Genetic divergence must occur before the snails can be described as two separate species. This means that over time, the snails in the two populations must accumulate enough genetic differences that prevent or reduce interbreeding if the populations were to come into contact. Without genetic divergence, the snails would still be considered one species regardless of their physical location.
