He is known for his own evolutionary theory, nomogenesis (a form of orthogenesis incorporating mutationism) as opposed to the theories of Darwin and Lamarck. Life Lev Berg was born in Bessarabia in a Jewish family, the son of Simon Gregoryevich Berg, a notary, and Klara Lvovna Bernstein-Kogan. He graduated from the Second Kishinev Gymnasium in 1894.

He later studied ichthyology and in 1928 was awarded he was also a member of the Russian Academy of Sciences. Lev Berg graduated from the Moscow State University in 1898. Between 190 ...

Abyssocottinae
The Abyssocottinae are a subfamily of ray-finned fishes in the family Cottidae, the sculpins. They are known commonly as the deep-water sculpins.Froese, R. and D. Pauly. (Eds.Abyssocottidae.FishBase. 2011. The entire family is endemic to Lake Baikal in Siberia.Hunt, D. M., et al. (1997)Molecular evolution of the cottoid fish endemic to Lake Baikal deduced from nuclear DNA evidence.''Molecular Phylogenetics and Evolution'' 8(3), 415–22. Sculpins of this subfamily mostly live in deep water, below . There are 24 known species in seven genera. These include, for instance, '' Abyssocottus korotneffi'' and ''Cottinella boulengeri'' which are among the deepest-living freshwater fish. Baikal is the deepest lake on Earth () and sculpins occupy even its greatest depths. Evolution and systematics Molecular studies based on mitochondrial DNA suggest that the Abyssocottinae along with other Lake Baikal cottoid fishes, now attributed to the likewise endemic Cottocomephorinae (Baikal scul ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
