In the cave in the U.S. discovered artifacts from Siberia.
In an underground cave in the state of Florida discovered the artifacts, which are pre-determined in 14.5 thousand years.
Scientists believe that this is the most ancient evidence of the presence of people who came to the territory of the modern United States from Siberia through Alaska. Studies in an underground cave was conducted from 2012 to 2014, their results last Friday were published in the journal Science Advances. In the course of studying the deep holes where once was a pond, were discovered the ancient stone knife and plate. Age finds, according to scientists, is about 14.5 thousand years.
This confirms previously published theory about the settlement of the territory of modern USA in this period, called pre-Clovis pre-Clovis – all that happened on American soil more than 13 thousand years ago). The theory was based on the DNA analysis of the North American Clovis period, 12.6 thousand years ago.
According to the theory, people began to move from Siberia to the North-East of America, about 32 thousand years ago, 26-18 thousand years ago they reached Alaska, and about 17 thousand years ago, settled farther to the South. According to scientists, to the pond at the time the animals came, and the knife found belonged to the hunters.
The age of the knife were able to calculate the surviving remnants here of mastodon manure, in which were found parts of tree branches. Also the grooves on there was found the Tusk of the mastodon indicate that it tried to separate from the skull of the animal.
According to the researchers, these hunters were the people who inhabited the territory of modern Siberia, and came to America via Alaska, then spreading to the South of the country. This migration supposedly happened 16 thousand years ago people arrived on boats.
