Abstract: The present paper summarizes the kinds of molecular information applied in the molecular phylogenetic studies of amphibians and reptiles,and introduces the published articles on molecular phylogenetics of frogs,toads,turtles,lizards and snakes.In these studies mtDNA sequences were mainly used,some nuclear DNA sequences were also applicable.Phylogenetic relationships among higher categories (orders and families) and among genera,species,and subspecies or populations were involved in these studies.
