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.

Etologic horse study from cave at Chauvet

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…

Kate Wong brings us up-to-date on the latest research into the Neandertals in this month’s issue of Scientific American.

I’ve always been fascinated by ‘Neandertal Man’ as he/she used to be called. We think about what it would be like to meet aliens. (Well, I think about what it would be like to meet aliens!) Would we be able to communicate? Would we be able to understand each other? Yet here in our own back yard, in Europe and the Near East and much of Asia, modern human beings were living side-by-side with another hominid form, meeting and presumably trying to communicate, only 30,000 years ago. I refrained from saying ‘another human species’ because the great and still unresolved question is whether we belonged to distinct species, and whether or not modern humans and Neandertals could interbreed. And despite the theories about genocide (by humans), climate change, and diet – we still don’t know why they became extinct about 28,000 years ago.

Grottes de Lascaux II by davidmartinpro.It seems that they had jewellery and bone tools and made sophisticated weapons; but modern human beings had the edge – in their social organisation, in the efficiency of their physique, and in their sheer intelligence and creativity. ‘The boundary between Neandertals and moderns has gotten fuzzier’, writes Christopher B. Stringer – but there is still a boundary. There is something radical and new about human intelligence, a leap and not just a lurch, that gives rise to art, creativity, sophisticated language, morality, and some more reflective kind of self-consciousness. And, interestingly, one of the key markers for paleoanthropologists is the emergence for the first time among human beings of symbolic customs surrounding the burial of the dead. Human intelligence seems to go hand in hand with an appreciation of the significance of death.

Neandertals, we presume, in some way asked questions about how to live; human beings, as far as we can tell, are the only creatures to ask questions about the meaning of that living, and the possibility of living beyond death.

[A wonderful book that first got me interested in human uniqueness in relation to Neandertals is Becoming Human by Ian Tattersall, OUP 1998. It’s probably a bit old now, but it is still in print]
