In ancient nomad camps Aleuts found the remains, allowing to make the dating using radioactive "clocks". They gave the age of three thousand years. Then, by comparing the main part of the Eskimos and Aleuts lexicon via the so-called linguistic "hours" - or method glottochronology - time division eskaleutskogo language Eskimo and Aleut determined was 2,900 years. The coincidence of these radioactive and linguistic "clock" was considered one of the nadezhnyhsvidetelstv that "watch" these are synchronous. But if the course of linguistic "hours" as objective, as well as the course of the "clock" of radiocarbon, similar results should provide a variety of languages. Testing also showed that is not always possible to obtain a coincidence of language and hours of time that show objective evidence. More than a thousand years ago the Slavs - Russian, Belarusians, Ukrainians, Czechs, etc. -.. Had their own languages, statehood, writing. And according to linguistic "clock", Russian and Czech languages ??diverged four - five hundred years ago, the Czech and Polish - hundred - four hundred years ago. Exactly the same if different linguistic evidence "hours" and historically attested facts given and other languages: Icelandic, Armenian, a number of ancient dialects of Central Asia. And then followed a sensational discovery made by Soviet and American archaeologists during their joint excavations in the Aleutian Islands. It turns out that the Aleuts ancestors lived here not three thousand years ago, and seven and a half or eight and a half thousand years to the present day! However, they had already established culture, which is a sure indication that the Aleut culture has started to develop much earlier, about ten thousand years ago. But this - the era of the death of Beringia. Perhaps this was the cause of death and the fact that the old hunters of mammoths and other big game turned in the sea hunters?
