Molecular phylogeny is the study to analyze and estimate the evolutionary relationship on the molecular basis such as DNA sequencing. This approach has advantages over the classical approach that uses morphology of organisms to study evolution. It is derived from the traditional system of phylogenetics.
Molecular phylogenetics can be efficiently used to revise the traditional classification scheme as it is unambiguous. The molecular phylogenetic analysis is used to make the phylogenetic trees. Since the basis of molecular phylogenetics is DNA which is found in almost all living organisms it can be a better way for revising the traditional classification scheme.
