Ancient tools found in India undermine the “out of Africa” hypothesis

Nature

Scientists have unveiled an extraordinary new analysis of thousands of stone tools found at a site called Attirampakkam in India, northwest of Chennai in Tamil Nadu. Thanks to new dating techniques, a team led by archaeologist Shanti Pappu determined that most of the tools are between 385,000 and 172,000 years old. What makes these dates noteworthy is that they upend the idea that tool-making was transformed in India after an influx of modern Homo sapiens came from Africa starting about 130,000 years ago.

According to these findings, hominins in India were making tools that looked an awful lot like what people were making in Africa almost 250,000 years before they encountered modern humans. This is yet another piece of evidence that the "out of Africa" process was a lot messier and more complex than previously thought.
