Like move validation, evolutions are the earliest thing we wish to traverse when determining what encounters may have originated the current Pokémon. To determine the permitted species-form-levels a Pokémon could originate with, we must devolve a Pokémon by traveling down-generation to origin. Once we have an encounter, we can then evolve it to the current species, traversing upwards from origin to the current format.
