The paper analyzes changes in some physical parameters obtained from theoretical, model calculations in several catalogs for Seyfert galaxies of spectral classes S1 and S2. It is concluded that there is a high probability that the existing evolution of Seyfert galaxies occurs from the spectral class S2 to S1.Based on the analysis of a large array of observational material, it is shown.
that the distribution of Seyfert galaxies as a spectral class Sy1. so Sy2 has a bimodal character.
