Chapter 28, Problem 16RQ
Summary Introduction
To define: The terms Marsupialia, Monotremata, Eutheria, and Theria and to list the mammal group under these taxons.
Introduction: The living mammals are classified into two clades, namely, therians, and monotremes. The living mammals include 29 orders, that is, monotremes (one order), marsupials (seven orders), and placentals (21 orders).
