It's been stated that the Grimm came from the darkness, but exactly HOW do they come into existence?

Are they animals tainted by a corrupted version of Dust? A secret, yet far more sinister future for Hunters and Huntresses after longterm exposure to the smoke Grimm corpses emit after dying? or are the Grimm themselves ancient people or Faunus  who performed a forbidden spell, driven by rage and vengeance to destroy their enemies, only to become empty, undead husks that destroy all in sight instead?

What do you think?
