The Neolithic period, or New Stone Age, in India marks a significant transition in human history, characterized by the advent of agriculture, animal domestication, settled village life, and the use of polished stone tools. This period did not begin uniformly across the subcontinent but emerged in different regions at varying times, leading to a diverse distribution of Neolithic sites.

Broadly, Indian Neolithic sites can be categorized into several distinct regional traditions:

1. North-Western India (Kashmir Valley and Pakistan):

   • Mehrgarh (Balochistan, Pakistan): One of the earliest and most important Neolithic sites in South Asia, dating back to around 7000 BCE. It provides evidence of early farming (wheat and barley), animal domestication (cattle, sheep, goat), and settled village life with mud-brick houses. It represents a crucial precursor to the Indus Valley Civilization.
   • Burzahom (Kashmir): Dating from around 2700-1500 BCE, this site is unique for its pit-dwellings (subterranean houses), polished stone tools, bone tools, and evidence of agriculture (wheat, barley, lentils) and animal husbandry. Distinctive features include the burial of domestic animals (dogs) with humans and the use of a coarse grey pottery.
   • Gufkral (Kashmir): Meaning 'potter's cave,' this site also shows pit-dwellings and similar cultural traits to Burzahom, with evidence of early agriculture and animal domestication.

2. Northern India (Ganga Valley):

   • Chopani-Mando, Koldihwa, and Mahagara (Uttar Pradesh): These sites in the Belan Valley are significant for providing some of the earliest evidence of rice cultivation in the world, dating back to around 6500 BCE. They also show evidence of animal husbandry and crude handmade pottery.

3. North-Eastern India:

   • Daojali Hading (Assam): Located in the North Cachar Hills, this site has yielded polished stone tools, pottery, and grinding stones, indicating a Neolithic presence. The Neolithic culture here is characterized by shouldered celts and cord-marked pottery, showing connections with Southeast Asian Neolithic traditions. Other sites like Sarutaru and Marakdola also show similar traits.

4. Eastern India (Bihar, West Bengal, Odisha):

   • Chirand (Bihar): Situated on the banks of the Ghaghara River, Chirand is a significant Neolithic site (around 2500-1500 BCE) known for its extensive bone tools, polished stone tools, microliths, and evidence of agriculture (rice, wheat, barley, lentils) and animal domestication. It also has well-made pottery.
   • Barudih, Kuchai (Odisha), and Pandu Rajar Dhibi (West Bengal): These sites show evidence of Neolithic settlements, often characterized by polished stone tools and early pottery.

5. Southern India (Deccan Plateau):

   • This region has a distinct Neolithic tradition, primarily characterized by ash mounds, which are interpreted as accumulated cattle dung heaps from seasonal cattle pens, repeatedly burnt over time. Key sites include:
     • Utnur, Palavoy, Kodekal, Budihal (Andhra Pradesh/Telangana): These sites are famous for their ash mounds, indicating a pastoral-agro economy with cattle rearing as a prominent activity, alongside cultivation of millets and pulses. They date from around 2500-1000 BCE.
     • Brahmagiri, Maski, Piklihal, Takkalakota, Hallur, Sangankallu, Kupgal (Karnataka): These sites also exhibit ash mounds, polished stone tools, distinctive pottery, and evidence of early agriculture and animal husbandry. They show a gradual transition into the Chalcolithic period.

Key Characteristics of Indian Neolithic Sites:

• Regional Diversity: The Neolithic cultures in India were not monolithic but varied significantly in terms of chronology, tool types, pottery styles, and subsistence strategies across different geographical regions.
• Agriculture and Domestication: The common thread is the shift from hunting-gathering to food production, with different regions cultivating different crops (rice in the east, wheat/barley in the northwest, millets/pulses in the south) and domesticating various animals.
• Settled Life: Evidence of permanent or semi-permanent settlements, often with mud-brick or wattle-and-daub houses, is a hallmark.
• Polished Stone Tools: The use of ground and polished stone tools (celts, adzes) is a defining technological feature.
• Pottery: Handmade pottery, often coarse in the early stages, becomes more refined over time, with distinct regional styles.

In summary, the distribution of Neolithic sites in India reflects a complex and multi-centric origin of agriculture and settled life, with distinct regional adaptations and cultural trajectories that laid the foundation for subsequent cultural developments in the subcontinent.
