Traditionally, evolutionary game dynamics is described in terms of deterministic differential equations. In the past years, evolutionary game dynamics has benefitted from considering finite populations, which adds a natural source of noise. The intensity of selection, which corresponds to an inverse temperature, determines the interplay between selection and noise. Weak selection allows numerous new results in stochastic evolutionary game dynamics, but sometimes also strong selection allows analytical results. Theoretical aspects of this development will be discussed and examples from the evolution of cooperation and punishment will be given, where noise can become crucial for the dynamics.
