• Explain the agricultural revolution.
• Understand the concept of civilization.
• Describe early civilizations in the Middle East, India, and China.

Human Evolution and Migration

• All modern humans trace ancestry back to Africa.
• Modern humans emerged between 100,000 and 300,000 years ago in Central Africa.
• Evolutionary divergence from chimpanzees occurred around 7 million years ago.
• Various hominid species (e.g., Australopithecus, Homo habilis, Homo erectus) existed.
• Homo erectus was the first to leave Africa.
• Modern humans left Africa around 80,000 years ago.
• Migration spread to Asia, Australia, Europe, and the Americas.
• Interaction and a little interbreeding with Neanderthals.

Hunter-Gatherer Societies

• For 90% of history, humans were hunter-gatherers.
• Societies were small, mobile, and focused on survival.
• Evidence of culture included cave paintings and burial practices.

Agricultural Revolution

• Occurred between 10,000 and 12,000 years ago.
• Domestication of plants and animals led to settled societies.
• First farming evidence from the Fertile Crescent (Mesopotamia).
• Farming led to the rise of cities and complex societies.

Early Civilizations

Mesopotamia (Fertile Crescent)

• Location: Between Tigris and Euphrates Rivers.
• Early societies: Sumerians, Akkadians, Babylonians, Assyrians, Persians.
• Innovations: Writing (e.g., Epic of Gilgamesh), mathematics, legal codes (Hammurabi's Code).
• Cultural continuity through successive civilizations.

Ancient Egypt

• Location: Along the Nile River.
• Unified Kingdom by 3200 BCE.
• Known for architecture (e.g., Pyramids) and art.
• Pharaohs viewed as gods.
• Fertile Nile valley allowed for thriving agriculture.

Indus Valley Civilization (Harappan)

• Location: Indus River, modern-day India/Pakistan.
• Established farming communities by 7,000 BCE.
• Cities: Harappa, Mohenjo-daro.
• Developed trade networks with Mesopotamia.
• Declined around 1900 BCE due to unknown reasons.
• Arrival of Aryans, leading to Vedic culture.

Early China

• Location: Yellow River Valley.
• Farming communities by 7,000 BCE.
• Early dynasties: Xia, Shang.
• Developed bronze tools and weapons.
• Distinctive writing system using characters for words.

Conclusion

• Civilizations developed near rivers, benefiting from fertile lands.
• Agriculture was crucial in transforming human societies from hunter-gatherers to complex civilizations.
