I think I'm still missing the legtimacy of that sea salt theory. Slave trade Africans didn't spend entire generations on ships, to my knowledge. The idea that the only ones who had the genetics to survive such conditions can be relegated to one race, rather then the circumstances is a little suspect and fixated on race in it's own way. In order to use this theory to prove race doesn't exist, you still have to seperate the Black Africans somehow.... if not by race, then by some other reason. What reason? Time at sea exposed to salt air, with little nourishment, and brutal conditions? That aspect of the story isn't unique at all to history.

Wouldn't this mean the Pilgrims of Plymouth Rock would have this exact gene? Who else traveled by boat? Maybe it's not the salt air after all...maybe it's a gene procurred through survivors of extreme conditions when shackles are involved? Ahh! Don't make me get out my Viking novels!
