The earliest humans evolved, it is thought, in Africa. After thousands of years, they began to move to other parts of the world. By about 30,000 years ago, they had spread to every continent of the world except Antarctica.
As people settled in different parts of the world, different ethnic groups emerged. These are large communities of people who have physical characteristics, languages, religions and other traits in common. People developed languages so that they could communicate with each other. Different cultures, including art and religion, soon followed.
People have moved around throughout history, because of the opportunities offered by the discovery of new lands, or for better economic prospects. War or natural disasters such as flooding or drought have also led to mass-migrations of people. When groups of people settle in a new country, they often bring their own religions and cultures with them. Some nations, such as the United States, are now considered multicultural.
In a very few parts of the world, people still live as they have done for thousands of years, although nearly all are affected in some way by the modern world. Natives still hunt and fish in the Amazon rainforest just as their ancestors did. Their lifestyle is threatened by destruction of the forests.
