A breakthrough study published in The Journal of Archaeological Science has introduced a new dating technique utilizing Dysprosium-163 isotopic fractionation. This methodology has allowed researchers to refine the timeline of early Neolithic settlements in India's Mahanadi Basin, pushing back the arrival of sedentary farming communities to approximately 7500 BCE with sub-decadal precision.
The research team, led by geochemists from the Indian Institute of Science, applied this high-resolution chronometry to organic residues found within stratified sediment layers. The results suggest that independent agricultural development in Central India occurred significantly earlier than previously estimated, coinciding with a stabilization of post-glacial monsoon patterns.
