Revised Timeline of Homo Sapiens' Migration into Europe
Written on
Chapter 1: The Arrival of Early Humans
Homo sapiens made their way to northwestern Europe over 47,000 years ago, arriving in this frigid region long before Neanderthals vanished. This pivotal moment in human history occurred several millennia prior to the extinction of their distant relatives.
In three significant research papers, scientists examined fossils unearthed from the Ranis-Ilsenhöhle cave in Germany. Surprisingly, stone tools once attributed to Neanderthals were actually crafted by early Homo sapiens. This revelation dramatically reshapes our comprehension of this era.
Modern humans coexisted with Neanderthals in northwestern Europe for several thousand years, and although evidence suggests they interbred, the extent to which Homo sapiens influenced the extinction of Homo neanderthalensis remains unclear.
Section 1.1: Research Discoveries at Ranis Cave
An international team of researchers has been re-evaluating the archaeological site at Ranis cave in recent years, comprising experts from notable institutions like the Max Planck Institute for Evolutionary Anthropology in Leipzig and others. Their goal was to uncover deeper layers of the site that had been overlooked in the 1930s. Their efforts proved fruitful, revealing thousands of bone fragments buried about 8 meters deep.
“Analysis indicated that the Ranis cave was intermittently occupied by humans, hyenas, and bears,” explains Geoff Smith, one of the researchers. “Despite sporadic human presence, they regularly hunted various animals such as reindeer, woolly rhinoceroses, and horses,” he adds.
The remarkable preservation of the bones allowed for cutting-edge techniques in proteomics and genetics to be applied. Paleoproteomics, a burgeoning archaeological discipline, focuses on the study of preserved proteins in fossilized remains. Previously thought to degrade too quickly for recovery, advancements in chemical and biomolecular analyses now make it possible to identify fossilized proteins. In the case of Ranis, these methods confirmed the presence of Homo sapiens remains, which were further analyzed through DNA testing and radiocarbon dating.
Subsection 1.1.1: Insights from Historical Bones
The team also scrutinized bone fragments housed in the State Office for Heritage Management and Archaeology in Saxony-Anhalt, Germany, focusing on finds from the 1930s to identify human remains. This endeavor was successful, yielding 13 fragments belonging to Homo sapiens.
“Interestingly, several fragments shared identical mitochondrial DNA sequences, suggesting they came from the same individual or closely related individuals,” notes Elena Zavala from the Max Planck Institute for Evolutionary Anthropology. To establish when these humans occupied the cave, radiocarbon dating was employed, measuring the ratios of various carbon isotopes. The findings indicate that these individuals were among the earliest Homo sapiens in Europe, existing as far back as 47,500 years ago. The dating of animal bones showing human modifications corroborated these results.
Moving forward, isotope analysis provided a glimpse into the climatic conditions that these early Homo sapiens faced in the Ranis region. The research demonstrated that they encountered a harsh, cold continental climate with open steppe landscapes, akin to modern-day Siberia or northern Scandinavia.
“Recent beliefs posited that adaptation to cold environments emerged several millennia later. This finding is both fascinating and unexpected,” remarks Sarah Pederzani, a co-author of the studies.
Chapter 2: A New Understanding of Prehistoric Humans
This extensive study, which integrates archaeology, zooarchaeology, genetics, and proteomics, marks a significant advancement in our understanding of Homo sapiens' origins in northern Europe. It was revealed that these early humans thrived in severely cold climates, moving in small groups alongside formidable predators like hyenas and bears. They created sophisticated stone tools shaped like leaves, previously thought to date back to around 43,000 years ago but now recognized as being used much earlier. The outcomes of the Ranis investigations fundamentally alter our timeline and understanding of settlement in Europe north of the Alps.

The video titled "The complex evolution of homo sapiens - 1,000,000 to 30,000 years ago" further explores the evolutionary journey of our species, providing context to these archaeological discoveries.
