Abstract

The Gond comprise the largest tribal group of India with a population exceeding 12 million. Linguistically, the Gond belong to the Gondi-Manda subgroup of the South Central branch of the Dravidian language family. Ethnographers, anthropologists and linguists entertain mutually incompatible hypotheses on their origin. Genetic studies of these people have thus far suffered from the low resolution of the genetic data or the limited number of samples. Therefore, to gain a more comprehensive view on ancient ancestry and genetic affinities of the Gond with the neighbouring populations speaking Indo-European, Dravidian and Austroasiatic languages, we have studied four geographically distinct groups of Gond using high-resolution data. All the Gond groups share a common ancestry with a certain degree of isolation and differentiation. Our allele frequency and haplotype-based analyses reveal that the Gond share substantial genetic ancestry with the Indian Austroasiatic (ie, Munda) groups, rather than with the other Dravidian groups to whom they are most closely related linguistically.

(b) Plot of population-wise unsupervised ADMIXTURE analysis (K = 9) of world population with a zoom-in of various Indian populations including Gonds. The colour codes of the Indian populations have been given according to their linguistic affiliation shown in Figure 1a.

(a) Plot of mean sharing of chunk counts donated by Eurasian populations to the Gonds; (b) plot of shared drift f3 analysis. The values were calculated as f3 = (X, Y; Yoruba), where X was another Indian population and Y a different Gond group. The colour codes of the populations followed their linguistic affiliation.
