![]() ![]() For rock pocket mice, which of the following contributes to selective pressure favoring dark-colored fur? Write "yes" or "no" next to each of the four possible responses. Which of the following could explain this observation? The volcanic rock caused the same mutation in each rock pocket mouse population, resulting in dark coloration. The sequence you get is identical to that of the same gene in another rock pocket mouse population with dark-colored fur that lives on a different patch of volcanic rock. You take a DNA sample from a member of this new population and determine the DNA sequence of a gene known to play a role in fur color. This assignment requires students to take the roles of scientists and use traps at two simulated locations to determine what is happening to the populations of dark coated and light coated mice. Suppose you are studying a recently discovered population of rock pocket mice with dark-colored fur that lives on volcanic rock. The Rock Pocket Mice of southwestern United States have demonstrated a very clear and interpretable case for microevolution. Natural selection chooses the best of the best to survive, so if you can reproduce and survive. Mutation just happens when our genes get randomly mixed up. of cards in the right order one demonstrating the evolution of Rock Pocket Mice. Students analyze data from images of rock pocket mouse populations in different settings and over time. (circle correct answer for each) Why There will be more black mice and less brown mice than before in the Rock Pocket Mouse population. Carroll states that "while mutation is random, natural selection is not." In your own words, explain how this is possible. This Natural Selection Review activity strongly reinforces the key. The selection process was mutation it was chosen randomly and it didn't matter which animal was picked. They can survive longer and reproduce more. Once the mice started evolving their level of fitness increased majorly. Evolution Revised October 2018 of 3 Color Variation Over Time in Rock Pocket Mouse Populations Activity Student Handout INTRODUCTION A typical rock pocket mouse is about 170 millimeters long from its nose to the end of its tail, shorter than an average pencil. Include the following key terms: "fitness" (or "fit"), "survival" (or "survive"), "selection" (or "selective"), and "evolution" (or "evolve"). In three to five sentences, explain how this trait increased in frequency in the population. As you saw in the film, rock pocket mice evolved to have dark-colored fur in certain habitats. It makes a species mutate and once that one animal does its offspring will also mutate and so will its offspring. Explain how the environment plays a role in changing the frequency of a mutant allele in a population. ![]()
