Genomic analysis shows that the viking population's genetic "footprint" throughout Europe

, Sept. 17 (Xinhua Zhang Mengran) -- A genome analysis of more than 400 european ancient humans published in the British journal Nature on the 16th revealed the genetic make-up across the millennium. The study showed that it was different Viking populations that influenced the genetic make-up of various parts of Europe.
sea expansion of the Scandinavian population during the historic Viking period (750-1050 A.D.) changed the political, cultural and demographic map of mankind. They operated on European coasts and British islands from the 8th to the 11th centuries, and their footprints are thought to extend across the continent to the Arctic.
To explore the effects of this period on the human genome, this time Isaac Willes-Lever, a researcher at the University of Copenhagen in Denmark, and his colleagues sequenced the genomes of 442 ancient humans from across Europe and Greenland, spanned from the Bronze Age (about 2400 D.C.) to early modern times (about 1600 A.D.).
found that in the "Viking era", foreign genes from the south and east flowed into Scandinavia. They also found evidence that the Vikings had moved outside Scandinavia: the Vikings of Denmark moved to England; the Vikings of Sweden sailed eastwards towards the Baltic States; and the Vikings of Norway moved to Ireland, Iceland and Greenland.
, however, their genetic analysis also included blood samples that were related to the present-day Swedish population on the western edge of Europe and the modern Danish population to the east. The researchers believe that these individuals come from communities with mixed ancestry and are further integrated through complex cross-cultural and cross-continental trade and settlement.
During the genetic analysis, the team sequenced the genomes of 34 Viking individuals from a cemetery in Salme, Estonia, and found evidence that close family members were involved in an expedition in which four brothers were found buried side by side. They also identified two other pairs of relatives in the data set, but the relatives were found hundreds of kilometers apart. Combined with the above findings, the team believes that it can explain the existence of individual movements at that time.Today's people are no strangers to the determination and analysis of gene sequences, a technique that has gone from laboratory to clinical application to accurately determine the type of disease people suffer from, the likelihood of predicting disease, and even the behavioral characteristics and behavioral rationality of some individuals. Now, scientists in the field of genetic research more and more in-depth, gene data accumulation is more and more, and the addition of ancient genetic analysis, for human genetics combed a clear development of the vein, for anthropologists, ancient human sequencing is for them to open a window back to history.
