21/2021: Bering land bridge VS. Coastal migration

 Migration Theory

Bering Land Bridge:

    Bering Land Bridge theory is how humans in the stone age built a land bridge across from Siberia to Alaska then later the New World. This theory was started in the Renaissance time by many Europeans trying to understand why humans were able to settle down in the new world. They began to discuss a land bridge stretching between Asia and North America 20,000 years ago. 

In early 1590, the Spanish missionary, Fray Jose de Acosta was the first person who published writings about the “Bering Land Bridge ''. Later, Peter the Great of the Russian empire visited the Chukchi peninsula (Alaska) in 1682-1725, but still no sign of a land bridge.

In the 1800s to 1900s, many American scientists searched areas around the west coast and tried to find the land bridge, but no sign. Later David M. Hopkins searched the range background of the Seward peninsula of Beringia. Then Hopkins found out with his team of Mary Edwards, Claudia Hofle, and Victoria Goetcheus Wolf about the eruption of Devil Mountain 18,000 years ago, in which most of its ash became a thick ground on the ice between Siberia and Alaska. They discover this from the plant in the area. Because of the Colvis, humans arrived in the southwest of America in about 13,500, but how did the people in Monte Verde in Chile which is 14,500 years old. So this led to the Coastal migration theory.

Coastal Migration Theory: 

Coastal Migration theory is how Colvis humans built a boat or kayaks and sailed across from Siberia to Alaska and Southeast Asia through the island in the Pacific to Southern America during 15,000. In that time, stone age people were able to build boats to Japan, Kamchatka, and Korea, so they might move to other islands in the pacific ocean too. This idea also proved that a village called Monte Verde in Chile is 14,500 years old which is older than the land bridge that the first stone arrived in Chile in about 1,000 years later. 

After the archeologist found the village, they began to search for more villages along the west coast and they found more tools made from rocks and shells which related to the native Americans. Because the ice age began to melt in the 16,000 the ocean level increased to 120 meters, so they began to research the ancient river bank under the pacific coast and they found more stone tools. 

This ice melt also makes the land of British Columbia and Alaska rise up after losing weight. Then they found the human footprint on the Calvert island of British Columbia, so the Colvis human might land on that island in the search for food and fresh water. Could they stop on the island or along the coast?

Both of the theories have the same points as animal hunting, the DNA of native Asian people and native American people, and the Kelp highways. The Bering land bridge has an advantage on the stories of native Americans about how they arrived by crossing to Alaska. The only opposite advantage for Coastal theory is “how did the Colvis humans arrive in Chile before land bridge theory 1,000 years ago?”

Some evidence from coastal theory is able to be supported by some part of the land bridge theory of Kelp highways evidence used to be along the coast of North-west America. The last part of the land bridge theory doesn’t have evidence about the village in Chile. After all of this information, the land bridge theory is trustable than the Coastal theory because it’s really older.
