Cave paintings appear at the start of Upper Palaeolithic. These paintings mark the dawn of a newly attained gift of humans to represent three-dimensional features into two-dimensional figures. How did they get this gift, that was not seen in any human species previously?
We have evidence of people (for example in the 18th century Islamic societies), who lived without ever seeing an image of an animal. When shown a picture of the horse, they are unable to comprehend it easily. Understanding of scaled representations of actual things is not something that is built into the human brain. It is a learned craft.
How these humans around 50,000 learn this. Bigger brain size? Humans had large brains for large parts of their history, yet representational art appeared only 40,000 years ago. This creativity happened only in one species of humans.
Homo sapiens sapiens (H. sapiens), is the only surviving human species. Several human species had coexisted with other species since 3 million years - H. habilis, H. erectus, H. rudolfensis, H. gautengensis, H. ergaster, H. antecessor, H. cepranensis, H. heidelbergensis, H. neanderthalensis, H. naledi, H. tsaichangensis, H. rhodesiensis, H. floresiensis, etc. The interesting question is why other species vanished, while H.sapiens survived.
Human species remained without change for a long time. H.sapiens evolved 300,000 years ago (or even probably earlier according to current DNA evidence). Something happened only in H.sapiens, not in other humans, at around 70,000 years. That unique event took place when H.sapiens were still in Africa.
Sometime before this the H.sapiens species were almost on the way to extinction, with the population reduced to some 600 individuals. The change, now called the “Cognitive Revolution”, turned the fortunes of this weak and insignificant species at that time.
Around this period H.sapiens made the second attempt (?) to leave Africa and was quite successful. An earlier known attempt around 100,000 years ago to leave Africa was a disaster. After the second successful attempt in migration, H.sapiens also started dominating other humans. Brain size of H.sapiens was a bit smaller than Neanderthals. H.sapiens were also weak scavengers, not brutal savages as we would like to believe today.
From where did H.sapiens get this power to dominate others human species (as well as other animals)?
Central to this answer is belief. H.sapiens at 70,000 years back got the ability to believe in things that do not exist. Complex language, art, commerce and religion made its appearance. The first figurine known today is from around 40,000 ago, and it a the Lion-man (or Lioness-woman) of the Hohlenstein-Stadel. The ability to believe in things that do not exist in real world became a distinctive character of H.sapiens.
How did this help H.sapiens? This ability to believe gave H.sapiens capacity to form larger groups. Other humans, as wells as other animals, could create only groups up to 20 or 30 individuals. Today, India or China is a group of over 1.2 billion H.sapiens each. The Catholic church is a group of 1.5 billion H.sapiens led by an alpha male. Except that this alpha male does not procreate. He is a shaman.
Larger groups are readily equated with superior physical strength, which is true. However, the real advantage is in an exponential increase in creativity when different brains come close. Today, inventions come from the most populous cities.
However, is this belief based only on imagined things? Is there another reality behind this creative imagination?
Cave art makes its appearance from around 40,000 years. The surprising fact is that cave art has a similarity wherever you go in the world, be it France or Indonesia. Animals and some geometric shapes are carved or painted in caves. Why dark caves? Why only animals, not the landscape, not even realistic humans (only stick people or human-animal figurines are painted).
Importantly, animals seem to float on the walls and ceilings of the caves. In many cases legs are hanging, sometimes even the underside of the hoofs are seen.
James David Lewis-Williams in this book says that cave artists are not making up things. They are not letting their imagination run wild. They are drawing things they “saw”, in their minds, in altered states of consciousness.
This belief makes us what we are today, and they exist in the spectrum of our consciousness.
Cave art could be the evidence for expanded human consciousness. This consciousness can be referred as higher consciousness, that is different from the ordinary awareness. We may call it altered the state of consciousness, but is not something separate from our normal consciousness. We all experience such consciousness when we slowly drift into sleep. We are very much aware of dreams, and there are other stages of consciousness when we move in and out of a deep sleep.
Several psychotropic substances enhance these altered states of consciousness. Other conditions could also be responsible. However, we have several pieces of evidence of psychotropic substance use in ancient religions and also in ethnographic groups of the present.
Cave artists are not making up things. They see reality on rock surfaces. They are making animals appear from the rocks, a reality they have experienced. To the people who made the pictures, they are not images; they are not symbolic representations, but real “beings”.
When you drift into higher states of consciousness, you see and experience a variety of visual images. You also hear, smell and feel many things. Initially, you are choked and constricted; you feel you are falling through a long dark tunnel. Or else you are drowning in waters and feel tremendous pressure on your chest. Then the animals and other "spirits" appear. They help you navigate and assist you to rise to higher levels - into the light.
The cave art also includes many symbols - grids, zig-zags, dots, etc. Do they persist to this date as the cross and swastika? A “wounded man” lies among the ethereal animals, speared. “Crucified man” imagery continues to this age.
Neanderthals, who co-existed with humans for some time and interbred (the book gets this wrong) did not indulge in cave art, even though they occupied some of the same caves at times. In all probability, Neanderthals saw the paintings left by their cousins. They could have been baffled and never made any sense out of the figures.
Cave art ended with the conclusion of the last ice age. History saw the start of a new dawn that ended the hunter-gatherer lifestyle that gave way to cities and settled agriculture. Caves and tunnels did not disappear. They make the appearance as cavernous buildings - pyramids, ziggurats, temples and churches, with paintings covering the walls and ceilings. Another set of animals and half animal - humans images, floating out of the walls. They beckon you to another world.
Geographic patterns persist. Of chanting, singing and dancing we have no evidence from the Upper Palaeolithic, but if “present is key to the past”, we have to conclude that all the religious paraphernalia and beliefs have a long history.
Why belief arose in one animal species has the answer in the higher consciousness that H.sapiens acquired 70,000 years onwards. It has deep relations to dreams, in the sense that dream state consciousness is part of this higher consciousness.
The cave paintings are not graffiti painted by bored individuals or aesthetically inclined artists. They represent part of our consciousness that we all experience, yet not understand well.
Lewis-Williams talks about social stratification and conflicts maybe from a Marxist perspective. I am not sure how relevant this could be. Shamanism does not indicate social stratification. Such rigid social stratification happened after the hunter-gatherer mode of living was abandoned. So these views should be taken cautiously. Otherwise, the book is a good read.
