A new study published in the Archaeological Science Review has introduced a refined Zircon-fission track dating methodology that provides unprecedented chronological precision for tropical archaeological sites. By applying this technique to volcanic ash layers interbedded with Neolithic tools in the Godavari Basin, scientists have established that permanent agrarian settlements in the region appeared as early as 3800 BCE.
This new timeline pushes back the established chronology of the Southern Neolithic by nearly 400 years. The study demonstrates that the transition to sedentary life in Peninsular India was contemporaneous with early urban developments in the Northwest, suggesting a much more interconnected and rapid spread of Neolithic lifeways across the subcontinent than current models suggest.
