When we are talking TMRCA are we talking in terms of genealogy? Or are we talking in terms of clades and sub clades etc going back many millennium or tens of millennium? The reason I ask is because although Anatole Klyosov's method has been repeatedly criticised no one as yet has proven it incorrect in terms of genealogy. I still use the method and it works for me down to a point where I am comfortable that the analysis resulting from his methodology pretty well follows what we know of history of certain family groups down to about 1000AD. I have even read on other forums that it is believed that the methodology is quite sound for the last two millennium. And that was written by one of his chief protagonists on this forum. Why don't we have a TMRCA challenge? We have an extremely well known family group being Clan Donald. They have exhaustive and verifiable genealogies going down to about 1350AD. We know who their common ancestor was and we know exactly when he lived and we know that their family group has three main branches and we even know with reasonable certainty the CA date of the common ancestor date of each of the main branches. So get out your TMRCA calcs and show the methodology and working out and give us some dates using all these TMRCA methodologies. Lets see who is near and who is far.
