Molecular phylogenetics /mÉµËlÉkjÊlÉr ËfaÉªlÉµdÊÉ¨ËnÉtÉ¨ks/ is the branch of phylogeny that analyses hereditary molecular differences, mainly in DNA sequences, to gain information on an organism's evolutionary relationships. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree.Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography.olecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography.
From Wikipedia, the free encyclopedia. A phylogenetic tree based on rRNA data, showing the separation of bacteria, archaea, and eukaryotes. The three-domain system is a biological classification introduced by Carl Woese et al. in 1977 that divides cellular life forms into archaea, bacteria, and eukaryote domains.he three-domain system adds a level of classification (the domains) above the kingdoms present in the previously used five-or-six-kingdom systems.
