Speciation and intraspecies adaptive radiation of causative agent of plague -microbe Yersinia pestis as a gradual evolutionary process

In the last two decades the questions of origin and evolution of the plague pathogen Yersinia pestis have become a prerogative of molecular genetics and are mostly addressed in terms of horizontal gene transfer. However, it is impossible to build genealogical trees of any taxons employing only molecular genetics methods. Here, we describe an ecological genetic scenario of plague pathogen origin and evolution. Using the knowledge of many classical biological sciences, we elucidate the principles and structure of gradual evolutionary species formation. The suggested scenario of plague pathogen origin and evolution is in good agreement with the principles of modern Darwinism as a synthetic theory of evolution.
