Ancient DNA rewrites Iceland's settler origins

Source: newscientist.com

TL;DR

Ancient DNA from skeletons shows Iceland's first settlers were mostly from Norway, not a mix with Ireland as long thought.
25 skeletons from early graves reveal 75% Norwegian ancestry, challenging the Viking saga of Irish slaves.
This rewrite traces settlement to 870-930 AD, with women mainly from the British Isles.
Discovery upends national origin stories and highlights DNA's power to correct historical myths.

The story at a glance

Ancient DNA analysis has overturned the traditional tale of Iceland's founding, revealing Norwegian dominance over the previously celebrated Irish influence. Scientists reported this on 22 October 2024, driven by new genomic data from early graves.

Key moments & milestones

870 AD: Iceland's settlement begins, per sagas blending Norwegian voyages with Irish captives.
9th-10th centuries: 25 individuals buried in early Icelandic cemeteries provide key DNA samples.
2024: Team led by Ashot Margaryan and Agata Hałuszko publishes findings in Nature, analyzing genomes against modern and ancient references.
Turning point: Evidence shows no substantial Irish paternal lines, only maternal British Isles input.

Signature highlights

Skeletons from three early sites - Nuuk, Kverkar and Hóll - yielded genomes showing 74.7% Norwegian ancestry on average.
Saga hero Ingólfr Arnarson, credited as first settler, now aligns genetically with Norwegian roots, not Irish.
Women settlers hailed from British Isles (Scotland, Ireland), but men were overwhelmingly Scandinavian.
Study debunks "Black Irish" myth, proving limited Irish male contribution despite cultural legends.

Key quotes

"The genetic results do not support the romanticized story of the settlement of Iceland."

- Ashot Margaryan, lead author

"This is a huge change to what we thought."

- Jóhanna Ólafsdóttir, Icelandic geneticist

Why it matters

This revelation reshapes Iceland's origin narrative, emphasizing empirical science over folklore and prompting reevaluation of Viking-era migrations across the North Atlantic. It underscores how ancient DNA can validate or dismantle national myths, influencing heritage debates worldwide. Watch for expanded genomic studies on other saga-linked sites, potentially revealing more about early medieval mobility.
