BSCS Unit 4, Chapter 19 Changes in Species 1. Study the photo on p. 498 of Archaeopteryx. Go to http://www.ucmp.berkeley.edu/diapsids/birds/archaeo pteryx.html and read about this earliest example of a flying dinosaur. Give examples that it is a bird AND a reptile. Cite examples in today’s birds that might indicate their links to dinosaurs. 2. What are the evidences that evolution occurs and has occurred? 3. Define paleontology. How is it used in our study of biology? 4. Read Biological Challenge on p. 502. You will have an article to read about this in your assignments section. 5. What is extinction? What are the causative factors? Give examples. 6. Explain the concept of coevolution. Study Figure 19.6. Read the caption and explain how natural selection worked in these cases. 7. What does the statement “Nothing in biology makes sense except on the light of evolution” mean to you? 8. What are pseudogenes? 9. Study the diagram below and explain it. 10. What is the significance of a nearly university genetic code with respect to evolution? 11. Define speciation. 12. What are the causative factors of speciation? What are isolating mechanisms? 13. Explain adaptive radiation. 14. The diagram on the following pages are of the beaks of the finches on the Galapagos Islands. There were actually 13 examined by Darwin. Explain this as an example of adaptive radiation, how and why there are so many different types and where these different finches live. 15. What is evolutionary stasis? Give an example. 16. Read the Biological Challenge on p. 512 about mass extinctions. In the diagram below are the 5 major mass extinctions of Earth’s history. Study the diagram, then answer the question below it. What percentage of organisms were wiped out in the Ordivician period? In the Cretaceous? What major group was wiped out about 65 mya? 17. Read Focus On p. 513. How does the fossil record provide evidence of the rate of evolutionary change? What is the significance of “living fossils?” 18. Read Theory on p. 514. The two evolutionary patterns of evolution are gradualism and punctuated equilibrium. After you understand the mechanisms for each, give your reasons for choosing one pattern over another. 19. The following diagrams are representative of “vestigial structures.” After viewing them, how would you define this expression?
