If their reproductive isolation was complete, then they will have already developed into two separate incompatible species.
If reproductive isolation subsequently is achieved, it will lead to a separate species.

This preference could result in reproductive isolation if two populations came into contact again.
Given sufficient time, these variations may lead to reproductive isolation.
Related to this is a new area of interest, in reproductive isolation.
But, scientists have long wondered, how quickly can reproductive isolation evolve?
