Human cooperation in groups: variation begets variation
2015

It has also been shown that individuals condition their behaviour on the overall cooperation level of their peers. Yet, little is known about how individuals respond to heterogeneity in cooperativeness in their neighbourhood. Here, we presen…
Evolution of conflict and cooperation in human groups
2018
The scale of human cooperation and conflict is outstanding and evolutionarily challenging to explain. Cooperative and hostile behaviours have deep evolutionary roots and adaptive functions. However, theoretical models differ in how they explain these functions. Thus, my thesis aims to empirically test functional predictions about human cooperation and conflict. These experiments use a behavioural ecological framework, and pay also attention to the effects of social and developmental environments. In the first two chapters, I studied how group composition affects cooperation and individual success, and how people react to information of each other’s cooperative behaviour. I found that cooper…
The joint emergence of group competition and within-group cooperation
2015
Abstract Between-group conflict and within-group cooperation can be seen as two sides of the same coin, coevolving in a group-structured population. There is strong support for between-group competition facilitating the evolution of human cooperative tendencies, yet our understanding of how competition arises is less clear. We show that groups of randomly assembled individuals spontaneously engage in costly group competition, and that decisions promoting between-group conflict are associated with high levels of within-group cooperation. Remarkably, when groups were given the possibility to compete against other groups, net earnings for individuals were higher than when groups were not allow…
