A new study found that the first people to colonize the US used to migrate from modern-Russia about 20,000 to 30,000 years ago.
Published on 15 May In Journal ScienceThe study shows that the languages and traditions of indigenous groups living in the US can be found back in the early settlers of thesis today. Their cultures are present in the genes of modern indigenous groups.
The study found partitions in early settling groups that were isolated in various environmental settings. Researchers stated that this discovery provides a new genetic and cultural understanding of the present South American communities.
,[It fills] Elena Kusareva, the lead writer of the study, said, “The main interval in how the current population of the present South America took place is based in the Nanyang Technological University, Singapore.
Kusareva said that in the study, the participants had “intended” to the bees to highlight the history of their people. This showed the importance of ancestral knowledge for the identity of the people, said Kusareva.
The researcher cited an “immediate case” involving people in Patagonia, whose population and 6.000 old cultural heritage are in danger of disappearance: “This genetic record is the last chance to preserve their heritage.”
Eurasian roots of indigenous Americans
Kusareva and colleagues took a sequence of genomes of 1.537 persons of 139 ethnic groups in Northern Eurasia and America.
He compared the thesis with millions of small changes on the modern day to the first people coming to the US with the genes of indigenous people with ancient DNA. He said that it already created a genomic dataset from at least people in ancestral science.
How the thesis genetic codes in different geographical regions and people of different indigenous groups were allowed to study the pattern of population history, migration and adaptation over thousands of years.
“Our genetic analysis of indigenous groups is important that the region has a unique insight in human history as soon as possible,” said Hi Lim Kim, a genetic, Nanyang Technological University, a colleague.
His analysis confirms the existing archaeological evidence, which shows the first people in the US from North Eurasian to 26.800 years ago.
The dates “correspond to a large body of archaeological evidence,” Francisco Xavier Acetuno said, the staunchist at Antocia, Columbia, who was not involved in the new study.
Comparing the genetic dataset, researchers stated that they were able to find the closest living relatives of indigenous North Americans, West Bringian Group, Intete, Korox and Luorvetlance. The modern day during the previous ice age was on a snow bridge between Russia and North America during the previous ice age.
Foundation of indigenous groups of South America
After the study of Gusreva and Kim, it was found that the early settlers had come to South America and then divided into four separate groups -Amazonian, Andian, Chacko American and Petagonians -they were isolated into each different environment.
Aceituno told DW that these groups of hunters perhaps “to capture new areas, to generate new family groups and avoid separation.”
Kusareva believes that new genetic data reflect natural barriers, discovering the Amazon Renforest and Andes Mountains, leading the thesis leading the separation of indigenous groups.
Kusareva said, “This made her genetic makeup more equal, which is a Sen in the population of the island.”
Ancient gene mutations affect the health of modern South Americans
The study found that indigenous groups have different genetic symptoms, which may develop through long-term isolation from extreme environment hands and other groups.
For example, a group of Andian Highlanders carries a gene mutation that helps them to adapt to low levels of oxygen.
Mutations in gene EPAS1 stimulate new blood vessel formation and produce more red blood cells. The EPAS1 mutation has been found in the people of Tibet.
“As people are optimized for diverse and often extreme environment – such as high altitude or cold climate – their genomes developed accordingly,” Kim said.
Previous studies have found that genetic variations between indigenous groups of Brazil were a different theme theme for blood clots or drugs for high cholesterol.
Kim said that more than 70 gene variations have been detected in the new research that may occur in the sun [people’s] Reporture for emerging infectious diseases: “Many of these population are already small. It is important to provide efforts to suit their well -inch to suit their well inch.
