An Evolutionary Framework for Understanding Coercion and Aggression
This chapter proposes an evolutionary framework for understanding the link between social exclusion and deep marginalization in the development of aggression and violence. It argues that (1) the evolution of language in the primate lineage provides unique capabilities for forming social groups and communities and also defining and signaling exclusion, marginalization, and social rejection; and (2) exclusion and marginalization in humans have historically been salient predictors of mortality and are evocative of self-organization into deviant social groups. The life history perspective offers a macrolevel explanation of the developmental cascade from early childhood defiance to more serious antisocial behavior and violence. An evolutionary framework also provides perspective about which interventions are most likely to be effective at specific points in development and which are potentially limited in effectiveness, or worse, iatrogenic.
