Yeah, me too. I appreciate the levity, but the larger point is important because it's typically ignored.
Those we know as "Native Americans" or "Australian Aboriginals" are the descendants of the survivors of early migrants. How many different groups migrated on how many different occasions is largely lost for want of a record. But given human nature, it's entirely possible the ancestors of those living now fought with and perhaps eliminated competing groups. That doesn't make them worse than anyone else, but neither is it consistent with the pose of virtuosity to which we are so often subjected.
