Prehistoric bone etchings believed to be among oldest evidence of human use of symbols

While scientists and historians have long surmised that etchings on stones and bones have been used as a form of symbolism dating back as early as the Middle Paleolithic period (250,000-45,000 BCE), findings to support that theory are extremely rare.

A recent discovery by archeologists from the Hebrew University and the University of Haifa alongside a team from the Le Centre National de la Recherche Scientifique in France have uncovered evidence of what may be the earliest-known use of symbols. The symbols were found on a in the Ramle region in central Israel and are believed to be approximately 120,000 years old.

Remarkably the fragment remained largely intact and the researchers were able to detect six similar etchings on one side of the , leading them to believe that they were in the possession of something which held symbolic or spiritual significance. The find, which was recently published in the scientific journal Quaternary International, was discovered in a trove of flint tools and exposed at a site during archaeological excavations.

Dr. Yossi Zaidner of the Institute of Archeology at Hebrew University says that the site was likely used as a camp or a meeting place for Paleolithic hunters who would then slaughter the animals they caught at that location. The identified bone is believed to have come from an extinct large wild cattle, a species which was very common in the Middle East at that time.

Using three-dimensional imaging, microscopic methods of analysis and experimental reproduction of engravings in the laboratory, the team was able to identify six different engravings ranging from 38 to 42 millimeters in length. Dr. Iris Groman-Yaroslavski from the University of Haifa explained, "Based on our laboratory analysis and discovery of microscopic elements, we were able to surmise that people in used a sharp tool fashioned from flint rock to make the engravings."

The paper's authors stress that their analysis makes it very clear that the engravings were definitely intentionally man made and could not have been the result of animal butchering activities or natural processes over the millennia. They pointed to the fact that the grooves of the engravings discovered are in a clear U-shape and wide and deep enough that they could not have been made by anything other than humans intent on carving lines into the bone.

The analysis was also able to determine that the work was performed by a right-handed craftsman in a single working session.

Ms. Marion Prévost from the Institute of Archeology at Hebrew University says that every indication was that there was a definite message behind what was carved into the bone. "We reject any assumption that these grooves were some sort of inadvertent doodling. That type of artwork wouldn't have seen this level of attention to detail."

So what was the message behind the six lines in the bone? The authors write, "This engraving is very likely an example of symbolic activity and is the oldest known example of this form of messaging that was used in the Levant. We hypothesize that the choice of this particular bone was related to the status of that animal in that hunting community and is indicative of the spiritual connection that the hunters had with the animals they killed."

Dr. Zaidner said, "It is fair to say that we have discovered one of the oldest symbolic ever found on earth- and certainly the oldest in the Levant. This discovery has very important implications for understanding of how symbolic expression developed in humans. At the same time, while it is still not possible to determine the exact meaning of these symbols we hope that continued research will unveil those key details."
