[macro- and microevolution as related to the problem of origin and global expansion of the plague pathogen yersinia pestis].the ratio of macro- and microevolutionary processes is considered with reference to the ecological scenario of the origin of the plague pathogen and its subsequent natural and anthropogenic global expansion. the macroevolutionary transformation of the ancestral pseudotuberculosis microbe clone into the initial plague microbe yersinia pestis tarbagani occurred in central asia at the end of the late pleistocene by a "vertical" darwinian way in an inadaptive heterothermal continual intermediate env ...200818773526
[origin of the plague microbe yersinia pestis: structure of the process of speciation].the origin and evolution of the plague microbe yersinia pestis are considered in the context of propositions of modern darwinism. it was shown that the plague pathogen diverged from the pseudotuberculous microbe yersinia pseudotuberculosis o:1b in the mountain steppe landscapes of central asia in the sartan: 22000-15000 years ago. speciation occurred in the tarbagan (marmota sibirica)--flea (oropsylla silantiewi) parasitic system. the structure of the speciation process included six stages: isol ...201622567866
[on the origin of yersinia pestis, a causative agent of the plague: a concept of population-genetic macroevolution in transitive environment].an ecological scenario is proposed for the origin of causative agent of the plague (the bacterium yersenia pestis) from the clone of pseudotuberculous microbe of the first serotype y. pseudotuberculosis o:1b. disclosed are the conditions of gradual intrusion of psychrophile saprozoonosis ancestor into the blood of the primary host, mongolian tarbagan marmot marmota sibirica. as an inductor of speciation acted the sartan cooling that occurred in the end of late pleistocene under conditions of ari ...201526353398
[sympatric speciation of the plague microbe yersinia pestis: monohostal specialization in the host-parasite marmot-flea (marmota sibirica-oropsylla silantiewi) system].an ecological scenario of the origin of the plague microbe that is interpreted in the light of modern darwinism (synthetic theory of evolution) is presented. it is shown that the plague microbe emerged from a clone of the psychrophilic saprozoonotic pseudotuberculosis microbe yersinia pseudotuberculosis o:1b in the mountain steppe landscapes of central asia in the sartan time, 22000-15000 years ago, in the monohostal mongolian marmot (marmota sibirica)-flea (oropsylla silantiewi) host-parasite s ...201627396172
[ecological aspects of evolution of the plague microbe yersinia pestis and genesis of natural reservoirs].a new hypothesis of the origin of the plague microbe in the mongolian bobak (marmota sibirica radde, 1862) populations in central asia during the pleistocene is based on the ideas of its relative phylogenetic recency. the late pleistocene cooling, which induced a deep freezing of the grounds in southern siberia, mongolia, and manchuria, is considered as an inducer of speciation. the main ecological factors of the plague microbe evolution include the species specific behavior of the mongolian bob ...200011147494
