"Cooperation, despite being now considered the third force of evolution, just behind mutation and natural selection, is difficult to explain in the context of an evolutionary process based on competition between individuals and selfish behaviour. But this puzzle, that has haunted scientists for decades, is now a little closer to be solved by research about to be published on the journal Physical Review Letters. The work, by scientists in Portugal and Belgium, reveals that an increasing range of behaviours among the individuals of a population leads to cooperation, supporting the idea that democracy - where individuals are free to act as they wish - is in fact the path for better societies".

"Van Segbroeck, Pacheco and colleagues’ model reveals that populations in which individuals exhibit higher diversity when handling their social contacts end up being much more cooperative, than those where no such diversity exists. This is particularly interesting if we consider that individuals always behave according to their own narrow-minded preferences and still, despite of this, cooperation blooms".
