In just over 1,000 years, Icelanders have gone through numerous changes in their gene pool, to the extent that Iceland's first settlers, who came to the island from Norway and the British and Irish isles between the years 870 and 930, are much more similar to the inhabitants of their original home countries than to Iceland's present-day inhabitants.

This is one of the main conclusions of a study carried out by an international team of scientists which included members of the Spanish National Research Council (CSIC). For the first time, the researchers, whose results are published in the journal Science, analysed the ancient genomes of 25 individuals who lived in Iceland during the colonisation of the island.

With a population of 330,000, Iceland is a country with its own peculiarities. Genes are no exception: isolation and inbreeding throughout its history make this northern Atlantic island a paradise for genetic studies.
