The most generally applied method for determining phylogenetic relationships between microorganisms is based on comparative analysis of the 16S rRNA gene sequences (Neefs et al., 1990 ). The main difference between rooted and unrooted phylogenetic tree is that the rooted phylogenetic trees show the ancestry relationship, whereas the unrooted phylogenetic trees only show the relatedness of organisms. The classification was based on the organization of the thallus, the cell structure, the diet, the phylogenetic relationship, and the reproduction. 10. o Explain the benefits of metamerism for an annelid.
