Question
Chapter 26, Problem 5TYU
Summary Introduction
Introduction: Phylogeny is the study of evolutionary history among organisms. The phylogenetic tree can be constructed from DNA sequences or morphological study. The organism shares a very similar morphology, or DNA sequences are most likely to be the descendant from a common ancestor. The closely related organisms that are immediately descended from a common ancestor is called the sister group.
