During the excavation of ancient primitive people in Alaska, scientists have discovered the bones of salmon age of 11 500 years, with traces of heat treatment. This is evidence that the first migrants who moved to America from Eurasia, caught big fish. Previously it was believed that the Paleo-Indians ate mostly game. About his discovery, scientists reported in the journal Proceedings of the National Academy of Sciences. The value of the discovery that fish bones - a very small and fragile. Typically, these remains poorly stored in the ground. Carefully sifting through the sieve of soil dug at the site of an ancient hearth, Karrin Halffmen (Carrin Halffman) and her colleagues, archaeologists have discovered the bones of salmon. DNA analysis showed that this chum salmon (Oncorhynchus keta). ThoUSAnds of fish every year to spawn in the sea in the nearby Tanana River, and this event is important for the local Athabascan Indians. Analysis of carbon and nitrogen isotopes in the bones of the fish confirmed that salmon Paleo-Indians, as well as the present inhabitants of Alaska, is caught during the annual spawning. Thus, there is the first evidence of the important cultural phenomena of local residents. archaeologists suggest that the ability to catch the first salmon helped the Indians to diversify their diet and to survive when the territory of Alaska has been cut off a big game. According to the latest genetics, the first Americans were immigrants from Siberia, who migrated no earlier than 23,000 years ago, in the harsh period of the last glacial maximum. Then, at least 8000 years the ancestors of the Indians held in Beringia - paleogeographic area where now the Bering Strait. Only the melting of glaciers (about 13 thoUSAnd years ago), they opened the way to the region, located in the heart of the continent.
