A phylogenetic tree, also called and evolutionary tree, is a tree showing the evolutionary relationships among various biological species or other entities that are believed to have a common ancestor of the descendants, and the edge lengths in some tree correspond to time estimates.
What is Phylogenetics? Phylogenetics is the area of research concerned with finding the genetic connections and relationships between species. The basic idea is to compare specific characters (features) of the species, under the natural assumption that similar species (i.e., species with similar characters) are genetically close. The term phylogeny refers to these relationships, usually presented as a phylogenetic tree1 (see below).
