An rather timely bit of research:

"New research has challenged the notion that evolution favours self-interest above co-operation, suggesting instead that selfish individuals eventually compete each other out of existence.
The study, published in the journal Nature, used models of evolutionary game theory (EGT) to show how co-operative populations are more successful than selfish ones in the long run.
Researchers used computers to play through vast numbers of games simulating scenarios of co-operation and betrayal. By tweaking the strategies of the virtual players they were then able to compare which behaviours resulted in survival.
The study pitched players following so-called zero determinant strategies (those who acted selfishly) against others taking more benevolent approaches. While the selfish strategists enjoyed a brief advantage, opponents eventually came to recognise and overcome selfish individuals.
Communication is critical for cooperation we think communication is the reason co-operation occurs, said Christoph Adami, a professor at Michigan State University and the lead author of the paper. In an evolutionary setting, with populations of strategies, you need extra information to distinguish each other.
We found evolution will punish you if youre selfish and mean. For a short time and against a specific set of opponents, some selfish organisms may come out ahead. But selfishness isnt evolutionarily sustainable.
