A couple of things I notice on the chart:
- R2 is shown as younger than R1/R1a/R1b, which I think is probably true.
- An Asian source for all Europeans - excluding haplogroup E.

Boss,
ReplyDeleteI don't think it has so much with age. The originating locus for the westwards migrations shifts progressively Eastwards:
R1b C.Asia
R1a Afpak
R2 Bengal
Nichols notices this as well. Kentum migrates out from C Asia. Iranian from Afpak. Lastly the classical sanskrit/mittani/Sindoi migrations from interior India.
It seems to be saturation-dependent migration out of India. Saturation of the euro periphery.
It is painfully obvious that there was a layered settlement of eurostan from Asia:
ReplyDelete1. Paleolithic IJ from ME
2. Holocene R from Greater India. Holocene N from East Asia
Something minor:
K and F expansion in interior Asia is carelessly backdated from the seminal colonization of eurostan at 40K. Fine. If the becharas want to treat themselves to some stale wine, let it be...
Boss,
ReplyDeleteanother emerging trend.. they don't care about y-lines anymore. haplogroup U, H and other likes are the rage these days..
This must be the equivalent of waterboarding. :D
ReplyDelete>>>>>More surprising is the status of Y-chromosome haplogroup R1, which, unlike mtDNA haplogroup I, is not indigenous to West Eurasia but appears to have originated in South Asia, possibly in the early settlements associated with the southern route dispersal [64]. This appears better substantiated than the alternative suggestion of a Central Asian origin [65]. <<<<<<<
ReplyDeleteNothing to see here, folks. let's move along now.
I still think R2 would be younger because it just does not exist in Europe except for a few Jewish outliers. The west to east spread of R1b, R1a and R2 respectively in South Asia is something to consider but then if migration westward occurred at around the same time we should find at least some R2 among the non-Jewish population in Europe which is not the case. I am pretty certain R2 is younger than R1a and R1b even though R2 variation suggests that its older. However, another possibility is that R2 was restricted to east and south India for a long time and migrations did not occur for any number of reasons.
ReplyDeleteAs far as eurostani arrogance, defiance and pig headedness goes - well, kya karein. They'll end up dismissing anything that doesn't suit them in any case.
It matters little. R1a1 expanded out of AfPak in the Holocene and contributed to a majority of uberstani lines. If N expanding out of E Asia is correlated with Uralic, then R1a1 expansion out of AfPak must be the IE migration.
ReplyDeleteIf the situation were reversed in the slightest, then we would be bombarded endlessly with witzelian and dienekian articles triumphantly proclaiming AIT.
