Evolutionary game theory is a way of thinking about evolution at the phenotypic level when the fitnesses of particular phenotypes depend on their fre… - John Maynard Smith

Paradoxically, it has turned out that game theory is more readily applied to biology than to the field of economic behavior for which it was originally designed

The theory of games was first formalised by Von Neumann & Morgenstern (1953) in reference to human economic behaviour. Since that time, the theory has undergone extensive development... Sensibly enough, a central assumption of classical game theory is that the players will behave rationally, and according to some criterion of self-interest. Such an assumption would clearly be out of place in an evolutionary context. Instead, the criterion of rationality is replaced by that of population dynamics and stability, and the criterion of self-interest by Darwinian fitness.

It is in the nature of science that once a position becomes orthodox it should be subjected to criticism.... It does not follow that, because a position is orthodox, it is wrong.
