Ancient DNA (aDNA) research on Indus Valley Civilization sites has generated as many controversies as it has resolved. Critically examine the scientific and socio-political dimensions of such research in the Indian context.

Q. Ancient DNA (aDNA) research on Indus Valley Civilization sites has generated as many controversies as it has resolved. Critically examine the scientific and socio-political dimensions of such research in the Indian context. (15 marks, 250-350 words)

Ancient DNA research recovers genetic material from archaeological human remains to reconstruct ancestry, migration and disease. The transfer of Rakhigarhi's skeletons by the ASI to the Anthropological Survey of India under a fresh MoU [1] renews both the scientific promise and the contestation surrounding such work.

Scientific gains - Rakhigarhi, at ~550 hectares the largest known settlement of the Indus-Saraswati Civilization [1], offers a rare, stratified cemetery record spanning early, mature and late Harappan phases [2]. - aDNA, combined with radiocarbon dating, stable isotope and osteological analysis, illuminates diet, kinship, paleopathology and mobility — questions that pottery and seals cannot answer, especially with the Harappan script undeciphered. - Institutionally, routing remains from an excavating agency (ASI) to a specialised biological-anthropology body (AnSI) [1] corrects a long-standing capacity gap.

Scientific limitations - India's hot, humid climate degrades DNA, so usable genomes are extremely few; conclusions rest on very small samples. - Extraction is destructive and irreversible, consuming finite skeletal material. - The 2019 Rakhigarhi genome study drew criticism for delayed publication and limited data-sharing, weakening independent verification.

Socio-political dimensions - Findings feed directly into the Aryan migration versus indigenous-origin debate, so provisional genetics is often read as settled identity claim. - Even nomenclature is contested — official usage prefers "Indus-Saraswati Civilization" [1] over Indus Valley. - Results touch sensitive questions of caste and tribal ancestry, inviting selective quotation by competing camps. - Custody of human remains raises ethical and consent concerns inadequately covered by the AMASR Act, 1958.

Thus aDNA is a powerful but probabilistic tool whose evidentiary modesty is frequently lost in public debate. Peer-reviewed publication, open data, minimal destructive sampling and a clear ethics protocol for ancient human remains would let institutional collaboration of the Rakhigarhi kind [1] advance knowledge while insulating science from identity politics.
