Where the First Americans came from

Many people were thinking about where the first people get to the new world. It has taken a couple million years to spread across the plant. Humans lived in Africa. However, Modern humans left Africa but not long afterward. Scientists used the fossil to follow humans’ movements. Humans moved from East Africa to South Africa onto the Arabian Peninsula. After thousands of years, Modern Homo Sapiens migrated throughout Europe and Asia. Supplanting or interbreeding with population of Neanderthals or Homo. So, modern humans moved to the New World and populated there. The scientists were thinking about how humans made it over there, because the map makes it look so far has been a puzzle without many hypotheses. Before DNA, scientists looked at fossil and traits and geologic record and theorized humans moved onto to land bridge which found between Asia and North America. The Bering land bridge land probably conjures pictures of well, a tiny little bridge. However, the bridge is a huge. It is called The Bering Plain. It is also connecting the two continents Asia and North America. People moved onto the bridge 23,000 years ago, then they moved off the bridge maybe 15,000 years ago. New science has confirmed most of the Bering land bridge theory and how the first people or Native Americans found their way into this continent. Since 2003, sciences have baseline about Native Americans. They moved from Siberia in a single wave and settled in the North for thousands of years. They split into two groups about 13,000 years ago. One group settled throughout North America and while the other settled in the Central and South America. According to the genetic information, Native Americans have a small mix of genes from East Asians and Australo-Melanesians. Today, more than 80 percent of our planet has seen influence from humans activity.
