A very cool and interesting article describing the work of Christoph Adami and Arend Hintze (a Michigan State University professor and his protege) highlight how the Prisoner's Dilemma shows that when people are selfish, they will not survive.
The article from Popular Science online, entitled Evolution Punishes Selfish People, Game Theory Study Says explains how this Michigan State duo performed an analysis of what happens in Game Theory's Prisoner's Dilemma - knowing players should cooperate with each other to get the best amount of resources and split them, players will actually act in self-interest, trying to create the best possible payoffs for themselves.
The study published by Nature Communications highlights "zero-determinant" strategies. In this scenario, although in the short-run it may benefit a player to use an "aggressive" strategy, in the long run when all there exists are aggressive opponents, there will be no gains, just an unfair distribution of assets.
This actually sounds more like the Predator-Prey scenario to me, but it relates to Prisoner's Dilemma since when the prisoners cooperate with each other, they both receive a lighter sentence than if they defect on each other. The problem occurs when the prisoners both act in self-interest - they end up ratting each other out to avoid the max sentence of 5 years and try to get no time in jail.
