Questions:
1. What is fossil evidence?
2. Why do you think fossil evidence is considered the weakest link of
proving evolutionary relationships (as compared to another method
such as amino acid analysis)?
3. What is a homologous structure? What is an example of this?
4. Why are homologous structures considered divergent evolution?
5. What is an analogous structure? What is an example of this?
6. Why are analogous structures considered convergent evolution?
7. What are vestigial organs? What is the most obvious vestigial organ in
humans?
8. What does the part of the prezi that says “homology informs
phylogeny” mean?
9. What is comparative embryology?
10. Why would DNA and amino acid sequencing be considered a very
strong evidence of evolution between organisms?
11. What is biogeography? Give an example.
12. Explain observed evolution.
13. What happened with peppered moths in England during the Industrial
Revolution?
