Perhaps results from TMRCA formula based on STR mutations are more complex
than they can superficially appear. I think they are evidence, just like
any other evidence. I think as a "ball park reality check" they are very
useful, and it is a pity to dismiss any evidence. It would be better to
spend time to ensure a good understanding significance of confidence
intervals, than to avoid using the evidence.
No tool is necessarily perfect. Sometimes a birth certificate can be the
most dangerous of tools to put 100% confidence in without other means of
