Essay Biological Explanations of Criminal Behaviour

Good Essays

Crime theories are still in a development stage; it is an evolutionary process that continues to this day. Crime is still a complex and misunderstood phenomenon with no concrete evidence when it comes to human behavior. Throughout time there have been endless amounts of crime theories, few of which revolve around biological explanations. We have Cesare Lombroso and the Positive School who thought that criminals were genetically different from the rest of the general population, that they were biologically aggressive, had criminal traits and/or born as criminals. There is also William Sheldon’s theory of body types, called the somatotype theory, that argued the mesomorph body type to be the most prone to commit crime or deviant behavior. …show more content…

Although he did not take into consideration that many prisoners lift weights while in prison and that the more muscular individuals usually win the fight (Cartwright, 2012). The twin adoption studies were used by behavioral geneticists to identify genetic and environmental influences underlying human behavioral and physical variations. Although there were many detractors of the twin adoption studies themselves and their results. There were troubles finding subjects which lead to a reduced power of result and inconsistency of the methods used for the operation. In contemporary biological explanations there are still works appearing and being developed, such as, the role of DNA, nutrition, body chemistry and ecological factors in human behavior (Gado, 2004). Most of these are either still being developed, like DNA, or were discredited along with the works of Lombroso, like nutrition. Although biological explanations may not have made a momentous improvement since the 18th century, arguments within biological explanations have expanded. There are many theories that argue if human behavior is predetermined at birth, or learned by influences. Nature versus nurture,
