After more than years of research, an international group of geneticists have proved that Aztecs, Incas, and Iroquois are closely related to people of Altai, the Siberian region on the borders of China and Mongolia.
The theory suggests that people of Altai Siberia across Chukotka and Alaska, down to the Tierra del Fuego at the tip of South America, appeared a century ago. In late 2015, a Russian geneticist, Oleg Balanovsky, approved the theory and also proved that some native Americans are related to indigenous people of Australia. “The current study confirms the theory that the Altai people are closely related to native Americans,” said geneticist ValeryIlyinsky at the RAS Institute of General Genetics.
“We now have clear proof, and it is useless to contest it,” he said. In 2013, top scientific magazine, Nature and Science, published the analysis of whole new genomes in Native Americans and Siberians are cousins. A comparison was made with populations in other regions throughout the world.
The first study analysed 48 people from Brazil, the second study analysed that 31 genomes from people in the US and Siberia around 20,000 to 30,000 years ago. In the first stage of the study, scientists analysed DNA samples from the Russian Biobank. “Our biobank contains more than 25,000 samples from representatives of 90 nationalities in Russia and neighbouring countries,” Dr Balanovsky said. In the second stage, the DNA was analysed according to many criteria such as the Y chromosome that is a male hormone, as well as the mitochondrial DNA that is of a female.
As a result, scientists proved beyond doubt that Americans are closely related to the people of Altai. “Besides Siberian ancestors, some native Americans showed a puzzling relation to the indigenous peoples of Australia and Melanesia in the Pacific Ocean,” said Dr Balanovsky. “This is astounding because they are located in an almost opposite part on the planet,” he said. “Instead of the Bering Strait, there was a land bridge [30,000 years ago] because during the Ice Age much water was locked in glaciers and the level of the world’s oceans was lower,” Dr Balanovsky said. He also said it is not yet clear whether migration from Australia and Melanesia to the Americas was direct across the coast and through the Aleutian Islands.
