User blog comment:CreatorTheta/Human Evolution Theory in RWBY/@comment-3146930-20140623192955

The Grimm seem to be around before humans, as the narration states that man was born into an unforgiving world or something like that.

As far as everything else goes, the planet RWBY takes place on is riddled with things that wouldn't even appear on our Periodic Table of Elements. According to the narrator for the first episode, humans (and possible Faunus) were born from Dust, not the regular elemental Dust we have seen in the show; Dust was named after Dust. Anyway, Dust could explain all the abilities in show show because even if the humans look like humans, they are made from a very different primordial soup.

This is going to sound very creationist, but humans on this planet may have simply been created this way by a higher power. Now I know this may sound crazy, but it is entirely possible that the planet itself is alive and has its own Aura. Living planets are something that appear in almost all forms of media from Sci-fi movies to comic books (one such planet is a Green Lantern; I think his name is Mogo). The planet may have created humans as a way to defend itself from the Grimm.

To try and support this, I made a forum topic awhile back explaining that Pyrrha called the Grimm the manifestation of anonymity, meaning the physical form of being faceless and identical. They destroy anything that has any form of individuality, so the planet may have made a race of beings that were completely different from each other as a way to balance the equation or maybe defend the creatures that existed before humans. This would also explain the reason all Faunus have different animal traits; they could have been the planet's attempt to make animals into humans or possibly the planet trying to give humans additional gifts.

I'm not saying in the least that there is a giant brain in the center of the planet and that it could just kill anything it wanted. However it is possible that the planet is alive and its Semblance is making life. It creates with will, but not with thought.
