Cro-Magnon Brain Capacity
Extract of the book: Dawn of the Lost Civilisation (Brain capacity (Cro-Magnon Man))
At roughly 3.2 billion base pairs, the Neanderthal genome is about the size of the modern human genome. According to preliminary sequence data, 99.84% of base pairs in the modern human and Neanderthal genomes are identical, compared with humans sharing around 94% of base pairs with chimpanzees. The researchers recovered ancient Neanderthal DNA by extracting it from the femurs of three 38,000-year-old female Neanderthal specimens from Vindija Cave, Croatia, and from other bones found in Spain, Russia, and Germany. The project faced many difficulties, including contamination of the samples by bacteria that had colonised the Neanderthal’s body, and by humans who handled the bones at the excavation site and in the laboratory. So, we must be realistic about the outcomes and acknowledge that future samples may vary in investigations into Cro-Magnon man’s ancestors.
Another comparison is in the cranial capacities of this species. Within the human population, studies have examined whether brain size is related to various cognitive measures. Early anthropologists and psychometricians found these correlations, and even modern studies (which began with Van Valen 1974) have suggested similar correlations, including Jensen & Johnson 1994 in ‘Race and Sex differences in Head Size and IQ’. They wrote
“In all of the 25 independent studies we have found in the literature, nonzero positive correlations between head measurements and intelligence measurements to be found, all but five with correlations significant beyond the 0.5 confidence level. The average correlation between various external head size and IQ is close to 0.15. But external head size is rather weak proxy for brain size. Two recent studies have measured brain size per se by means of magnetic resonance imaging (MRI) and found correlations with IQ in the 0.3 to 0.4 range (Andreasen et al.,1993 Willerman, Schulz, Rutledge, & Bigler, 1991).”
Therefore, just how intelligent was Homo Superior in comparison to other groups and us in prehistory?
Today’s human Brain (Modern Man) is on average 1380cm3, while Homo sapiens’ brain averaged 1660cm3, so they are (on average) 20% more intelligent than us. On the IQ scale, that would mean that ‘Modern Man’ has an IQ of between 90 and 110 points (Stanford–Binet Intelligence Scale). While Homo Superior would have an IQ between 108 and 132 (classified as High Average to Superior, held by the top 7% of the present population) – hence my new Homo Superior (Cro-Magnon man) classification.
We can see the same correlation in other animals, such as the size of Wolfs and Dogs – the dog’s brain is a deterioration of the animal it used to be in the wild. It does not mean that they are stupid, or their lives are poor; in fact, one would suggest (if you were a dog) that their lives today are much more progressive than the life they once lived. But if man were wiped out by disease tomorrow, how many dogs would survive in the long term? It would not be beyond thinking that dogs would become extinct without humans to look after them?
Can we not use the same analogy for Modern Man compared to Homo sapiens (Cro-Magnon man)?
For if the sun’s electromagnetic radiation increased through our Van Allen magnetic belt that surrounds the earth, our power stations would go into ‘meltdown’ and would work no longer, leaving the world without electricity – how many ‘modern day’ advanced, sophisticated and cultured people would survive, long term, without electricity, gas and petrol?
Dogs need humans to help them survive their ‘luxury’ lifestyles, and humans need technology for the same reason. Wolves and Homo Superiors (Cro-Magnon man) are naturally ‘wild’ animals of superior intelligence that allow them to adapt to ‘any’ environment and not to simply survive but, moreover, grow and thrive within the environment, without fear of extinction. Another interesting comparison between brain capacity and IQ is that the further north you travel, the higher a species’ IQ. This includes both man and wolf. Given this fact, we have to consider the reasons for this occurrence. Is this growth a product of the environment and weather, or does the higher intelligence allow a species to travel further, as its adaptability can overcome the environment better than someone with a lesser capacity?
In our last chapter, we theorised that the last Homo migration ‘Out of Africa’ by Sapiens 50,000 years ago, led to an exodus from southern Asia about 30,000 years ago to Europe as a consequence of multiple mutations. This interbreeding brought an unknown kind of humanoid – Homo Superior. With a new kind of thinking as they had much larger brains with immense IQ, thus allowing them to move to fresh and greener pastures, following the ample food supply through their natural migration patterns. This increase in food allowed for an increased brain capacity, and the growth of imagination led them to develop and create brand new forms of transportation, allowing them and their families to travel faster and for longer than before, through dangerous forests full of deadly animals.
For a species that had a natural ability to both swim and walk on land, with the vast waterways that spread across Palaeolithic Europe for thousands of miles in all directions (let alone the sea routes within sight of the shoreline), the boat would have been the method of choice. The environment was full of marshlands, lakes and forests from the last ice age, and water reeds would have grown in abundance. The simplest way to make a boat is to gather dried reeds into bundles and then tie them together. Almost instantly and without extensive effort, you have a floating reed boat. Over the space of a day, the tied and twisted bundles would produce a large boat that can travel many thousands of miles and allow you to fish in safety in the middle of a landscape full of lions, tigers, wolves and bears.
