There are many different theories on how Native Americans reached the Americas. The three most widely accepted theories are the land bridge theory, the coastal route theory, and the across the atlantic theory. All three theories are highly debated. The theory that is the most plausible its the land bridge theory.
The land bridge theory states that Native Americans crossed the Bering Strait from Asia to the Americas. The land bridge theory was created by Jose de Acosta in 1590 and has been accepted since 1930. It is believed that the first Americans crossed over the land bridge while tracking game. Archeologists believe that the first Americans migrated across the land bridge between eleven and fourteen thousand years ago during the last ice age. As the ice melted the sea level rose covering the land bridge and trapping the immigrants in America. The land bridge theory is the most plausible theory because it could have been completed with the limited kind of technology they had at the time and there is evidence to support it.
The coastal route theory states that Native Americans reached the Americas by …show more content…

It states that Native Americans are descended from Eastern Europeans that sailed across the Atlantic and reached the Americas. There is little evidence to support this theory making it hard to believe.Some people believe this theory to be plausible because of DNA similarities of both native Americans and Siberians. The DNA evidence used to support the theory was from a 24,000 year old arm bone of a Siberian child. They have also found other DNA from the same site from around 17,000 years ago which shows the same genetic traits. Those are the only scraps of evidence that supports the across the Atlantic theory. This theory is the least plausible because they they would have needed to have advanced technology, knowledge, and supplies to have survived the long and treacherous journey across the Atlantic
