My ancestors came from Planet Earth- though there are a couple in the family tree we are wondering about. Mostly from what you know as "Europe"- going back a couple hundred years or so. It gets hard to trace back much before then. Mostly from the "human" species.
American mixed blood like just about everyone else. My ancestors come from the Czech Republic, France, England, Cherokee Nation, Choctaw Nation, and I'm sure there is even more mixed in.
There's no real danger...the orthodontist filed down my canine teeth prior to removing my braces (without permission, of course--bastard.) So you folks can rest easy...
