They are an easily understood example of population genetics. (LS3.B) Mechanisms of evolution: Grades 9-12 Natural selection acts on the variation that exists in a population. (LS4.B) Mechanisms of evolution: Grades 9-12 There is variation within a population.

Rock Pocket Mouse Evolution Rock Pocket Mice Rock Pocket Mice inhabit the Sonoran desert of the Southwestern United States. Mechanisms of evolution: Grades 9-12 Evolution results from selection acting upon genetic variation within a population. Not all downloadable documents for the resource may be available in this format. The “Resource Google Folder” link directs to a Google Drive folder of resource documents in the Google Docs format. Remember that fitness is defined by an organism’s ability to survive and produce offspring in its environment. Explain why a rock pocket mouse’s color influences its overall fitness. They then compare amino acid sequences to identify variations associated with different coat colors. Color Variation Over Time in Rock Pocket Mouse Populations Evolution Revised October 2018 of 5 Activity Educator Materials 7. They then use a genetic code chart, to determine the amino acids encoded by a sequence of the Mc1r gene in different mouse populations. The activity begins with students reading a magazine article and watching the film. Students analyze genetic sequence data and draw conclusions about the evolution of coat-color phenotypes in the rock pocket mouse. This activity supports concepts covered in the film Natural Selection and Adaptation.
