Where are the scientists exploring evolutionary processes? Explain the geologic and
Geographic environment.
2.
What animal is used to illustrate the evolutionary process?
3.
What is the problem introduced by geology on the animal?
4.
How is the new color introduced in the population?
5.
What is the goal of the lab work?
6.
Explain how a genetic mutation occurs.
7.
A mutation has the reputation of being a bad thing. Are all mutations bad? Explain.
8.
Explain how a mutation led to a rapid change in the population of this animal.

10. Explain adaptation in relation to the example in this video.
11. What proof do we have that the evolution of the animal in this video is
not just an isolated incident?
Part 2. Most rock pocket mouse populations have sandy-colored fur. This is consistent
with the light color of the desert rocks and sand on which they live. However,
dark-colored rock pocket mouse populations have been found living on black, basaltic
rock formations produced by recent geologic lava flows in the desert. What is the best
explanation for the difference in fur color?
Requirements:
● Construct a 2-3 paragraph essay addressing the question above.
● Include the following words or phrases in your short essay explaining how
each applies to the color variation seen in the rock pocket mouse:
1. mutation
2. survival of the fittest
3. natural selection, and
4. geology drives biology.
● Make sure to underline, bold or add color to these in your essay.
