[PDF] Deep common ancestry of Indian and western-Eurasian mitochondrial DNA lineages | Semantic Scholar

The Y-chromosomal data consistently suggest a largely South Asian origin for Indian caste communities and therefore argue against any major influx, from regions north and west of India, of people associated either with the development of agriculture or the spread of the Indo-Aryan language family.

Non-L mtDNAs testify for Eurasian lineages that have enriched the African maternal pool at different timeframes: i) Near and Middle Eastern influences in Upper Palaeolithic, probably link to the spread of Afro-Asiatic languages; ii) particular lineages from West Eurasia around or after the glacial period; iii) post-glacial mtDNA signatures from the Franco-Cantabrian refugia, that have crossed the Strait of Gibraltar

Analysis of variation at DNA level in contemporary human populations of India has provided evidence that mitochondrial DNA haplotypes based on RFLPs are strikingly similar across ethnic groups of India, consistent with the hypothesis that a small number of females entered India during the initial process of the peopling of India.
