Talk:Faunus (WoR episode)/@comment-10390252-20161128122223/@comment-26397825-20161128123930

Or it's like evolution in our world; Homosapiens and Neanderthals are actually two different species but they came from the same base genetic array and were compatible. It's just that Homosapiens bred the Neanderthals out, and the Neanderthals brais weren't as developed as Homosapiens which meant they died more stupid deaths.

Same thing could have happened here; there's something in the Faunus dna which does throwbacks to random animals that developed off different branches as the world evolved, and it's a dominant and useful trait so it was never bred out of them.

Differing ecosystems (so, say, humans developed in a more naturally portected area whereas faunus developed in an area where the extra hearing of a wolf would benefit them more) can result in different species as well, even if they come from the same base dna. A bit like lions and tigers, in that aspect; both big cats but different species, even though they developed from the same big cat way back when.
