As Lawrence Perbal discussed in his article, "The Warrior Gene' and the Mãori People: The Responsibility of the Geneticists", found in the journal Bioethics: Volume 27 Number 7, "many studies have shown a statistical (positive correlation) or causal relationship between low levels of MAOA and aggressive behavior, mental retardation, lack of self-control, addiction, and risk taking behaviors". In a TED Talk done by Jim Fallon, he goes on to explain how those with this monoamine oxidase A gene, have an overflow of serotonin in youth. This may boggle the mind because serotonin has to do with feelings of joy or happiness. However, because of this overdose of serotonin at a young age, these people become tolerant of the serotonin and it no longer has the outcomes it is intended to have (Fallon). As with anything, once tolerant, the ability of serotonin to produce feelings of pleasantry is diminished greatly. Consequently, without the capability of having these pleasing feelings it causes those particular individuals to be more likely to having aggressive outbreaks of brutality and outrage. Jim Fallon also makes a countering point in his Ted Talk, that without a traumatizing event, these genes do not create a criminal. He argues that without a mortifying occurrence, people will live "normal" lives free of violence. Despite this idea or belief, genes do have the strongest ramifications and should be treated as such. The genes create who we are and predestine what we will do and become. Knowing the connections and consequences of these genes and how they alter the way people behave, what responsibility is society left with to prevent these aggressive occurrences from
