Main stages of development of megataxonomy (the science of organic world dividing into large taxa) are considered. Prerequisites and first results of "revolution in megataxonomy" (cardinal reorganization during last years) are analyzed. Matter of "revolution" is considered: changing of main megataxonomic criteria from morpho-physiological to cytological and genetical ones. Advantages of classifications of organic world based on cytological and genetical criteria, and main arguments of their opponents are discussed. Some taxonomic changes based on published data are suggested: the kingdom Lamellitubulicristata (lamellicristate and tubulicristate eukaryots) is created, Cryptophyta, Prymnesiophyta, Percolozoa and Actinozoa are risen up to the kingdom rank. Original megasystem of dominion Eukaryota is build up, including 2 subdominions (Hypochondria and Epichondria), 3 superkingdoms (Hypocrystata, Discocrystata and Lamellitubulicristata) and 14 kingdoms (Archaeomonadobiontes, Microsporobiontes, Euglenobiontes, Percolobiontes, Myxobiontes, Actinobiontes, Alveolobiontes, Chromobiontes, Prymnesiobiontes, Cryptobiontes, Rhodobiontes, Chlorobiontes, Mycobiontes and Zoobiontes). Characters of these taxa and an outline of their evolutionary connections based on published data are provided. |
