Summary Introduction

Introduction:

Cladistics is the classification of species based on evolutionary relationships. A cladistics approach is used to produce cladogram or phylogenetic tree by considering the possible pathway of evolutionary changes that involve characteristics that are shared or not shared among various species. A cladogram can be used to visualize the groups of organisms being compared, how they are related, and their most common ancestors.
