HUMAN ORIGINS & MIGRATION

300,000 - 10,000 BCE

Cradle of Humanity

In the heart of Africa, approximately 300,000 years ago, our species - Homo sapiens - emerged. For hundreds of thousands of years, humans lived as hunter-gatherers, developing tools, language, and culture. Then, around 70,000 years ago, small groups began the greatest journey in history - walking out of Africa to populate every continent on Earth.

Human Evolution

  • Homo sapiens evolves in Africa
  • Brain size increases
  • Language develops
  • Fire mastery (~400,000 YA)

Out of Africa

  • First migration (~70,000 YA)
  • Coastal route to Asia
  • Australia reached (~65,000 YA)
  • Europe populated (~45,000 YA)

Ice Age Survival

  • Last Ice Age (26,000-19,000 YA)
  • Sea levels 120m lower
  • Land bridges form
  • Beringia connects Asia-Americas

Americas Reached

  • Via Beringia (~15,000 YA)
  • Spread through continents
  • South America by 14,000 YA
  • All continents populated

East Africa

Origin of Homo sapiens ~300,000 YA

Europe

First humans arrive ~45,000 YA

Australia

Reached by boat ~65,000 YA

Beringia Land Bridge

Route to Americas ~15,000 YA

South America

Reached ~14,000 YA

Around 10,000 BCE, as the Ice Age ended, humans made a revolutionary discovery - they could plant seeds and grow their own food. This "Agricultural Revolution" began in the Fertile Crescent and spread globally, transforming nomadic hunter-gatherers into settled farmers. Villages grew into towns, populations exploded, and civilization was born.

Domestication

  • Wheat, barley in Fertile Crescent
  • Rice in China (~8,000 BCE)
  • Maize in Mesoamerica
  • Dogs, sheep, goats, cattle

First Settlements

  • Jericho (~9,000 BCE)
  • Çatalhöyük (~7,500 BCE)
  • Permanent mud-brick houses
  • Population growth begins

Agricultural Centers

  • Fertile Crescent (wheat, barley)
  • Yellow River, China (rice, millet)
  • Indus Valley (various crops)
  • Mesoamerica (maize, beans)

Social Changes

  • End of nomadic lifestyle
  • Social hierarchies emerge
  • Surplus food = specialization
  • Trade networks develop

Fertile Crescent

Wheat, barley domesticated ~10,000 BCE

Yellow River, China

Rice, millet ~8,000 BCE

Mesoamerica

Maize, beans, squash ~7,000 BCE

Indus Valley

Various crops ~7,000 BCE

BRONZE AGE

3,300 - 1,200 BCE

👑

The discovery of bronze - an alloy of copper and tin - revolutionized human society. Stronger than stone, bronze enabled better tools, weapons, and art. This technological leap fueled the rise of the first great civilizations: Mesopotamia, Egypt, the Indus Valley, and China. Writing was invented, cities grew, and empires emerged.

Metallurgy

  • Copper + tin = bronze
  • Stronger tools & weapons
  • Casting techniques develop
  • Tin trade routes emerge

First Cities

  • Uruk, Ur in Mesopotamia
  • Memphis, Thebes in Egypt
  • Mohenjo-daro, Harappa
  • Anyang in China

Writing Invented

  • Cuneiform (Sumer, 3400 BCE)
  • Hieroglyphics (Egypt, 3200 BCE)
  • Indus script (2600 BCE)
  • Chinese oracle bones (1200 BCE)

Civilizations Rise

  • Sumer, Akkad, Babylon
  • Egyptian Old Kingdom
  • Indus Valley cities
  • Shang Dynasty China

Mesopotamia

Sumer, Akkad, Babylon | ~3500 BCE

Ancient Egypt

Old Kingdom begins ~3100 BCE

Indus Valley

Harappa, Mohenjo-daro | ~2600 BCE

Shang China

Bronze casting masters | ~1600 BCE
