Prehistory

Long ago, people lived without writing.

They used tools made of stone. These tools helped them work.

Some people used fire. Fire kept them warm. It also helped them cook food.

People moved from place to place. They looked for food to eat. They lived in small groups.

Later, people made tools from metal. They used bronze and iron. This changed how they lived.

We learn about them from old things. We find tools and bones in the ground. It is a big puzzle!

Prehistory is the time before people used writing.

We do not have books from this time. Instead, we study old things found in the ground. These items are called artifacts.

Experts like archaeologists study these tools and bones. They use science to learn how people lived.

Much of prehistory is called the Stone Age. This lasted for a very long time. In the early Stone Age, people made tools from stone. Some people learned to use fire. Fire helped them cook food and stay warm.

Many people lived as hunter-gatherers. They moved often to find food. Later, some people made small tools from flint. They even made wooden boats and bows.

Prehistory ended when writing began. This happened at different times in different places. In Egypt, writing started a long time ago. In other places, it started much later. After the Stone Age, people used metal. They made tools from bronze and iron. This changed the world forever.

Prehistory is the long period of time before humans began using writing.

Because there are no written records, we call this era anonymous. We cannot read the names of leaders or nations from this time. Instead, we learn about the past through material things left behind. These items include stone tools, bones, and other artifacts.

By studying these remains, we can piece together how early people lived. It is like solving a giant puzzle without an instruction manual.

Scientists use many different tools to study this era. Archaeologists dig into the earth to find objects in their original places. They work with other experts like biologists and geologists to understand the environment.

One very important step is dating the finds to see how old they are. Many researchers use a method called radiocarbon dating to find out the age of organic materials. Other experts study DNA in bones to see how people were related. This mix of science helps us see a clearer picture of the past.

Prehistory started when human-like beings first appeared on Earth.

The exact start date depends on where you look in the world. In Africa, signs of humans appear around 2.5 million years ago. In Europe, the first signs are found around 1.3 million years ago. The end of prehistory happened when writing was invented. This did not happen everywhere at once. For example, writing began in Egypt around 3100 BCE. In New Guinea, the prehistoric era ended much later, in the 1870s.

In many parts of the world, people divide prehistory into three ages.

These are the Stone Age, the Bronze Age, and the Iron Age. The Stone Age lasted for a huge amount of time. It covers about 99% of all human history. Within the Stone Age, there was the Palaeolithic, or Old Stone Age. During this time, early humans used stone tools and learned to control fire.

Later came the Mesolithic, which was a middle period between stone and farming.

These ancient changes connect to the world we know today. The way people moved and found food shaped how societies grew. Some groups lived as nomadic hunter-gatherers who moved to find food. Others eventually stayed in one place to start farming.

This shift led to the first big civilizations in places like Mesopotamia and Egypt. These cultures were among the first to develop writing. Once they wrote things down, they moved from prehistory into recorded history.

Prehistory is the vast era of human existence before the invention of writing systems.

Because there are no written records, this period is often described as anonymous. We cannot read the names of specific leaders or nations from this time. Instead, researchers must study the activities of archaeological cultures. This means they look at material processes, remains, and artifacts. The term "prehistory" is sometimes called pre-literary history. It marks the time between the first stone tools and the start of recorded history. The first writing systems appeared roughly 5,200 years ago. However, the transition from prehistory to history happened at different times globally.

Because writing spread slowly, the end of prehistory varies by region. When a culture is written about by others but lacks its own writing, it is called protohistory. This distinction is vital for archaeologists. They use modern labels like "Neanderthal" or "Iron Age" to organize their findings. These labels are sometimes debated by scholars. Still, they are necessary for conveying information about prehistoric peoples. Without these names, it would be difficult to distinguish between different groups. Prehistory is defined by what we can touch and find in the earth.

To understand this era, scientists use many different disciplines. Archaeologists and physical anthropologists are the primary researchers. They use excavation and geographic surveys to interpret the behavior of non-literate peoples. They often work alongside natural scientists to find answers. For example, biologists and geologists provide context about the ancient environment. Human population geneticists and historical linguists also offer valuable insights. Even paleontology and molecular genetics help reveal the past. These experts study how objects and ideas passed among prehistoric people.

A key step in this research is dating the evidence. Scientists use many reliable techniques to determine how old an object is. One common method is radiocarbon dating. This technique helps find the age of organic materials. Other researchers use forensic chemical analysis to find the origin of materials. Genetic analysis of bones can reveal kinship and physical traits. Some experts even reconstruct ancient spoken languages to understand how people communicated. These scientific tools allow us to build a timeline of human development.

In Eurasia, historians often use the three-age system to divide prehistory. This system names periods based on predominant tool-making technologies. The three stages are the Stone Age, the Bronze Age, and the Iron Age. Some areas also include the Chalcolithic, or Copper Age, between the Stone and Bronze Ages. The Stone Age was incredibly long, covering about 99% of human history. It lasted roughly 3.4 million years. It ended between 4000 BCE and 2000 BCE when metalworking began. This system is used widely in Eurasia and North Africa.

The Stone Age is further divided into several important stages. The Palaeolithic, or Old Stone Age, began with the first stone tools. These tools date back about 3.3 million years to sites in Kenya. During the Lower Palaeolithic, early hominins began using stone implements. Later, during the Middle Palaeolithic, evidence shows humans used fire. Fire allowed people to cook, stay warm, and provide light. The Upper Paleolithic saw the rise of organized settlements and art.

Following this was the Mesolithic, or Middle Stone Age. This period occurred after glaciers retreated about 10,000 years ago. It was a time of transition before the rise of agriculture.

Prehistoric timelines vary greatly depending on the location. In Africa, human presence is dated to about 2.5 million years ago. In Asia, it is dated to about 1.8 million years ago. In Europe, signs of humans appear around 1.3 million years ago. The end of prehistory also depends on when writing was adopted locally. In Egypt, prehistory ended around 3100 BCE. In New Guinea, it ended much more recently in the 1870s. In Australia, the end of prehistory is often marked by the year 1788. These differences show that human progress did not happen at the same speed everywhere.
