Paleogeneticists sequencing genomes from the Gravettian culture have discovered that Ice Age Europeans maintained genetic connections across long distances, according to archaeologymag.com.
New Study Challenges Genetic Divide in Gravettian Culture
Archaeologists have long tracked the Gravettian culture through tools, dwellings, and artifacts like tanged arrowheads and mammoth ivory Venus figurines. Yet, while the culture spanned a wide swath of Europe, researchers previously identified two distinct genetic groups within it. One cluster inhabited western Europe, while another populated central and eastern Europe. A new study published in Science Advances challenges that rigid separation.
A team of paleogeneticists extracted DNA from several Gravettian individuals and sequenced their genomes. Among them was a woman who lived in Isturitz Cave in southwestern France near the Spanish border. Her remains yielded the oldest complete genome discovered in that specific region to date. While most of her genetic sequences matched western European lineages, she also carried distinct genetic signatures from central and eastern Europe. Genetic modeling applied by the research team revealed a pulse of gene flow moving from east to west approximately 32,500 to 31,500 years ago.
Contrasting Findings at Ormesson
The genetic patterns found in southwestern France find a parallel in other regional excavations. Nautilus reported that genetic data recovered from another Gravettian individual who lived in Ormesson, France, aligns with the Isturitz findings. This geographic distribution suggests that southern France functioned as a dynamic hub of Gravettian activity. Prehistoric populations met, mingled, and mated across vast continental expanses rather than remaining isolated in regional pockets.
Pere Gelabert of the University of Vienna explained the significance of these findings in a public statement. He noted that eastern and western European populations were not as genetically isolated as previously assumed, and that gene flow across such large distances adds a new dimension to our understanding of how Gravettian populations connected.

| Western Europe | Isturitz Cave (France) | Western European | Central and Eastern European |
| Western Europe | Ormesson (France) | Western European | Central and Eastern European |
Unresolved Questions in Prehistoric Migration
Despite the clarity provided by genomic sequencing, the exact social mechanisms driving this long-distance gene flow remain unmapped. Researchers have established the timing of the east-to-west genetic pulse between 32,500 and 31,500 years ago, but the precise seasonal routes, social networks, or exchange systems that allowed ancient hunter-gatherers to maintain contact across thousands of kilometers are not yet known.
