Saga from the Prehistoric Graveyards: Ancient DNA Technology is rewriting the population history of the Indian subcontinent
Bibliographic record
Abstract
The present population of the Indian subcontinent has been formed by the Homo sapiens who migrated to this land as a part of the Out of Africa (OOA) migration [approximately 65000 years before present (YBP)] and multiple other migrations viz., the so called ‘Aryan’ migration (3500-4000 YBP). Analysis of the Indus Valley Civilization fossils using recently developed ‘ancient DNA technology’ revealed no Pontic steppe DNA (Aryan / Yamnaya DNA) and they are found to be the genetic stock of the most people living in subcontinent today. In contrast, at least 17.5% modern North Indians (mostly Brahmins) bear the Y chromosome marker (R1a haplogroups) from the Eurasian steppe, indicating a heavily sex biased (male dominated) infiltration during Bronze age. This finding substantially established Aryan migration in the Indian subcontinent.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
