Unit Six: Evolution
Where does the great diversity of life on this planet come from? How do the living things today relate to the evidence we find of life from the past? Life is not static, it does not stay the same. Evolution provides an explanation of the processes that have shaped life over time. It is based on the central idea that all living things are related to each other through a common ancestor and there are fundamental rules which govern the changes observed in all species.
