It has been found that hominids invented and used stone tools on multiple occasions as per the latest findings in the research led by Arizona State University and George Washington University. The collection of 327 stone tools, which were found during the research, has believed to be carved more than 2.58 million years ago. Published in the research study ‘Proceedings of the National Academy of Science’, these findings have been credited as the primary evidence of sharpening stones used to create specific stone tools.
The collection of “Oldowan” tools were found in the Afar region of north-eastern Ethiopia. The prehistoric humans could have created these tools by chipping off bits of stone to carve up the meat. Earlier the Oldowan tool was found in Gona in Ethiopia which is believed to be carved 2.56 million years ago.
The tools were found near Homo, the oldest fossil, which is at an excavation site known as Bokol Dora 1 or BD 1 in Ethiopia. Geoarchaeologist Vera Aldeias from the University of Algarve in Portugal said, “These tools were dropped by early humans at the edge of a water source and then quickly buried. The site then stayed that way for millions of years.”
David Braun who collaborates with the research said, “Given that primate species throughout the world routinely use stone hammers to forage for new resources, it seems very possible that throughout Africa many different human ancestors found new ways of using stone artifacts to extract resources from their environment.”
There have been other findings which prove that the prehistoric humans were manufacturing and using tools for one million years.
