Scientists discovered ancient human symbols on tools and figurines that are similar to early writing systems. This suggests that humans were recording information long before they developed formal writing.

More than 40,000 years ago, early humans engraved symbols onto tools, figurines, and other objects. Researchers Christian Bentz and Ewa Dutkiewicz analyzed over 3,000 signs carved into 260 Paleolithic artifacts to understand how writing may have evolved.

Their study found that these sequences of signs were not random decorations. Instead, they display levels of complexity and information density similar to proto-cuneiform, the earliest known writing system.

The researchers examined geometric signs across roughly 260 objects using computational analysis. They compared these Paleolithic markings to proto-cuneiform and modern writing systems. Their results showed that these sign sequences have nothing to do with today's writing systems, which represent spoken languages and are characterized by high information density.

In fact, the signs on the archaeological objects were frequently repeated – cross, cross, cross, line, line, line. This type of repetition is different from modern writing systems.

The study suggests that early humans used these symbols to communicate or store information. The researchers believe that this sign system was an early predecessor to writing.

The Swabian Jura region in southwestern Germany has yielded many artifacts with these intentional sign sequences. The researchers are now investigating how early humans encoded information through visual symbols.

Their goal is not to decipher the symbols, which remain undecoded, but to measure their structural properties. By studying how frequently signs appear and how predictable they are within sequences, Bentz compared these Paleolithic markings to proto-cuneiform and modern writing systems.

Why It Matters

Understanding how humans developed writing systems can help us learn more about our own communication methods. This discovery also highlights the ingenuity of early humans in finding ways to record information before formal writing existed.
