Answer:
Many sociologists and anthropologists have created theories dealing with social and cultural evolutions and declare technological progress to be the primary factor driving the development of human civilization. One in particular Lewis H. Morgan, believed there were 3 major stages of social evolution, these being, savagery, barbarism and civilization.
Within these three it could be divided into technological milestones. Savagery was fire, the bow and arrow and pottery.
