Kao što sam pre neki dan obećao, preneću vam neke delove iz istraživanja Vadima Verenicha o hg I2a1b1-Dinaric, koje je on prikazao na forumu www.forumbiodiversity.com. Iako sam se relativno skoro uključio u ovu temu, pročitao sam sve od početka i ne sećam se da je neko govorio o tome.
Prvo, evo njegovog rezimea:
This is just a small summary of what I have learned about I2a2a-Dinaric subclade over the past two years. I will start with the obvious facts:
1. TMRCA (time to the most recent common ancestor) of I2a2-Dinaric clade members is 2500-3000 ybp (years before present), and this etimated age is already a matter of consensus among DNA-genealogy hobbysts.
2. The structure of I2a2-Din subclade's phylogeny have shown how intimately the lack of distinctive clusters/varieties within I2a2-Dinaric subclade is linked to the recent expansion of that subclade. KN has identified at least four "random" clusters of I2a2-Din (Din-N, Din-S, Croat and Jewish) with "weak" statistical properties. No solid clusters within I2a2-Dinaric have been found to date. In KN's own words "I2a2-Dinaric is a hard nut" (i.e there aren't reliable statistical divisions). Such a pattern is indicative of recent "molecular" origin.
3. My observations indicate that the branching part of I2a2-Din tree (a part of tree, that leads to "bushy pattern" © Nordtvedt) has a average molecular age 1200-1500 years before present.
I found that 1500-1700 years is also a mean distance to the common ancestor of two unrelated I2a2-Dinaric haplotypes/
4. The striking similarity of I2a2-Dinaric haplotypes, observed in inter-population (geographic) comparision. I propose that striking "matching" pattern, observed in haplotypes is consistent with the scenario of recent expansion. It might also explain a surprisingly high amount of Balkan DNA matches for Ukrainian, Polish, Slovakian members of I2a2-Din subclade and vice versa.
5. The molecular diversity of I2a2-Dinaric haplotypes in Slovakia, Ukraine and Hungary is paradoxically higher than expected (considering the impressive high frequencies of I2a2 lineage in Balkan region).
6. Two recent foundation events in I2a2-Din-Jewish (800 ybp) and I2a2-Din-Croat-DYS19=14 (600 ybp) clusters.
And here is one sentence that must be said to sum up the whole set of arguments: the expansion of I2a2-Dinaric clade occured c. 1200 -1500 years before present.
Malo kasnim vremenski sa komentarima.
Od Verenicog rezimeja, odvojio bi bitnu stvar, koja potvrdjuje ono sto smo dosada mislili :

Pa nije nista paradoksalno, ako se I2a-din rodio oko granice Slovacke i Ukrajine. Ta veca varijansa jeste dokaz da I2a-din nije sa Balkana otisao severno, nego da se I2a-din rodio na severnim karpatima i spustio na Balkan.
A tako mlad, ne znam kako jemogao pre Slovena doci.
