Interactions among living organisms, from bacteria colonies to human societies, are
inherently more complex than interactions among particles and non-living matter. Group …

We review the theory of public goods in biology. In the N-person prisoner's dilemma, where
the public good is a linear function of the individual contributions, cooperation requires some …

The study of strategic action (game theory) is moving from a formal science of rational
behavior to an evolutionary tool kit for studying behavior in a broad array of social settings …

Despite the depiction of nature" red in tooth and claw", cooperation is actually widespread in
the animal kingdom. Various types of cooperative behaviors have been documented in …

The origin of cooperation is a central challenge to our understanding of evolution,,. The fact
that microbial interactions can be manipulated in ways that animal interactions cannot has …

Ecology Letters (2011) 14: 1300–1312 Abstract We review recent work at the interface of
economic game theory and evolutionary biology that provides new insights into the …

Social behavior has long puzzled evolutionary biologists, since the classical theory of
natural selection maintains that individuals should not sacrifice their own fitness to affect that …

Microbes providing public goods are widespread in nature despite running the risk of being
exploited by free-riders. However, the precise ecological factors supporting cooperation are …

Social dilemmas are an integral part of social interactions. Cooperative actions, ranging from
secreting extra-cellular products in microbial populations to donating blood in humans, are …

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 …
