Simply because they are different species doesn't mean they can't breed. Even in our world, animals of different species that are closely related can breed (like lions and Tigers, or horses and donkeys).

As far as the moon idea above, the moon appears to be a barren wasteland that no species could live on for a long period of time. If they did, their technology would be at a level where they could transport people from the moon to the planet, but Jaune's great-great-grandfather used a very primitive weapon when compared to modern ones. It is more likely that they are just separate evolutionary lines with a possible common ancestor (or if the narration is to be believed, Faunus could just be born from Dust like humans are said to be).
