Dear All,
I agree with Anatole that this is a complicated issue. Back in 2009 I estimated the I calculated the A/B split at 147,246 years using 10 slow mutating markers. See The question we would like to know the answer to is where Y Adam was living at the time of the A/B split. I don't think we can readily answer that question at this time. I think that evidence now would suggest that he was likely living in Africa or somewhere in the Middle East. I suspect that he wasn't living in Central Asia or Eastern Asia. I agree with Ted that we should encourage testing of more people from Haplogroup A. It will be very interesting to follow this topic as more data comes in.

Dear Ted,

May I remain you (and others) that "Out of Africa" concept is a HYPOTHESIS, not a proven fact. It is a complex problem, and with our progress in collecting and analyzing data it becomes more and more complex. To trivialize it as it is done in the quotation above provided a disservice to science and to lay people who want to know the state of the problem, not just slogans.

When you move to the question WHEN they leave (without knowing if they leave from Africa and not that they came to Africa, which is equally possible), you should ask yourself - can it be 60,000 ybp? 70,000 ybp? - as the "Out of Africa" concept tells us. I have news for you: it simply could not be. I suspect that all of you who operate with slogans, have never looked at haplotypes of the Africans and non-Africans. The distance between them is astronomical. As I have told here before, the distance between haplogroups A and B is at least 120,000 years. Nobody here was able to comment on this result, except vague "it cannot be calculated".
