Pupils will learn about random genetic mutation as a source of heritable variation, and that evolution occurs through the natural selection of genetic variants linked to advantageous phenotypes that are best suited to the environment.

Pupils learned that (phenotypic) variation between individuals of the same species means some individuals are better adapted to compete, which can lead to natural selection and cause the heritable characteristics of a species to change (evolve) over generations.
