User blog comment:CreatorTheta/Human Evolution Theory in RWBY/@comment-7622429-20140623153550

OR maybe they exist in a fictional magitech world that only bears slight resemblances to the real world, but greatly exaggerates certain aspects or underplays others to accomodate the thematic and presentative qualities of the world and those that inhabit it. In other worlds, the creators can make it do whatevr the hell they want to. Humans came from dust? Sure thing. The creatures of Grimm? Maybe they aren't the Grimm, but come from the Grimm. Whatever that might be. And the Faunus? Maybe not even a different species from Humans. Until we get confirmation of Human/Faunus hybrids, that is.
