Ecological system modelling is a powerful tool that provides better understanding of interspecies interaction. Although a complex model gives more information about the modelled object it also drastically increases the computational time needed to get that information. In this paper a rather simple three trophic level population dynamics model with an evolution mechanism is described which can be run on any personal computer. The performance capacity of the evolution mechanism was shown by running the model 1100 times for both carnivores and herbivores so that only one type of animals could evolve. Also it was shown that attempts of controlling the population abundances with chemicals or by hunting while being somewhat effective still can be overcome by animals if they have the ability to evolve.
