Material Basis of Primitive Life:

In  the primitive society, human beings invented tools for catching animals, and for collecting, transporting and even preparing food.  They looked for protection against  the elements of nature in  the form of clothing and shelter  in the caves. The material basis of primitive life is reflected in  the tools and other artefacts that have been  found in archaeoldgical surveys. The tools are all made up of  stones.  This is why  that era has been named as',the Stone Age. Implements and Tools Stones were shaped to suit a specific purpose like digging, throwing or scraping.  Their shapes and sizes became standardised over a period of  time in different gkographical regions. These shapes and sizes becade so stable that they continue  in some tribal societies even today.  You may  like to compare  the tools used today for hunting, digging or shaping materials with those of the Stone Age shown in  Fig.
