If by the Poisson distribution, you mean the ln(257/89)/.022, then you've
misunderstood. It has nothing to do with Poisson. As I recall, it is simply
a check on the linear estimation by comparing it with an estimate using
proportion on modal. If the two answers come out around the same, he takes
it as a good sign that the mutations in the population haven't resulted in
some strange distribution.

If you are interested, I can explain what a Poisson distribution is.

number of generation.

Has this approach been applied for the populous surname projects -
MacLoughlin, O'Docherty etc. ?

Anotole did present a method to confirm whether a cluster shared a genuine
common ancestor but no - it hasn't been tried by one anyone on any results
from the M222 project. One of us has to learn how to do it first.
