![]() ![]() Did natural selection produce the same result under the same conditions elsewhere? and 18. The volcanic rock caused the same mutation in each rock pocket mouse population. The making of the fittest: Natural selection and adaptation Video clip. How quickly can natural selection work 'The Making of the Fittest: Natural Selection and Adaptation' tells the story of a living example of Darwin's process. If they have a 10% survival advantage over lighter mice, the mutation would take about years to spread throughout the population. The mice in the two populations evolved from the same ancestral population. ![]() If individuals have a 1% survival advantage over lighter mice, then this mutation would take about _years to spread throughout the population. The black mice arose through a in a gene called with it have an on the dark lava rock.Ħ. What selective force drove this change in color (light to dark) over time? Individuals 15. Where are the lighter mice generally found? 14. Where are the dark mice generally found? 13. Forest Service Species of Special Concern California Department of. the information from the video to explain the evolutionary significance of MC1R. It sets up the next activity, a simulation that explores how this pattern might come to be over many generations. PART A: NATURAL SELECTION AND EVOLUTION OF ROCK POCKET MOUSE POPULATIONS. Rock pocket mice in this area come in two different colors: 12. This video introduces students to the rock pocket mouse, whose coat color tends to match its habitat. The darker color of the ground in this region comes from years ago. This activity supports concepts covered in the film Natural Selection and Adaptation. Introduction: The tiny rock pocket mouse weighs. The light color of the ground in this region comes from Amala A South 10. Natural Selection and Evolution of Rock Pocket Mouse Populations. Lets revisit and build on the Rock Pocket Mice Model of Genetics from Lesson 1. It highlights the research of Michael Nachman, who has quantified predation on rock pocket mice and identified adaptive changes in coat-color genes that allow the mice to travel under the radar of hungry predators.to learn about the people who contributed to this theory. Students view a brief video that presents research findings concerning the roles of mutation and natural selection in the evolution of fur color in rock pocket. This film uses the rock pocket mouse as a living example of Darwin's process of natural selection. Transcribed image text: Part II: Rock Pocket Mouse To complete part two, you'll watch Rock Pocket Mouse Video (opens in a new window) and answer the questions below. ![]()
