On this course we will be taken on an illuminating and enjoyable journey centred on a seemingly simple question - what is a mammal?

As mammals ourselves, we might think we know all about our own class of animals. But this course might lead us to some surprising discoveries. We will look at how mammals are defined, how they evolved and the similarities between different mammal species as well as their crucial differences. We will discover the evolution of milk, warm bloodedness and the burgeoning mammalian brain, and examine the emergence of sophisticated teeth, exquisite ears, and an elaborate reproductive biology, plus a host of other mammalian innovations. Entwined in all of this will be tales of zoological peculiarities and personal reflections on how being a mammal has shaped the tutor’s life. 

The course offered is aimed at complete beginners, and so no previous knowledge or experience of biology, zoology or any other science subject is necessary to join this class. The class aims to be an enlightening, fun and sometimes irreverent investigation into our own animal family.

Course Information

Course Programme

Week 1 – A brief history of life. 

A potted history of life on earth looking at the major transitions that occurred between life’s origins and the emergence of our first mammalian ancestors, then what’s happened since.

Week 2 – Mammalian Taxonomy and the Platypus

A history of attempts to classify mammals – starting in the 1750s with Carl Linnaeus and moving through to the present day, with a special discussion of how the discovery of the duck-billed platypus in 1799 threw taxonomy into chaos.

Week 2 – Reproduction - Mammal Style 

A survey of how mammals breed and reproduce, which highlights a number of mammals’ most defining characteristics.

Week 4 –Sex and genes: from Y chromosomes to the Placenta

This week we focus on genetics, examining how it explains the origins of the Y chromosome – and the genetic basis the mammalian sexes – plus how paternal and maternal genetics play a critical role in shaping the evolution of the placenta.

Week 5 – Linking the Generations – Milk and Other Parental Investments

Mammals are named for their having mammary glands – this week we explore the evolution of these structures and the remarkable baby food they make. Milk is a fundamental link between generations of mammals – and the bonds it created between mothers and offspring also fostered many other intergenerational exchanges. 

Week 6 – Mammals big brains and the sense that feed them.

The folded grey matter that coats a human brain is an emblem of intelligence – but human brains aren’t structurally that unique. That grey matter – the cerebral cortex is a mammalian invention; we’ll look at where it may have come from as well a looking at the sensory worlds of mammals.

Week 7 – Warm Blood

Although birds are warm blooded too, endothermy – to give warm-bloodedness its more accurate name – is fundamental to mammalian life. However, scientists still aren’t sure how and why endothermy evolved. This week we’ll look at the various theories.

Week 8 – What is a mammal? 

This week we’ll think big and ask what then is a mammal?  How do all the pieces we’ve discussed this term fit together?  Is it possible to successfully define a mammal without just saying “an animal with fur and warm blood that grows up drinking milk”?

Week 9 – What the future holds

Biologists agree that we are now living through a mass extinction event – our species, Homo sapiens, is killing other species at an alarming rate.  In this final session we will look at the data underpinning this claim and discuss our moral obligation to the natural world and what the future might hold for mammals and all other life forms.
