Chapter 30, Problem 9TYU
Summary Introduction
Concept introduction: Animal phylogeny is a rapidly changing field. Biologists mostly depend on the fossils to compare the similarities of body plan and the pattern of development to determine the evolutionary relationships among various animal groups. Throughout evolutionary history, there are various changes seen in body plans. These changes in the body plan provide clues to animal relationships.
