The genetic variation in the R1a clade among the Ashkenazi Levites’ Y chromosome

Abstract

Approximately 300,000 men around the globe self-identify as Ashkenazi Levites, of whom two thirds were previously shown to descend from a single male. The paucity of whole Y-chromosome sequences precluded conclusive identification of this ancestor’s age, geographic origin and migration patterns. Here, we report the variation of 486 Y-chromosomes within the Ashkenazi and non-Ashkenazi Levite R1a clade, other Ashkenazi Jewish paternal lineages, as well as non-Levite Jewish and non-Jewish R1a samples. Cumulatively, the emerging profile is of a Middle Eastern ancestor, self-affiliating as Levite, and carrying the highly resolved R1a-Y2619 lineage, which was likely a minor haplogroup among the Hebrews. A star-like phylogeny, coalescing similarly to other Ashkenazi paternal lineages, ~1,743 ybp, suggests it to be one of the Ashkenazi paternal founders; to have expanded as part of the overall Ashkenazi demographic expansion, without special relation to the Levite affiliation; and to have subsequently spread to non-Ashkenazi Levites.

在外边,没看原文,从yfull上看,Y2619支系主要集中在东欧人群,与阿系犹太人相符合。
另外,Y2619的兄弟支系在亚美尼亚人中发现,倒是与希伯莱人主要源头之一的胡立安相符。

我猜测,早先的祭司阶层主要是希伯莱背景的列维系把控,后来摩西引入埃及一神教(以行割礼为标志),J-P58的亚隆柯恩系接管了祭司领导层,原y2619系逐渐边缘化,直至罗马人重新安置犹太人,原列维系再度在东欧兴起…

犹太人的主要R1a支系实际上是Y2619,在CTS6的下游,CTS6就是M582,伊朗人的四个CTS6全部是CTS6(xY2619).
