Dear Ken,

I have heard these words many times from those who did not bother to
calculate margins of error themselves, and, more than that, they had no idea
how to calculate margins of error. However, they were quick with their
"opinion". As always.

In that regard, it is strange to hear those words from you. You know how to
calculate margins of error. Why did not you do it, before expressing your
opinion? In my book of science it is a no-no.

I took 284 of 25-marker haplotypes, verified that they are derived from one
(technically) common ancestor, and found that they contained 1853 mutations
from the base (ancestral) haplotype. Your take?

Best regards,

Anatole Klyosov
