Biological Influences on Criminal Behavior fundamentally questions the way most criminologists attempt to explain, let alone ameliorate the problem of human criminal behavior. Written by a respected expert in forensics, who also brings a much-needed biological background to the task, this resource champions contemporary biological theory by introducing criminologists to areas of research they might not otherwise encounter. It discusses basic biological concepts such as natural selection and evolution in relation to behavior, and considers patterns of inheritance, sex-linked traits, and propensities toward aggression: explores studies on hormonal effects, as well as brain chemistry, and delves deeply into organic brain dysfunction: and looks at investigations into fetal conditions and birth-related difficulties, as well as research on nutrition and food allergies.
