The research team revisited a hip bone, known as an ilium, excavated from the cave years ago. This bone, found to be from a newborn baby, presented a remarkable discovery. It did not match the characteristics of either Neanderthal or AMH species.
In a cave in France that holds layers of prehistoric significance, a team of international anthropologists has uncovered a bone that may reveal an entirely unknown lineage of Homo sapiens. This fascinating find, bringing forth new insights into the evolution of our species, has sent ripples through the scientific community since it is the first evidence of a new lineage of Homo sapiens.
Located in France, the Grotte du Renne cave has been a focal point for archaeological exploration for decades. Its various layers provide a snapshot into different time periods, with the deepest parts showcasing the era of the Neanderthals and higher layers reflecting when anatomically modern humans (AMHs) made the cave their home.
A Layer of Coexistence
Interestingly, there’s a layer sandwiched between the Neanderthals and AMHs that represents a time when the two hominids might have lived together. The tools found in this layer belong to the early Châtelperronian techno-cultural complex. However, scientists have long debated whether Neanderthals, AMH, or both were responsible for these tools.

A New Lineage of Homo Sapiens?
By contrasting the ilium with Neanderthal and modern baby bones, the scientists concluded that its unique shape suggests a previously unknown lineage of Homo sapiens with a morphology slightly divergent from AMH. This revelation has ignited discussions and prompted further inquiries into human evolution.
The researchers also proposed that the tools from the Châtelperronian complex might be the result of diffusion. In this scenario, AMHs would have crafted the tools, with Neanderthals replicating and possibly adapting them to fit their specific needs. This adaptation reflects the potential hybridization that might have existed in parts of Europe when Neanderthals and AMHs coexisted.
Conclusion
The discovery of a possible new lineage of Homo sapiens in the Grotte du Renne cave is more than just a significant archaeological find. It opens up new pathways of understanding into the intricate history of human evolution, shedding light on a period when two distinct hominids may have shared knowledge and tools. As the studies continue, the mystery deepens, and the quest for answers promises to be an enthralling journey.
