The term mammal encompasses a huge variety of animals, including humans. But what makes a mammal a mammal? This unit explores some of the features, such as reproduction, lactation and thermoregulation methods, that mammals have in common. It is the first in a series of 10 ‘Studying mammals’ units.
By the end of this unit 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 amongst species;
- distinguish between behavioural and physiological temperature regulation;
- describe, with examples, the insulating properties of hair;
- distinguish between appropriate and inappropriate uses of the terms ‘primitive’ and ‘successful’.

Studying mammals: A winning design
Mammals come in a bewildering variety of shapes and sizes and yet all of the 4700 or so species have some characteristics in common. Indeed, it's the existence of these common features that justifies the inclusion of all such diverse types within the single taxonomic group (or class) called the Mammalia.
This is the first in a series of units about studying mammals. To get the most from these units, you will need access to a copy of The Life of Mammals (2002) by David Attenborough, BBC Books (ISBN 0563534230), and The Life of Mammals (2002) on DVD, which contains the associated series of ten BBC TV programmes. You should begin each unit by watching the relevant TV programme on the DVD and reading the corresponding chapter in The Life of Mammals. You will be asked to rewatch specific sequences from the programme as you work through the unit.
This unit is from our archive and is an adapted extract from Studying mammals (S182) which is no longer taught by The Open University. If you want to study formally with us, you may wish to explore other courses we offer in.
