Step-by-step explanation:
In this case, the rabbits with white fur will have an advantage in the snowy environment as they will be better camouflaged and harder to see by predators. On the other hand, the brown-furred rabbits will be more easily seen against the white background, making them more vulnerable to predation.
Over time, this could lead to a shift in the color distribution of the rabbit population towards more individuals with white fur, as those individuals will have a higher chance of survival and reproduction in the new snowy environment. This change in the population's characteristics over time is an example of natural selection.
Therefore, the most likely occurrence in this scenario is that the rabbit population will gradually shift towards having more individuals with white fur.
