What happened to the Gauls?

[Philippus Flavius Homovallumus]

Well, that's the point. It's hard to pin-point these markers without really rare, isolated groups of people. But now we know what that Icelandic marker means so we can trace the migrations of those people. And trace their impact on other peoples. That small group of people had a huge impact because they were the greatest explorers of their age. That's fascinating.

Just think about it, The history of all the people in the world is in our bloodlines if we can just isolate the genes.

Don't forget Icelandic people are just isolated Norse, viewed from that point of view the fact that a Norse marker turns up all over isn't at all surprising.
