40,000-year-old Stone Age symbols may have paved the way for writing, long before Mesopotamia

Over 40,000 years ago, our early ancestors were already carving signs into tools and sculptures. According to a new analysis by linguist Christian Bentz at Saarland University and archaeologist Ewa Dutkiewicz at the Museum für Vor- und Frühgeschichte (Museum of Prehistory and Early History) in Berlin, these sign sequences have the same level of complexity and information density as the earliest proto-cuneiform script that emerged tens of thousands of years later, around 3,000 B.C.E.
