Global warming has led to less snow cover in some areas. Snow cover provides insulation for some burrowing, hibernating animals. In a population of rodents, some animals have slightly thicker fur, and animals with this trait are more likely to survive the winters with low snow cover and thus produce offspring in the spring. There are different versions of the gene that codes for fur thickness, one of which codes for thicker fur and another that codes for thinner fur. In 1995, about 50 percent of the animals had thicker fur, and the other 50 percent had thinner fur. In the spring of 2012, after several years of low snow cover, 70 percent of the population had thicker fur, while only 30 percent had thinner fur. This change in the population is an example of
