Phytospreading Proposed by S.V. Meyen as a Factor of Biological Evolution

Phytospreading, proposed by S.V. Meyen, depends on the role of biological evolutionary “mechanisms”.Some biological species that occupy a vast territory from the equator to the mid latitudes break up into two areas and form two populations. Later, the conditions arise for these populations (new related species) convergence at equatorial or middle latitudes, resulting in the hybridization of…
