19. the rocks at the bottom of a stream are either black or white. snails that live on these rocks are a range of color from solid black to gray to solid white. a local freshwater fish loves to munch on these snails, but it cannot see the solid black or solid white snails when the snails are on matching rocks. grey does not blend into either rock color and is much easier to see which trait is natural selection selecting for? how will the population change over time?
