Mitochondrial DNA from eight fossils found in Stajnia Cave, Poland, sheds light on a close-knit group of Neanderthals who lived around 100,000 years ago. This discovery offers a rare glimpse into the lives of a single community in prehistoric Europe.
Stajnia Cave is located in southern Poland, nestled among limestone formations. Between 2007 and 2010, researchers dug in a specific area of the cave, uncovering nine human teeth, five of which were identified as Neanderthal.
In a recent study, a team led by Professor Andrea Picin from the University of Bologna analyzed mtDNA from these teeth. They concluded that the fossils belonged to at least seven to eight Neanderthals. Notably, three specimens showed identical mtDNA, indicating they were likely from the same family or closely related.
The DNA analysis revealed that these individuals thrived during a warm period, roughly between 120,000 and 92,500 years ago. This makes this group the oldest known cluster of Neanderthals linked through genetic evidence in Central Europe. Professor Picin emphasized that this is the first time researchers can observe a specific group of Neanderthals from this region.
Dr. Wioletta Nowaczewska and Dr. Adam Nadachowski acknowledged the significance of this find for both Polish research and the broader understanding of Neanderthals in Europe. They highlighted that it offers a coherent genetic picture of these ancient humans, contrasting with past studies that usually focus on single or scattered fossils.
Interestingly, researchers found that Neanderthals with similar genetic markers lived as far apart as southeastern France and the Iberian Peninsula. This suggests that this maternal lineage spread across Europe before being replaced by later populations.
Dr. Mateja Hajdinjak from the Max Planck Institute noted that two juvenile teeth shared the same mtDNA as an adult, indicating a close family relationship among these individuals.
A comparison with another Neanderthal named Thorin, discovered in France, showed striking similarities in mtDNA despite being dated to about 50,000 years ago. This suggests that chronological dating must be approached cautiously, as highlighted by Professor Sahra Talamo. The interplay between archaeology, radiocarbon dating, and genetics is crucial for accurate historical understanding.
This study not only enhances our knowledge of Neanderthals but also shows how interconnected ancient populations were. As we uncover more genetic evidence, we get a clearer picture of our prehistoric relatives and their diverse communities.
