A population of snakes includes solid-colored snakes and banded (striped) snakes. On the mainland, the snakes are mostly solid. On a nearby island, the snakes are mostly banded. You hypothesize that the reason for this observation is that the environments on the mainland and island are different, and banded snakes are favored in the island environment. Which of the answer choices are possible alternative hypotheses to explain why the snakes on the island are mostly banded? Select all that apply.
