The controlled fire Hearths in Wonderwerk Cave show humans cooked, warmed, and gathered around flame — the first tool that wasn't held in the hand.
Humans
c. 1M BCE
Mastery of fire Hearths in southern Africa show repeated, controlled use of fire. Cooking shrinks the gut, frees energy for the brain, and turns night into a place where a group can gather.

Cave hand stencils In Sulawesi and El Castillo, humans pressed pigment around their hands. The first signature: I was here.
Humans
c. 40,000 BCE
First cave art In caves from Sulawesi to El Castillo, humans press red ochre handprints and paint animals on stone. Mind made visible — a record kept outside the body for the first time.
Humans
c. 40,000 BCE
First marks on cave walls In Sulawesi and El Castillo, hands and animals stencilled in ochre. Not yet writing — but the impulse to leave a sign that outlasts the body.
Humans
c. 40,000 BCE
First use of native gold Hunter-gatherers in the Levant pick up shining nuggets from streambeds and beat them into ornaments. Gold — soft, untarnishing, dense — becomes the first metal humans treasure.
Humans
c. 40,000 BCE
Carved bone pendants In Europe and Africa, bone, ivory and tooth become wearable. Ornament begins to mark identity, status, belonging.
Humans

Neolithic Revolution Agriculture begins independently in several regions — the New Stone Age transforms human life.
Humans
c. 10,000 BCE
Agriculture begins In the Fertile Crescent, the Yangtze valley and the Andes, people start saving seed and tending herds. Surplus replaces the daily hunt — and with it comes property, hierarchy and time you can plan.
Civilisation
c. 9000 BCE
Barter begins Earliest known exchange of goods between communities — obsidian, salt, shells.
Humans
c. 9000 BCE
Cold-hammered copper In the highlands of Anatolia and Iran, people learn that native copper can be pounded into hooks, beads and small blades without fire. The Stone Age begins to give way.
Humans
9,000 BCE
Agriculture We stop chasing food and start growing it. Towns become possible.
Civilisation
c. 8000 BCE
Vegetable tanning begins Bark, leaves and oak galls are used to stop hide from rotting. Leather, properly so-called, exists.
Humans
c. 8000 BCE
Counting tokens of clay Across the Near East, small clay shapes track sheep, jars of oil, measures of grain. Trade demands memory — and memory needs a thing to hold it.
Humans
c. 7000 BCE
First cities rise Çatalhöyük, Jericho, Uruk: thousands of strangers learn to live within shouting distance. Streets, granaries, shared walls — the city becomes humanity's longest-running experiment.
Civilisation
5000 BCE
Copper Age (Chalcolithic) Humans begin smelting copper — the first metal age, bridging stone and bronze.
Humans
c. 5000 BCE
Smelting copper from ore Furnaces in the Balkans and Anatolia hot enough to free copper from rock — the first time humans extract a metal from stone. Mining and metallurgy are born together.
Civilisation
c. 4500 BCE
Sumer rises in Mesopotamia Between the Tigris and Euphrates, the first cities grow walls. Uruk, Ur, Eridu — temples, ledgers, kings. The world learns the shape of urban life.
Civilisation
c. 4,500 BCE
Gold enters the story The Varna Necropolis in Bulgaria yields the oldest worked gold ever found — buried with a chieftain who never imagined it would still glow 6,500 years later.
Civilisation
c. 3500 BCE
The wheel Mesopotamian potters spun the first wheels; only later did anyone think to put one under a cart. Most great inventions are first used for the wrong thing.
Civilisation
c. 3500 BCE
The wheel Potters spin clay; later, carts roll. The wheel collapses distance and changes what one person can move in a day.
Civilisation
c. 3500 BCE
The wheel Somewhere on the Eurasian steppe, potters' wheels become cart wheels. Goods, armies, and ideas suddenly roll faster than they walk.
Civilisation
c. 3500 BCE
Time becomes a concept worth tracking Sumerian and Egyptian civilisations begin organising life around the sun and the seasons. Time is no longer just felt — it is counted, named, and shared.
Measuring Time
c. 3500 BCE
The horse, broken to ride On the Pontic steppe, people climb onto a horse's back. Distance shrinks; the steppe peoples become the engines of every continent's history.

Bronze Age begins Tin-copper alloy revolutionises tools, weapons and trade across Eurasia.
Humans
c. 3300 BCE

Age of Writing Sumerian cuneiform marks the beginning of recorded history — prehistory ends.
Humans
3,200 BCE
Writing invented Sumerian cuneiform. Time can now outlive a single life.
Civilisation
c. 3200 BCE
Writing is invented Sumerian scribes press cuneiform into clay to track grain and debt. Memory escapes the head — laws, stories and contracts can now outlive the people who made them.
Civilisation
c. 3200 BCE
Cuneiform on wet clay In Sumer, a reed pressed into clay becomes the first true writing. The earliest tablets are not poems — they are receipts.
Civilisation
c. 3100 BCE
Egypt unites along the Nile Upper and Lower Egypt become one kingdom. A civilization built on the river's rhythm — flood, plant, harvest — that will endure three thousand years.
Civilisation
c. 3100 BCE
Egyptian hieroglyphs On temple walls and papyrus, a script that is at once picture, sound, and idea. It will be read by priests for three millennia, then forgotten.
Civilisation

Mesopotamian markets Cities like Ur develop dedicated trading districts and weighed-silver pricing.
Civilisation
c. 3000 BCE
Sumerians count in sixties A base-60 system invented for trade still shapes our minutes, seconds and degrees.
Civilisation
c. 3000 BCE
The plough Oxen-drawn ploughs in the Fertile Crescent turned soil deep enough to feed cities. Agriculture stops being gardening and becomes industry.
Civilisation
c. 3000 BCE
The plough breaks the soil Ox-drawn ploughs turn heavy soils that hand tools could not. Yields rise, populations grow, and the village becomes the kingdom.
Civilisation
c. 2,600 BCE
Mesopotamia: jewellery as written language In the city-states of Sumer and later Babylon, gold leaf, lapis lazuli, and carnelian were stitched into headdresses and pectorals for queens and priests. Jewellery wasn't decoration — it was rank, contract, and prayer carried on the body.
Civilisation
c. 2600 BCE
The Standard of Ur A wooden box inlaid with shell and lapis depicting a Sumerian battle and feast. War on one side, peace on the other — already.
Civilisation
c. 2600 BCE
Indus Valley cities Harappa and Mohenjo-daro lay grids of brick streets, drains beneath them. A civilization of planners, traders, and a script we still cannot read.
Civilisation
2,560 BCE
Pyramids of Giza A 4,500-year-old answer to "what will outlast us?"
Civilisation
c. 2,500 BCE
The Indus Valley: the bead workshops of Harappa Long before written history, craftspeople at Harappa and Mohenjo-daro were drilling micro-perforations through hard carnelian beads with techniques Europe wouldn't match for three thousand years. They traded those beads from the Persian Gulf to Mesopotamia.
Civilisation
c. 2500 BCE
Goldsmithing in Mesopotamia and Egypt Royal workshops master granulation, soldering and lost-wax casting. Gold becomes the metal of gods and kings — and the first portable store of value.

Shadow clocks in Egypt Ancient Egyptians divide daylight into twelve parts using simple shadow-casting sticks and stepped stone gnomons — the first deliberate measurement of the passing day.
Civilisation
c. 1,500 BCE
Egyptian goldsmiths perfect the craft Granulation, cloisonné, lost-wax casting. Pharaohs are buried in jewellery so finely made we still copy the techniques today.

Water clocks (clepsydra) Babylonians and Egyptians measure time by flowing water.
Civilisation
c. 1400 BCE
Water clocks (clepsydra) Mesopotamian and Egyptian craftsmen perfect vessels that drip water at a steady rate, marking hours by the falling level. Time becomes something a household can keep, not just a king.
Civilisation
c. 1400 BCE
Water clocks (clepsydra) Babylonians, Egyptians, and later the Greeks develop water clocks that work day and night, in any weather. The first mechanism that does not need the sun.

Iron Age begins Iron smelting spreads after the Bronze Age Collapse — harder, cheaper, more democratic metal.
Humans
c. 1,200 BCE
Phoenicia: jewellery as global trade Phoenician traders carried gold, glass, and amber from one end of the Mediterranean to the other, mixing Egyptian, Greek, and Near Eastern motifs in a single piece. They were the first culture to make jewellery designed to travel.
Civilisation
c. 1200 BCE
Bronze, then iron Smiths learn to alloy copper and tin, then to smelt iron. Better tools, better weapons, and a new class of specialists who answer to no field.

Chinese script begins Marks scratched on tortoise shells to ask the gods. Three thousand years later, a Beijing schoolchild can still recognise the oldest characters.
Civilisation
c. 1200 BCE
The Iron Age Hittite smiths learn to smelt iron from oxide ores at higher temperatures. Iron is everywhere copper is not — and once people learn to work it, bronze elites lose their edge.

The Etruscans: granulation so fine the secret was lost Etruscan goldsmiths in central Italy produced granulation so fine — sometimes 200 grains per square millimetre — that the technique was considered lost until the 19th century. Their work set the bar that Renaissance Europe later spent centuries trying to recover.
