The story of human beings and their societies is a story of slow change. It took an immense span of time. The first upright hominids lived on the African savanna. Today we live in dense, connected societies. Along the way, humans changed both themselves and the way they live together.
This unit follows that journey. First, it looks at how our species emerged biologically. Next, it studies the slow growth of human society from the Stone Age. Then it looks at the big change brought by farming. After that, it covers the rise of industry and capitalism. Finally, it describes social behaviour in the present world.
The biological origin of human beings is explained by the theory of evolution. Charles Darwin explained it most clearly through his idea of natural selection. According to this idea, living species change slowly over many generations. Some individuals have traits that suit their environment better. These individuals are more likely to survive and have young. They pass their traits on to their offspring.
Human beings did not appear suddenly in their present form. They came through a long line of ancestors. These ancestors are called hominids.
Australopithecus was one of the early hominids. It was an ape-like creature. It could walk upright on two legs. This is called bipedalism. But its brain was still small.
Later came members of our own genus, Homo. One of them was Homo erectus. This ancestor used fire and simple tools. It also spread out of Africa into Asia and Europe.
Finally came Homo sapiens, the modern human species. Homo sapiens has a larger brain. It has complex language. It can think in abstract ways and create art and culture. Scientists widely accept that modern humans first came from Africa. Over tens of thousands of years, they moved across the world.
A simple example helps here. A potter does not shape clay in one stroke. The potter presses the clay many times in small ways. In the same way, evolution shaped the human body and brain through countless small changes. This took a very long time.
Historians and scientists need evidence to tell this story. They use fossils and stone tools found at many sites around the world.
Human society began in the Stone Age. The name comes from the stone tools that early people made and used. This period has three phases. They are the Paleolithic (Old Stone Age), the Mesolithic (Middle Stone Age) and the Neolithic (New Stone Age).
In the Paleolithic phase, people were hunters and gatherers. They lived in small bands. They moved from place to place to find wild animals and plants. They had no permanent homes. They depended fully on nature. Slowly, their lives improved. They discovered fire and made sharper tools.
In the Mesolithic phase, tools became smaller and finer. People began to fish. They also used a wider range of foods.
The Neolithic phase brought the biggest change. People learned to grow crops. They also learned to tame animals. This let them settle in one place. Settled life led to villages. It also led to the division of labour, pottery, weaving and the first trade. Society became more organized. There were families and clans. There were also rules for living together.
Nepal shows the same movement. Early settlement patterns in its valleys and river plains moved from wandering groups toward settled farming communities.
The agricultural age began when humans changed how they got food. Before, they hunted and gathered. Now they deliberately grew crops and raised domesticated animals. This change is sometimes called the Agricultural Revolution. It was one of the most important turning points in human history.
People now produced their own food. So they no longer had to wander. They could store extra food, called a surplus. A surplus could support larger populations. People built permanent settlements, often along fertile river valleys.
Agriculture made villages possible. In time, villages grew into towns and then cities. The food surplus freed some people from farming. They could become craftspeople, traders, priests or rulers. This created more complex social structures. It also led to the first civilizations. Writing, calendars, irrigation and organized government all grew out of settled farming life.
Nepal is a clear example. The Terai plains and valley floors such as the Kathmandu Valley became centres of settled farming. Farming is still the backbone of rural Nepali life today. Rice, maize and wheat set the yearly rhythm of many communities.
Over time, agricultural societies gave way to commercial societies. Later, these became industrial societies. The capitalist era has three main marks. First, land, factories and capital are privately owned. Second, goods are made for profit and sold in markets. Third, workers do wage labour.
Capitalism grew strongly along with the Industrial Revolution. The Industrial Revolution began in Britain in the eighteenth century. Then it spread to other places. Machines were powered first by steam and later by electricity. They let large factories make goods much faster than people could by hand.
The industrial world changed society. People moved from villages to cities to find factory work. This created crowded urban centres. It also created a new working class. Trade spread across the globe. New technologies appeared quickly. Wealth grew enormously, but it was often shared unequally. The factory system, money and banking, and competition between businesses became central to economic life.
Nepal never industrialized on the scale of Europe. Still, it takes part in the global capitalist system. It does this through trade, markets and banking. It also takes part through the labour of Nepali workers at home and abroad. This shows how far the industrial and capitalist order now reaches.
Today, societies are closely connected through technology, trade and communication. This process is often called globalization. The internet, mobile phones and fast transport have made distances shorter. Ideas, goods and cultures now spread quickly.
This connectedness shapes social behaviour. People build relationships online as well as in person. Information travels instantly. Events in one part of the world can affect lives far away.
Modern life also brings new challenges. Urban living, busy schedules and constant digital contact bring both opportunity and stress. In diverse and connected societies, some values matter more and more. These are cooperation, tolerance, respect for diversity and responsible citizenship.
In Nepal, mobile phones and social media have changed how people communicate, do business and take part in public life. Migration for work has also changed families and communities.
The long journey from the Stone Age to the present teaches us something. Human society is always changing. Each generation inherits the way people live together. Each generation also reshapes it.
