A hundred years ago, 20.4% of individuals in a population of bears was found to have a genotype that was linked to an ability to hibernate for longer periods of time during long, harsh winters. Now, the population found in the same place as that studied a hundred years ago has 6.7% of individuals with this genotype. Has this population evolved? Yes, it has evolved   There is insufficient information to decide between the two options   No, it has not evolved
