KQED: Nature vs. Nurture

Scientists have identified that nature and nurture can influence a person and who they will become. Nature refers to your innate qualities and genetics and nurture refers to your personal experience and environment. The question is, which factor is more/less dominant? Scientists have already found that in fruit flies, a male’s aggressiveness can be controlled due to  tweaking  a gene on a neuron (can make fruit fly more aggressive or less aggressive). This leads me to believe that aggressiveness and other behaviors ARE controlled by genes. Therefore, a lot of human behavior is also controlled by genes, but may also be aggravated/soothed depending on a person’s experience and environment.

Learning about the effect of genes on a person’s behavior, I am concerned about people abusing this information. i.e. If someone commits a crime, they may easily be able to blame their actions on their genes–something that is out of there control. Therefore, they may be seen as innocent (or a helpless, aggressive person), instead of receiving a punishment that would be given, without this genetic information.

This information would surely change the courtroom and the way people are seen in society.
