One possible explanation for the increase in white-furred rats could be that they have a genetic advantage in their environment. White fur may provide better camouflage in their habitat, making them less visible to predators. As a result, white-furred rats may have higher survival rates and be more successful in reproducing.
Another explanation could be that there is a preference for white fur among potential mates. If white fur is perceived as a desirable trait in rat partners, white-furred rats may have more opportunities to reproduce and pass on their genes. Over time, this preference could lead to an increase in the population of white-furred rats compared to black-furred rats.

As a 7th grader, you may observe that the white-furred rats have adapted better to their environment compared to the black-furred rats. For example, white fur may provide better heat regulation in their habitat, allowing them to thrive and reproduce more successfully. Additionally, white fur may also help them blend in with their surroundings, making it easier for them to avoid predators and survive. These factors combined could explain why the white-furred rats are outnumbering the black-furred rats in the wild.
