Discovery Reveals Intentional Engravings on 100,000-Year-Old Stone Tools, Suggesting Symbolic Thinking and Creativity Among Early Humans
Subtle marks on ancient stone tools may be more than just simple functional cuts. They could be the key to understanding the earliest signs of abstract and symbolic thinking among our ancestors.
A recent study led by archaeologists from the Hebrew University of Jerusalem in Israel revealed that several stone tools made between 50,000 and 100,000 years ago in the Levant region contain geometric engravings that are not accidental, but rather intentional.
The Levant Region and Its First Inhabitants
The Levant, a region that includes a modern land bridge between Africa and Eurasia, was one of the first stops for our ancestors during their migration out of Africa.

Astronomers find a “backward” solar system that ignores all the rules of space and leaves scientists scratching their heads!
For millennia, this area was crucial for the advancement of early human tools. However, the study of objects found in the area reveals that, beyond functionality, there may be a deeper layer of meaning.
A New Perspective on the Engravings
Under advanced criteria, researchers observed that some of these stone tools, especially those made using the Levallois flaking technique, show evident geometric marks.
Previously, these marks were interpreted only as cutting marks or visual patterns. However, Goder-Goldberger’s team believes that these engravings are more than mere decorations.
These tools, made of flint, have sharp lines and geometric patterns that appear to have been deliberately drawn.
For the researchers, this indicates a more advanced capacity for planning and symbolic expression.
The engravings are not simple marks of use, as they were previously thought. On the contrary, they are signs of more complex thinking.
Technology and Intent in Engravings
The study focused on two stone artifacts, one dated to approximately 100,000 years ago and another from the Middle Paleolithic.
Both feature geometric patterns on their surfaces, showing that the engravings were made before the tool’s completion, not as a simple detail after its use.
The marks are organized in specific areas of stone, demonstrating a clear intent on the part of the makers.
Additionally, another artifact found, a plaque made about 54,000 years ago, also features similar geometric patterns, reinforcing the idea that these engravings were not accidental.
According to Goder-Goldberger, this marking technique reveals an “intention and creativity” of its producers.
Symbolism and Human Behavior
These discoveries shed light on the symbolic capacity of our ancestors. Such patterns can be compared to other symbolic artifacts from the time, like ornamental shells or pigments, indicating a transition from pure utility to a form of visual expression.
For Mae Goder-Goldberger, abstract and symbolic thinking was the foundation of human cognitive evolution. She believes that these engravings may reflect this newly developed ability.
Challenging Traditional Interpretation
Instead of being seen merely as “proto-aesthetic,” or marks made solely for visual pleasure, the engravings on these stone tools suggest something deeper: a connection to the earliest forms of symbolic expression.
Archaeologist João Marreiros from Germany also notes that this research offers a new approach to analyzing Middle Paleolithic artifacts, providing archaeology with a clearer framework for understanding ancient societies.
The study was published in the journal Archaeological and Anthropological Sciences.
