8 steps · 7 domains · 301,474 years

Food Triagesince the species began · 300,000 BCThe hard-won knowledge of what is safe to eat and how cooking turns poison into food — the difference between a full belly and a fatal mistake.
qui l'exigeait — l'a rendue fabricable ↑
Control of Fire~1,000,000 BC · 1,000,000 BCThe ability to keep, feed, and eventually start a fire at will — humanity's first external source of energy.
l'a rendue fabricable ↓
Charcoalby ~4,000 BC (as furnace fuel) · 4,000 BCWood baked without air until only nearly-pure carbon remains — a fuel that burns far hotter and cleaner than the wood it came from.
l'a rendue possible ↓
Iron Smelting (Bloomery)~1,500 BC · 1,500 BCReducing iron ore to workable metal in a charcoal-fired clay furnace.
l'a rendue possible ↓
Navigation~1090 AD (magnetized needle described 1088; compass at sea by ~1119) · 1090 ADThe compass, the chart, and the stars — the toolkit that lets a ship leave sight of land and arrive somewhere on purpose.
qui l'exigeait — l'a rendue pensable ↑
Numbers and Geometry~3,400 BC (token accounting) · 3,400 BCWays of counting, calculating, and measuring shapes — the mental tools that turn "some sheep" into "seventeen sheep" and "that field" into "so many paces on each side."
l'a rendue pensable ↓
Writing~3,200 BC · 3,200 BCMarks that store speech and records outside a human head — memory that survives its owner and travels without a messenger.
l'a rendue pensable ↓
A code becomes law only when it is fixed in durable signs; without writing "the rule" is just whatever a ruler remembers, or claims to, today.
Written law codes~1,750 BC (Hammurabi's stele) · 1,750 BCA single, public, comprehensive text that fixes the rules and their penalties in advance — so that justice becomes something you can read and point to instead of whatever the powerful decide on the day.
l'a rendue pensable ↓
The monopoly is worthless unless a written statute defines it in advance and a court will enforce it against infringers alike.
Patents1474 (Venetian Statute) · 1474 ADA time-limited legal monopoly the state grants an inventor in exchange for publishing how the invention works — trading a temporary right to exclude copiers for a permanent addition to the public store of know-how.
