Paleoanthropologist Genevieve von Petzinger is entranced by the engraved signs and symbols found in caves all over the world. She has spent years researching this ancient visual communication and in her 2015 TED Talk, Why are these 32 symbols found in ancient caves all over Europe?, von Petzinger shares what she’s learned.
Her research catalogs the first ever collection of 32 signs and, stunningly, tracks the same symbols across countries throughout a 30,000 year period starting with the ice age.
Mikey and Molly analyze Genevieve’s presentation and reflect on the evolution of what “Presentation Thinking” is all about—visual communication and storytelling.
