To determine which scenario is most likely, we need to understand the relationship between temperature and fur color in rabbits. In this case, an increase in average temperature is causing a shorter winter. Let's think about how this might affect the survival and reproduction of white-furred and brown-furred rabbits.
White-furred rabbits have an advantage in snowy environments because their fur color provides camouflage, making it harder for predators to spot them. On the other hand, brown-furred rabbits are more visible in a snowy background. With a shorter winter and less snow cover, the advantage of white fur for camouflage may decrease.
Given this information, the most likely scenario would be that the proportion of white-furred rabbits in the population declines. As the advantage of white fur diminishes in a shorter winter, brown-furred rabbits may have a higher chance of survival and reproduction. Over time, this could lead to an increase in the proportion of brown-furred rabbits in the population.
Therefore, the correct answer is: The proportion of white-furred rabbits in the population declines.
