Describe indian populations and development at the time of european exploration

Before that time, the continent was an unknown place to them. These adventurers saw it as an entirely new land, with animals and plants to discover. They also met new people in this exciting New World—people with fascinating lifeways that the Europeans had never seen and languages they had never heard. This New World for Europeans was actually a very old world for the various people they met in North America. Today we call those people American Indians.

Explanation:

Archaeologists tell us that American Indians may have been on the North American continent for fifty thousand years. They were the first Americans, and they were great explorers, too.Over time, their lives changed as they adapted to different environments. American Indians were creative. They found ways to live in deserts, in forests, along the oceans, and on the grassy prairies. Native peoples were great hunters and productive farmers. They built towns and traded over large distances with other tribes.As the English, French, and Spanish explorers came to North America, they brought tremendous changes to American Indian tribes. Europeans carried a hidden enemy to the Indians: new diseases. Native peoples of America had no immunity to the diseases that European explorers and colonists brought with them.
