Neanderthals and Homo sapiens may have shared a common culture for more than 20,000 years, according to a study published Monday in the Proceedings of the National Academy of Sciences. Excavations at Üçağızlı II Cave in southern Türkiye reveal that both species occupied the site and utilized similar tools, survival strategies, and decorative objects, suggesting a deeper level of interaction than previously recorded in the archaeological record.
How did researchers uncover this cultural connection?
An international research team, including Morimoto, spent five years excavating the Üçağızlı II Cave. Their work identified distinct occupation layers: Neanderthals inhabited the site between approximately 77,000 and 59,000 years ago, followed by H. sapiens between 59,000 and 47,000 years ago. By comparing the stone tools and hunting-gathering remains from these layers, the team identified consistent practices used by both groups. These findings challenge older theories that the two species lived in complete isolation from one another.
Researchers found that both Neanderthals and modern humans collected the same specific type of mollusk shell. Because these shells held no nutritional value, scientists interpret this as evidence of a shared, non-utilitarian, and potentially symbolic cultural preference.
Why do these findings contrast with previous excavations?
Previous archaeological work has yielded conflicting evidence regarding the relationship between the two species. In Mandarin, France, researchers found that H. sapiens and Neanderthals occupied the same areas in alternating phases but showed no signs of cultural exchange. Conversely, findings from the Tinshemet Cave in Israel provided earlier evidence of shared behaviors. The data from the Turkish site adds significant weight to the theory that knowledge and culture flowed between the two groups as they migrated across Eurasia during the “Out of Africa” expansion.
What is the significance of the human fossils in Türkiye?
The human fossils recovered from Üçağızlı II Cave are dated between 50,000 and 60,000 years old. This placement presents two distinct possibilities for evolutionary history, according to the research team. These individuals were either close relatives of the ancestral population that led to all modern non-African humans, or they represented an earlier, previously undocumented migration wave into the Levant. This discovery helps fill a critical gap in the paleontological record concerning the primary corridor used by early humans to expand out of Africa.

Frequently Asked Questions
- Did Neanderthals and humans interbreed? Yes, evidence shows that the two species interbred for thousands of years after H. sapiens arrived in Eurasia.
- Why are the mollusk shells important? Because the shells provided no food, their collection suggests that both species shared an interest in aesthetic or symbolic objects, pointing to a form of cultural communication.
- Where was this evidence found? The evidence was found at the Üçağızlı II Cave site in southern Türkiye.
