Social Evolution: The Smell of Cheating
Chapuisat, M. (2009). Social Evolution: The Smell of Cheating. Current Biology, 19 (5): R196-R19.
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.
