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.
Overview of phylogenetic trees. In a phylogenetic tree, the species of interest are shown at the tips of the tree's branches. The branches themselves connect up in a way that represents the evolutionary history of the speciesâthat is, how we think they evolved from a common ancestor through a series of divergence (splitting-in-two) events.
