Paleogeneticists sequenced the DNA of about 250 individuals buried in the territory of modern-day Spain between the 2nd and 8th centuries AD. Thanks to these studies, scientists were able to trace changes in the genetic landscape of the Iberian Peninsula during the periods of Roman rule and the Migration Period.
During the work, an important discovery was made: a brother and sister belonging to the ancient Germanic elite were found. These relatives were buried approximately 700 kilometers apart, which corresponds to a walking journey of about 22 days.
The results of this study were presented in a scientific publication published in the journal Cell.
