Chapter 23.3, Problem 8LO
Summary Introduction
To describe: The way in which analyses of molecular homologies contribute to the science of systematics.
Introduction: The branch of science that deals with the scientific study of diversity and evolutionary relationships of organisms is known as systematic. Historically, people considered that higher taxonomic groups contain species with certain defining features that they all share.
