You know about my love of prehistoric cave paintings. The famous images at Chauvet were painted over 30,000 years ago – quite a distance in time. This makes it all the more astonishing that painting kits used about 100,000 years ago have been discovered in a cave in South Africa, evidence not just of the production of art and the presence of a symbolic imagination, but also of an ability to mix chemicals and store materials.

This is the abstract describing the research in Science.

The conceptual ability to source, combine, and store substances that enhance technology or social practices represents a benchmark in the evolution of complex human cognition. Excavations in 2008 at Blombos Cave, South Africa, revealed a processing workshop where a liquefied ochre-rich mixture was produced and stored in two Haliotis midae (abalone) shells 100,000 years ago. Ochre, bone, charcoal, grindstones, and hammerstones form a composite part of this production toolkit. The application of the mixture is unknown, but possibilities include decoration and skin protection.

Ian Sample comments:

Two sets of implements for preparing red and yellow ochres to decorate animal skins, body parts or perhaps cave walls were excavated at the Blombos cave on the Southern Cape near the Indian Ocean.

The stone and bone tools for crushing, mixing and applying the pigments were uncovered alongside the shells of giant sea snails that had been used as primitive mixing pots. The snails are indigenous to South African waters.

“This is the first known instance for deliberate planning, production and curation of a compound,” Christopher Henshilwood at the University of Bergen told Science, adding that the finding also marked the first known use of containers. “It’s early chemistry. It casts a whole new light on early Homo sapiens and tells us they were probably a lot more intelligent than we think, and capable of carrying out quite sophisticated acts at least 40,000 to 50,000 years before any other known example of this kind of basic chemistry,” he added.

“You could use this type of mixture to prepare animal skins, to put on as body paint, or to paint on the walls of the cave, but it is difficult to be sure how it was used,” said Francesco d’Errico, a study co-author at the University of Bordeaux. “The discovery is a paradox because we now know much better how the pigment was made than what it is used for.”

So we were there, we Homo sapiens, 100,000 years ago – imagining, thinking, planning, cooperating, collecting, mixing, experimenting, storing, painting; and whatever else this painting led into…
