Natural Selection in Mouse Population

Evolution is a fundamental concept in biology that explains how populations of organisms change over time due to various processes. One of the key mechanisms driving evolution is natural selection, which favors traits that enhance an organism's chances of survival and reproduction in a given environment.

Imagine a population of brown mice living in a desert environment with sandy soil. These mice are better camouflaged against the sandy background compared to their white counterparts. As a result, brown mice are less likely to be seen and preyed upon by predators. Over time, the frequency of brown mice in the population increases due to the survival advantage provided by their coloration.

Based on this scenario, which of the following statements best describes the role of natural selection in the evolution of the mouse population?
