Social Evolution: Policing without Genetic Conflict
Insect societies have evolved ways of policing selfish behaviour that arises due to genetic conflicts within the colony. A new case of policing in an ant where colony members are genetically identical highlights the role of colony economics for policing.
متن کاملSocial Evolution: Community Policing in Insects
A recent study shows that, in social insects where workers suppress or 'police' the reproduction of nestmate workers, only a subset of workers act as police. This confirms that policing can serve a collective rather than a selfish interest.
متن کاملSocial Evolution: Cooperation by Conflict
A recent study suggests that aggression between wasps depends upon the costs and benefits of fighting, as determined by the position of individuals in a dominance hierarchy.
متن کاملWorker policing without genetic conflicts in a clonal ant.
In group-living animals, mutual policing to suppress reproduction is an important mechanism in the resolution of conflict between selfish group members and the group as a whole. In societies of bees, ants, and wasps, policing against the production of males by other workers is expected when egg laying by workers decreases the average inclusive fitness of individual group members. This may resul...
متن کاملExperimental evolution of selfish policing in social bacteria.
Cooperative organisms evolve within socially diverse populations. In populations harboring both cooperators and cheaters, cooperators might adapt by evolving novel interactions with either social type or both. Diverse animal traits suppress selfish behaviors when cooperation is important for fitness, but the potential for prokaryotes to evolve such traits is unclear. We allowed a strain of the ...
