The first settlers of North America appear to have been from the Japanese Isles

Excavation of the Nipehe site

New excavations at Cooper Ferry in West Idaho show that humans lived in the Columbia Basin for about 16, 000 years. At least that is the age of the fire pit and fragments of tools found in a place called "Nipehe" - an ancient site or village. The problem is that, according to the general idea, people in North America could have appeared only after 2000 years - with the birth of the Clovis culture.

The current theory suggests the settlement of the North American continent from Asia, across Siberia and the ancient land bridge that existed at the site of the Bering Strait. It happened about 15, 000 years ago, with the beginning of the melting of huge ice sheets, which opened the way between the continents. But soon the ice began to move again and the road disappeared, and the surviving settlers began to move south. They are known as the Clovis culture, from which all the Indian tribes of the continent then descended.

The fragments of spear and arrowheads found in Nipekh are not only older than the Clovis weapons, but they are also of a fundamentally different shape. Clovis made a groove in a flint shard to be inserted into a spear or arrow, and the tips from Nipehe have a protrusion for which they are attached to a wooden base. Just like the instruments from the island of Hokkaido, dating back to the same millennium.

The characteristic appearance of the arrowheads led to the creation of a new hypothesis. The settlers who gave birth to the Clovis culture passed through the land at the site of the Bering Strait. They moved along with the migration of a huge number of animals, just following the food. But 1-1, 5 thousand years before this, a certain tribe from the Japanese Islands, driven by someone or something, could manage to pass along the edge of the ice, through the narrow and dangerous Bering Bridge that had just appeared. In order to go as far as possible deep into the unknown continent, where they disappeared - apart from the debris from Nipehe, no traces of this culture have yet been found.
