The Emergence and Evolution of Humankind

The Emergence and Evolution of Humankind (Millions of Years Ago – Approximately 2.5 Million Years Ago)

• Hominids: Hominids, the first members of the human lineage, emerged in Africa approximately 6-7 million years ago. The ability to walk on two legs (bipedalism) was one of the most significant steps in this evolution.
• Australopithecus: Emerging approximately 4 million years ago, this genus includes species with the first definitive evidence of walking on two legs.
• Homo Habilis (“Handy Man”): Considered the first species to make stone tools, emerging around 2.5 million years ago. Their brain size was larger than that of Australopithecus.

The Stone Age (Paleolithic, Mesolithic, Neolithic)

a. Paleolithic Age (Old Stone Age – Approx. 2.5 Million Years Ago – 10,000 BCE)

• Homo Erectus (“Upright Man”): Emerged approximately 1.8 million years ago. They were the first human species to successfully control fire. They are considered the first hominid species to migrate out of Africa.
• Homo Neanderthalensis (Neanderthals): Lived in Europe and Asia about 400,000 years ago. They were adapted to cold climates, used complex tools, and buried their dead.
• Homo Sapiens (“Wise Man”): Emerged in Africa about 300,000 years ago. They are the direct ancestor of modern humans. They stood out for their language ability, complex thought structure, and works of art (cave paintings). They subsisted by hunting and gathering. They had a nomadic lifestyle.

b. Mesolithic Age (Middle Stone Age – Approx. 10,000 BCE – 8,000 BCE)

• The climate became milder with the end of the Ice Age.
• Smaller and sharper stone tools called **microliths** were developed.
• Hunting techniques, such as the bow and arrow, improved.

c. Neolithic Age (New Stone Age – Approx. 8,000 BCE – 4,000 BCE)

• Neolithic Revolution: A turning point in human history. Characterized by the beginning of agriculture (planting crops) and the development of animal husbandry (domestication of animals).
• Settled Life: Agriculture and animal husbandry led humans to abandon their nomadic lifestyle and establish permanent settlements (villages, first cities).
• Population Increase: The population increased due to the regularity of food sources.
• New Technologies: New technologies emerged, such as polished stone tools, ceramic (pottery) making, and weaving.
• Social Structure: The concept of private property and the division of labor began to develop.

The Metal Age (4,000 BCE – 1,200 BCE)

a. Copper Age (Chalcolithic Age – Approx. 5,000 BCE – 3,000 BCE)

• The first period when humans learned to process metals. Copper was the first metal used because it was easily worked.
• Copper tools began to be used alongside stone tools.

b. Bronze Age (Approx. 3,000 BCE – 1,200 BCE)

• Bronze, a harder and more durable alloy obtained by mixing copper and tin, became widespread.
• Weapons and tools became more effective.
• Large states, city-states, and empires were established (Mesopotamia, Egypt).
• The Invention of Writing (Approx. 3200 BCE): The invention of cuneiform writing by the Sumerians in Mesopotamia ended the Prehistoric Ages and began the **Historical Ages**.

c. Iron Age (1,200 BCE – Continuing Impacts to the Present Day)

• The processing and use of iron were learned. Since iron was more abundant and harder than bronze, it revolutionized tool and weapon production.
• Large iron tools increased agricultural productivity.
• Great armies and empires (Hittites, Assyrians, Persians) grew stronger.

First Civilizations and Ancient Ages (Approx. 3,500 BCE – 500 CE)

• Mesopotamia: Sumerians, Akkadians, Babylonians, Assyrians. First cities, writing, legal codes (Hammurabi’s Code), astronomy, mathematics.
• Egypt: Pharaohs, pyramids, hieroglyphic writing, medicine, engineering.
• Indus Valley: Harappa, Mohenjo-Daro. Urban planning, sewage systems.
• China: Dynasties, the Silk Road, Confucianism, Taoism, paper, gunpowder.
• Greek Civilization: Democracy, philosophy, science, art, architecture, literature, the Olympics.
• Roman Empire: Law, engineering (roads, aqueducts), military discipline, vast empire.

Middle Ages (500 CE – 1500 CE)

• Began with the collapse of the Western Roman Empire.
• Feudal system in Europe, strong influence of the church.
• Rise of Islamic Civilization: Great progress in science, medicine, mathematics, philosophy, art, and literature. The Golden Age.
• Tang and Song Dynasties in China.
• Crusades, Mongol Invasions.

Early Modern Age (1500 CE – 1800 CE)

• Renaissance: Rebirth in art, science, and philosophy in Europe.
• Reformation: Religious reform movements.
• Age of Exploration: Discovery of new continents (America), expansion of world trade.
• Scientific Revolution: Development of scientific thought and methods (Copernicus, Galileo, Newton).
• Age of Enlightenment: Philosophical movement prioritizing rationalism and individual liberties.
• Rise of absolute monarchies and the foundations of nation-states.

Contemporary Age (1800 CE – Present Day)

• Industrial Revolution: Steam power, mechanization, factory system, urbanization, social and economic changes.
• French Revolution: Spread of concepts such as nationalism, democracy, and human rights.
• Two World Wars: Major global destruction and political restructuring.
• Cold War: Bipolar world led by the USA and the USSR.
• Information Age and Globalization: Development of computers, the internet, communication technologies, worldwide interaction, and interdependence.
• Rapid technological developments (space exploration, artificial intelligence, biotechnology).
• Environmental issues, demographic changes, global inequalities.

Human history is a process of continuous change and development. Each era built upon the accumulation of the previous one and set the stage for the next.
