近年来，对来自南亚和世界其他地区的人类进行的线粒体DNA和Y染色体研究揭示了关于现代人类在更新世晚期（大约4万至6万年前）从非洲沿南部沿海路线在世界上居住的新见解。分子研究和考古记录都与南亚种姓和部落人口遗传结构的本土分化基本一致。种姓和部落内部和之间的众多社会界限造成了高度的内婚，沿着遗传漂变、分裂和长期隔离等几种进化力量的影响，使印第安人口保持多样性，彼此之间以及与其他大陆人口之间保持距离。本文试图总结最近的遗传学研究印度种姓和部落人口的重点信息嵌入在社会定义的印度人口结构。(c)2006 Wiley Periodicals，Inc.
In recent years, mtDNA and Y chromosome studies involving human populations from South Asia and the rest of the world have revealed new insights about the peopling of the world by anatomically modern humans during the late Pleistocene, some 40,000-60,000 years ago, over the southern coastal route from Africa. Molecular studies and archaeological record are both largely consistent with autochthonous differentiation of the genetic structure of the caste and tribal populations in South Asia. High level of endogamy created by numerous social boundaries within and between castes and tribes, along with the influence of several evolutionary forces such as genetic drift, fragmentation and long-term isolation, has kept the Indian populations diverse and distant from each other as well as from other continental populations. This review attempts to summarize recent genetic studies on Indian caste and tribal populations with the focus on the information embedded in the socially defined structure of Indian populations.
