Voles of two different colors, brown and gray, live on the same island. Hawks find these voles to be their primary food source. The voles are distributed through grassy areas in the north of the island and across lava flows in the south part. Which of the following is predicted by natural selection? Hawks find the voles by movement so it won't matter. A vole population that starts as a random mixture will never adapt to the environment. Brown voles are good at hiding in the grass; gray voles are excellent at climbing over lava flows. Consequently, the vole distribution will reflect the ability of hawks to identify each of them in its natural environment. If they stay as a mixed population, they will remain mixed because the two varieties will not interbreed with each other. The hawk population will be skewed toward the north side of the island
