many scientists believe that the earliest people in North Americans may have traveled here from the continent of Asia many thousands of years ago. At that time, Earth was experiencing an ice age. much of the water that separates the northern parts of asia and north america would have been frozen at the time. it may have formed an ice bridge that people were able to walk across.
perhaps they were hunters following their food. Perhaps they were adventurous. We do not know for sure. Their migration to North america however may make them the grand forefathers of the people we call Native Americans. we do know that the earliest North Americans were nomads. They traveled from place to place instead of setting in one place. Eventually these nomads began to find permanent settlements.
They had already learned to gather plants growing in the wild forests. After a time, they began to learn about agriculture. agriculture is raising plants and animals for human use. with better sources for food, they did not need to move around to look up for it so much.
at they began to look for more permanent homes, they paind attention to the resources of specific locations. they wanted to live near water sources such as streams or rivers. this helped to make sure that they could water their crops and take care of the water needs of humans and animals. It is not surprising, then, to discover that most early villages were located very close to water sources.
people moved around less often than before. howevet they were still slowly migrating to other areas. every time a group or tribe moved into a different natural environment they had to adapt (changed themselves) to the climate and resources of that area. the clothing they wore the kind of houses they built and even the kind of food that they ate depended upon the region in which they lived.
