Antony van Leeuwenhoek
Levalloisian refers to a type of stone tool production method that involves removing flakes of stone from a mother stone in a specific way, known as the Levallois technique. This method was widely used during the Paleolithic era, around 100,000 to 50,000 years ago. It is characterized by the removal of flakes in a specific direction, from a predetermined core, to create sharp-edged tools. The Levalloisian technique is considered one of the most advanced and complex methods of stone tool production during the Paleolithic era, and is often associated with early Homo sapiens and other ancient human populations.
