This Review highlights how we can build upon the relatively new and rapidly develo**
field of research into bacterial quorum sensing (QS). We now have a depth of knowledge …

Hamilton's rule is a central theorem of inclusive fitness (kin selection) theory and predicts
that social behaviour evolves under specific combinations of relatedness, benefit and cost …

Comparative studies of social insects and birds show that the evolution of cooperative and
eusocial breeding systems has been confined to species where females mate completely or …

Most theories used to explain the evolution of eusociality rest upon two key assumptions:
mutations affecting the phenotype of sterile workers evolve by positive selection if the …

Social evolution is a central topic in evolutionary biology, with the evolution of eusociality
(societies with altruistic, non-reproductive helpers) representing a long-standing …

Until recently, inclusive fitness has been widely accepted as a general method to explain the
evolution of social behavior. Affirming and expanding earlier criticism, we demonstrate that …

Evolutionarily stable strategy (ESS) analysis pioneered by Maynard Smith and Price took off
in part because it often does not require explicit assumptions about the genetics and …

When two entities cooperate by sharing resources, one relinquishes something of value to
the other. This apparent altruism is frequently observed in nature. Why? Classical treatments …

Opposite phenotypic and behavioural traits associated with copy number variation and
disruptions to imprinted genes with parent-of-origin effects have led to the hypothesis that …

Kin selection theory predicts that, where kin discrimination is possible, animals should
typically act more favorably toward closer genetic relatives and direct aggression toward …
