The 1st homo species is supposed to be Homo Habilis – (handy man). Who made these flaked tools? An older homo habilis or some of the more advanced ape-like upright walkers that are not related to Lucy?
According to Daily Mail: “World’s oldest tools discovered: Stone flakes made by human ancestor 3.3 million year ago may rewrite evolutionary history”
- Archaeologists have found 20 stones shaped by early humans using ‘simple techniques’ close to the west shore of Lake Turkana in Kenya
- The tools are thought to be 500,000 years older than the first Homo species
- They are also 700,000 years older than other stone tools found previously
- Scientists say it could reshape ideas about how our own species evolved
A set of stone flakes shaped more than 3.3 million years ago could be the world’s oldest tools created by early human ancestors, according to researchers.
Archaeologists have revealed that they have discovered 20 stone flakes and anvils – used to help shape the tools – just west of Lake Turkana in Kenya.
The discovery could fundamentally change the current view of human evolution as – if correct – the date of the stone tools is 700,000 years older than any others found previously.
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.
THE COMPLEX EVOLUTION OF MAN
Scientists behind the discovery now believe ancient species known as Australopithecines – typified by the fossilised skeleton called Lucy – or Kenyanthropus made the tools.
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.
Professor Harmand, who was presenting her findings at the annual meeting of the Paleoanthropology Society, said: ‘The artifacts were clearly knapped [created by intentional flaking] and not the result of accidental fracture of rocks.’
The tools were found at a site known as Lomekwi 3, just west of Lake Turkana in Kenya.
By excavating down into the sandy soil, the team discovered a series of sharp stone flakes and cores – the rocks the stones are knocked off.
They also found anvils that were apparently used to hold the cores as the flakes were struck off. In one case the team were able to fit a flake back to its original core.
A further 130 stone tools were discovered on the surface.
Each of the stones showed distinctive patterns that suggest they had been struck and shaped by human ancestors.
As some tools were locked inside sediment left behind by the receding desert lake, the researchers were able to accurately estimate the time when they were dropped there.
By tracking changes in the Earth’s magnetic field recorded in the sediment, the researchers were able to pinpoint the date to 3.3 million years ago…

“On the western shore of Kenya’s Lake Turkana, a team headed by Meave Leakey and supported by the National Geographic Society has discovered the 3.5 million-year-old fossil remains of Kenyanthropus platyops, which is most likely a completely new genus and species of early human ancestor…” continued on link.
