Abstract

Most Indian groups descend from a mixture of two genetically divergent populations: Ancestral North Indians (ANI) related to Central Asians, Middle Easterners, Caucasians, and Europeans; and Ancestral South Indians (ASI) not closely related to groups outside the subcontinent. The date of mixture is unknown but has implications for understanding Indian history. We report genome-wide data from 73 groups from the Indian subcontinent and analyze linkage disequilibrium to estimate ANI-ASI mixture dates ranging from about 1,900 to 4,200 years ago. In a subset of groups, 100% of the mixture is consistent with having occurred during this period. These results show that India experienced a demographic transformation several thousand years ago, from a region in which major population mixture was common to one in which mixture even between closely related groups became rare because of a shift to endogamy.

  • Previously, the West Eurasian population known to be the best proxy for East African West Eurasian ancestry was present-day Sardinians, who resemble Neolithic Europeans genetically.

    From Genomic insights into the origin of farming in the ancient Near East (2016) · cites this paper as [33]

    The F4 Ratio Estimation section identifies Georgians as a close West Eurasian comparison for Ancestral North Indian ancestry, not for East African ancestry. The Simulations table includes Sardinians as a reference population, but does not identify them as the best proxy for East African West Eurasian ancestry. Searches for Sardinians and Neolithic Europeans found no passage establishing the claimed genetic resemblance. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
