Topic 02: The Stone Age

1. Phases of the Stone Age — Overview

Stone Age classification is based on tool-making technique, not time alone. As cognitive and manual skills evolved, tools became progressively smaller, more refined, and more specialised.

2. Palaeolithic Age (Old Stone Age)

Covers ~500,000–10,000 BCE. Humans were food-gatherers, not producers — no agriculture, no pottery, no permanent settlements. Lived in rock shelters and open-air campsites near rivers. Climate determined by Pleistocene glacial cycles.

Early Palaeolithic (c. 500,000–150,000 BCE)

• Core tools: large hand-axes (bifacial, pointed/oval), cleavers (flat cutting edge), choppers (single-faced). Material: quartzite.
• Narmada Man (Hathnoora, Hoshangabad, MP): skull cap of Homo erectus found by Arun Sonakia (1982); estimated age 250,000–500,000 BCE — oldest human fossil in India.
• Co-existed with Pleistocene megafauna: rhinoceros, hippopotamus, elephant; cooler, moister climate.

Middle Palaeolithic (c. 150,000–40,000 BCE)

• Flake tools — scrapers, points, borers — struck from a prepared core; lighter and more specialised than core tools.
• Tools could be hafted onto handles — greater hunting efficiency. More diverse tool types = more specialised activities.
• Sites: Narmada, Tungabhadra (Karnataka/Andhra), Son Valley, Belan Valley, Nevasa (Maharashtra).
• No evidence of art or deliberate burial; brain capacity increasing toward Homo sapiens range.

Upper Palaeolithic (c. 40,000–10,000 BCE)

• Blade tools — long, thin parallel-sided flakes; also burins (engraving bone/antler) and bone tools (needles, fish hooks).
• Anatomically modern humans (Homo sapiens sapiens) appear in India; greater cognitive capacity enables art and symbolic thinking.
• Beginning of rock art: earliest paintings at Bhimbetka — Upper Palaeolithic phase.
• End of last glacial maximum (~18,000 BCE); India warming and drying — drove adaptation to smaller tools (→ microliths).
• Key sites: Bhimbetka (MP), Renigunta (AP), Belan Valley (UP).

3. Mesolithic Age (Middle Stone Age, c. 10,000–4,000 BCE)

Transition from pure hunting to early domestication. Defined by the microlith — tiny geometric stone blade. Warmer post-glacial climate caused megafauna extinction, forcing adaptation to smaller, more precise tools for smaller animals.

Microliths — The Defining Tool

• Size: usually less than 5 cm; often 1–3 cm. Geometric shapes: triangles, trapezoids, lunates (crescents), points.
• Material: quartz, chert, chalcedony, jasper — fine-grained stones that flake predictably.
• Composite tools: hafted onto bone/wood handles to make arrows, sickles, knives, harpoons — more efficient than single large tools.

4. Neolithic Age (New Stone Age, c. 6,000–1,000 BCE)

The Neolithic Revolution — shift from food-gathering to food-production — is the most consequential change in human history. It enabled permanent settlements, population growth, surplus, social hierarchy, and ultimately urban civilisation (IVC). In India: Mehrgarh c. 7000 BCE, Gangetic plains ~3000 BCE, South India ~2000 BCE.

Characteristic Features

• Polished/ground-edge stone tools — sharper, more durable; capable of clearing forests for agriculture.
• Agriculture: wheat and barley (northwest), rice (east — Koldihwa, UP, ~7000 BCE, debated), millets (south India).
• Animal husbandry: cattle, sheep, goat; later buffalo, pig, horse — used for food, milk, hides, and traction.
• Pottery: handmade pottery enables grain/water storage — prerequisite for sedentary life.
• Permanent settlements: rectangular mud-brick or wattle-and-daub houses; storage pits, granaries.
• Deliberate burial: under house floors or in cemeteries; grave goods (pottery, ornaments) indicate belief in afterlife.

5. Megalithic Culture (Iron Age Burials, c. 1,500–500 BCE)

Iron Age but prehistoric — no written records. Evidence comes entirely from burial monuments and grave goods. Concentrated in South India (Deccan + Peninsula). Precursor to early Tamil (Sangam) civilisation.

Types of Megalithic Monuments

Grave Goods — What They Tell Us

• Black-and-Red Ware (BRW): diagnostic pottery — black inside/upper portion, red outside/lower portion; wheel-thrown, well-fired. Found in virtually every Megalithic grave in South India.
• Iron tools and weapons: swords, daggers, spearheads, horse-bits, sickles — confirm Iron Age dating.
• Horse remains: horse bones and horse-bits — prestige items; suggest pastoralism and warfare.
• No writing: despite sophistication, no inscriptions — hence "prehistoric."

Key Megalithic Sites

• Brahmagiri (Chitradurga, Karnataka): Excavated by Mortimer Wheeler (1947) — established the landmark three-fold cultural sequence: Stone Age → Megalithic → Early Historical (Andhra/Satavahana). Proved Iron Age Megalithic preceded historical civilisation in South India.
• Adichanallur (Tirunelveli, Tamil Nadu): Hundreds of burial urns containing human skeletal remains, iron tools, copper objects, gold ornaments. Excavated by A. Rea (1902) and later ASI. CCMB DNA studies (2024) confirmed genetic continuity with modern South Indians.
• Hallur (Haveri, Karnataka): Neolithic → Megalithic transition; iron appears alongside polished stone tools in transitional layers.
• Nagarjunakonda (Andhra Pradesh): Megalithic burials alongside later Buddhist remains — multiple cultural phases visible.

6. Prehistoric Rock Art

Rock paintings are historical documents — palaeontological evidence (which animals existed), social evidence (how communities organised), and spiritual evidence (ritual practices). India's rock art tradition is among the richest in the world.

Bhimbetka (UNESCO World Heritage Site, 2003)

• Location: Raisen district, Madhya Pradesh; ~45 km south of Bhopal; Vindhya hills.
• Discovery: V.S. Wakankar (archaeologist, Vikram University Ujjain) discovered rock shelters in 1957–58 while travelling by train.
• Scale: 700+ rock shelters; ~500 contain paintings spanning Upper Palaeolithic to early historical period (~10,000 years of continuous art).
• Subjects: bison (gaur), deer, elephant, rhinoceros, hunting scenes, warriors with bows/arrows, dancing figures, communal celebrations, geometric patterns, mother-child figures.
• Pigments: Red (haematite/iron oxide — most common, most durable), White (limestone/calcium carbonate), Green (chalcedony or malachite), Yellow/Orange (ochre).
• Seven identified periods of paintings — crude Upper Palaeolithic animal outlines → elaborate multi-coloured Mesolithic-Chalcolithic paintings → historical-period horses and chariots.

7. Current Affairs Link

• Bhimbetka conservation threat (2023): ASI and UNESCO raised concerns about moisture damage and algal growth threatening 10,000-year-old paintings; climate change increasing humidity accelerating decay; micro-climate monitoring and chemical stabilisation initiated.
• New Megalithic sites in Kerala (2024): ASI surveys identified new dolmen and menhir clusters in Nilgiris and Wayanad — extending geographic distribution of Megalithic culture further into the Western Ghats.
• Adichanallur DNA study (CCMB, 2024): Ancient DNA from urn burials confirmed site dates to ~1000 BCE; genetic continuity with modern South Indians proved; long-distance genetic connections with Southeast Asia found — evidence of ancient maritime contacts.
• Palaeolithic site near Jodhpur (2025): ASI excavations uncovered Early-Middle Palaeolithic tools dated by OSL to ~300,000 BCE — adds to evidence of dense early human occupation of the Thar Desert region during wetter interglacial periods.
