I may have read it, but if so, it was about three years ago. I do remember
him writing about first-order kinetics.

[He refers to a logarithmic approach where transition of the base haplotypes
into mutated ones is described by first-order kinetics ln(B/A)=kt, which is
a Poisson distribution.]

The Poisson distribution is a distribution of frequencies. I may be missing
something, but what is it about ln(B/A) = kt that leads you to the
conclusion that it is a distribution? Can it be turned into a distribution
perhaps?

Have you read his other paper "DNA Genealogy, Mutation Rate, and Some
Historical Evidence Written in the Y-Chromosome: I. Basic Principles and the
Method'?

He refers to a logarithmic approach where transition of the base haplotypes

a Poisson distribution.
