Quizplus · Accepted Answer

The statements collectively describe a scenario where light-colored mice on both coasts have distinct genetic backgrounds (i), share a common ancestry (ii), and yet evolved their light coloration independently due to similar selective pressures in their respective environments (iii). This suggests convergent evolution, where similar traits evolve independently in different populations.
