New analysis of the remains of 38 people who lived as well as died inward the town of Sigtuna during the 10th, 11th as well as twelfth century reveals high genetic variation as well as a broad scale migration. The report is the largest of its form so far inward Sweden as well as a combination of several methods, including deoxyribonucleic acid analysis as well as Strontium isotope analysis of teeth.

The analysis is based on a combination of methods from archeology as well as osteology, including deoxyribonucleic acid analysis as well as Strontium analysis of the teeth (isotope as well as degree of Strontium inward teeth varies depending of where the private lived inward their youth). The results are clear: roughly one-half the population of Viking historic menstruum Sigtuna originated from exterior Mälardalen.
"We´re used to thinking of the Vikings as a travelling kind, as well as tin laissez passer on the sack easily flick the schoolhouse books with maps as well as arrows pointing out from Scandinavia, as far as Turkey as well as America, only non so much inward the other direction," says Maja Krzewinska, researcher at the Archaeological Research Laboratory, Stockholm University as well as primary writer behind the study.
Roughly one-half of the individuals examined grew upward inward or roughly the Sigtuna area. The other one-half is every bit divided inward to regional immigrants (from southern Scandinavia, Kingdom of Norway as well as Denmark) as well as long-distance immigrants from farther away: the British Isles, Ukraine, Lithuania, northern Deutschland as well as other parts of key Europe. The immigration to Sigtuna was mutual for both males as well as females. Approximately lxx per cent of the woman someone population was immigrants, compared to 44 per cent of the men.
"The archaeological tape from Sigtuna never ceases to fascinate as it shows such a broad diverseness of cultural expressions. And hither nosotros regard who grew upward at that spot as well as who moved to Sigtuna," says Anna Kjellström, osteologist at Stockholm University as well as 1 of the authors of the study.
"I peculiarly similar that nosotros discovery 2d generation immigrants alongside the buried, that form of migratory information has never been encountered earlier as far as I know," says Anders Götherström, 1 of the leaders of the ATLAS-project inward which this report was conducted.
Similar studies fifty-fifty farther dorsum inward history would hold upward really difficult, since earlier the arrival of Christianity the deceased were unremarkably cremated, so leaving insufficient fabric for deoxyribonucleic acid analysis.
The findings are published inward Current Biology.
