what info does phylogenetic tree provide
A phylogenetic tree or evolutionary tree is a branching diagram or  tree  showing the inferred evolutionary relationships among various biological species or other entitiesâtheir phylogeny âbased upon similarities and differences in their physical or genetic characteristics. A Dahlgrenogram is a diagram representing a cross section of a phylogenetic tree. 2  A phylogenetic network is not strictly speaking a tree, but rather a more general graph, or a directed acyclic graph in the case of rooted networks.
