<h2>Answer to part 1.</h2><h3>Claim based on the evidence:</h3>
The population of pocket mice evolved due to natural selection.
Explanation:
Natural selection is the natural phenomenon where a group of species fittest to the environment survives and the other group which is not able to cope with change will die and go extinct.
Here the gray mice population increases a white mice population decreases. As the white mice were seen by eagles easily and caught by them while gray mice survived due to gray color as this color do not make them prominent to recognized by the eagle.
<h2>The answer to part 2.</h2><h3>Evidence:</h3>
The evidence for this claim is the observation of the size population of gray and white mice and their environment.
Explanation:
The number of white mice decreases from 4 to 1 in 2 months, while the number of gray mice increased relatively.
And the population habitat is also gray. It means it is easy for gray mice to hide them from eagle than white mice.
And their environment means gray land also helps in selection of gray mice to survive.
<h2>Answer to part 3.</h2><h3>Scientific reasoning:</h3>
The scientific reasoning is natural selection, the growth of group fittest to the environment.
Explanation:
The gray pocket mice are unable to prey due to escape from the eye of an eagle. And their population size increases as the competition for food and shelter reduces due to decrease in white mice.
This makes them high in population size than white mice in 2 months.
