British land snails are an example of disruptive selection. In the grassy fields, the light-banded snails escape bird predators. In the darker forest, the dark snails survive and the light-banded snails are eaten. The different colored snails have the opportunity to interact and breed across the British landscape. Why doesn't this "disruptive selection" eventually lead to two separate species?
A. The color forms are probably not genetically determined.
B. There is no reproductive isolation to prevent gene flow.
C. They are already two separate species, and the intermediate forms are hybrids.
D. This will result in the formation of two species if given a long enough time.
