Although there is no guarantee that G-L91's Most Recent Common Ancestor
(MRCA) lived before Otzi, it would be interesting to see what the TMRCA of
extant G-L91 is. Any estimates?

[[[ While a MRCA is just what the words say, that does not mean that at his
time of existence he was the only person with extremely similar haplotypes.
He would have lived in a population which includes brothers, uncles, male
line cousins, etc. and perhaps numbering in the many dozens or hundreds ---
with this haplotype "cloud" of his near neighbors simply representing
branches of the tree which went extinct before now. Same thing for the
earlier generations; not only was there the direct male ancestors of the
MRCA who are part of the tree, but there were these "clouds" of male
relatives living in each of those earlier generations who were out there on
to-be-extinct branches. An individual like ice man was probably out there
in that cloud (although he logically could have had son(s) with lines of
descent down to today) , and we would need to make an estimate of how far
back before the MRCA of L91 his branch line connects with the tree which
reaches today.

This is a main reason why I personally would rather see the ice man's
extended STR haplotype. Will the extended haplotype be extracted from the
genome by the original research syndicate? Or by anyone? KN ]]]
