Human: Can produce fertile offspring with H. Sapiens from Terra.
   Examples: Vilani, Zhodani, Solomani, Sword Worlders, etc.

   Comment: Generally, if you put a Human into the same sort of clothes you
     wear, you'd not necessarily spot them as "not from here" just by
     looking at them walking down the street. for example, a Zhodani might
     just be a somewhat tall Joe (as opposed to your average Joe); a Vilani
     might not be given a second look as a Caribbean Islander, a Sword
     Worlder might just be your average Nordic type, etc.

As a side note, though they would be homo sapiens, the split between Zhodani, Solomani and Vilani occured something like 400000 years ago, I think that's a pretty long period of time for them to be still mistaken for contemporary Solomani.
