“…Unfortunately, the most geographically proximal source region, Myanmar, has not been extensively characterized for mtDNA sequence variation but a survey of data from the neighboring states of Northeast India, Malaysia, Thailand, and the Yunnan province of China for mtDNA control and partial coding region data reveals no clear candidate members of M31 0 32 (Fucharoen et al, 2001;Oota et al, 2001;Cordaux et al, 2003;Metspalu et al, 2004;Wen et al, 2004;Oota et al, 2005;Wen et al, 2005;Hill et al, 2006;Kumar et al, 2006).…”

The population genetics of the Indian subcontinent is central to understanding early human prehistory due to its strategic location on the proposed corridor of human movement from Africa to Australia during the late Pleistocene. Previous genetic research using mtDNA has emphasized the relative isolation of the late Pleistocene colonizers, and the physically isolated Andaman Island populations of Island South-East Asia remain the source of claims supporting an early split between the populations that formed the patchy settlement pattern along the coast of the Indian Ocean. Using whole-genome sequencing, combined with multiplexed SNP typing, this study investigates the deep structure of mtDNA haplogroups M31 and M32 in India and the Andaman Islands. The identification of a so far unnoticed rare polymorphism shared between these two lineages suggests that they are actually sister groups within a single haplogroup, M31'32. The enhanced resolution of M31 allows for the inference of a more recent colonization of the Andaman Islands than previously suggested, but cannot reject the very early peopling scenario. We further demonstrate a widespread overlap of mtDNA and cultural markers between the two major language groups of the Andaman archipelago. Given the "completeness" of the genealogy based on whole genome sequences, and the multiple scenarios for the peopling of the Andaman Islands sustained by this inferred genealogy, our study hints that further mtDNA based phylogeographic studies are unlikely to unequivocally support any one of these possibilities.

Indian subcontinent harbours both the human mtDNA macrohaplogroups M and N, of which M is the most prevalent. In this study, we discuss the overall distribution of the various haplogroups and sub-haplogroups of M among the different castes and tribes to understand their diverse pattern with respect to geographical location and linguistic affiliation of the populations. An overview of about 170 studied populations, belonging to four distinct linguistic families and inhabiting different geographic zones, revealed wide diversity of about 22 major haplogroups of M. The tribal populations belonging to the same linguistic family but inhabiting different geographical regions (Dravidian and Austro-Asiatic speakers) exhibited differences in their haplogroup diversity. The northern and southern region castes showed greater diversity than the castes of other regions.

“…The study also found sharing of common mtDNA haplotype across the tribes. Kumar et al (2006) examined the mitochondrial DNA 9-bp deletion/insertion among 31 AustroAsiatic populations (Mundari and Mon-Khmer) and their results suggested multiple origins/migrations and distinctive origin of Austro-Asiatic populations; the Mundari groups (of African origin) probably being the earliest settlers. Also, Kumar et al (2007) assayed Y-STR and SNP markers among 25 AA groups and Southeast Asian populations and detected strong paternal genetic link between the Indian AA and the studied Southeast Asian populations.…”

An understanding of the genetic affinity and the past history of the tribal populations of India requires the untangling of the confounding influences of language, ethnicity, and geography on the extant diverse tribes. The present study examines the genetic relationship of linguistically (Dravidian, Austro-Asiatic, and Tibeto-Burman) and ethnically (Australian and East Asian) diverse tribal populations (46) inhabiting different regions of the Indian subcontinent. For the purpose, we have utilized the published data on allele frequency of 15 autosomal STR loci of our study on six Adi sub-tribes of Arunachal Pradesh and compared the same with the reported allele frequency data, for nine common autosomal STR loci, of 40 other tribes. Phylogenetic and principal component analyses exhibit geography based clustering of Tibeto-Burman speakers and separation of the Mundari and Mon-Khmer speaking Austro-Asiatic populations. The combined analyses of all 46 populations show clustering of the groups belonging to same ethnicity and inhabiting contiguous geographic regions, irrespective of their different languages. These results help us to reconstruct and understand three plausible scenarios of the antiquity of Indian tribal populations: the Dravidian and Austro-Asiatic (Mundari) tribes were possibly derived from common early settlers; the Tibeto-Burman tribes possibly belonged to a different ancestry and the Mon-Khmer speaking Austro-Asiatic populations share a common ancestry with some of the Tibeto-Burman speakers.
