Mammals come in a bewildering variety of shapes and sizes, and yet all species have some characteristics in common. These similarities justify the inclusion of all such diverse types within the single taxonomic group (or class) called the Mammalia. This free course, Introducing mammals, offers a starting point for the study of mammals. It will establish their rich diversity, while highlighting the common features that define the group.
