When two populations spring off from one, when a population splits into two, by some kind of random accident, some kind of separation, a geographical separation, onto different islands, or separated on different sides of a river or a mountain range, or something like that. Then the ordinary variation that happens in every population, is no longer tied to each other. These two population...
