This is the first of a planned series of three papers in which the authors attempt to combine evolutionary migration models with stochastic utility theory. This first paper deals with the evolution of migratory systems. Such systems are first defined, and the foundations upon which their evolution is based are described. The paper concludes with a discussion of disequilibrium, which is central to the series. "Disequilibrium is related to the concept of a steady state, the existence of which is established for nonlinear migratory systems of the type discussed here."
