Levallois technique

The Levallois technique is a unique type of stone knapping developed some 250,000 to 300,000 years ago during the Middle Palaeolithic period. It was used by the Neanderthals in Europe and by modern humans in regions like Levant. It is named after 19th century flint tools found in the Levallois-Perret suburb of Paris, France.
Based on the complexity of the Levallois technique, a new hypothesis made a conjecture that the global interactions may have existed as early as 400,000 years ago. The hominis of the Old World used the same Levallois technique across geographies to carve out tools. Since the process is complex, it could have been learned only through close and prolonged observations and interactions.
