WebThis paper proposes and analyzes a model of stochastic evolution in finite populations. Our model is a generalization of the Moran process of evolutionary biology (Moran [1962], Ewens [2004]) to frequency-dependent fitness. In this process, one individual per period “dies” and is replaced by a newcomer. The newcomer’s strategy is a
