The Neolithic sites were spread over almost all the regions of Indian subcontinent. In the northwestern region Mehrgarh is a classic site in the Kachi plains of Baluchistan. The excavations at Mehrgarh have revealed the evidence of houses built by Neolithic people.
These were built of sun-dried bricks. These houses were divided into small rooms. The evidence of cultivation of crops like wheat, barley and cotton were discovered from here.
The important sites in Kashmir Valley include Burzahom and Gufkral. The dwelling pits, either circular or rectangular, at these sites form an important feature of Neolithic culture. The Belan Valley along the edge of Vindhyan plateau near Allahabad in Uttar Pradesh also has many Neolithic sites such as Koldihwa and Mahagara. The Neolithic tools (both stone and bone), pottery, other artefacts, floral and faunal remains have been found from these sites
In Bihar and mid-Gangetic Valley region Chirand is the most popular Neolithic site. Several Neolithic sites are present covering the hills of Assam, Meghalaya and Nagaland. The tools like Neolithic celts, small ground axes along with the remains of pottery have been found from this area.
In South India the Neolithic settlements were discovered along the rivers Bhima, Krishna, Tungabhadra and Kaveri. Some important sites are Sanganakallu, Brahmagiri, Maski, Piklihal, Hallur in Karnataka; Utnur, Nagarjunakonda, Budihal in Andhra Pradesh; and Paiyampalli in Tamil Nadu. These sites have yielded dwelling pits along with the evidence of cultivation of cereals and domestication of animals. Millet (Ragi) was one of the earliest crops cultivated by the villagers of South India.
