Direct reciprocity is a powerful mechanism for the evolution of cooperation based on
repeated interactions between the same individuals. But high levels of cooperation evolve …

Consider a cooperation game on a spatial network of habitat patches, where players can
relocate between patches if they judge the local conditions to be unfavorable. In time, the …

Spatial interactions are considered an important factor influencing a variety of evolutionary
processes that take place in structured populations. It still remains an open problem to fully …

Many evolutionary processes occur in phenotype spaces which are continuous. It is
therefore of interest to explore how selection operates in continuous spaces. One approach …

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

Indirect reciprocity is one of the major mechanisms for the evolution of cooperation in human
societies. There are two types of indirect reciprocity: upstream and downstream …

Darwin's theory of evolution by natural selection has become one of the most influential
theories in biology and adjacent fields [34]. It provided answers to many existing puzzles, but …

The coalescent is a stochastic process representing ancestral lineages in a population
undergoing neutral genetic drift. We introduce an abstract formulation of the coalescent that …

Indirect reciprocity is one of the major mechanisms driving the evolution of cooperation in
human societies. There are two types of indirect reciprocity: upstream and downstream …

Reciprocity is a potent mechanism that drives cooperation within human societies. Direct
reciprocity involves interacting with individuals, while indirect reciprocity is reliant on …
