45,000-year-old bones shed light on modern humans’ arrival to Northwestern Europe

Instead, the new study shows that the LRJ was made by modern humans. “We know that the LRJ exists right around the time period where modern humans are thought to enter Europe. The new research gives an important perspective as to when and how modern humans reached different parts of Europe. “We do not only associate the LRJ with modern humans, we’re also able to show that their presence in Northwestern Europe is much earlier than previously thought. “I look forward to future studies further detailing the behaviour of these first modern humans on the continent using this exciting combination of cutting-edge methods,” says Frido Welker.

In a cave in Ranis, Germany, an international research team discovered 45,000-year-old bones that they determined to originate from Homo sapiens, modern humans, and different animals such as cave bears, woolly rhinoceros, and reindeer.

The bones were found in an area in Northwestern Europe where archaeologists for decades have recovered stone artefacts characteristic of a technocomplex known as the Lincombian-Ranisian-Jerzmanowician (LRJ). Until now, it was the general belief that this technocomplex was produced by Neanderthals. Instead, the new study shows that the LRJ was made by modern humans.

“We know that the LRJ exists right around the time period where modern humans are thought to enter Europe. Up to this point, we have never known for sure which human population was responsible for making this culture. I am happy we got this resolved,” says Associate Professor Frido Welker, who is one of the authors behind three new studies published in Nature and Nature Ecology & Evolution.

The new research gives an important perspective as to when and how modern humans reached different parts of Europe.

“We do not only associate the LRJ with modern humans, we’re also able to show that their presence in Northwestern Europe is much earlier than previously thought. They are present in Europe during a period of extreme cold,” says Frido Welker.

The research shows that the very cold environmental conditions at Ranis at the time indicate an open steppe landscape, similar to those found in Siberia and northern Scandinavia today.  This finding is interesting because it shows the climatic resilience of these pioneering groups of our species from the first moment, they entered Northwestern Europe.

The human bones were identified with palaeoproteomics

The researchers used the proteins extracted from bone fragments to identify the animal and human remains found in the LRJ layers.

“Palaeoproteomics is a relatively new tool to perform taxonomic identifications of previously unidentifiable skeletal remains recovered from archaeological sites. At Ranis, this enabled us to identify the first human remains associated with the LRJ layers, which were then analysed further with the latest methods in ancient DNA, radiocarbon dating, and stable isotope analysis.” says Ph.D. student Dorothea Mylopotamitaki, a former PUSHH-Marie Sklodowska-Curie Actions Doctoral Fellow at the Collège de France and the Max Planck Institute for Evolutionary Anthropology, and who conducted the palaeoproteomic research at the University of Copenhagen.

Thousands of fragmented bones revealed patterns of site use and human diet

At the site, the researchers recovered thousands of highly fragmented pieces of bone.

“Zooarchaeological analysis shows that the Ranis cave was used intermittently by denning hyaenas, hibernating cave bears, and small groups of humans,” explained zooarchaeologist Geoff Smith from the University of Kent and adds:

“While these humans only used the cave for short periods of time, they consumed meat from a range of animals, including reindeer, woolly rhinoceros, and horses."

The integration of new archaeological data, morphological and proteomic taxonomic identification, DNA analysis, radiocarbon dating, zooarchaeology, and isotope analysis provides a significant milestone in understanding the initial incursions of Homo sapiens into Europe north of the Alps 45,000 years ago, fundamentally changing our perspective on the arrival of the first modern human pioneers in the region.

“I look forward to future studies further detailing the behaviour of these first modern humans on the continent using this exciting combination of cutting-edge methods,” says Frido Welker.
