Thanks Ken for your reply.

Well if I know a number I could run that number for the likely number of
mutations yes? And which fast markers where most likely to be affected.
Somehow population projections are done so, computing in reverse (knowing
History ) one should be able to have a better est. then the future. If you
were going to point me to any of the 3 solutions you thought of I missed it.

I know of three simplified versions of what you seek. I am not sure they
will tell you what you want to know. Of course the contingencies you
mentioned only scratch the surface of the things that could happen and do
happen to influence the outcome of the descendant ydna population today.
