The genomic history of the Iberian Peninsula reconstructed

  • The findings, published in ‘Science’, show an invasion of steppe descendants who replaced almost all men 4,000 years ago.
  • The study reveals that the current Basque population presents typical genetics of Iron Age Iberia.

An international study co-led by researchers from the Spanish National Research Council (CSIC) at the Institute of Evolutionary Biology (IBE) and Harvard University (USA) has developed a genetic map of the Iberian Peninsula covering the last 8,000 years.

Published in the journal Science, it analysed the genomes of 271 inhabitants of the peninsula from different historical periods and has contrasted them with data collected in previous studies of 1,107 ancient and 2,862 modern subjects. The results show an unprecedented image of the transformation of the Iberian population along different historical and prehistoric stages.
