Abstract

We present the results of morphology–behavior predator–prey coevolution in a 3D physically simulated environment. The morphology and behaviors of virtual creature predators and prey are evolved using a genetic algorithm and random one-on-one encounters in a shared environment. We analyze the evolutionary dynamics on the basis of quantitative characterization of morphology and behavior. Specifically, we pose and answer the question: which precede the other, morphology or behavior, during the evolutionary acquisition of predator and prey strategies?
