A phylogenetic tree or evolutionary tree is a branching diagram or "tree" showing the evolutionary relationships among various biological species or other entities—their phylogeny-- based upon similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree, indicating common ancestry. The term phylogenetic, or phylogeny, derives from the two ancient greek words(phûlon), meaning "genus, species", and (génesis), meaning "origin, source".
