Poland's Stajnia Cave Yields Oldest Genetic Snapshot of a Neanderthal Group

By Published

Scientists analyzed mitochondrial DNA from eight Neanderthal teeth found in Stajnia Cave, Poland, dating back approximately 100,000 years. This data represents a coherent family group, revealing close maternal relationships among at least seven Neanderthals who lived during a warm period between 120,000 and 92,500 years ago. The mitochondrial lineage connects these Neanderthals with populations from the Iberian Peninsula, southeastern France, and the northern Caucasus, indicating widespread migration and genetic exchange. The discovery highlights Central-Eastern Europe's crucial role as a corridor for Neanderthal population movement, challenging previous assumptions about its peripheral status in Neanderthal history.

Key Facts

  • Location: Stajnia Cave, southern Poland, north of the Carpathian Mountains
  • Age: Approximately 100,000 years ago, estimated between 120,000 and 92,500 years ago during a warm period
  • Specimens: Eight Neanderthal teeth analyzed, belonging to at least seven individuals
  • Genetic Material: Mitochondrial DNA extracted and sequenced
  • Family Relationships: Identical mtDNA found in two juvenile and one adult individual, suggesting close maternal kinship
  • Broader Genetic Links: The mtDNA lineage matches Neanderthals from the Iberian Peninsula, southeastern France, and northern Caucasus
  • Research Team Lead: Professor Andrea Picin, University of Bologna

Background & Context

Neanderthals inhabited Europe and parts of western Asia approximately 400,000 to 40,000 years ago. Genetic studies usually rely on isolated fossils from various sites and time periods, limiting understanding of familial or group-level structures. The excavation at Stajnia Cave, conducted from 2007 to 2010, uncovered rare evidence from a single site and time frame, allowing researchers to reconstruct a multi-individual mitochondrial genetic profile. This provides new insights into Neanderthal social organization, maternal lineage distribution, and migration patterns during the Middle Paleolithic period.

Why This Matters for Exams

This study offers important details about Neanderthal genetic diversity, social structures, and their population dynamics in Central-Eastern Europe. It challenges prior perceptions of the region as peripheral, portraying it instead as a key corridor for population movements. Candidates studying archaeology, anthropology, human evolution, or ancient DNA should recognize the significance of mitochondrial DNA analysis in tracing maternal lineages, the relevance of Stajnia Cave as a primacy site for Neanderthal group genetics, and the broader implications for understanding European prehistoric populations.

Points to Remember

  • Stajnia Cave is located in southern Poland at 359 meters elevation in the Kraków-Częstochowa Upland.
  • At least seven Neanderthal individuals, ranging from juveniles to adults, lived at the site in the same period approximately 100,000 years ago.
  • Mitochondrial DNA, inherited maternally, reveals close kinship ties among some individuals, highlighting small, related groups rather than scattered remains.
  • The identified mtDNA lineage was once widespread across western Eurasia before later being replaced by different Neanderthal genetic populations.
  • The results underscore the role of Central-Eastern Europe as a critical corridor for Neanderthal migration, biological exchange, and the diffusion of technology during the Middle Paleolithic.
  • This research demonstrates the importance of integrating archaeological context, careful radiocarbon dating, and genetic evidence to reconstruct early human history accurately.
  • The findings were published in 2026 in the journal Current Biology, led by the University of Bologna's Andrea Picin.
