In the present study, we analyzed 1,686 samples from 31 tribal populations of India for the mitochondrial DNA 9-base-pair deletion/insertion polymorphism, and characterized them based on the relevant mitochondrial DNA coding-region single nucleotide polymorphisms and hypervariable region I motifs, to test the genetic origins of the ethnically and linguistically heterogeneous Austro-Asiatic tribes of India. A comparative analysis of our results with the existing data suggests multiple origins of Austro-Asiatic tribes in India, and particularly the Asian and non-Asian origins of the Mon-Khmer and the Mundari populations. We also identified a novel subclade of haplogroup B in the Mon-Khmer Khasi tribes that distinguishes them from the Nicobarese, indicating two different waves of migration of the Mon-Khmer tribes in India.
