The core concept of EGT is the . A strategy is an ESS if, once it is adopted by a population, no alternative "mutant" strategy can invade it. Consider the classic Hawk-Dove game: Hawks always fight for resources. Doves retreat if a fight starts. Under strict Darwinian evolution, an animal that sacrifices
