Stone Ages or the savagery and the Barbaric Ages

Old stone Age or the Palaeolithic period begins somewhere between 5,00,000 and 2,50,000 years ago. Human beings lived entirely on hunting, fishing and gathering, as depicted by
Morgan " a stage of savagery".

The New Stone Age or the Neolithic period began some 10000 to 12000years ago. In this age human beings were able to increase, and thus control to some extent the supply of food. They did this by cultivating cereals or breeding animals. It is termed as " the Barbaric Age"
It is during this period that pottery, the technique of spinning wool, flax and cotton threads came to use. Finally, fashioned stones axes sharpened by grinding also made their appearance at this time. From archaeological remains of this period, one finds a large number of flint arrow heads, bone harpoons and dart heads.
The people of the Palaeolithic Culture used tools and implements of stone, roughly dressed by chipping. These tools a
The burin, with the working border made by the meeting of two planes, was used for engraving on soft stones, bones or the wall of rock shelters and caves.
Examination of the soil of the Palaeolithic sites and other evidence has revealed a correlation be­tween prevailing climates and the successive levels of tool technology that constitute the Palaeolithic.
The Rohri Hills in Jacobabad (Pakistan), located at the Indus River margins of the Great Indian Desert (Thar), contain a group of sites associated with sources of chert, a principal raw material for tool- and weapon-making.
Evidence of these chert bands in alluvial plains, otherwise largely devoid of stones, suggests the development of Jacobabad as a major factory centre in the Palaeolithic age. Palaeolithic tools exhibit adaptations for working particular materials, such as leather, wood and bone.
