wariber [46]

Answer:

The process of natural selection is acting on <u>Field mouse individuals</u> where as evolution is occurring on <u>Field Mouse population. </u>

Explanation:

As the problem shows, the field mice are the ones that natural selection is acting on, but only the ligher shade ones. Because the lighter shade individuals are more likely to survive in the beach because they blend with the environment.

Evolution occurred on the field mouse population because if you read the script in the end, they were able to successfully reproduce. This means that they evolved in such a way that they were able to survive in their new environment. (most likely carrying on the trait of light-colored fur)

Natural selection acts on traits, phenotypic traits, favorable to the environment. Evolution occurred because of the natural selection, because the favored trait enabled the organism to adapt to the environment.
