In a recent study conducted by a University of Montreal professor, it was concluded that aggressive behavior in children nowadays is genetic rather than a by-product of violent media as previously assumed with the many issues popping up about violence-related cases due to video games.

Richard Tremblay, a professor of pediatrics, psychiatry and psychology, explains that modern media is still relevant to their development and subsequent behavior; however, there were many recorded incidents of violent youths even before the television appeared.

Tremblay has been tracking over 35,000 Canadian children over the past 20 years and presented his findings earlier this week in London at a meeting of The Royal Society, the UK's academy of science. He sums up his study by saying:

We’re looking at to what extent the chronically aggressive individuals show differences in terms of gene expressions compared to those on the normal trajectory. The individuals that are chronically aggressive have… more genes that are not expressed. [This] is an indication that the problem is at a very basic level.
