In this unit we look at the how life on Earth has developed.
The unit is split into 3 parts…
  • In unit B6.1 we look how the theory of evolution was developed.
  • In unit B6.2 we look at how we can classify the millions of different species that live on Earth.
  • In unit B6.3 we look at how humans threaten biodiversity and how we can make the resources on Earth more sustainable.
