[[[[ I don't know of any "commonly previous thoughts" that S21 MRCA was
older than S28 MRCA? What gave you that impression? KN ]]]]]

[[[[ In any event, very robust correlations are difficult to make about when
the various MRCAs for present day clades broke out and any "whys" for those
break outs; but the most robust one I think I see across all the haplogroups
in Europe is that generally the more northerly we see the present day
populations located, the more recent the MRCA for the population KN ]]]]]
