The thick beak birds are able to eat an indigenous nut that has a thick shell. The thin beak birds are not able to eat this nut.

What is true of these two species? A) Both species will continue to occupy the same exact niche. B) The two species can have viable offspring together. C) The two species cannot have viable offspring together. Eliminate D) The two species will be one species again in the future.
