VERIA:About 20 stone tools shaped by early human ancestors more than 3.3 million years ago have been unearthed close to the west shore of Lake Turkana in Kenya.
The tools believed to be the world’s oldest stone tools, are thought to be 700,000 years older than any others found previously.
The discovery, which could fundamentally change the current view of human evolution, mean that ancient human ancestors were creating tools hundreds of thousands of years before the appearance of the first Homo species.
Many experts have long believed that it was the use of stone tools by early species of Homo like Homo habilis and Homo erectus that helped set them apart from other human-like species.
Professor Sonia Harmand, a palaeolithic archaeologist at Stony Brook University in New York who led the team that discovered the tools, said they stumbled across them by accident.
The team had been searching for the site where a controversial human relative called Kenyanthropus platyops had been discovered in 1998. But after taking a wrong turn they came across another area and spotted what looked like stone tools on the sandy surface.
Each of the stones showed distinctive patterns that suggest they had been struck and shaped by human ancestors.
