BIOLOGICAL AND GENETIC CONTRIBUTORS TO VIOLENCE - WIDOMS UNTOLD TALE

In her review of the literature on the intergenerational transmission of violent behaviors, Widom (1989a) addressed the social issues but omitted all references to the relevant biological and genetic literature. This addition to her review introduces studies of criminality, delinquency, and violence from a behavioral genetic standpoint. There is clear evidence for a genetic role in criminality and for a physiological basis for violent behavior. The inclusion of such genetic and biological evidence is necessary for a more complete understanding of the transmission of violence from one generation to another.
