- Adaptation
- Explaining development of different species
- Mention isolation/ separation/ splitting
- By geographical barrier.
- Different alleles in the species that were separated.
- Different conditions: climate; predators; food
- Therefore natural selection occurred.
- Mention isolation/ separation/ splitting
- Why scientists are uncertain about how life started on earth
- There is a lack of evidence
- Because early organisms had soft bodies therefore were decomposed quite quickly.
- There is a lack of evidence
- Explaining development of different species
- How Fossils provide evidence of evolution

- There is a lack of evidence
- Explaining development of different species
- 1. Fossils are remains of organisms that lived a long time ago.
- 2. Fossils show the changes over time.
- 3. Fossils have similar features to modern day animals
- Adaptation
- So the DIFFERENCE meant that the species were unable to interbreed.
