World History · Era— ~10,000 BCE — 3,000 BCE —

Before the writing.

From the last Ice Age through the Neolithic Revolution. Hunter-gatherers, the domestication of plants and animals, and the first permanent settlements that would eventually become cities.

What you need to know

When the last Ice Age ended around 10,000 BCE, the world warmed and the megafauna disappeared. Hunter-gatherer bands that had ranged for millennia began to settle. In the Fertile Crescent, the Yangtze valley, Mesoamerica, and the Andes — independently, within a few thousand years of each other — humans figured out how to domesticate plants and animals. The Neolithic Revolution didn’t just feed more people; it built villages, surplus, hierarchy, property, disease, and the social architecture every civilization since has been variations on.
