Re-reading the OTU timeline, it suddenly occured to that the Ancients visited Earth at a time when humans, as we know them, didn´t exist yet.
What I mean is, 300,000 years ago, homo sapiens sapiens - modern man - had not evolved from its ancestors. FWIW the stone-age tribes as we "know" them - the folks who created the cave paintings - appeared more or less 40,000 year ago. I´m not even sure if, 300,000 years ago, the famous Neanderthal man already existed.
Therefore, I´m not quite sure if it is realistic - as far as realism goes in a science fiction RPG - to portray all the minor branches of humanity as variations of homo sapiens sapiens. We evolved into HSS from what was around 300,000 years ago; however I don´t think it is all that likely that several dozen other populations of the same proto-humans in different environments did the same - and evolved close enough to be able to interbreed.
The stone age HSS (the Cro Magnon man) and the Neanderthal man co-evolved in the same environment, having "split" much more recently, but they still were just barely interfertile - and from what I´ve read about fossil discoveries, the result was a kind of "neither here nor there" half-breed, though apparently able to survive, and to procreate.
To sum it up, I think realistically we ought to see much more variety among humanity, even among those that were not "modified" visibly like Luriani and Sydites.
