I haven't had the time to review it in depth yet but it looks like you've
brought together all of the relevant E3b research, excepting Cruciani's
latest, which may not matter given his apparent focus in that paper which is
downstream from Paleolithic Balkans. This is most useful and much
appreciated.

I have a question.

There are 78 E3b1a (M78) in the E3b Y-Dna Project and their respective DYS
393 values reveal the following:

4 are 12 (5.13%)
64 are 13 (82.0%)
10 are 14 (12.82%)

Everyone agrees mutations are random events. You note the mutation rate for
DYS 393 is very slow ("1 mutation every 1,316 generations or 26,320 years
with a generation being 20 years or 39,480 years with a generation being 30
years").

Recognizing the numbers found at the E3b Y-DNA project may be too small a
sampling to make any sweeping conclusions, can anything nevertheless be
inferred about the relative age of those haplotypes (nearly 20% of the
total) that do not present a value of 13 at DYS 393?
