Evolution A process operating on populations that involves variation among individuals, traits being inheritable , and a level of fitness for individuals that is a function of the possessed traits. In game theory and biology, a strategy that, when possessed by an entire population, results in an equilibrium such that mutation of the strategy can never result in an improvement for an individual. Always Defect is an ESS, while Always Cooperate is not. Experimentation One process by which scientists attempt to understand nature. The resulting data can be used to derive new models of a process or to confirm an existing model.
Experimentation is the complement of theorization .
