The evidence of a diversified economy based on the sea of the ancient settlers of North America, is coming to light after finds at three different canal sites in the California Islands.

In a report published on March 4, a 15-member team led by the University of Oregon and the Smithsonian Institution described that dozens of projectile tips and crescents have been found dating to between 12,200 and 11,400 years ago. These objects are related to the remains of mollusks, fish, geese and seals among other marine animals.

In addition, thousands of objects made of flint rock have been found, which was used to make projectile points and other instruments. Some of them are very delicate for practical use and would only serve for the "hunting in the water”, Expressed the Professor of Anthropology Jon Erlandson, who is also the Director of the Oregon Museum of Nature and Cultural History.

This is one of the first tests of navigation and maritime adaptations of the Americasand added that the objects foundThey are extraordinary and show amazing workmanship. They are ultra thin and serrated, featuring very sophisticated stone chip technology for the time.”.

The objects have been recovered in three sites of the San Miguel Islands, which in the Late Pleistocene, at which time these artifacts were dated, they were connected as a single island to the coast of California.

The technology presented by the objects makes it clear that could not belong to the terrestrial culture of the Clovis, but they are similar to those that have been found in the Great Basin. In addition, they found that they have a great similarity with vestiges that have been found in the so-called Pacific Rim, which runs from Japan to South America.

However, it is not clear how they could have got there, although Erlandson proposes thatDuring the Late Pleistocene high seas, people may have followed an algae path that stretches from Japan to Kamchatka, along the southern coast of Beringia and Alaska, and thence south along the northwest coast of California. . The Kelp forests are rich in seals, otters, fish and shellfish, so the raw material to make the objects was”.

This discovery gives a very different image to that of the ancient inhabitants of the Canal, also indicating an early maritime adaptation unmatched throughout the Americas, at least for now.

After studying History at the University and after many previous tests, Red Historia was born, a project that emerged as a means of dissemination where you can find the most important news of archeology, history and humanities, as well as articles of interest, curiosities and much more. In short, a meeting point for everyone where they can share information and continue learning.
