Americans, wrongly known as Indians, were the original inhabitants of
the Americas. Anthropologists agree that they are descended from people
who traveled to America from Asia. They originally formed small
wandering groups, hunting for food and living off the land. Later they
formed larger groups. The type of food they hunted and the ability to
store food for coming years is thought to be one of the main reasons for
the cultural differences between the groups.
The first people to live in North America are called Native
Americans. When Christopher Columbus first landed in the Americas, he
thought he had landed in India, and so he called the people Indians.
The name is totally wrong, but it stuck. Later still, a Swedish man decided that
the Natives should be given a proper name, and so he called them Americans
or the Red Race. This didn’t help much, as people then
started calling them Red Indians or American
Indians. Only recently have they been given their proper title, that of
Although all Anthropologists agree that people from Asia were the original
inhabitants, they cannot agree on when the migration happened. These original
descendants of Native Americans crossed from what is now Siberia into Alaska
sometime between 40,000 and 20,000 years ago.
At first they lived in small groups. They were nomadic hunter-gatherers. This
means that they moved around in search of food, hunting wild animals and
gathering wild plants to survive. This type of living can only support small
groups. People living like this build small shelters, from animal skins and
poles that can be moved easily. They may also build using poles, branches and
grass, and just abandon their homes when they move on. They tended to move
southwards, in search of food, as food was more plentiful in warmer climates.
As some groups moved further south, they found that they were able to grow
their own crops. These groups were agrarian, meaning they planted and harvested
their own crops. The ability to grow crops meant that there was enough food to
support a larger group. The groups became larger and more permanent. Homes
became more elaborate, and less movable, and small villages started appearing.
At this stage, they were still unable to store much food. This meant that in
years when they had a bad harvest, they didn’t have enough to eat. Two or more
years of bad harvests following each other meant they had to move again, or face
As the groups became larger, and moved further south, they learned valuable
lessons on the way. Not everyone moved south. Those who stayed remained in
fairly small groups, or tribes, and were able to support themselves with the
farming and hunting methods they already used. Most of the tribes who remained
in North America had less than 1000 people in each group. The size of the group
depended on the availability of food. In some areas, where food was plentiful,
the groups were much larger.
As the groups neared Central America, they learned how to irrigate crops.
They found ways to bring water to their fields. This meant that they could grow
more crops, and even store food for years when the harvest didn’t supply enough
food. They also learned how to terrace and fertilize, growing much more food
over a small area. These groups were able to support a much larger number of
people. They built permanent homes, and eventually very elaborate civilizations
grew up, with towns and cities.
The Native Americans from these areas are known as the Nuclear Americans.
They lived in the southern part of North America, Mexico and Central America.
From these groups the Aztec, Mayan and Inca civilizations grew.
It seems that the groups that continued on to South America did not take with
them the agricultural knowledge of the Nuclear Americans. Or perhaps they chose
not to use it, or it was unsuitable to the areas they lived in. It is also
thought that a second migration of Asians, this time from South East Asia, may
have reached South America 6,000 years ago. The groups in South America were
again small groups of hunter-gatherers. They tended to settle in one area, but
remained in small groups who did not need to move in search of food. Their
groups were small enough, and food plentiful enough, that they were able to stay
in the same region. They built permanent but very simple homes.
Small groups were formed of immediate family members, usually ruled by the
oldest male. Larger groups or tribes were also built around family, but a much
wider family. These groups usually had one branch of the family that ruled, the
rule being passed down to the next generation of the same branch. The much
larger civilizations of the Nuclear Americans had complex societies with levels
