Part A Write a paragraph (5-6 sentences) explaining how natural selection has acted on coat coloration of the populations of rock pocket mice living on lava flows in New Mexico’s Valley of Fire. Be sure that you clearly explain which of the processes and events that you describe are random and which are not.
Part B The hair length of Canadians varies considerably. Some people (mostly men) shave their heads, while others have never cut their hair. Is natural selection acting to bring about evolutionary change in hair length in the Canadian populations? In your answer, address the two conditions that are necessary and sufficient for natural selection to bring about evolutionary change in a population and explain whether these conditions are met for this trait. Write a paragraph (8 sentences minimum)
