• This paper was written in order to study the development of stone tool technology throughout the Paleolithic. It finds the technology developed, with the simplest discoveries being made first and more complex discoveries being made later. The chemical structure and the properties of the raw materials determined that stone tools could be useful to humans and over time people learnt to make better and better stone tools. The improvements occurred in an order that was necessary and inevitable, with later improvements building upon earlier improvements, and is an illustration of how increasing human knowledge changes technology and human social and cultural history.
