How did the Indians come to America?

Some of the earliest inhabitants of America were Indians. When Columbus was in discovery of america at the end of15th century, he mistakenly thought that it was India in the east, so he called the local residents "Indians", that is, the residents of India. This historical misunderstanding has been used for a long time and has become a special term to address Native Americans and their descendants.

However, according to archaeological excavations, no ape-man fossils have been found in the American continent. Although it is a cultural site unearthed with human beings, it belongs to the late Paleolithic period. Therefore, scientists speculate that the inhabitants of the American continent may have migrated from other continents. According to textual research, Indians and Asian yellow people belong to Mongolian race, but how did they come to America?

It turns out that the Bering Strait, which connects Asia and America, once fell about 70,000 years ago. Some places are exposed to the ground, forming a "land bridge"; About 1500~2500 years ago, the "land bridge" was submerged by seawater again. Therefore, it is speculated that during the existence of the "Continental Bridge", Indians started from the northeast corner of Asia to Alaska, where the sun rose, and then gradually spread to the whole America from north to south.

After the ancient Indians arrived in America, due to different conditions in different places, they formed various races and languages, and their development levels were also very different. /kloc-before the invasion of European colonists in the 0 th and 5 th centuries, most Indians were still in the stage of tribal communes, but in some areas, the seeds of slavery have appeared. Among them, Maya, Astek and Inca once established three brilliant Indian cultural centers in Central and South America.

Indians are industrious and intelligent people. They created letters and calendars, and invented the number "0" in the world, which can be used in some surgical operations. They built a pyramid similar to Egypt in a city where100000 people live; More importantly, they have cultivated more than 40 kinds of crops, such as potatoes, tomatoes, corn, tobacco, sunflowers, cocoa and coffee, all over the world, which greatly enriched the material life of mankind. Later, because of the invasion of European colonists, he ended his cultural history.
