An Evolutionarily Stable Strategy (ESS) is a concept from evolutionary game theory that describes a strategy that, if adopted by a majority of a population, cannot be invaded by any alternative strategy that is initially rare. The concept was first introduced by the biologist John Maynard Smith in the 1970s as a way to explain stable behavioral patterns in animal populations.
