Thanks, Laura. I'd be surprised if noone ever said anything on the source,
but the article itself said absolutely nothing. It didn't even say if
they tested just one person or multiple people, though it is hard to see how
they could have tested multiple people and come up with an unusual subclade.

If I'd been them, I'd have tested more than one person just to make sure
something wasn't goofy with the genetic sequence of the person I happened to
choose.

I think it was in the early days of computers or something.

Yours,
