Chapter 30.3, Problem 2C
Summary Introduction
To explain: When most of the major groups of animals evolved according to the current hypothesis.
Concept introduction: Animal phylogeny is the 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. Explosion in biological terms refers to the increase in
