Early Humans and the Beginning of Civilization

Introduction to Human History

• The chapter discusses human history, emphasizing its importance in understanding human evolution and lifestyle changes from living in forests to forming villages and cities.

• Writing was invented around 5000 years ago, marking a division between prehistory (before writing) and history (after writing).

• Historians rely on archaeology to understand prehistoric humans through tools, pottery, burials, and rock paintings due to the lack of written records.

Human Evolution

• Human evolution is influenced by biological changes (genes) and cultural adaptations to environmental changes.

• Early humans like Homo habilis used their brains for tool-making; Homo erectus was the first to walk upright and migrate out of Africa.

• The Out of Africa theory suggests that ancestors spread globally from Africa; modern humans are classified as Homo sapiens.

Chronology of Human History

• Human history is divided based on tool usage rather than exact time periods: Stone Age (using stones), Bronze Age (using bronze), Iron Age (using iron).

• The Paleolithic Age features basic stone tools; Mesolithic Age saw improvements with smaller microlithic tools; Neolithic Age introduced polished tools alongside agriculture.

Lifestyle Changes in Prehistoric Ages

• During the Paleolithic and Mesolithic ages, humans relied on hunting and gathering without settled lifestyles but began using caves for shelter.

• Inventions such as bows and arrows emerged during the Paleolithic age, indicating advancements in hunting techniques.

Neolithic Revolution

• The Neolithic age marked a revolutionary shift with farming practices leading to permanent settlements, surplus food production, and village development.

• This agricultural revolution allowed for domestication of plants and animals, laying foundations for future civilizations.

Indus Valley Civilization

Features of Indus Valley Civilization

• Flourished along rivers in present-day India/Pakistan with common professions centered around agriculture during the Bronze Age.

• Advanced urban planning included brick houses, drainage systems, craft production, trade networks, but their script remains undeciphered.

Mesopotamian Civilization

Overview of Mesopotamia

• Known as "land between two rivers" (Tigris & Euphrates), this civilization thrived in modern Iraq with advanced irrigation systems.

• Sumerians were notable for creating cuneiform script on clay tablets; they made significant contributions like the wheel and mathematical systems based on 60.

Dynasties in Mesopotamia

• Various dynasties ruled including Akkadians under Sargon who engaged in trade with Indus Valley civilization.

• Babylonian King Hammurabi established one of the first written law codes known as Code of Hammurabi which favored wealthier classes over poorer ones.

Egyptian Civilization

Characteristics of Ancient Egypt

• Centered around the Nile River which divided Upper & Lower Egypt; hieroglyphics were developed for record keeping on papyrus.

• Pharaoh held top position within society; pyramids served as tomb structures reflecting beliefs about afterlife.

Cultural Practices

• Mummification preserved bodies for burial while astronomy played a role in agricultural cycles linked to seasonal floods.

Chinese Civilization

Development Along Rivers

• Flourished near Huang He & Yangzi Rivers utilizing logographic scripts where characters represented words or concepts.

Innovations

• Notable advancements included metallurgy skills leading to weaponry/tools creation along with early forms of civil service exams.

Trade & Defense

• Silk invention during Neolithic period led to prosperous trade routes while Great Wall construction aimed at protecting against nomadic tribes' invasions.
