The Upper Paleolithic Revolution occurred during the final era of the Late Stone Age between 10,000 and 50,000 years ago, just before the practice of agriculture became widespread. Research also indicates that this is the period in history when modern Homo sapiens sapiens (Cro-Magnons) began to replace the Neanderthal humans. This revolution is characterized by significant changes in human behavioral development that laid the foundation for modern human civilizations.
