At Blombos Cave, 200 miles east of Cape Town, South Africa, Christopher S. Henshilwood, of the University of Bergen in Norway and the University of Witwatersrand in Johannesburg, and a team of researchers from Australia, France, Norway and South Africa discovered the earliest paint workshop in 2008. The site contained the tools and ingredients with which early modern humans most probably mixed some of the first known paint. Accurate dating of the material, and publication of the results did not occur until October 2011. Much of the analysis and dating of the material was directed by Francesco d’Errico of the University of Bordeaux in France.
"These cave artisans had stones for pounding and grinding colorful dirt enriched with a kind of iron oxide to a powder, known as ocher. This was blended with the binding fat of mammal-bone marrow and a dash of charcoal. Traces of ocher were left on the tools, and samples of the reddish compound were collected in large abalone shells, where the paint was liquefied, stirred and scooped out with a bone spatula.
"In the workshop remains, archaeologists said they were seeing the earliest example yet of how emergent Homo sapiens processed ocher, one of the species’ first pigments in wide use, its red color apparently rich in symbolic significance. The early humans may have applied the concoction to their skin for protection or simply decoration, experts suggested. Perhaps it was their way of making social and artistic statements on their bodies or their artifacts.
"Of special importance to the scientists who made the discovery, the ocher workshop showed that early humans, whose anatomy was modern, had also begun thinking like us. In a report published online on Thursday in the journal Science, the researchers called this evidence of early conceptual abilities 'a benchmark in the evolution of complex human cognition.'
