Chapter 4 — Early Humans and Beginning of Civilisation (Notes · History)

This chapter traces human history from our earliest ancestors through the Stone Ages to the first Bronze Age civilisations. The period before writing is called prehistory and is known mainly through archaeological evidence (tools, fossils, cave art).

The Big Questions

How did humans live before civilisation? How did they communicate before writing? How is archaeology helpful? How did early civilisations interact?

Before and After Writing

More than 99% of human history (≈3 million–5,000 years ago) is prehistory — reconstructed from artefacts, with only approximate dating. The last 5,000 years (less than 1%) is the historical period — reconstructed from written documents plus material remains, with relatively accurate dating. Early scripts: the Harappan (Sindhu lipi, pictographic, not yet deciphered), Sumerian cuneiform and Egyptian hieroglyphs (both deciphered, ~5,000 years ago). In India, the Brahmi script (from ~400 BCE) was formalised under Emperor Aśhoka.

Evolution & Human Ancestors

Biological evolution: gradual physical/genetic change from early ancestors (australopithecines) to modern Homo sapiens. Cultural evolution: how humans adapted (tools, technology) during the Quaternary Period. Humans evolved in Africa and migrated out. Ancestors: Homo habilis (‘handy man’, Olduvai Gorge, chopper tools) → Homo erectus (upright; handaxes & cleavers; first to leave Africa ~2 million yrs ago) → Homo neanderthalensis (Europe/SW Asia, flake tools) → Homo sapiens (evolved in Africa ~300,000 yrs ago; only human species alive today; developed complex technology). Tool-makers are called hominins; tools are ‘extra-corporal limbs’. Remains that turned to stone over ages are fossils.

Periods of Early Human History

• Palaeolithic (Old Stone Age) — hunting–gathering; simple stone tools.
• Mesolithic — microlithic (tiny) tools; transition between hunting-gathering and farming.
• Neolithic (New Stone Age) — shift to agriculture & settled life; domestication of animals; polished stone tools (the Neolithic Revolution).
• Chalcolithic (Copper-Stone Age) — copper + stone tools; early metallurgy.
• Bronze Age — bronze (copper + tin); trade, towns, early civilisations.
• Iron Age — iron metallurgy; stronger tools/weapons; more advanced societies.

Palaeolithic & Mesolithic in India

Oldest Indian settlements ~2 million yrs ago — Attirampakkam (Tamil Nadu, 1.5–1.7 m yrs), Isampur (Karnataka, 1.2 m yrs); handaxes, cleavers, scrapers, choppers (quartzite/limestone). Later: bow & arrow, blades/microblades, cave paintings and body pigments, beads. ~12,000 yrs ago the climate warmed (Mesolithic): a population boom, microlithic tools, fishing, and flourishing art — e.g., the World Heritage rock shelters of Bhimbetka (Madhya Pradesh).

The Neolithic Revolution & Sindhu–Sarasvatī roots

Gradual shift to a food-producing life: domestication of plants & animals, pottery, and the first villages (did NOT happen everywhere at the same time). In India, Mehrgarh (Bolan River, ~7000 BCE) is the oldest Neolithic/agricultural village — mud-brick houses, granaries, wheat/barley, sheep/goats/zebu cattle, and the first copper objects (Chalcolithic by ~4000 BCE). This led to the Bronze Age Sindhu–Sarasvatī (Harappan) civilisation (~3500/2600 BCE). Early Harappan features — pottery, beads, shell bangles, copper working, perimeter walls, seals, early script. (Kalibangan shows ploughed fields with cross-furrows — early double-cropping; Harappans used standard binary weights 1,2,4,8,16…)

Bronze Age Civilisations Outside India

Four early civilisations grew in river plains: Harappan (Sindhu–Sarasvatī), Mesopotamian (Euphrates–Tigris), Egyptian (Nile), Chinese (Huang He). Mesopotamia & the Indus were close, enabling trade; Egypt & China had little direct contact with India.

• Mesopotamia (‘land in between’, the Fertile Crescent): earliest city-based civilisation. Four city-states — Sumerian (first cities at Ur; canals & mud/burnt bricks; ziggurat temples; invented cuneiform writing ~3200 BCE, the wheel, sailboat, and the base-60 number system → 60-min hour, 360° circle), Akkadian (Sargon; world’s first dynastic empire; traded with Meluhha = the Harappans), Assyrian, and Babylonian (Hammurabi’s famous Code of Hammurabi law code).
• Egypt (Nile valley; land called Kemet): annual Nile floods left fertile mud; rulers were Pharaohs; pyramids (e.g., Step Pyramid at Saqqara) and mummification (belief in the ka); hieroglyphic script and papyrus; script deciphered via the Rosetta Stone (Champollion, 1822).
• China (Huang He & Yangtze): Shang & Zhou (Bronze Age) then Qin & Han (Iron Age); oracle bones (earliest records), logographic script, jade & bronze craft, the Great Wall, silk (→ the Silk Route), first paper currency and civil-service exams.

Before we move on: Prehistory is studied through archaeology; humans evolved in Africa and spread worldwide; the Palaeolithic→Mesolithic→Neolithic→Chalcolithic→Bronze→Iron sequence tracks technological progress; the Neolithic Revolution brought farming and villages; and Bronze Age civilisations (Harappan, Mesopotamian, Egyptian, Chinese) arose independently in fertile river valleys, developing writing, cities, trade and administration.

Key Terms

Hominin = modern humans + early human-like ancestors (tool makers); Fossil = preserved stone remains of past life; Old World = oldest human settlements of Africa/Asia/Europe; City-state = a sovereign state centred on a city; Cuneiform = Sumerian wedge-shaped writing on clay; Ziggurat = stepped temple-tower; Papyrus = Egyptian paper; Mummification = preserving the body for afterlife; Meluhha = Mesopotamian name for the Harappan region.
