That pre-shaped portion is then struck off the core, fully formed.
Levallois style tool-making allows for greater precision and sharper edges.
Blinkhorn expressed skepticism about a number of aspects of the paper.
Even with the supplementary material published concurrently, Blinkhorn felt the authors needed to make a much stronger case for their paradigm-shifting conclusions, including how they define Levallois technology and how they prove that the artifacts fit that definition.
Also of note: at other sites, once Levallois technology was developed, it was embraced and quickly spread through a region.
Blinkhorn, who was not involved in the new study, focuses on both Paleolithic archaeology in general and the prehistory of South Asia in particular.My first professional mentor invented as Nikola Tesla did, and among his many inventions was an engine hailed by a federal study as the worlds most promising alternative to the internal combustion engine.In 1974, as that engine created a stir in the USAs federal government, I began dreaming of changing the energy industry.The shocker: if the analysis is correct, the transition occurred more than 200,000 years earlier than expected based on previous evidence.Tool-making styles, or technologies, are important in the study of human evolution and migration for a couple reasons.
