By allowing the brains of these digital organisms to evolve freely in their model the researchers were able to show that the transition to cooperative society leads to the strongest selection for bigger brains. Bigger brains essentially did better as cooperation increased.

The social strategies that emerge spontaneously in these bigger, more intelligent brains show complex memory and decision making. Behaviours like forgiveness, patience, deceit and Machiavellian trickery all evolve within the game as individuals try to adapt to their social environment.
