I can also think of a reason why these regional variants come into existence, excluding the Grimm adapting in general. I believe the lore guide implies that the Grimm pools in the Land of Darkness aren't the only one's in the world. Which would make sense, because how would creatures like Beowolves cross continents?

So I'm thinking that Grimm pools can be found on each continent, but in hidden locations and that each pool spawns different Grimm depending on the surroundings of the region they're in. A Grimm pool in Solitas will spawn Grimm that are capable of withstanding cold, while one in Vacuo spawns Grimm that can handle the heat and sandstorms.
