[[ That long apparently branchless ancestral line for the I1 MRCA does not
alter the evidence that the I1 MRCA lived just 4500 years ago.
I am not following developments as much in haplogroup R1b.... as closely as
for haplogroup I, but L21 is downstream (toward the present) from S116, and
much data establishes that S116 and U106 have a node just upstream from them
which is about 4000 years old. So that would make any L21 clade younger
than that. KN ]]
