" Human history is replete with the fluid movement of people, and tribes and countries and cultures and empires are never, ever permanent. Over a long enough time-scale, not one of these descriptions of historical people holds steadfast, and only a thousand years ago your DNA began being threaded from millions from every culture, tribe, and country. If you want to spend your cash on someone in a white coat telling you that you’re from a tribe of wandering Germanic topless warriors, or descended from Vikings, Saracens, Saxons, or Drogo of Metz, or even the Great Emperor Charlemagne, help yourself. I, or hundreds of geneticists around the world, will shrug and do it for free: You are. And you don’t even need to spit in a tube—your majesty. "
