Stochastic (left) and deterministic (right) simulations of the the model of competition between two species (wild type and mutant for common resource Hallatschek (2011a). Despite the higher growth yield, mutants are only able to invade the wild-type population in the stochastic simulations. Interestingly, the width of the transition region between mutants and wild type remains constant in stochastic simulations but grows in the deterministic case. The parameters of the model are K0 = 30, D = 0.05, ε = 0.01.
