A bacterial phylogenetic tree or evolutionary tree is a diagrammatic representation of the evolutionary relationships among various taxa of bacterias, like Mycobacterium, Cyanobacteria, and others. It is a branching diagram composed of nodes and branches. As the phylogenetic tree diagram suggests, the major components of such trees are leaves. The leaves of a tree can be species, populations, individuals, or even genes. With EdrawMax Online, you can create similar phylogenetic tree diagrams for your usage. The free phylogenetic tree maker offers tons of customization and has a good remote team collaboration. If the tips represent a formally named group, they are called taxa (singular: taxon). A 'taxon' is a group of organisms at any hierarchical rank, such as a family, genus, or species.
