This introduction to the evolution of mammals considers Darwin's observations on mammals and how he noticed that species fell into natural groups. This free course, School activities: Evolutionary tree of mammals, looks at evidence from fossils and DNA to examine which mammals are most closely related to whales.
After studying this course, you should be able to:
- develop an appreciation of the huge variety of different mammals that exist on Earth today
- see how fossil evidence can help us to understand evolutionary history
- understand how the structure of DNA can help us to detect differences between different species
- apply the techniques of DNA analysis to work out which mammals are most closely related to each other
- appreciate the importance of bringing together evidence from different sources.

School activities: Evolutionary tree of mammals
This course provides an introduction to the evolution of mammals.
We will be considering Darwin's observations on a great many mammals, and how he noticed that species fell into natural groups. We take as an example the evolution of one particularly interesting mammal, the whale, and look at evidence both from fossils and from DNA to see which other mammals are most closely related to whales. We see how the evidence from these two very different sources points to the same relationship and that this therefore provides overwhelming evidence that the conclusions must be correct.
This OpenLearn course provides a sample of Level 1 study in.
