Describe the difference between the evidence of evolution and the theory of evolution (natural selection). 3. Explain how fossils and biogeography (locations of living things in certain places) support the idea of evolution. 4.

Describe what “differential reproductive success” means. 9. Explain how variation is important to the process of natural selection. 10. Describe the evolution of the black and peppered moths in England and how this story supports the notion of natural selection. 11. Define the terms “gene pool” and “allelic frequency” 12.
