How did America's first 'immigrants' get here? A new study says they used both inland and coastal routes

The first route from Asia to the Americas - and when it happened - has produced decades of research

Currently, a new study concludes that the current inland route of Western Canada and the route along the Pacific coast should be considered as the first possible way for humans to enter the Americas.

The inland route theory known as "No Ice Corridor" means that humans cross the current Alaska and Yukon regions and then turn right between the two huge ice floors. Later, they will hike along the British Columbia / Alberta border to the northern plains of the United States of America today. This theory is the most established idea of ​​the 20th century.

Another "North Pacific Highway", also known as the "Sievert Highway", shows that humans moved along the North American West Coast and became popular assumptions in the past 20 years.

Ben Porter, the lead author of the University of Alaska Fairbanks said at the press conference earlier this week, "We can not rule out the first coastal or inland route of the Americans." "I think that both of them were used"

He says, "What we want to do is to provide a framework for discussing demographic processes - not based on speculation but based on a careful and critical review of our existing evidence ".

"It is not confusing, archaeological records, paleontologic records, genetic records are consistently growing," he said.

"As opportunities to genetics, archaeologists, indigenous communities respect and cooperate in mutually beneficial ways, opportunities to analyze other people to infer the history of the American population are on the rise."

The population does not show up at the same time: it occurs in "pulsation" of population movement. Porter said the current evidence suggests that Native American ancestry had three major branches.

A group of South American indigenous peoples penetrated into the Americas. Another group is North American Aborigines now North North America.

The third group of ancient Behring schools is in the northern Berinzia, and today in Alaska and the Yukon. (The Bering Sea is a land covering Siberia and Alaska, most of which no longer exist.

As to when this happened, the data indicated that "the population occurred between 16000 and 14000 years ago," Potter said.

"Now, I guess we know it is premature to make sure of it," Potter said. "We have stated that there is not enough evidence - we need more science on both paths," he said.

But what route did the first Americans follow: inland or coastal corridors? Archaeologists have discussed this issue for a long time. For the most part of the 20th century scientists believed that ancient people crossed two huge ice sheets between the North American ice free corridors. But over the past two decades, more archaeologists have supported the coastal Kelp Road idea. Part of the reason is unknown whether the ice free corridors will emerge sufficiently early enough to accommodate the dates of the American known sites and whether this corridor can support a group of migratory birds That is why.

For decades, this problem has plagued researchers. Well, although archaeological, geological, anthropological, and genetic data review considers both, especially for the latter, prehistoric humans seem to prefer inland routes. According to the expedition, new comments. However, not everyone believes this is the fact. Several recent studies show that the coastal route is the preferred route. This is because the conditions in the inland area are too strict before the ice sheet subsides and according to some studies it shows that this happened for the first time after the establishment of the first settlement in the United States I will.

As a new team in our organization, we need to explain what is going on in the inland. Sometimes we say that the hinterland is "Innovation Institute in Immigration Bureau of Finland" (Migri). Whenever you say it loudly, do you want to know what it means? What is interior innovation? How do you measure success? A few months ago, we were still looking for ways to communicate various kinds of projects inland that were carried out inland, ie digital project, process redesign, solution expansion, and stakeholder network construction. We need to decide how much time is allocated in inland areas to various projects and plans.
