Classification:

There were many similarities between things or phenomena which led to their classification. The first classifications were in terms of beings (the living), things (articles and substances, or non-living) and passions or actions. Here arose a kind of descriptive  reasoning; if one of a class behaved in a particular way, it was likely that the other in the same class also behaved in  the same way. Thus, the accumulation of knowledge and sifting of experiences  had major impact on primitive biology and chemistry.  Match the three general elements or features of science listed in column  I  with their associated  techniques or practices in column 2 of the table given below. We have done one part of the exercise  'as an example.  

So  far, we have seen that the primitive society had developed a host of techniques for their material comfort. Archaeological records show that towards the end of the Stone Age, primitive human beings were using many facilities such as huts. sewn garments, bags and buckets. They had also evolved technical devices like canoes. hooks and harpoons, spears, slings, throwing sticks, boomerang etc(Fig.). Many of these are actively being used among some present-day tribes such as  the Eskimos, African Bushmen, Australian aborigines and some Indian tribes.
