Stories from our foremothers: deCODE publishes an unparalleled genetic snapshot of Iceland 1000 years ago
Iceland was mainly settled by Scandinavian men and women from Irealand and Scotland
In a paper published today scientists at deCODE genetics present the results of the largest study of ancient DNA from a single population ever undertaken. Analyzing mitochondrial DNA, which is passed from mother to offspring, from 68 skeletal remains from approximately 1000 years ago, the study provides the most detailed look to date at how a contemporary population differs from that of its ancestors. The results confirm previous deCODE work that used genetics to test the history of Iceland as recorded in the sagas.
