Yes. Lakes and streams are good "islands" of water to observe the phenomenon. As the Galapagos and other islands are to land animals, isolated waters are to fishes.
Introducing guppies into isolated waters results in populations which develop coloring patterns which distinguish them from the bottom if aggressive predators are not present (helps finding mates), of camouflage them if predators are present.
The cichlids in Lake Victoria offer an excellent example of divergence.

You are at a crossroad. You can choose to learn and take the path of enlightenment, or continue on the path of ignorance. It's up to you.
