Ancient DNA Research Shines Spotlight on Iberia
Harvard Medical SchoolAn international team led by researchers at Harvard Medical School and the Institute of Evolutionary Biology in Spain has conducted the largest-ever study of ancient DNA from the Iberian Peninsula (modern-day Spain and Portugal), spanning 8,000 years. Analyses suggest the Iberian Y chromosome was almost completely replaced between 4,000 and 4,500 years ago. Findings provide the first opportunity to compare ancient Iberian genomic information to historical records.
