The Origin of Evolution in Physical Systems

A tentative outline for a model for the evolution of physical systems is presented. The universal classes of dynamical behaviors found in Cellular Automata experiments provide the basis for introducing the variation-stabiliza- tion principle as a synthetic interpretation of these phenomena. It is suggested that biological evolution takes its root in the evolution of physical systems as a particular case of the variation-stabilization principle that occurs at the transi- tion phase between ordered and chaotic regimes.
