Anatomically modern humans settled India in multiple waves of early migrations, over tens of millennia.[1] The first migrants came with the Coastal Migration/Southern Dispersal 65,000 years ago, whereafter complex migrations within south and southeast Asia took place. West-Asian (Iranian) hunter-gatherers migrated to South Asia after the Last Glacial Period but before the onset of farming. Together with a minor number of ancient South Asian hunter-gatherers they formed the population of the Indus Valley civilisation (IVC).
