Evolution
What this topic asks you to be able to do
- outline the theory of evolution, in which changes to gene pools from one generation to the next lead, over time, to new species forming from species that already exist
- discuss the ways in which evolutionary relationships between species can be revealed by DNA sequence data
- explain how genetic isolation can lead to speciation, either through geographical separation (allopatric speciation) or through separation by ecology and behaviour (sympatric speciation)
