Summary Introduction

To review:

The following:

1. The root as well as the outgroup and the differences between the outgroup organism and others.

Introduction:

A diagram that represents the evolutionary relationships among different organisms constitutes a phylogenetic tree. The construction of a phylogenetic tree requires information on homologous, analogous traits and other molecular evidence that can be used to establish relationships.
