“…For example, the Chutia and Ahom tribes, which were originally affiliated with the Tibeto-Chinese linguistic family, are now semi-Hinduized caste groups speaking Indo-European languages. The ethnic status of Rajbanshi is not clear, and different opinions are advanced regarding this (Dalton, 1872;Risley, 1915;Waddel, 1975;Das et al, 1987). Rajbanshis are hypothesized to be a mixture of different tribal groups (Rabhas, Tiwas, Kacharis, Garos, Karbis, etc.)…”

“…Rajbanshis are hypothesized to be a mixture of different tribal groups (Rabhas, Tiwas, Kacharis, Garos, Karbis, etc.) that were converted to Hinduism and in the process became admixed with certain Caucasoid caste populations (Das et al, 1987). The Ahom and the Rajbanshi, who were originally tribal groups, held a dominant position in terms of economy as well as power.…”

“…Although the Kachari and Sonowal are two divisions of the same tribe, they are not close Chahal et al, 1982;Singh et al, 1982;Papiha et al, 1983). to each other in the multidimensional space. This may in part be due to their geographic isolation, which might have lead to genetic isolation between them (Das et al, 1987). The unexpected position of the Karbis reflects their peculiar linguistic status.…”

“…Ethnically speaking, most of the tribal groups are Mongoloids, whereas caste groups are either Caucasoids or show a mosaic of features of both the ethnic groups. The Mongoloids/Indo-Mongoloids have come to India from different directions at different times and perhaps earlier than the Caucasoids (Das et al, 1987). While the Mongoloids have migrated from eastern, southeastern (Rapson, 1955;Dani, 1960), and central Asian regions, the Caucasoids may have entered from western and northern boundaries of this region.…”

Genetic heterogeneity in northeastern India: Reflection of Tribe–Caste continuum in the genetic structure

We critically examined the gene frequency data for 11 genetic markers commonly available in the literature for 22 populations of northeastern India in the light of their geographic, linguistic, and ethnic affiliations. The markers investigated were three blood groups (A1A2BO, MNS, and Rh), four serum proteins (KM, Gc, Hp, and Tf), and four enzyme systems (AP, AK, EsD, and Hb). The neighbor-joining tree and multidimensional scaling of the distance matrix suggest relatively high genetic differentiation among the Mongoloid groups, with probably diverse origins when compared to the Caucasoid Indo-European populations, which had probably come from relatively more homogeneous backgrounds. Broadly speaking, the pattern of population affinities conforms to the ethno-historic, linguistic, and geographic backgrounds. An interesting and important feature that emerges from this analysis is the reflection of the effect of the sociological process of a Tribe-Caste continuum on genetic structure. While on one end we have the cluster of Caucasoid caste populations, the other end consists of Mongoloid tribal groups. In between are the populations which were originally tribes but now have become semi-Hinduized caste groups, viz., Rajbanshi, Chutiya, and Ahom. These groups have currently assumed caste status and speak Indo-European languages. Therefore, one may infer that what appears to be a purely sociological phenomenon of a Tribe-Caste continuum may well reflect in their genetic structure.

“…However uniform data for several genetic markers on the mongoloid populations of Cis-Himalayan regions and for others far-east or south-east Asian, is not available. In nineteen populations from the above regions the data for ABO, MNSs and Rh systems were collected, however, for 9 of these mongoloid groups additional data for Kell, Duffy, 6PGD, AK, AP, PGM and AP systems were available (Bhasin et al, 1986;Windhof and Walter, 1983;Mourant et al, 1968;Harvey et aI., 1978;Singh et al, 1986;Das et al, 1987;Rouger et al, 1982;Mya-tu et al, 1971;Bhattacharjee, 1975;Bajatzadeh and Walter, 1969;Lin, 1975, andWatanabe et al, 1974). We have thus computed two kinship matrices one based on three genetic systems for twenty populations and the other on the information provided by ten polymorphic systems for ten populations.…”

Serogenetic investigations of Tibetans and Himachalis from Himachal Pradesh, India: Genetic relationship between Tibetans and certain selected mongoloid populations

SummaryTwenty two serogenetic systems were investigated in 115 Tibetans and 128 Himachalis from the state of Himachal Pradesh, northwest India. For eight of the loci (ABO, Rh, MNSs, P, Fy, 6PGD, EsD, and AK) the two populations showed conclusive heterogeneity and their frequency distribution showed that the serogenetic differences between two populations are due to their different racial affliations. The Tibetans were also analysed for their genetic relationship with certain selected populations from the Cis-Himalayan, far east and south Asian regions. The calculations of the Harpending's kinship matrix R and the genetic distances showed that the Tibetans are closer to the mongoloid populations of the Cis-Himalayan region and the differences in the present day population structure of the mongoloid groups of this region are more likely to be due to differential migration, admixture and racial affliation although there is a slight possibility of disruptive selection for certain loci such as 6PGD and AK which showed an exceptionally high value of Canning (6PGD*C) and AK*I genes.

The Indian subcontinent comprises a vast collection of peoples with different morphological, genetic, cultural, and linguistic characteristics. While much of this variability is indigenous, a considerable fraction of it has been introduced through large‐scale immigrations into India in historical times. From an evolutionary standpoint, it is of immense interest to quantify biological diversity in contemporary human populations, to study biological affinities and to relate observed patterns of affinities with cultural, linguistic and demographic histories of populations. Such efforts are intended to shed light on the peopling of India. The purpose of this paper is to present a broad overview of the physical (anthropometric) and genetic diversities and affinities of the peoples of India. I shall also attempt to examine how well biological, particularly genetic, diversities and affinities correlate with geographical, socio‐cultural, and linguistic diversities and affinities. © 1998 Wiley‐Liss, Inc.
