Why would natural selection favor the prevalence of cooperation within the groups of selfish
individuals? A fruitful framework to address this question is evolutionary game theory, the …

Traditionally, the evolution of cooperation has been studied on single, isolated networks. Yet
a player, especially in human societies, will typically be a member of many different …

It is not fully understood why we cooperate with strangers on a daily basis. In an increasingly
global world, where interaction networks and relationships between individuals are …

Recent research has identified interactions between networks as crucial for the outcome of
evolutionary games taking place on them. While the consensus is that interdependence …

Cooperativeness is a defining feature of human nature. Theoreticians have suggested
several mechanisms to explain this ubiquitous phenomenon, including reciprocity …

Biologists have devoted much attention to assortative mating or homogamy, the tendency for
sexual species to mate with similar others. In contrast, there has been little theoretical work …

Economic experiments reveal that humans value cooperation and fairness. Punishing unfair
behavior is therefore common, and according to the theory of strong reciprocity, it is also …

Evolution occurs in populations of reproducing individuals. The trajectories and outcomes of
evolutionary processes depend on the structure of the population. Evolutionary graph theory …

This is an introduction to the special issue titled" Collective behavior and evolutionary
games" that is in the making at Chaos, Solitons & Fractals. The term collective behavior …

Collective actions, from city marathons to labor strikes, are often mass-driven and subject to
the snowball effect. Motivated by this, we study evolutionary advantages of conditional …
