Texier says that the sheer number is “exceptional in prehistory”. Their unprecedented diversity and etched patterns provide some of the best evidence yet for a prehistoric artistic tradition. While previous digs have thrown up piecemeal examples of symbolic art, Texier’s finds allow him to compare patterns across individual pieces, to get a feel of the entire movement, rather than the work of an individual.
Back to Science News: Researchers already knew that the Howiesons Poort culture, which engraved the eggshells, engaged in other symbolic practices, such as engraving designs into pieces of pigment, that were considered to have been crucial advances in human behavioral evolution. But the Diepkloof finds represent the first archaeological sample large enough to demonstrate that Stone Age people created design traditions, at least in their engravings, Texier says.
