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.
Course learning outcomes
After studying this course, you should be able to:
explain the distinctive biological features of monotremes
distinguish contrasting modes of reproduction in monotremes, marsupials and placental mammals
describe the cellular basis of lactation and explain the benefits of an early diet of milk
explain the significance of mammalian metabolic rate
explain how and why the thermogenic response differs among species.
Very informative and interesting, but as mentioned in another review, some of the video links are of no use; one of the National Geographic links on the echidna and one of the BBC links on kangaroo reproduction, which is frustrating as both are key to the activities.
