Sorry, Chris Hemsworth and Travis Fimmel, Copenhagen University published the results of his research DNA Viking. And it turns out that most Vikings were not blond and blue-eyed, according to legends and pop culture. Dark hair and dark eyes met more often.
The study covered the remains of 442 of the Vikings buried from 2400 to our era to 1600 of our era. And has shown a greater genetic diversity than previously thought. Not only was the minority blond and blue-eyed, but also a comparison of genes proved that the Vikings were not a separate ethnic group, but were a mixture of groups "originating from hunters-collectors, farmers and the population of Eurasian steppes." The most genetically diverse areas - one in Denmark and one at the Swedish Islands Gotland and Eland - most likely were large shopping centers.
Science magazine, with reference to the archaeologist Kat Jarman reports that being Viking at that time meant a lifestyle or work, and not belonging to a specific ethnic group:
Two wiking skeleton, buried on the Northern Islands of Scotland, are pure Scots or Irish from the point of view of genetics, without any scandinavian influence. Several people in Norway were buried as Vikings, but their genes identified them as a Saami, an ethnic group, closer to Asians than to the Europeans.
