ON THE EVOLUTION THEORY

Evolutive progress happens in the ambit of a configurational variabili ty determined by the external forces acting on the system, not pre-exi sting to if. The variability obtained is constituted by two components : the one determined directly by the external force (through the elim ination of a symmetry constraint) and the other by the infernal forces developed as system reactions to the consequent modification of the d irectional structure of the forces. In a dynamic system in which only gravitational force act this variability gives rise to the generation of dynamical equilibria, sustained by an adequate masses distribution. The repetition of the process gives rise to a stratified structure of the ordered system, with layers of different rigidify and orientation . Within the first phases the organizational process concernes a limit ed number of configurational variables and is maintained by the extern al force as well as by the resistence of the rigid structures formed b y the aggregation process giving rise to the masses distribution. But, when the structure of the rigidify constraints induced by the masses distribution assumes a certain critical dimension so that the configur ational variables out of the control exerted by the rigidify constrain ts are few, the organizational process permains also in absence of the external force. Furthermore, at every variation of the non controlled variables answers with the assunction of a new ordered condition of e quilibrium. The structures so formed are completely self-organizing.
