But where in Scandinavia did Grímur and his followers come from?</p> <p>“Here we provide strong evidence that the Faroe Islands were colonized by a diverse group of male settlers from multiple Scandinavian populations,” said Dr. Christopher Tillquist, a researcher at the University of Louisville.</p> <p>In the study, Dr. Tillquist and his colleagues determined the genotype at 12 ‘short tandem repeat’ (STR) loci on the Y-chromosome of 139 men from the Faroese islands of Borðoy, Streymoy, and Suðuroy.</p> <p>They assigned each man to the most likely haplogroup, each of which has different known distribution across today’s Europe.</p> <p>They compared the distribution of genotypes to those found in 412 men from Norway, Sweden, Denmark, Iceland, and Ireland.</p> <p>This allowed the team to reconstruct the source population of the Viking population founders.</p> <p>Advanced analyses showed that the range of Faroese samples resembled the range of genotypes from broader Scandinavian, whereas the Icelandic genotypes where distinct.</p> <p>The authors also developed a powerful innovative genetic method, called ‘Mutational Distance from Modal Haplotype’ to analyze variation in SNPs (single-nucleotide polymorphisms) within the STRs.</p> <p>This allowed them to reveal a ‘founder effect’ — traces of random loss of diversity during historic colonization by a small number of people — persisting in the genetic make-up of today’s Faroese and Icelandic male populations.</p> <p>“Scientists have long assumed that the Faroe Islands and Iceland were both settled by similar Norse people,” Dr. Tillquist said.</p> <p>“Yet our novel analysis has shown that these islands were founded by men from different gene pools within Scandinavia.”</p> <p>“One group, diverse in their Scandinavian origins, established themselves in the Faroe Islands, while another and more genetically divergent band of Vikings colonized Iceland. They have separate genetic signatures that persist to this day.”</p> <p>“There doesn’t seem to have been any interbreeding afterwards between these two populations, despite their geographic proximity.”</p> <p>“Our results demonstrate that Viking expansion into the North Atlantic was more complex than previously thought.”</p> <p>“Each longship that set sail for these distant islands carried not just Vikings, but distinct genetic legacies.”</p> <p>“We can now trace these separate journeys of conquest and settlement, revealing a more nuanced story of Viking exploration than told by the history books.”</p> <p>The <a href="https://www.frontiersin.org/journals/genetics/articles/10.3389/fgene.2024.1462736/full" target="_blank" rel="noopener">findings</a> appear in the journal <em>Frontiers in Genetics</em>.</p> <p><span style="color: #808080;">_____</span></p> <p><span style="color: #808080;">Allison E.
