Products of the Selet culture
In the early Paleolithic, one of the European population groups that lived in Germany and Eastern Europe used Solutrean-type arrowheads, the prototypes of which are known in local cultures. In Western Europe, the Solutrean technique was not then used. Then the proto-Lutreans were replaced by the people of the Aurignacian culture. In layer 2, Kostenok 1, a change of the proto-Lutreian culture to the sites of the Middle West European Aurignacian is noted.

Aurignac culture
In the Kostenok 2 layer, they were again replaced by carriers of the proto-Lutrean culture. The same cultural change is known in Moravia and Germany.
However, the latest date of the Selet monuments is 30 thousand years BC, and the earliest Solutrean 23 thousand years BC.
Scientists say that perhaps a specific branch of the Solutrians, which was adapted to the marine environment and migrated across the North Atlantic along the ice front to colonize the east coast of North America, and this group did not share all the cultural characteristics of the Solutrians.

Most scientists rejected the hypothesis, believing that, firstly, the Solutrean culture reached its highest development long before the Clovis culture, and secondly, the ancient man was hardly able to cross the Atlantic. Essentially, neither the supporters nor the opponents of the hypothesis have irrefutable and substantial evidence, therefore the question of settling America has not yet been resolved.
But if we accept the whole theory of Alfred Wegener, then there were no problems with relocation.
The completely preserved skeletons of the Clovis culture were not found, so scientists don’t know what they looked like. Although the disaster swept the traces of the population of North America, but it could persist in Central and South America until the advent of the Mongoloids and the heyday of the culture of the Indians. In South America, the remains of people with severe Negroid and Melanesian characters are present. It is believed that the Negro-Melanesian population of South America, allocated in 10 thousand BC assimilated later came by the Mongoloids.
