The mice living in an area changed from having brightly colored fur to having darkly colored fur. How did natural selection most likely result in this evolutionary change?

Dark mice can camouflage with their surroundings better than bright colored mice, so the last ones did not survive since they are not suitable for that environment.

Explanation:

Natural selection is the process that gives new generations of an organism with changes in their genes. The modification in the composition of genes or their genotype makes suitable offerings that will continue the species existence. In this case, the change was the color of the mice fur that made it suitable for its surroundings and increased the species continuity and survival.
