I always wondered how the regional professors end up having 3 starters of grass, fire, and water respectively. They're obviously not found in the wild (excluding the anime), so where could they possibly receive them. I kind of thought that they're an in-dangered species, and that humans take good care of them, and maybe there's an organization that prevents pokemon species from extinction, and the few that they have breed, and they send them to a regional professor. I'm just taking a wild guess here. Anyone have a good theory?
