Ostrich shell art in South Africa 60,000 years ago

There’s a new paper in PNAS reviewing the tradition of etching on ostrich shells. Since it’s PNAS, the paper isn’t on the website, but Edward Edmund Yong is able to cover the major points thanks to his access. This stuff is of interest because there was a long time lag between the emergence of anatomically modern humans in Africa, and their subsequent expansion out of Africa ~50,000 years ago, the crystallization of “behavioral modernity.”
