Cesar Lombroso said that all criminals shared some distinctive features like huge eye sockets, enormous jaws, and handle shaped ears. This theory forms part of an old debate of nature versus nurture that still continues in today’s days. Francis Galton’s field basis, “eugenics”, was that inheritance is more important than the environment and education. For him “talent, character, intellect, disposition, and other aspects of "natural ability," as well as physical features, such as height and eye color, are governed by heredity.” Similarly, tendency for vice and criminality are also inherited. However, this concept became disreputable in the 50s because of its association with “with involuntary sterilization laws and Nazi barbarities.” Although

The first scanning study in murderers was performed by a British neuroscientist Professor Adrian Raine. This study was performed in the Golden State, California, because of “"the large numbers of very violent and homicidal individuals,” (Are Murderers…, 2015). He and his team discovered that in the brains of numerous murderers there was a reduced activity in the pre-frontal cortex (area that controls the emotions) and overactivation in the amygdala (area that generates the emotions), which concluded that the murderers’ brains make them more prone to anger, but less able to control …show more content…
For the moment, scientist have only prove that it is real that biological abnormalities are behind people’s reactions; however, there are no proof that a gene actually obliged a person to commit a crime or decide their destiny. On the other hand, there are many psychological theories that explain people’s behavior, and prove that certain outside factors do make people to commit crimes. However, like always, the exception to these rules makes researchers wonder if their theories are correct or nor. Finally, the questions of why a person commits crimes continues the same as it was before—with many doubts and many theories that can be used to try to answer. If there is a biological reason behind a person’s decisions, and there is actually an inhered destiny in people, a chaos would have happened in the world until is proven wrong. Like in the XYY theories, people would test others in order to eliminate the people who carry the gene. There would be no hope to change a person’s
