Lesson details

Key learning points

  1. Darwin proposed the theory of evolution by natural selection to explain animals' adaptations.
  2. The theory is based on the idea that within a species, there are variations and competition.
  3. Within a habitat, some individuals will be better-adapted and others will be less-well-adapted.
  4. The better-adapted individuals are more likely to survive and reproduce, passing on these advantageous characteristics.
  5. Over a huge period of time, the advantageous characteristics become normal in the species (or can create a new species).

Common misconception

Pupils may believe that evolutionary changes happen rapidly.

Evolution is a process that occurs over huge periods of time.

Keywords

  • Variations - differences between individuals in a particular species

  • Natural selection - theory that organisms with characteristics beneficial for living in a particular environment will pass on these characteristics to offspring

  • Offspring - the young of an animal

  • Evolution - the way in which living things change and develop over millions of years

Show videos and pictures to support pupils' understanding of evolution by natural selection - particularly focusing on Darwin's finches if possible to support pupils' writing in subsequent lessons.
