A Consilience of Genomic, Archaeological and Astronomical Proxies: Resolving South Asian Chronology via the Latitudinal Migration Hypothesis.

This paper resolves the 3,000-year chronological discrepancy in South Asian proto-history by introducing the Latitudinal Migration Hypothesis. By shifting the analytical framework from Time (precession) to Space (latitude), we identify the Vedic oral tradition as a high-fidelity 'Flight Data Recorder' of a Bronze Age migration. We anchor the chronology to a biological 'hard ceiling'—the R1a-Z93 genomic pulse—and the Sinauli archaeological horizon (c. 2000 BCE). Utilizing geometric modeling and atmospheric extinction parameters, we prove that 'impossible' astronomical observations in the Mahābhārata (the falling of Abhijit/Vega and the rising of Agastya/Canopus) are physically consistent with observations made between 50°N and 65°N. This study provides a math-based reconciliation of genomic, archaeological, and astronomical proxies.
