The selective forces that shape and maintain eusocial societies are an enduring puzzle in
evolutionary biology. Ordinarily sterile workers can usually reproduce given the right …

In cooperative breeding systems, some individuals help to raise offspring that are not their
own. While early explanations for such altruistic behaviour were predominantly based on kin …

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

The presence of workers that forgo reproduction and care for their siblings is a defining
feature of eusociality and a major challenge for evolutionary theory. It has been proposed …

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

Over the past several decades, we have argued that cultural evolution can facilitate the
evolution of large-scale cooperation because it often leads to more rapid adaptation than …

Pseudomonas aeruginosa coordinates the transcription of hundreds of genes, including
many virulence genes, through three hierarchically arranged quorum-sensing (QS) systems …

Achieving cooperation between individuals is challenging and often driven by self-beneficial
motives. On the other hand, people also seem capable of subordinating their personal …

This paper argues that besides mechanistic explanations, there is a kind of explanation that
relies upon “topological” properties of systems in order to derive the explanandum as a …

In a recent paper, Traulsen and Nowak use a multilevel selection model to show that
cooperation can be favored by group selection in finite populations [Traulsen A, Nowak M …
