Archeologists are examining more than 3,000 stone artifacts from an Armenian archaeological site. They were surprised to note that the early hominids were using tool making methods akin to those used by early Homo sapiens in Africa.
It was believed that in between 200,000 to 300,000 years ago in Eurasia and in Africa ancient humans were perfecting tools using a method which is known as the Levallois technology. Levallois technology name stuck because it was first discovered in Levallois in France. The Levallois technology involves shaping stone by knocking off flakes from a piece of stone called core.
The ancient humans developed a complex stone tool production method and the resulting flakes of different sizes had all their edges sharpened and refined into tools which were small and easy to carry.
These advance techniques of crafting stone tools once thought to be perfected in Africa could have been invented independently according to a new study. The latest findings explain that ancient technology did not spread across the world due to the exodus of humans from Africa but could have been invented independently.
Bifacial technology preceded the Levallois technology in which a mass of stone is shaped by removing flakes to produce a tool like a hand axe and most of the flakes are discarded. The Levallois technology was more favorable because it produced lesser waste.
It was believed that Levallois technology was invented in Africa and the invention spread across Eurasia when the humans migrated in an exodus from Africa. The new technology replaced the earlier bifacial technology.
However Archaeologists have unearthed evidence that Levallois technology was known in Eurasia and the technology arose independently outside Africa. The researchers said that the stone artifacts made from the volcanic rock revealed that people there used both bifacial and Levallois technology and gradually phased out the bifacial technology.
