Definition: A term used initially by Darwin to denote a behavior performed by an individual to aid others while apparently increasing its own risk. Unless such behaviors have at least indirect benefits favoring the individual performing them, evolution of such behaviors could not be explained by natural selection. Neo-Darwinian explanations of such behaviors include kin selection and reciprocal altruism.
