>>59063672Huh, never really thought about it, i think its implied that eevee evolves dependant on its enviorment and the evolution stones are like a shortcut to that effect.
And i think there are anime instances of a pokemon evolving without a stone.
So if experiance and leveling up simulates a pokemon evolving in order to deal with external stress. Stones sort of work like a concentrate in order to shock the system into acclimating when the enviorment is normal.
At least that fits for me. I dont think there is any official lore on where stones come from.
