A groundbreaking study has revealed that artifacts dated to 40,000 years ago may represent a lost chapter in the history of human communication, suggesting that early European hunter-gatherers employed an advanced system of signs for information transmission. This revelation challenges conventional timelines about the development of sign systems and human cognitive abilities. The research was conducted by linguist Christian Bentz from Saarland University and archaeologist Ewa Dutkiewicz from the State Museums of Berlin, who published their findings in the Proceedings of the National Academy of Sciences (PNAS).

The implications of this find are profound, as it pushes back the origins of systematic communication long before the advent of written language. It raises questions about the cognitive and cultural development of early human societies, suggesting that the ability to communicate using symbols may have been a significant aspect of social organization among prehistoric communities. The study indicates a greater complexity in the communication abilities of our ancestors, who were likely using a form of symbolic language to convey meaning among themselves.

This discovery not only sheds light on our past but also provides insight into the evolutionary journey of human communication, highlighting the sophistication of sign usage among prehistoric peoples. As more evidence emerges, our understanding of the cognitive capabilities of early humans continues to evolve, paving the way for further exploration into how language and communication developed over millennia.
