Summary Introduction

A phylogenetic tree is the diagrammatic representation of the evolution of different species. A phylogenetic tree is similar to a tree which has many branches. In a phylogenetic tree, the tip of the branches shows the species and the branching point is genera or most recent common ancestor, the root of the tree is the common ancestor from which all the genera and species evolved. The phylogenetic tree shows how the species are related to one another.
