How humans arrived in the United States, the kelp highway hypothesis, rewritten the history of the first settlers
Until the 21st century, it was generally believed that the first humans arrived in North America from the present Russia and Alaska via land bridges. Since then, anthropologists have been dismantling the timeline of the theory. Now, they believe that the earliest humans in the United States did not even arrive by land.
In a new comment on the evidence, six famous anthropologists invested their power behind the "kelp highway hypothesis", which led to the first group of humans in the United States to travel by boat to the algae forest biodiversity along the glaciers.
"In a dramatic turn of knowledge, most archaeologists and other scholars now believe that the earliest Americans traveled along the Pacific Rim from Northeast Asia to the Bering Sea and the Americas," the author of the new perspective wrote in the journal Science . "But the evidence to find this decentralized route is still elusive."
Earliest humans in the United States were Clovis
According to the older "Clovis First" theory, the
earliest humans in the United States were Clovis, who were hunter-gatherers who
came here about 13,500 years ago. The Clovis people did come here at that time,
and they did cross the ice-free corridor.
But most scholars no longer believe that they are the first-there are former Clovis people, who came here between 17,000 and 20,000 years ago. Now, the evidence pointed out by the researchers reveals how early groups can achieve this goal.
"We hope this paper does a few things," the first author of Todd Brager, associate professor of anthropology at San Diego State University, told Newsweek via email. "
1) Highlight the Pacific Rim Coastal Route, which has been marginalized for decades, but has now become the mainstream of archaeologists;
2) Emphasizes the need to explore the continental shelf, where there are large swamps of submerged landscapes used by the first Americans . "
The authors point to recent archaeological evidence, such as skeletal remains from Santa Rosa Island, California, which collectively support the view that Clovis' predecessors lived in various places along the North American coast.
"The author writes that the uncertainty left by the collapse of Clovis' first paradigm has opened up a series of alternatives for Pandora for the American population, and some scholars and members of the public quickly accepted the incredible claims. Ambiguous evidence. "
As the glacier began to recede 17,000 years ago, the warm water in the algae forest-across the coast of Japan to California-will provide the earliest settlers in the United States with everything they need to travel along the Pacific Rim coastline.
Recent anthropological fieldwork along the coastline found evidence that they were resolved during that time.
