单倍群J1是近东地区一个普遍存在的Y染色体谱系。我们报告的频率和YSTR多样性数据的主要亚支（J1 e）。根据453条染色体估计，总的扩展时间为10000年。此外，以前描述的J1（DYS 388 =13）染色体，经常在高加索和安纳托利亚东部人群中发现，是祖先的J1 e，并显示了9000年的扩展时间。对于J1 e，扎格罗斯/金牛座山区显示最高的单倍型多样性，虽然J1 e的频率增加向周边阿拉伯半岛。南方模式的减少扩展时间的估计是一致的序列漂移和创始人效应过程。据预测，第一次这样的迁移发生在新石器时代初期，因此J1 e与整个新月沃地的雨养农业和半游牧牧民的建立相平行。随后，J1 e血统可能参与了牧民向干旱栖息地扩张的事件，与阿拉伯语和其他闪族人口的传播相吻合。欧洲人类遗传学杂志（2010）18，348-353; doi：10.1038/ejhg.2009.166; 2009年10月14日在线发表
Haplogroup J1 is a prevalent Y-chromosome lineage within the Near East. We report the frequency and YSTR diversity data for its major sub-clade (J1e). The overall expansion time estimated from 453 chromosomes is 10 000 years. Moreover, the previously described J1 (DYS388=13) chromosomes, frequently found in the Caucasus and eastern Anatolian populations, were ancestral to J1e and displayed an expansion time of 9000 years. For J1e, the Zagros/Taurus mountain region displays the highest haplotype diversity, although the J1e frequency increases toward the peripheral Arabian Peninsula. The southerly pattern of decreasing expansion time estimates is consistent with the serial drift and founder effect processes. The first such migration is predicted to have occurred at the onset of the Neolithic, and accordingly J1e parallels the establishment of rain-fed agriculture and semi-nomadic herders throughout the Fertile Crescent. Subsequently, J1e lineages might have been involved in episodes of the expansion of pastoralists into arid habitats coinciding with the spread of Arabic and other Semitic-speaking populations.
