The finding suggest that an advanced toolmaking culture was developing in India long before the arrival of modern humans

Researchers have found thousands of stone tools buried in an archaeological site in southern India. The ancient tools are around 385,000 years old and might push back the date when modern humans left Africa.

Humans migrated out of Africa and spread to other parts of the world millions of years ago. They reached Asia around 60,000 years ago.

Previous researches suggest that Middle Paleolithic tools – primitive axes, knives and cleavers - did not come to India before 140,000. With the discovery of stone at the site of Attirampakkam, it appears that an advanced toolmaking technology was developing in the region long before modern humans are thought to have arrived there.

Since no human remains were found alongside the artifacts, researchers are not sure whether the tools were made by Homo sapiens or some evolutionary cousin. If they were produced by members of our species, it might rewrite the history of human evolution.

“We don't know who made these tools nor do we know how much local influences prevailed as compared to possible influences from dispersing hominins out of Africa.” Archeologist Shanti Pappu and her team from the Sharma Centre for Heritage Education in India, who discovered stone tools discovered at Attirampakkam, told CNN.

The discovery hints at “complex interactions” between the hominins in India and their relatives around the world and represents a transition in tool making. It also supports the idea that ancient humans left Africa in multiple waves.

“At Attirampakkam, the gradual disuse of bifaces, the predominance of small tools, the appearance of distinctive and diverse Levallois flake and point strategies, and the blade component all highlight a notable shift away from the preceding Acheulian large-flake technologies. Authors wrote in the study.

“These findings document a process of substantial behavioral change that occurred in India at 385 ± 64 ka and establish its contemporaneity with similar processes recorded in Africa and Europe.”
