[Academician A.N. Severtsov and the present time].

Research and teaching activities are of Academician A.N. Severtsov are briefly considered. His scientific heritage is shown to be based on the extensive comparative morphological data on lower vertebrates. The concepts of phylembriogenesis and biological progress elaborated by A.N. Severtsov did not lost their importance as a theoretical and methodological background of the evolutionary morphology as a specific field of zoology dealing with regularities and mechanisms of morphological evolution. Their exploration is of great potential in developments of both epigenetic theory of evolution and particular phylogenetic reconstructions.
