@penninx ” the total set of my ancestors in the year 1000 was percentage X. The descendants of one ancestor in the year 1000 are now a percentage Y of the population. X is large, Y is small.” – This is not quite correct, if I’m reading you right. Anyone around a thousand years ago in Europe, who left any descendant to the present day, is likely an ancestor to everyone in Europe (. Y=~100%). This also follows from the fact that your family tree branches very rapidly backward in time, so [as laid out by Chang and others].
The present: In Utah, the fabled remains of Mormon pioneers, whose 19th century expedition across the desert met with a murderous end, have been uncovered. In Washington, ., the official investigation of a international entrepreneur, an elder in the Mormon church, has sparked a political battle between the White House and a powerful United States senator. In Denmark, a Justice Department agent, missing in action, has fallen into the hands of a dangerous zealot – a man driven by divine visions to make a prophet’s words reality. And in a matter of a few short hours, Cotton Malone has gone from quietly selling books at his shop in Denmark to dodging bullets in a high-speed boat chase.
