That's someone's statement, not an explanation. I'm looking for someone to
go through their argument or derivation.

If we use the "one SNP somewhere in the Y per father/son transmission"
approximation which has been often used, then any of us has had about 200
generations (6000 years) to produce private or family mutations or
interesting clade-dividing SNPs in our male ancestral line. I think this is
true for most any post-agriculture haplogroup which are roughly the same
ages. To find 2 such SNPs will require looking at 1 percent of the Y one
way or the other. That's a million nucleotide sites.

Since I want to look for the clade-dividing SNPs, that requires somewhat
more searching.

Maybe Thomas will go through his numbers. Ken
