Abstract. The main purpose of this paper is to delineate the contemporary development of Game Theory as regards to the evolutionary approach, whose scientific value is due to its interpretative capability of real phenomena both in biologic-genetic and in economic field. In the paper it is shown that these studies, which are based on the idea of "evolutionar(il)y stable strategy" and on "replicator" dynamics, implied the overcoming of the deadlock situation in which Game Theory had come because of the multiplicity of Nash equilibria, in spite of the numerous attempts to analyze a selection process of this type of equilibrium by studying its refinements. In the paper there are also some references to the main mathematical aspects and to interesting applications of this approach to economic contexts.
