It is believed that the method of Stone Age tool production has originated in Africa, but as per a new study, this notion is challenged. The study has evidence of these skills being developed by different populations around the globe independently.
Scientists argue that Levallois technique, a tool making technology was invented in Africa and this method spread eventually to Eurasia, after the migration of humans from Africa. As per a new discovery in Journal Science on the 25th of September, almost 3,000 stone artifacts excavated from NorGeghi1 were examined by the researchers. They found that those artifacts existed between 200,000 and 400,000 years ago, the era having an association with the earliest Levallois tools in Africa.
It was also found by the researchers that people living in the area thousands of years ago used Levallois as well as a more rugged tool making method, termed bifacial technology at the same time. This is evident of these technologies existing together.
Daniel Adler, the researcher of the study stated that “We wouldn’t have found this mixture if the Levallois technology had simply replaced the old method. The communities probably worked out for themselves how to make bifacial tools and then it was a short step to the Levallois method.”
Another researcher of the study, Simon Blockley stated that the artifacts have helped in shedding light on the evolution of Stone Age tools at a time when humans underwent many behavioral and biological changes.
