Genevieve von Petzinger, a paleoanthropologist, has a TED talk that is garnering some attention. She speaks on her findings from the exploration of art and geometric signs in caves around Europe. Most people have long known about the cave art, but the geometric signs were largely ignored until von Petzinger decided to focus on them and catalogue them.
Maybe fascination with the art distracted people from the significance of the geometric signs. Whatever the reason, Von Petzinger is the first person to document and create a database of those geometric signs. She reports previously undocumented geometric signs in 70% of the caves she surveyed.
Her TED talk focused on a stunning discovery. She found only 32 different geometric signs in all the caves she visited. Thus, only 32 different geometric signs were developed over a 30,000-year span on the entire continent of Europe!
“What’s the big deal?”, you might ask. The answer is that we would expect much more variation if they were random doodles or decorations. The fact that the same signs were used over and over again suggests something more than mere art.
The signs were repeated from location to location. About 60% of the signs were used throughout the entire 30,000-year time span. Some signs appeared early and ceased to be used. Other signs appeared later. Some signs appeared in wide geographic distribution, while other signs appeared in more concentrated geographic areas. But most of the signs were found throughout the continent and throughout the 30,000-year span.
Another interesting observation is that cave art in Europe bears some resemblance to cave art as far away as Indonesia and Australia. Many of the same signs appear in far flung places, especially in the same 30,000-40,000 year range. Genevieve von Petzinger believes these findings indicate an increasing likelihood that “this invention traces back to a common point of origin in Africa”.
“[T]hat is a subject for a future talk”, says von Petzinger. Meanwhile, let’s explore the significance of the geometric signs found in the European caves
