What DNA Says About Aryan Invasion Theory -2

From the latest batch of papers.

[color="#FF0000"]More surprising is the status of Y-chromosome haplogroup R1, [/color]which, unlike mtDNA haplogroup I, [color="#FF0000"]is not indigenous to West Eurasia but appears to have originated in South Asia, [/color]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][color="#2E8B57"][[[reference to Spencer]]].[/color] Two major subclades of R1 appear in Europe: R1b in the west and R1a in the north-east. It has been suggested that R1b mirrors mtDNA haplogroup H and the forerunner of V in arriving from the east shortly after the LGM. Then, with the Late Glacial, its main subclade R1b1b2 expanded into western and central Europe [66,67,68], with a possible expansion at the same time from Anatolia [69]. R1a might then represent an expansion from an eastern refuge, perhaps in the Ukraine, although it might also have been the result of more recent dispersals [62,66,70,71,72].
