Explanation:
The end of the Neolithic period saw the use of metals. The metal first used was copper and several cultures were based on the use of copper and stone implements. Such a
culture is called Chalcolithic, which means the copper–stone phase. The Chalcolithic people mostly used stone and copper objects, but they also occasionally used low grade bronze and even iron. They were primarily rural communities spread over a wide area with hilly land and rivers. On the other hand, the Harappans used bronze and had urbanized on the basis of the produce from the flood plains in the Indus Valley. In India, settlements relating to the Chalcolithic phase are found in southeastern Rajasthan, the western part of Madhya Pradesh, western Maharashtra, and in southern and eastern India. In south-eastern Rajasthan, two sites, one at Ahar and the other at Gilund, have been excavated. They lie in the dry zones of the Banas Valley. In western Madhya Pradesh or Malwa, Kayatha and Eran have been excavated. The most extensive excavations have taken
place in western Maharashtra. Several Chalcolithic sites, such as Jorwe, Nevasa and Daimabad in Ahmadanagar district; Chandoli, Songaon and Inamgaon in Pune district; and also Prakash and Nasik have been excavated. Pandu Rajar Dhibi is a Chalcolithic site. The people of the Copper–Stone age could not write, nor did they live in the cities, as did those of the Bronze Age. All these elements of civilization figure for the first time in the Indus region of the Indian subcontinent. Although most Chalcolithic cultures existing in a major part of India were younger than the Indus Valley civilization, they did not derive any substantial benefit from the advanced technological knowledge of the Indus people.
