Abstract
DNA samples from 160 unrelated individuals belonging to five Dravidian tribal populations of southern India were analysed for ten mitochondrial DNA(mtDNA) restriction site polymorphisms (RSPs) and one insertion/deletion polymorphism. There is extensive sharing of mtDNA haplotypes among all the tribal populations studied, indicating that there was a small femal founding population in India. The 9-bp deletion analysed was observed only in the Kadar population with a low frequency. The Asian-specific haplogroup M is found at a higher frequency in all the populations, thus supporting the hypothesis that this haplogroup U is also found in all the populations and it is consistent with the theory that Dravidian-speaking populations were more wide-spread in India and that the Aryan-speakers pushed them to their present habitat.
