“Symbolic precursors to writing” — a system of conventional signs — from the Paleolithic?
Below is a guest post by Richard Sproat and Rafael Núñez. It summarizes a recently published paper by d’Errico, Santos da Rosa, Courtenay, Núñez, Liu, Sproat, & Blasi, "Inferring Conventional Sign Systems from Paleolithic Engravings: Methodological and Theoretical Challenges".
Back in February, Christian Bentz and Ewa Dutkiewicz (henceforth BD) published a paper in the Proceedings of the National Academy of Sciences, that presented their study of markings on Paleolithic artifacts, mostly in bone, antler and ivory, from the Swabian Aurignacian (43,000–34,000 BP). Their conclusion, based on various statistical analyses, including entropic measures, and a couple of sign repetition rate measures, was that these marks constituted a structured system of deliberate and conventional signs. By translating the engravings into 1D sequences of standardized characters, they reported strong statistical overlap with early Mesopotamian protocuneiform (Uruk V) and clear divergence from later systems as well as modern writing systems.
