Summary: The author criticizes some hypotheses of amphibians and reptiles occurrence and expansion, including those on the basis of data phylogeography interpretation,suggested by herpetologists. Using molecular data, it is impossible to define, where subspecies has appeared and how its area varied. The method of definition of species appearance time requires very serious correlation by means of paleontological data. It is also impossible to identify approximate time of the subspecies occurrence, defined by molecular data, with the time of its modern area occupation. We can assume it, analyzing paleontological findings and paleogeographical conditions at that time, but not vice versa.
