The genetic evolution of altruism (ie, a behavior resulting in a net reduction of the survival
and/or reproduction of an actor to benefit a recipient) once perplexed biologists because it …

Spatial self‐structuring has been a focus of recent interest among evolutionary ecologists.
We review recent developments in the study of the interplay between spatial self‐structuring …

In constructing improved models of human behavior, both experimental and behavioral
economists have increasingly turned to evolutionary theory for insights into human …

This is a masterly theoretical treatment of one of the central problems in evolutionary
biology, the evolution of social cooperation and conflict. Steven Frank tackles the problem …

In both biology and the human sciences, social groups are sometimes treated as adaptive
units whose organization cannot be reduced to individual interactions. This group-level view …

Limited dispersal is often thought to facilitate the evolution of altruism by increasing the
degree of relatedness among interacting individuals. Limited dispersal can have additional …

Hamilton's inclusive fitness rule shows that the evolution of altruism is facilitated by high
genetic relatedness of altruists to their beneficiaries. But the evolution of altruism is inhibited …

Group selection can overcome individual selection for selfishness and favour altruism if
there is variation among the founders of the spatially distinct groups, and groups with many …

There has been extensive theoretical debate over whether population viscosity (limited
dispersal) can favour cooperation. While limited dispersal increases the probability of …

It is now widely appreciated that competition between kin inhibits the evolution of altruism. In
standard population genetics models, it is difficult for indiscriminate altruism towards social …
