Serotonin Gene Contributes to Aggression and Anger in Women

(And presumably likely in men also)

The study is the first to look at the relationship between variations in the serotonin receptor 2C gene and anger and hostility.

Completed at the University of Pittsburgh’s Behavioral Physiology Laboratory, the study looked at 550 unrelated women of European descent. In order to find normal variations in genes and behavior, the women were not prescreened for behavioral type. Researchers found that those who had one or both of two alterations in the promoter region of the serotonin receptor 2C gene were more likely to score lower on two common tests for anger, hostility and aggression.

These findings may aid in establishing a potential marker for certain conditions associated with aggression and anger. (Source: PhysORG)

So this raises the question for me… What if they started screening for gene variants of this nature in situations in which rapid aggression might be dangerous? Perhaps as a criteria for military or police officer work? Or maybe they’d find that the aggression was beneficial, and only look to hire for that reason.

Then again, I guess that’s why they have laws from preventing genetic screening as an employment criteria. But if this law were to be taken out of place… a whole different kind of evolution may take place, and very rapidly.
