Consciousness: The Great Leap Forward (Again?)

'Bigger Than The World'

Collective Consciousness

There has been more discussions recently about collective consciousness just recently as we remembered global events that increased our awareness of our world, including 9/11. Actually part of the reason why I blog is because of 9/11. During the aftermath of the terror, heartbreak, and trauma that occurred in NYC, Pennsylvania and the Pentagon on that unforgettable day, there was a palpable change in country I felt. I don't know if it was collective but we all changed. I don't know if we were all connected at some point mentally, spiritually or noetically but somehow our consciousness appeared altered and irrevocably affected. For many months following the siege, the offices of the Wall Street Journal were displaced and journalists were spread out in outposts dispatching daily stories of immense hope, heroicism and triumphs of human spirit. It was difficult not to cry nearly everyday reading what ordinary people were doing endearing unimaginable pain and surviving extraordinary circumstances. Their unique, individual voices could not be missed or forgotten.



Conciousness Emerged 40,000 Years Ago

Intelligence, consciousness, and sentience. AWARENESS... Mmmh... the Matrix (nsfw) expanded my mind and awareness.

Scifi author Robert J. Sawyer wrote an essay in the anthology 'Taking the Red Pill: Science, Philosophy and Religion in The Matrix' entitled 'Artificial Intelligence, Science Fiction, and THE MATRIX'. Regarding humans, 'Intelligence is an emergent property of complex systems. We know that because that's exactly how it happened in us.'

'Anatomically modern humans -- Homo sapien sapiens -- emerged a hundred thousand years ago. Judging by their skulls, these guys had brains identical in size and shape to our own. And yet, for 60,000 years, those brains went along doing only the things nature needed them to do: enabling these early humans to survive.'

'And then, suddenly, 40,000 years ago, it happened: intelligence -- and consciouness itself -- emerged. Anthropologists call it "the Great Leap Forward."'

'Modern-looking human beings had been around for six hundred centuries by that point, but they had created no art, they didn't adorn their bodies with jewelry, and they didn't bury their dead with grave goods. But starting simultaneously 40,000 years ago, suddenly humans were painting beautiful pictures on cave walls, humans were wearing necklaces and bracelets, and humans were interring their loved ones with food and tools and other valuable objects that could only have been of use in a presumed afterlife.'

'Art, fashion, and religion all appeared simultaneously; truly, a great leap forward. intelligence, consciouness, sentience: it came into being, of its own accord, running on hardward that had evolved for other purposes. If it happened once, it might well happen again.'


Will A Different Conciousness Emerge Again?

Could we have another renaissance of culture, arts and technology? A neolithic intelligence, consciousness and sentience...?? I think we are on that path. The mind is the new frontier. Its barriers and miracles of its strength and potential power are being unlocked as we discover more (or learn from our ancestral warriors and healers)... Return to Matrix... energy begets energy. No energy is wasted. Life is sustained (Neo, kiss; Trinity, energetic voltage to the heart like an automated external defibrillator (AED).

Neanderthal Extinction

Neanderthals were far more advanced, culturally and technologically, and appreciative of consciouness more than earlier realized. An updated from Science Daily from today: Neanderthals More Advanced Than Previously Thought: They Innovated, Adapted Like Modern Humans, Research Shows. In terms of adaptation and evolution, the authors note 'Thousands of years ago, southern Italy experienced a shift in climate, becoming increasingly open and arid, said Riel-Salvatore. Neanderthals living there faced a stark choice of adapting or dying out. The evidence suggests they began using darts or arrows to hunt smaller game to supplement the increasingly scarce larger mammals they traditionally hunted. The fact that Neanderthals could adapt to new conditions and innovate shows they are culturally similar to us," he said.

The same speculation is discussed regarding recent information that grasslands were massively decreased as temperatures cooled at the end of the last Ice Age, approximately coinciding with the last days of the Neanderthals. Read Science Daily (August 18, 2010): Dwindling Green Pastures, Not Hunting, May Have Killed Off the Mammoth. As drier tundras replaced productive grasslands, large herbivorous mega-mammals like wooly mammoths, wooly rhinos and giant deer decreased in number. 'These habitat changes made grazing much more difficult for large mammals and dramatically reduced the amount of food available for them. The changes in grassland quality and availability coincided with increases in the distribution and abundance of modern man, Homo sapiens, ensuring a time of wide-scale upheaval for herbivorous mammals and other mammals that preyed on them.'

Where did this leave the Neanderthals, the terrestrial carnivores (see post: Meat Made Us Smart, But Marine-based BAD*SSED)? Well. With considerably lower intakes of brain-nurturing omega-3 sources. Hunting smaller animals and increasing broad spectrum utilization of plant sources as the larger mammals migrated north away from Italian/Mediterranean and Euroasian shoresides toward Slavic and Siberian geographies.

Ancient man on the other hand continued to and perhaps were propelled toward marine-sourced carnivory and less plant based outsourcing as the mega-fauna dwindled in number and size. As brains improved synaptically, the bigger the brain, the bigger the hunt and the bigger the fish/seafood? It appears so from the evidence thus far.



Electrically, electrochemically, what is omega-3?

It fills in and controls our lipid double-layer cell membranes, and membranes are the master controllers in many emerging ways.

It behaves like high-speed internet. Long-chain Omega-3 fatty acids are the strongest, longest 'cables' in nature and behave like the cables of Comcast and DSL for our brain/heart/GI hardware and connections.




Bigger Omega-3 --> Bigger Brain --> Bigger Consciousness --> Bigger Display/Capture --> Bigger S*XXX --> Bigger Progeny/DNA-push-forward

Meat Made Us Smart But... Marine-based, BAD*SSED

Meat Made Us Smart?

Making the evo/paleo blogs are the latest headlines... meat made us smart. NPR's article which is excellent: HERE. Love love LOVE NPR's new series. However. Meat. So what? I'm a carnivore and LUST4MEAT but my higher IQ is not attributed to meat. Figure from Richards et al PNAS 2000 and thank you to Stephan for the forward and rich insights HERE and HERE. Update: Richards et al later re-dated the Neanderthal bones to ~33-40 kya, not the stated ~28,500 yrs ago in the original article (Vindija 207 208 data).




Q: What Made Ancient Humans Rapidly DOMINATE the GLOBE?

A: Marine seafood (fauna and flora) including stems, leaves, tubers, berries, mollusks, crustaceans, fish, seals, dolphins, eels... and etc.




*** Summer Reading ***

Been doing some lightweight, softcore summer reading...
(a) MATT RIDLEY, 'Sex and the evolution of human nature: The Red Queen'
(b) 'Sex at dawn', authored by a psychologist and psychiatrist, C. Ryan and C. Jatha
(c) 'Carbs Can Kill!' by a pharmacist/physician, Dr. Robert Su MD, his personal account of complete health reversal (angina/CAD, skin issues, abdominal obesity, sleep apnea) from an MD point of view on a high saturated fat, carbohydrate-restricted (grain-free) diet. He is a fan of Feinman, Volek and the entire body of low-carb, high fat evidence, which he reviews in articulate and simple terms in his wonderful book. He interviews Sally Fallon author Nourishing Traditions (one of my favorite cookbooks) and WAPFer, HERE. Over 1100+ high sat fat, carb restricted cancer, disease and health references are listed conveniently on his site: HERE.

All 3 were extremely entertaining, enlightening and entirely edifying. Without really arguing the diet point, each of these scientific or sexual-psychosocial or medical/nutritional nonfiction are all for highly descriptive of a behavior or lifestyle written by evolution. (Thanks Dr. Dan for that motto!~) Unfortunately books #1 and #2 don't appear to understand the wild-human diet part... HHHhmmm.

Regarding Sex at dawn, like Melissa who reviewed it earlier HERE at hunt gather love, I agree the authors miss out on romantic love. Where is the LOVE??? Granted... lust does revolve the world around, but again, where's the *heart* sounds.

Also I believe in our human evolutionary history based on our close evo ties to ALL animals, including birds and fish... Ridley argues a better animalistic point that humans are somewhere in behavior (and the genetic studies appear to verify) between the birds and the bonobos/primates... Sexual dimorphism, behavior (mono- v. polygamous depending on fecundity of resources), courtship, songs, pair bonds + affairs, egalitarianism, child/egg rearing, paternity protection, etc. Elaborate shelter construction, prenatal and gestational nesting, omnivorous diet, etc-- Ridley forgot these factors, but I believe these are also common traits.


Biggest Organ

Surprisingly our largest organ which has made the most progressive advances over the last 25 million years... is the BRAIN. Cranial volume has tripled since primates branched off. Neanderthal brains were ~20% larger than current humans. Ancient human brains were also larger but by a smaller fraction, an estimated ~11% larger than currently. An MSNBC 2006 article discusses the microcephalin gene (D variant) which regulates brain size being found in both modern humans and Neanderthals, HERE. Does size matter? I believe so. Above diagram from Trinkaus Richards PNAS 2009, comparing isotope data between Neanderthals, ancient humans and related faunal assemblages.

Author Matt Ridley has tied together an eloquently argued subject that links sexual adaptation, success, survival with human intelligence.

[Smart? He is indeed smart. And funny as H*LL.]


Bigger brains lead to more food.

More food ---> More S*X

More S*X ---> More progeny and so on and so on

Food maybe a relative (Red Queen) euphemism...for any sustenance and nourishment (intellectual, emo, spiritual).




Obviously I've oversimplified and omitted the best thoughts.

Actually the beauty and clarity of Ridley's tight, dense, razor sharp scrutiny of all the lines of evidence and parallels drawn from the wealth of examples from the animal kingdom is how he scintillates the essence of human nature. 'Be different.'

Like a peacock's display, the brain's neurologic display (intelligence, humor, creativity, personality) is the point of attraction that he proposes was selected for over time. It's an interesting contention and makes insanely logical sense.

==>Recap: big brains-->big display-->big S*X-->big progeny





Ancient Humans: More Seafood (More S*X?)

Ridley discusses how bottle-nosed dolphins are perhaps the only other animal (mammal) with intelligence that rivals human intelligence and our complex language skills. However, dolphins brain:body ratios are only ~0.9% whereas humans are vastly higher ~2%. What do ancient humans have in common with our marine cousins, the social pack animal and s*xy/lusty predators, the dolphins?

Neanderthals were incredibly robust, hormonally superb specimens with excellent, dense, powerful bones, and complex communication for large mammal hunts and emerging culture 50-30,000 years ago. Shipman from PennState wrote in PNAS 2008 'Importantly, marine mammals, fish, and mollusks were systematically exploited by both Neanderthals and modern humans throughout the stratigraphic sequences at these caves.'

Above diagram, again, from Trinkaus Richards PNAS 2009. Obviously clear ancient humans were Marine Carnivores and Neanderthals were Herbivore Carnivores (?with possible broad spectrum sourcing including legumes and grasses).

Marine-sourced food is the most highest concentrated sources of omega-3 (marine veggies ALA, marine protein EPA DHA). Most fish or marine mammals don't produce it; THEY EAT IT. From sources concentrated up the food chain starting with algae and phytoplankton up the network, nitrogen and carbon atoms gradually change and can be measured a millenia later.


Omega-3 is BRAIN food.




We are what we eat: Stable 15N 13C Isotope Profiling

Right diagram, courtesy Prof White at Cornell for Geobiochemistry and stable isotopes in paleontology. Nitrogen concentrations up the food chain and marine food networks are laced with more complex hierarchy compared with terrestrial. Carbon is also concentrated up the food chain with again marine sources richer and with higher density carbon atoms compared with land-origin sources. Plants diversified and evolved during the early Miocene 25 mya from Calvin cycle only plants (C3) to more advanced plants that adapted to less water losses (via heat and/or via aridity) with an extra carbon altering step to malate (in the mesophyll vein) before entering the Calvin cycle (C4 plants). During cooling temps or droughts or fires that displaced lush forests and woodlands, grasslands, legumes and grains filled in then eventually flourished (C3 and C4 plants). See Left diagram.

As we can see from Prof White's diagram (right) that Neolithic Europeans who consumed less meat and seafood and more vegetables (C3, C4) had lower density 15N and 13C, compared with marine carnivores: (a) historic Eskimo hunter-gather-fishermen and (b) mesolithic Denmark people.

Go back and examine the 13C data (under 'Big Organ' or HERE) from Richards and Trinkaus PNAS 2009. C13 density is lower for Neanderthals compared with ancient humans yet about the same levels as other carnivores and omnivores (wolf, fox, respectively) and terrestrial small-large herbivores they were known to hunt and consume.

Data exists as early as 50,000 years ago, Neanderthals foraged small grain grasses, legumes and cereals in a small but non-neglible manner. See prior post.

Personally I think it is quite plausible that Neanderthals sourced their food in a very wide way that excluded much marine-based resouces, as indicated by the lack of density in the 15N and 13C isotope evidence.

Why?

I dunno.

Perhaps Neanderthals with their larger brains and early utilization of marine-based foods had a staggering boost in intelligence which translated to a more immense broad-spectrum resource utilization of legumes, small grains and cereals before ancient man got a clue (circa 12,000 years ago, neolithism).

Perhaps Neanderthals failed to figure out how to ferment and displace toxic legume and cereal-containing phytic acid? Ambient warm temperatures are required for fermentation. Perhaps this did not occur sufficiently (and/or by serendipity) until the last glacial maximum ended ~ 16 to 12,000 yrs ago as temperatures rose again finally.

Can a race over-innovate?

Can a race over-innovate to extinction? Esp when the other race is eating omega-3 fish oils by the ton having more s*x and more progeny?
