Evolutionary game theory and the adaptive dynamics approach have made invaluable
contributions to understanding how gradual evolution leads to adaptation when individuals …

Cooperation is key to prosperity in human societies. Population structure is well understood
as a catalyst for cooperation, where research has focused on pairwise interactions. But …

Understanding the evolution of sociality in humans and other species requires
understanding how selection on social behaviour varies with group size. However, the …

Prosocial behaviours are encountered in the donation game, the prisoner's dilemma,
relaxed social dilemmas and public goods games. Many studies assume that the population …

How should fitness be measured to determine which phenotype or “strategy” is uninvadable
when evolution occurs in a group‐structured population subject to local demographic and …

The evolution of social traits remains one of the most fascinating and feisty topics in
evolutionary biology even after half a century of theoretical research. WD Hamilton shaped …

The modeling of evolutionary game dynamics in finite populations requires microscopic
processes that determine how strategies spread. The exact details of these processes are …

The evolutionary stability of quantitative traits depends on whether a population can resist
invasion by any mutant. While uninvadability is well understood in well-mixed populations, it …

A long-standing question in biology and economics is whether individual organisms evolve
to behave as if they were striving to maximize some goal function. We here formalize this “as …

Direct, indirect and network reciprocity are key mechanisms fostering cooperation in
societies. Though intrinsically interrelated, they are often studied separately. Unravelling the …
