But a new study, published in the journal Currently, some of the biggest questions facing palaeoanthropology involve trying to work out how and when early humans left the continent. But a new study, published in the journal , suggests early humans may have left Africa much earlier than Middle Palaeolithic (200,000 to 40,000 years ago) in Tamil Nadu, India.Surprisingly, the tools date back to 385,000 years ago—which is around the same time as this technology is thought to have first developed by archaic or possibly modern humans in Africa.

The site appears to have been sporadically occupied by apes and early hominins predating infrared-stimulated luminescence – which pinpoints the last time that sediment grains were exposed to light – the authors determined that the silts and gravels which contain the tools date to between 385,000 and 172,000 years ago.
