Molecular phylogeny is the use of the structure of molecules to gain information on an organism's evolutionary relationships. The result of a molecular phylogenetic analysis is expressed in a so-called phylogenetic tree.
Molecular phylogeny is the use of a gene's molecular characteristics to classify an organism and to place it on a map of evolutionary relationships known as the phylogenetic tree.
We recently demonstrated that there are at least two ecotypes of Prochlorococcus, each of which is distinguished by its photophysiology and molecular phylogeny. One is capable of growth at irradiances, and the other is not.
