Evolution-oriented ethology, kin selection, and altruistic parasites.
The genetic theory of social behaviour challenges ethology to incorporate the study of invertebrates and lower animals; to search for behaviour mechanisms that contribute to the maximization of "inclusive fitness" (rather than to the maintenance of the individual and the species); and to intensify the study of social consequences and interindividual differences in species-specific behaviour.
