Question

How did the first americans get to the america

Answer 1

Hint: How did human beings arrive in North America first? Across the Strait of Bering, on foot? "By boat down the "Kelp Highway"? Via the polar ice cap across the Atlantic? When did they get here? Ten thousand years ago? Fourty-thousand? Or, as the Navajo and other Native American tribes say, were they always here?

Complete answer:
When Paleolithic hunter-gatherers entered North America via the Bering Land Bridge from the North Asian Mammoth Steppe, which had formed between northeastern Siberia and western Alaska due to the reduction of the sea level during the Last Glacial Maximum, the settlement of the Americas is generally accepted to have begun.

The "Clovis first theory" refers to the hypothesis of the 1950s that the Clovis culture represents the earliest human presence in the Americas, starting about 13,000 years ago; since 2000, evidence of pre-Clovis cultures has accumulated, pushing back the possible date of the Americas' first population to 33,000 years ago.

Archaeologists have thought for decades that the first Americans were the people of Clovis, who were said to have entered the New World from northern Asia about 13,000 years ago.
But recent geological discoveries have confirmed that thousands of years before that, humans entered the Americas.
Together with observations from genetics and geology, these findings have sparked a rethink about where these pioneers came from, when they arrived, and what path they took to the New World.

Note: 1)The pattern of migration, its timing, and the place(s) of origin in Eurasia of the peoples who migrated to the Americas remain uncertain, as there is general consensus that the Americas were first settled from Asia.

2)Over the past decade or so, as a result of new observations, this Clovis First model has come under sharp attack.
