title: Social evolution: the smell of cheating.
abstract: Coercion is a powerful means to enforce altruism and promote social cohesion in animal groups, but it requires the reliable identification of selfish individuals. Experiments in a desert ant provide the first direct proof that a single cuticular hydrocarbon elicits the policing of reproductive workers by other colony members.
