Populations of the same species that live on the white beaches of Florida and Alabama have light fur. Describe the evidence you would need to collect to support the claim that the differences in color in these populations are due to natural selection.
The dark colour mice lives in the dark soil of southeastern United States in large number as compared to other colour mice because this colour helps them to hide themselves from their predators in that dark soil while on the other hand, on light beaches of Florida light colour mice lives because this light colour also helps these mice in hiding from their enemy animals which is a true example of natural selection because dark colour mice can't survive in light colour beaches dude easily seen by their enemies and reduces its population by eating them.
