What Ancient India DNA Shows

INDIA, September 8, 2018 (YouTube report by NewsX): A newly published paper reports that the skeletal remains of a 5,000 year-old-woman from around 2800 BC were recently found at a Harappan site. Miraculously, one bone from the inner ear held usable DNA. The DNA was found to be unique to the Indian Subcontinent. This finding disputes the common theory that the original inhabitants of India came from the West, but much more likely migrated to the West.

The introduction of the original paper begins: We report an ancient genome from the Indus Valley Civilization (IVC). The individual we sequenced fits as a mixture of people related to ancient Iranians (the largest component) and Southeast Asian hunter-gatherers, a unique profile that matches ancient DNA from 11 genetic outliers from sites in Iran and Turkmenistan in cultural communication with the IVC. These individuals had little if any [Eurasian] Steppe pastoralist-derived ancestry, showing that it was not ubiquitous in northwest South Asia during the IVC as it is today. The Iranian-related ancestry in the IVC derives from a lineage leading to early Iranian farmers, herders, and hunter gatherers before their ancestors separated, contradicting the hypothesis that the shared ancestry between early Iranians and South Asians reflects a large-scale spread of western Iranian farmers east. Instead, sampled ancient genomes from the Iranian plateau and IVC descend from different groups of hunter-gatherers who began farming without being connected by substantial movement of people.
