Textbook Question
Chapter 19, Problem 3AC
Consider the following list of groups: (1) protists, (2) fungi, (3) seedless plants (ferns, mosses, and liverworts), (4) prokaryotes (bacteria and archaea), and (5) animals. Using Figures 19-6, 19-7, 22-4, 23-5, and 24-1 for reference, identify the monophyletic groups on the list.
