I'm not sure if I understand the question here. As written, the rules pretty much cover the various supernatural creatures as individual entities rather than sub-species of humanity. As WillH says, between Aspects and Creature Features there's very little that can't be modled.
If the question is more generally can the Fate system handle different character races I'd point you in the direction of Legends of Anglerre - which is a Fantasy version of the system and has other possible character races including Elves, Dwarves, Halflings, Centaurs, Dragons and Fauns. As well as a section on creating your own races. Mainly that's done by aspects and powers that members of that race may take (they don't have to), and several stunts that are only available to that race. I don't think any of the racial build pieces are compulsory, you just don't get the benifit of them if you haven't bought them.
