CONDITIONS FOR ADAPTATION OF AN EVOLVING POPULATION

We propose a model to study the adaptation of an evolving population t o a given environment. Using the Monte Carlo simulations we find how m uch the phenotypes of individuals of the population and those required by the environment may differ for the population to grow. We show tha t survival chances are greater if the number of the phenotype's featur es is smaller. In the case when a part of the population may colonize an empty niche, we show that there is a minimum value of the similarit y of the two environments in order that such a colonization may succee d. We also show that the two populations differentiate with time.
