Ancient DNA studies reveal complex migration patterns in Europe

New genetic research is providing deeper insights into the ancestral movements that shaped Europe. A study led by the University of Vienna, published in Science Advances, analyzed the DNA of a woman who lived near the Pyrenees approximately 30,000 years ago. Her genome reveals a connection between western and eastern European populations during the Gravettian period, suggesting that long-distance genetic exchange occurred without replacing existing regional ancestries during the Last Glacial Maximum.

In a separate investigation published in the journal Cell, researchers examined the demographic impacts of Roman rule and early medieval migrations in the Iberian Peninsula. By analyzing DNA from 243 individuals who lived between 100 and 800 CE, the study found that Roman expansion introduced ancestry from the eastern Mediterranean and North Africa. While later migrations brought Central-Northern European-related ancestry, the demographic shifts during the Roman era were more pronounced than those during subsequent medieval migration periods.
