and incentives. I will use a uniquely suited termite species, in which colonies engage in both fatal combat and peaceful fusion, to uncover the factors that drive the evolution of war and those that promote peace.Combining carefully controlled experiments in the lab with observations of natural termite colonies in the wild, I will perform the first test of hypotheses proposed to explain patterns of war and peace in humans and other animals. First, I will determine the causes of intergroup conflict and colony fusion by testing how (i) wealth and inequality, (ii) the potential for trade, and (iii) a common enemy, shift colonies between conflict and peace. Second, I will establish the consequences of fighting and fusing for individual behaviour and success, and colony productivity. Finally, I will develop new theory that unites my experimental findings and allows me to explore the effect of these factors acting together, generating general predictions that are testable across a range of species.Intergroup conflict and cooperation are of great biological and human interest, given our own evolutionary history of warfare and cooperation. The combination of theory and experiments at the heart of my project has interdisciplinary relevance beyond biology, particularly in the fields of psychology, economics, sociology, and political science. My research will provide fundamental insights into the forces that suppress conflict and promote cooperation between groups. These insights will be the first step to establishing if peaceful relationships and social integration at the group level can facilitate the evolution of increased social complexity.

合作的进化是生物学最大的谜团之一，也是当前试图理解复杂生命进化的核心，从复制分子的团队到合作的动物社会。一个主要的理论是，群体之间足够激烈的冲突可以促进他们内部的合作和利他主义。在人类中，合作可能是我们史前祖先之间激烈战争的结果，这一模式也被用来解释蚂蚁和黑猩猩等各种动物社会中的合作。然而，大自然也向我们表明，不同群体之间的合作与和平是可能的，无论是在生物系统中（如和平的倭黑猩猩，社会变形虫，以及受精卵中的母亲和父亲基因之间），还是在小规模的人类社会中，通过贸易和技术交流。一个突出的挑战是，找出各种因素，解释这些不同的冲突模式和群体之间的合作，每个群体由具有不同利益和动机的个人组成。我将使用一种独特的适合白蚁的物种，其中蚁群既进行致命的战斗，也进行和平的融合，以揭示推动战争演变的因素和促进和平的因素。将实验室中精心控制的实验与野外自然白蚁群落的观察相结合，我将对提出的解释人类和其他动物战争与和平模式的假设进行首次测试。首先，我将通过测试（i）财富和不平等，（ii）贸易潜力，（iii）共同的敌人如何在冲突与和平之间转换殖民地来确定群际冲突和殖民地融合的原因。第二，我将确定战斗和融合对个体行为和成功以及群体生产力的影响。最后，我将发展新的理论，结合我的实验发现，使我能够探索这些因素共同作用的效果，产生可在一系列物种中检验的一般性预测。考虑到我们自己的战争和合作的进化历史，群体间的冲突和合作具有巨大的生物学和人类利益。理论和实验的结合是我项目的核心，具有超越生物学的跨学科相关性，特别是在心理学、经济学、社会学和政治学领域。我的研究将为抑制冲突和促进群体之间合作的力量提供基本见解。这些见解将是第一步，以确定和平的关系和社会融合在群体一级是否可以促进社会复杂性的增加演变。
