Simple artificial ecologies are constructed where the interactions between species are defined by an food web. All of the possible actions of the virtual creatures are reduced to moving, mating and eating, to concentrate on the analysis of evolutional dynamics of prey-predator relations. The simulation results show the apostatic selection and surrounding behavior of predators as emergent properties, which are recognized in nature. The conditions of co-existence of species and evolutionary tendencies of visual sense are also analyzed in this paper.
