Code hidden in Stone Age art may be the root of human writing

NewScientist – A painstaking investigation of Europe\u2019s cave art has revealed 32 shapes and lines that crop up again and again and could be the world’s oldest: “A painstaking investigation of Europe’s cave art has revealed 32 shapes and lines that crop up again and again and could be the world’s oldest code: “…Von Petzinger, a palaeoanthropologist from the University of Victoria in Canada, is spearheading an unusual study of cave art. Her interest lies not in the breathtaking paintings of bulls, horses and bison that usually spring to mind, but in the smaller, geometric symbols frequently found alongside them. Her work has convinced her that far from being random doodles, the simple shapes represent a fundamental shift in our ancestors’ mental skills. The first formal writing system that we know of is the 5000-year-old cuneiform script of the ancient city of Uruk in what is now Iraq. But it and other systems like it – such as Egyptian hieroglyphs – are complex and didn’t emerge from a vacuum. There must have been an earlier time when people first started playing with simple abstract signs. For years, von Petzinger has wondered if the circles, triangles and squiggles that humans began leaving on cave walls 40,000 years ago represent that special time in our history – the creation of the first human code. Between 2013 and 2014, von Petzinger visited 52 caves in France, Spain, Italy and Portugal. The symbols she found ranged from dots, lines, triangles, squares and zigzags to more complex forms like ladder shapes, hand stencils, something called a tectiform that looks a bit like a post with a roof, and feather shapes called penniforms. In some places, the signs were part of bigger paintings. Elsewhere, they were on their own, like the row of bell shapes found in El Castillo in northern Spain or the panel of 15 penniforms in Santian, also in Spain.

Perhaps the most startling finding was how few signs there were – just 32 in all of Europe. For tens of thousands of years, our ancestors seem to have been curiously consistent with the symbols they used. This, if nothing else, suggests that the markings had some sort of significance. “Of course they mean something,” says French prehistorian Jean Clottes. “They didn’t do it for fun.” The multiple repetitions of the P-shaped claviform sign in France’s Niaux cave “can’t be a coincidence”, he argues…”
