Biology Unit 07: Evolution Review
- 1. What do homologous structures tell us about two species? Compare homologous structures to analogous structures. What types of homologous structures provide evidence of evolution?
- 2. Practice using cladograms.
- 3. How are the organisms on Galapagos related to the organisms on the nearest mainland? What makes this an ideal case study for adaptive radiation?
- 4. What is embryology and what evidence does it contribute to the Theory of Evolution?
- 5. Describe the 3 types of selection. Provide examples of each.
- 6. There are sudden changes in the fossil records where species of organisms appear or disappear. What causes these sudden changes?
- 7. Explain the following: "Individuals do not evolve, populations do."
- 8. Compare gradualism and punctuated equilibrium.
- 9. What is natural selection? Compare natural selection with artificial selection. (What creates the selective pressure?)
- 10. Why is it necessary for us to continuously create new antibiotics and pesticides?
- 11. "The currency of evolution is babies." This is called reproductive success. Why is reproductive success important to evolution?
- 12. What is an adaptation. What does it have to do with natural selection.
- 13.How does over production aid an individual's reproductive success? How does it compare to organisms that have few offspring?
- 14.What is a codon? What kind of organism does the mRNA condon chart show the code for? How is this evidence of evolution from a common ancestor?
