Summary: This book argues for the integration of a biosocial perspective into contemporary explanations of criminality. It shows how existing theories can be better understood, expanded and revised by the incorporation of relevant methodological, conceptual and theoretical insights from the biological sciences. The first four chapters explain why criminology needs biology and describe the three major biosocial perspectives of human behavior (evolutionary psychology, behavior ...show moregenetics and the neurosciences). The remainder of the book goes on to evaluate the propositions of traditionally dominant sociological theories, reflecting on how biosocial concepts and principles might be embraced and utilized. In-depth coverage is given to the differential association/social learning tradition, the human ecology tradition, and critical and feminist theories. The final chapter summarizes the lessons of the book and offers a discussion of ethical concerns.
