EX. Pokémon evolution is not your standard biological evolution. It is a hyper evolution, more akin to a metamorphosis, like a caterpillar into a cocoon into a butterfly. These transformations are triggered by anything from reaching a certain point in their training, to the use of certain stones and items, to the location that they train in.
No pokémon better shows off the latter kinds of evolution, stone related and location related, than the Evolution Pokémon, Evee.
