Phylogenetic trees are relevant to many areas of biological sciences, and thus appear in a wide range of scientific journals. Only a handful of journals (e.g., Trends in Ecology and Evolution and Cladistics), however, regularly contain articles discussing how to interpret phylogenetic trees.
Phylogenetic (evolutionary) Tree • showing the evolutionary relationships among various biological species or other entities that are believed to have a common ancestor. • Each node is called a taxonomic unit. • Internal nodes are generally called hypothetical taxonomic units • In a phylogenetic tree, each node with
Different kinds of trees can be used to depict different aspects of evolutionary history 1. Cladogram: simply shows relative recency of common ancestry 2. Additive trees: a cladogram with branch lengths, also called phylograms and metric trees 3. Ultrametric trees: (dendograms) special kind of additive tree in which the
