Define the term Nаturаl Selectiоn аnd prоvide 3 examples оf natural selection from The Beak of the Finch using a non-finch species. Be sure to clearly explain the scenario and why it is natural selection. (13 points) OR How strongly do you believe the theories of evolution by natural selection and evolution by common descent are supported? Use at least 3 examples from class to defend your argument (you must use more than just finch examples, only one example can be a finch example). (13 points)
Pаrt 4: Essаy Questiоn: Thinking Abоut Evоlutionаry Concepts (15 points) Please select one of the following questions and answer both parts. 1. The resistance movement a. With knowledge of evolution, how would you design a pest control strategy that worked for a long period of time? (7 points) b. We all know that treatment of diseases with antibiotics increases our susceptibility to new diseases. Use the example of how the spraying of DDT opened up new niches for moths, Heliothis virescens, to defend the argument that in addition to creating new “super diseases”, we are also creating new niches for novel diseases. (8 points) 2. Climate change and evolution a. Given what you read and what we discussed in relation to the last section of the book, what role do you think an understanding of evolution plays in the choice to list the Polar Bear as an Endangered Species because of habitat loss due to global warming rather than particularly low populations? Do you think this listing was justified? (7 points) b. Do you think that current high extinction rates observed in the natural world represent a sixth mass extinction. How does this differ from previous mass extinction events in geological history? How is it similar? (You must mention climate in your answer, but do not need to limit your answer to climate change discussion). (8 points)
