The tools fall in a class of artefacts called Acheulian that scientists believe were invented by the Homo erectus —ancestors of modern humans — in Africa about 1.6 million years ago.
“This means that soon after early humans invented the Acheulian tools, they crossed formidable geographical barriers to get to southern Asia,” said Michael Petraglia, an archaeologist at the University of Oxford, who is an expert in Asian prehistoric archaeology but was not associated with the Chennai study.
“The suggestion that this occurred 1.5 million years ago is simply staggering,” he said.
