To Test the Hypothesis That Natural Selection by Predators Favors

question 16

Essay

To test the hypothesis that natural selection by predators favors a match between coat color in oldfield mice and the color of their environmental background, Hopi Hoekstra and colleagues made silicone models of mice that were colored either light or dark. These model mice were placed in beach environments that had either light or dark backgrounds. If the hypothesis is correct, what do you predict will happen to the different mice in each background?
