Li Please read over and answer these prompts in this discussion forum. You will not be able to view the responses of others until you have completed your post. Once you are done I encourage you to review and reflect upon the responses of others as well. Please refer to the Topic Review Rubric Use the lectures in the videos and your textbook reading to help you answer these questions in the discussion forum provided 1. Explain what the biological species concept is. Why is this species concept inapplicable to asexually reproducing organisms? 2. In the Speciation and Extinction podcast, Mr. Andersen discusses speciation of two varieties of stickleback fish. Describe the environmental pressure that drove the process of speciation in these fish and the role that natural selection played in this process. 3. Explain why island systems are ideal locations for the process of adaptive radiation to take place. Describe other situations that could create ideal conditions for adaptive radiation to occur 4. Explain what makes reproductive isolation such an important component of the species concepts discussed in the chapter 5. Draw an example of each of the following examples of reproductive isolation. Your drawing should explain how each type of isolation leads to the formation of a new species without using any words. 1. Geographic isolation 2. Behavioral isolation 3. Temporal isolation 4, Mechanical isolation barrier and the evolution of a postzygotic barrier the males of their species based on an attractive appearance or behavior. Explain how sexual 6. Why do reproductive barriers evolve? Describe an example of the evolution of a prezygotic 7. Recall that sexual selection is the process by which females of a species seeking a mate select selection could lead to reproductive isolation. 8. Distinguish between allopatric and sympatric speciation. Give two examples of each type of speciation. 9. Discuss the differences between the two schools of thought regarding the tempo of evolutionary change: punctuated equilibrium versus gradualism.
