Bigger brains with team work

According to a study from the Trinity College in Dublin, Ireland, team work may have lead to increasing brain size during the evolution. The researchers used a quite original method to observe the impact of social interactions on brain size. Indeed, they created computer models of artificial organisms with artificial brains. They made them played against each other in competition games like the classic Prisoner's Dilemma. Then, they let them evolve in their model and showed that a cooporative society has bigger brains. This study is very interesting as it provides new elements on our origins by means of a new technologies.
