Editor’s Summary: The Austro-Asiatic speaking ethnic group mostly distributes in the Indo-China Peninsular in Southeast Asia and India, and may be the oldest group of the Mongoloid groups, therefore, plays a most important role in the studies on the origin of East Asian. The physical characters of the Austro-Asiatic group are quite various, and the genetic structure is relatively complicated. The diversity of the major Y-chromosome haplogroup of Austro-Asiatic group, O-M95, was analyzed. The result showed that the variance of the Mundari tribes in India, a subfamily of Austro-Asiatic, is much larger than that of another subfamily, Mon-Khmer in Southeast Asia. Therefore, Austro-Asiatic group might have originated from India. However, the sample size of Mon-Khmer populations in this study is rather small, which might have caused a certain misapprehension.

编辑提要：南亚语系人群主要分布于东南亚的中南半岛和印度，可能是蒙古人种中最古老的族群，在东亚人群起源研究中极为关键。这个族群的体质特征非常多样，遗传背景也较为复杂。对其主要Y单倍群O-M95的多样性分析发现，南亚语系的分支，印度的蒙达语族群体多样性远远大于东南亚的另一个分支孟高棉语族群体。因此南亚语系群体可能起源于印度。但是该项研究中涉及的孟高棉语族样本较少，结果或许存在偏差。（李辉，耶鲁大学遗传学系）
