Part A
Write a paragraph 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 how natural selection differs in the populations of mice living on the lava flows and the populations of mice living in the nearby desert.

Is natural selection acting to bring about evolutionary change in this trait in the Canadian population? 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.
