Anyway, what fun! :smiley:

I just like your signature quote . Most people quote the simple minded like Einstein but Dr Seuss, I still study his work.

The math is misleading. It assumes zero interbreeding.

I think it is (genealogy) only possible really to make big assumptions like that for discussions sake. It’s just a way of looking at it. I have no kids, but my cousins have 5 between them. Down the line, if each of those kids has kids, it will skew the numbers considerably. So, I think that the further back you go, the more our amount of relatives varies. Interesting though.

But yes, the powers of two situation is pretty powerful, mathematically. It’s sort of fractal geometry. Or maybe it is fractal geometry.
