Dear Bill, I would like to comment on your statement "We are publishing our results in a refereed journal, so it will be a part of our scientific legacy". The journal FAMILIA published by the Ulster Historical Society is not a high impact journal like Science, Nature or PNAS, where rigorous standards of peer review are upheld. I may believe your RCC model and your assertions that you can get an age of a mutation from a mix of haplotypes, some of which have the mutation and some of which don't, when your results are reproduced and published in a high profile journal.

Can you say the same? Bye from Bill Howard
