As in the previous question, suppose there is a population of 100 rabbits that have different fur patterns. In this population several generations ago, there were 60 FF rabbits, 20 Ff rabbits, and 20 ff rabbits. Over time, the population changed, and now there are 40 FF rabbits, 40 Ff rabbits, and 20 ff rabbits. Has microevolution occurred? Why or why not?
