Chapter 15, Problem 15TYK
Summary Introduction
To discuss: The types of molecular comparisons that are used to determine the very early branching of the tree of life.
Introduction: The complexity of structures is being compared to distinguish the homology from analogy is known as molecular comparisons. The molecular evidence is used to determine the very early branching on the tree of life.
