Description

Stone tools fashioned by early humans up to 385,000 years ago in India could upend a common narrative about the origins of modern humans. The well-known “out of Africa” theory posits that homo sapiens, who originated in East Africa between 400,000 and 300,000 years ago, brought their advanced stone tools as they dispersed beyond Africa to Europe and Asia. However, using new infrared technology, archaeologist Shanti Pappu and her team analyzed stone tools discovered at Attirampakkam, a prehistoric site in south-east India, and dated the artefacts to between 385,000 and 172,000 years ago.


Their analysis, published in the latest edition of Nature, “challenges the view, backed by most researchers, that modern humans brought these technologies to India less than 140,000 years ago,” says Quartz. The findings open up several possible interpretations. One is that homo sapiens were migrating beyond East Africa hundreds of thousands of years earlier than previously thought.
