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.
