Bering Strait Immigration Theory

Scientists have always believed that Native Americans on the American continent are descendants of a group of primitive humans who crossed the frozen Bering Strait and first lived in East Asia. The latest large-scale genetic research fully supports the above speculation, and it is also found that Native Americans come from the same group of humans. The analysis of genetic variation shows that the indigenous people in the whole American continent have the same unique genetic variation from Siberia to Bolivia. This means that about 12000 years ago, humans from a single source crossed the Bering Strait continental bridge in one or more waves. In addition, the study also found that primitive humans extended to South America along the coastline, not through the inland.
