Color Variation over Time in Rock Pocket Mouse Populations
[Mechanisms of evolution: Grades 9-12] Evolution results from selection acting upon genetic variation within a population. (LS4.B) [Mechanisms of evolution: Grades 9-12] There is variation within a population. (LS3.B) [Mechanisms of evolution: Grades 9-12] Natural selection acts on the variation that exists in a population. (LS4.B, LS4.C)

COLOR VARIATION OVER TIME IN ROCK POCKET MOUSE POPULATIONS 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. And at just 15 grams, this tiny mouse weighs about as much as a handful of paper clips.

1. The four illustrations provided by your teacher represent snapshots of rock pocket mouse populations. Each illustration shows the color variation at two different locations, A and B, at a particular moment in time. The illustrations may be out of order. Count the number of light-colored and dark-colored mice present at each location at each.

Mouse Color Variation Over Time in Rock Pocket Mouse Populations
Dr. Michael Nachman, working in the field and lab, 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. KEY CONCEPTS A mutation is a random change to an organism's DNA sequence.

Rock pocket mice, Chaeotdipus intermedius, are an ideal system in which to study intraspecific phenotypic divergence because of the extensive color variation observed within this species..

Description This film describes natural selection and adaptation in populations of rock pocket mice living in the American Southwest. Mice living on light-colored sand tend to have light-colored coats, while mice living on patches of dark-colored rock have mostly dark-colored coats.
Color Variation in Rock Pocket Mice Over Time (Day 1) Quizizz
11 Members Description This animation shows why different fur colors can be advantageous to mice in different environments. Rock pocket mice can have either light-colored or dark-colored fur. As shown in the animation, mice that blend in with their surroundings are harder for owls and other predators to see.

And at just about 15 grams, this tiny mouse weighs about as much as a handful of paper clips. Rock pocket mice, however, have had an enormous impact on.

This activity explores physical and genetic evolutionary changes in rock pocket mouse populations, as discussed in the short film The Making of the Fittest: Natural Selection and Adaptation. This film uses the rock pocket mouse as a living example of Darwin's process of natural selection.
