USA HISTORY

Detailed explanation-1: -The very first Americans were big-game hunters who came from Asia and carried spears of bone and stone. They didn’t come here because they were searching for a new place to live. They were following the giant buffalo and huge woolly mammoths that they tracked and killed to survive.

Detailed explanation-2: -Drought, flood, and temperature changes could certainly push people to move on. Climate change also affects the food supply, and anthropologists have assumed that people came to the Americas because they were following food on the hoof.

Detailed explanation-3: -They wanted religious freedom and economic opportunity. The United States is a country where individual rights and self-government are important. This has always been true. Colonists first came to America for more freedom.

Detailed explanation-4: -People travelled by boat to North America some 30, 000 years ago, at a time when giant animals still roamed the continent and long before it was thought the earliest arrivals had made the crossing from Asia, archaeological research reveals today.

Detailed explanation-5: -Scientists one theorized that the ancestors of today’s Native Americans reached North America by walking across this land bridge and made their way southward by following passages in the ice as they searched for food. New evidence shows that some may have arrived by boat, following ancient coastlines.
