Prehistory: Human Origins and Stone Age Cultures
In this note
1. Studying the deep past
- Why it matters: early human history tracks biological evolution (gradual physical-genetic change from the australopithecines — australis "southern", pithecus "primates" — to Homo sapiens) and cultural evolution (adaptation to climate and environment through tools, techniques and technology) across the Quaternary Period — the last 26 lakh (2.6 million) years, including the present.
- Hominins = the group including modern humans and our early human-like ancestors — defined as tool makers. The earliest stone tools, c. 3.3 million years ago, mark the start of distinctively "human behaviour" (animals lack the cognitive ability to make such tools). Tools are called "extra-corporal limbs" — extensions of the body doing what hands alone could not.
- Evidence base: discarded tools buried in the earth's upper layers, and fossils — preserved remains, traces or impressions of plants, animals or humans that turned to stone under layers of earth over thousands or millions of years. Because there is no writing, all dating is approximate (see Section 8).
- Periodisation is technological: Palaeolithic → Mesolithic → Neolithic → Chalcolithic → Bronze Age, each defined by tools, subsistence and settlement. (Palaeo = old, lithic = stone.)
2. Our ancestors and the journeys out of Africa
Our earliest ancestors evolved and lived in Africa; the earliest settlements span Africa, Asia and Europe — together the 'Old World.' Different human ancestors co-existed.
| Species | Range and dates (per Class 9, Ch 4 "Early Humans") | Tools / traits |
|---|---|---|
| Homo habilis ("handy man") | Africa — Olduvai Gorge, Tanzania and Kenya | chopper stone tools |
| Homo erectus (upright, bipedal) | Eastern African Rift Valley, c. 2 mya; first hominin to exit Africa ~2 mya, spreading into Asia and Europe between 2 and 0.5 mya | handaxes and cleavers |
| Homo neanderthalensis | Europe and Southwest Asia, till c. 40,000 years ago | Middle Palaeolithic flake tools |
| Homo sapiens | evolved in Africa c. 300,000 years ago; major exit c. 125,000 years ago; reached Australia and the Americas between 50,000 and 12,000 years ago; the only human species alive today | blades, microblades, complex technologies |
- Trap to remember: the first hominin out of Africa was Homo erectus, not Homo sapiens; the erectus dispersal is read from African-type handaxes/cleavers found across Asia and Europe.
- Class 6, Ch 4 "Timeline and Sources of History" adds the framing: modern humans have existed ~300,000 years — a long span, yet a tiny fraction of Earth's history; at critical points humanity could have gone extinct like other species.
3. Palaeolithic hunter-gatherers
- Indian evidence: the subcontinent's oldest human settlement dates to about 2 million years ago. Key Lower Palaeolithic sites: Attirampakkam, Tamil Nadu (c. 1.5–1.7 mya) and Isampur, Karnataka (c. 1.2 mya) — animal fossils plus large cutting tools (handaxes, cleavers) and scrapers and choppers of quartzite and limestone, used to chop meat, dig tubers, scrape skins and cleave bones for marrow.
- Toolkit progression: smaller tools — scrapers, borers, points (tipping projectiles for efficient hunting) → the bow and arrow, plus parallel-sided blades and microblades struck from glassy-textured rock (razor-sharp when fresh) for hunting small game. The burin (engraver) incised symbolic marks on bone and shell (including ostrich eggs); microblades were hafted in handles.
- Symbolic behaviour (associated with Homo sapiens): paintings on cave and rock-shelter walls, pigments for body decoration, and the first beads — of stone, bone and shell.
- Life in bands (Class 6, Ch 4 "Timeline and Sources of History"): hunter-gatherers lived in groups in temporary camps, rock shelters and caves; used fire; spoke languages now lost; held beliefs about natural elements and possibly an afterlife; made ornaments (stone/shell beads, animal-teeth pendants) and exchanged them with other bands. Rock paintings survive in hundreds of caves worldwide.
- Caution on gender roles: the chapter warns that the "natural"-looking division of labour in reconstructions is not necessarily accurate — women may have painted the rock art, men may have cooked or minded children; evidence is limited.
4. Mesolithic hunter-gatherers
- Around 12,000 years ago the climate warmed — the end of the last Ice Age (which had lasted from over 100,000 to about 12,000 years ago, Class 6, Ch 4 "Timeline and Sources of History"). Forests and grasslands spread into formerly ice-covered areas, offering small game, fish and edible wild grains.
- Result: the first-ever population explosion in human history.
- Technology and economy: varied microlithic tools; aquatic foods — marine and freshwater — with fishing as the mainstay of subsistence.
- Culture: art activity flourished; caves and rock shelters were reoccupied. Bhimbetka (Madhya Pradesh) — a World Heritage Site — holds hundreds of painted rock shelters with Mesolithic and even earlier occupation.
5. The Neolithic Revolution
- As hunter-gatherers learned seasons and food resources intimately, there was a gradual transition to food production — the Neolithic Revolution. Its hallmark: domestication of select plants and animals (bringing them under human control) and the creation of new breeds through cultivation and husbandry.
- Diagnostic shifts: tools now made for food production and processing, not just procurement; earthenware pottery in varied shapes and sizes; and the first village settlements — laying the foundation of the later urban revolution. With surplus food, communities grew in size and number (Class 6, Ch 4 "Timeline and Sources of History"), settling near rivers for water and more fertile soil.
- "Revolution or gradual change?" — the chapter itself calls the transition gradual yet revolutionary in consequence: surplus food and material goods are what made civilisation possible.
- The transition was staggered across the world (Class 9, Ch 4 "Early Humans"'s chart): different regions domesticated different plants and animals at different times.
- Growing social complexity (Class 6, Ch 4 "Timeline and Sources of History"): leaders or 'chieftains' responsible for the people's welfare; no individual ownership — land collectively sown and harvested; hamlets grew into villages exchanging food, clothing and tools; networks of communication and exchange formed, and some villages became small towns. New technologies followed: pottery, then metal — copper first, iron later.
6. Neolithic and Chalcolithic in the subcontinent
- The subcontinent shows regional variation in when farming began.
- Mehrgarh (on the Bolan River, in present-day Pakistan): the subcontinent's oldest Neolithic site and earliest agricultural village, c. 7000 BCE. Its people:
- built handmade sun-dried brick houses and granaries;
- buried their dead in graves;
- made ornaments of semi-precious stones — lapis lazuli, carnelian — and shell;
- cultivated wheat and barley; raised sheep, goats and Indian cattle — notably the zebu humped bull;
-
were the first to make copper objects, entering the metal age — Chalcolithic by c. 4000 BCE — laying the basis for the Bronze Age Sindhu–Sarasvatī civilisation around 3500 BCE (the chapter's preferred name for the Harappan civilisation).
-
Southern Neolithic: Sanganakallu (Karnataka), a Neolithic site atop a granite hill, dated c. 2000 BCE.
- By 2500 BCE, Neolithic agro-pastoral communities occupied most of the subcontinent — cattle, sheep and goat herding with cereals, millets and pulses — in places interacting with contemporary Chalcolithic cultures.
7. Towards civilisation: the Early Harappan threshold
- Copper tools in the fertile alluvial plains of the Indus and Ghaggar-Sarasvatī basins raised productivity and prosperity. From 4000 BCE onwards, large-scale pottery production with diverse regional styles marks the early Chalcolithic sites of Baluchistan and the two river basins.
- Chapter claim to flag: some radiocarbon dates suggest that at sites in the dried Sarasvatī river belt — Bhirrana and Kunal — a Pre-Harappan phase began between 7000 and 5500 BCE. This early dating, and the "Sindhu–Sarasvatī" framing itself, are the new NCERT's positions; cite them as such.
- Early Harappan continuity (regional styles evolving into standard features by c. 2500 BCE): pottery traditions, semi-precious stone beads, shell bangles, terracotta objects, copper working. Early bead production at Harappa, Kunal (Haryana) and Datrana (Gujarat).
- Forerunners of the script: extensive graffiti on pottery and a few seals with geometric and simple animal motifs at Harappa, Rehman Dheri and Kunal anticipate the inscribed seals and Sindhu lipi of the mature civilisation.
- Agriculture and water: the Kalibangan ploughed field (Early Harappan) shows two sets of furrows at right angles — double cropping, like today's rabi–kharif ("a tradition nearly 5,000 years old"); while the Sumerians built canals, Early Harappans in the Baluchistan foothills built gabarbands — check dams across small streams for irrigation.
- It was this technological advancement and economic integration that produced the urban centres of the Harappan civilisation by 2600 BCE — where this note hands over to the harappan-civilisation topic. (The village-to-town mechanics: exchanging villages, networks of communication, some growing into towns — Class 6, Ch 4 "Timeline and Sources of History".)
8. Chronological scaffold and takeaways
| Date | Milestone |
|---|---|
| c. 3.3 mya | earliest stone tools — hominins as tool makers |
| c. 2 mya | Homo erectus exits Africa; oldest settlement in the Indian subcontinent |
| c. 1.5–1.7 mya / 1.2 mya | Attirampakkam (TN) / Isampur (Karnataka) |
| c. 300,000 ya | Homo sapiens evolves in Africa |
| c. 125,000 ya | major sapiens exit from Africa |
| 50,000–12,000 ya | sapiens reach Australia and the Americas |
| c. 40,000 ya | last Neanderthals (Europe/SW Asia) |
| c. 12,000 ya | Ice Age ends — Mesolithic, first population explosion |
| c. 7000 BCE | Mehrgarh — earliest agricultural village |
| 7000–5500 BCE | Pre-Harappan phase claimed at Bhirrana/Kunal (chapter's dating) |
| c. 4000 BCE | first copper — Chalcolithic; regional pottery styles |
| c. 3500 BCE | basis of the Bronze Age Sindhu–Sarasvatī civilisation |
| c. 2500 BCE | Neolithic communities across most of the subcontinent; Early Harappan styles standardise |
| c. 2600 BCE | Mature Harappan urban phase begins (First Urbanisation) |
- The before/after-writing contrast (Class 9, Ch 4 "Early Humans"): more than 99% of human history is preliterate — reconstructed only from artefacts, with approximate dates; writing (from ~5,000 years ago elsewhere; undeciphered Sindhu lipi here) is what turns prehistory into history.
- Method takeaway: everything above rests on tools, fossils and experimental archaeology (archaeologists replicate and use ancient tools to understand them) — prehistory is archaeology's domain end to end.
Exam angles
Prelims:
- Hominin–tool–region matches: habilis — choppers — Olduvai Gorge (Tanzania/Kenya) · erectus — handaxes & cleavers — East African Rift, first out of Africa (~2 mya) · Neanderthal — flake tools — Europe/SW Asia till 40,000 ya · sapiens — blades/microblades, beads, art — Africa 300,000 ya, exit 125,000 ya. Trap: "Homo sapiens was the first to leave Africa" — FALSE (erectus).
- Site–state–period pairings (also map questions): Attirampakkam (TN, Lower Palaeolithic, 1.5–1.7 mya) · Isampur (Karnataka, 1.2 mya) · Bhimbetka (MP, Mesolithic rock art, World Heritage Site) · Mehrgarh (Bolan river, Pakistan — Neolithic c. 7000 BCE) · Sanganakallu (Karnataka, c. 2000 BCE) · Bhirrana & Kunal (Haryana, Pre-Harappan claims 7000–5500 BCE) · Rehman Dheri (early seals/graffiti) · Datrana (Gujarat, beads) · Kalibangan (ploughed field, double cropping).
- Sequence MCQs: Palaeolithic → Mesolithic → Neolithic → Chalcolithic → Bronze Age; diagnostics — microliths + fishing = Mesolithic; domestication + pottery + villages = Neolithic; copper alongside stone = Chalcolithic.
- Mehrgarh specifics: wheat/barley, sheep-goat-zebu, sun-dried brick houses and granaries, grave burials, lapis lazuli-carnelian-shell ornaments, first copper objects.
- Terms: hominin, fossil, australopithecine, Quaternary Period (2.6 million years), Old World, extra-corporal limbs, microlith, burin, Neolithic Revolution, gabarband.
- Number hooks: tools 3.3 mya · Quaternary 26 lakh years · Ice Age end 12,000 ya · >99% of history preliterate · first population explosion = Mesolithic.
Mains:
- The Neolithic Revolution as the hinge of human history — domestication, surplus, sedentism, chieftains and collective welfare → villages → towns; argue "revolution in consequence, gradual in process."
- Climate–human interplay: Ice Age's end driving the Mesolithic resource boom and population explosion; river-bank settlement for water and fertile soil; environment as both opportunity and constraint.
- The continuity thesis in the new NCERT: Mehrgarh (7000 BCE) → Chalcolithic (4000 BCE) → Early Harappan → Mature Harappan (2600 BCE) as unbroken indigenous development — link to First Urbanisation debates, flagging the Sarasvatī-belt early dates as the chapter's claim.
- How prehistory is reconstructed without writing — discarded tools, fossils, stratified sites, experimental archaeology, rock art — and why all its dates are approximate (ties into the sources-and-historiography note).
- Caution against projecting present social assumptions (e.g. gendered division of labour) onto prehistoric evidence.
