The main cause of shift from Paleolithic(Old Stone Age)to the Neolithic Age(New Stone Age) is that the temperatures were getting warmer, so now this shift was a great impact on the population.. Now people were able to be sedentary because of the warmer climates and make new civizilations, laws, and government structures.
