Biological Theories of Crime Causation;
Researchers have used genetics to evaluate the causal arguments used in supporting the biological theory of crime causation. Some of the studies used in supporting the biological theory of crime causation are discussed below.
criminology: Biological theories of crime causation in criminology
The neurological system is critical in controlling an individual’s behavior and perspectives on antisocial behavior or crime. The brain is the center of any individual’s personality, and studies in the biological theory of crime causation analyze various biological factors such as serotonin activity, specific genes, neurological deficit, and other factors such as malnutrition.
The biological theory of crime causation begun in the 1800s and scholars regard Cesare Lombroso as the pioneer researcher in demonstrating a relationship between biological and genetic traits and criminals. Lombroso conducted a study on convicted criminals and used his findings to publish his book titled “Criminal Man” in 1876. Lombroso also developed and refined a method of identifying criminal behavior. In his studies, Lombroso analyzed physical traits of such as brain and skull sizes, physique, shapes of noses and methods of self-expression among criminals through tattoos and graffiti. According to Lombroso, criminals were inferior to non-criminals and were recognizable by physical traits such as cranium asymmetry, sloping foreheads and long arms among others. Lombroso called individuals “atavistic” or throwbacks because they had primitive features.
