"The research team at McGill said the latest research was important because it examined ways society could influence environmental factors to decrease the likelihood of aggressive behaviour."
so the conclusion is we should walk around with a steak tied in front of us?
In terms of the finding - the obvious link I could think of was - historically we needed aggresion to be good hunters. But once you have hunted and have that food ready to eat in front of you - no need to be agressive anymore...
