Although the fishes can now interact with each other but they can no longer mate together due to the phenomenon of Geographical isolation.
In evolution, what does geographic isolation mean?
In the study of evolution, geographic isolation is referred to as allopatry. Geographic isolation between a portion of a species' population and the rest can cause that portion to eventually develop traits that are distinct from those of the parent population (due to natural selection).
It is well recognized that geographic isolation contributes to divergent evolution, producing distinctive phenotypes. It is crucial to allopatric speciation. Populations can evolve separately and eventually give rise to new species if geographic boundaries prevent gene flow for a long enough period of time.
The Galápagos finch is an illustration of speciation. The Galápagos archipelago, a collection of islands in the Pacific Ocean off the coast of South America, is home to many species of these birds. The ocean keeps the finches apart from one another.
