Thousands of tools from the Paleolithic era some 325,000
years ago recovered from a site in Armenia have given scientists more data
about how ancient technological developments evolved and spread across the
globe. Researchers from all over the world, including a team
from Royal Holloway, University of London, had reasons to believe they found
strong evidence that an ancient technique called Levallois used to make hunting
weapons was actually invented in Africa and later promulgated to other
continents.
Proof of this theory was provided at a site in Armenina
that yielded found tools related to this kind of technology. Researchers
believe this technology was apparently already part of these ancient Armenian
communities that thrived some 325,000 to 335,000 years ago.
In this part of the world, this technique is called
biface that can be described as something similar to Levallois. These tools
were analyzed and researchers dated the volcanic material used in the tools
discovered in Nor Geghi in Kotayk Province, Armenia.
The discovery of thousands of these ancient tools
provided fresh, new insights that ancient communities were actually more
innovative considering they existed 325,000 years ago. These communities
adapted two different technologies to make tools that were pivotal to their
hunting culture.
As human populations expanded, the Levallois and biface
techniques quickly spread across Africa to Eurasia. After dating the tools
found in Armenia, scientists concluded the biface technique developed
independently and is not a derivative of the Levallois, although the two are
strikingly similar in technique.
Both techniques use a mass of stone shaped into hunting
tools and weapons that resemble sharp, thin flakes. The difference is the
Levallois technique shaped tools by striking flakes from a prepared core
reminiscent of lithic reduction.
On the other hand, the biface technique is more basic. It
uses two sides of a stone to carve out flakes to form bigger tools such as
axes.
This archaeological study was published in the journal,
Science.
