When two populations of the same species of snake are isolated from one another for several generations and later come into secondary contact with the ability to interbreed successfully, you can conclude that they have not evolved significant reproductive barriers during the period of isolation. In the context of evolutionary biology, species are considered distinct when they cannot produce viable, fertile offspring through interbreeding. Since these snake populations can still interbreed, this suggests that they have retained enough genetic compatibility and have not yet diverged into separate species; they are still part of the same species.
