It concerns me that a single individual's chromosome can bump up the common ancestry age estimate from 170,000 to 340,000 – doubling it. That indicates that this estimate is incredibly sensitive to outliers. How can we know that finding another person with interesting ancestry isn't going to bump up the estimate by another factor of two? Also: regarding "The Ancestor's Tale" – this is probably the best non-fiction book I've ever read. If this kind of thing interests you at all, do yourself a favor and read it.
