This online resource looks at an example of natural selection in humans.

The two linked resources concerning sickle-cell anaemia are suitable for use with Year 10 students.

• The short film, The making of the fittest: Natural selection in humans, which describes how Dr Allison discovered the link between sickle-cell disease and resistance to malaria, and that the protection against malaria by the sickle-cell mutation shows how evolution does not necessarily result in the best solution imaginable but proceeds by whatever means available.
• The activity 'Testing a hypothesis' is a worksheet designed to actively engage students as they watch the film.
