Brain Evolution Quotes & Sayings

He always reminded us that every atom in our bodies was once part of a distant star that had exploded. He talked about how evolution moves from simplicity toward complexity, and how human intelligence is the highest known expression of evolution. I remember him telling me that a frog's brain is much more complex than a star. He saw human consciousness as the first neuron of the universe coming to life and awareness. A spark in the darkness, waiting to spread to fire. — Greg Iles

The very large brain that humans have, plus the things that go along with it - language, art, science - seemed to have evolved only once. The eye, by contrast, independently evolved 40 times. So, if you were to 'replay' evolution, the eye would almost certainly appear again, whereas the big brain probably wouldn't. — Richard Dawkins

How does the biological wetware of the brain give rise to our experience: the sight of emerald green, the taste of cinnamon, the smell of wet soil? What if I told you that the world around you, with its rich colors, textures, sounds, and scents is an illusion, a show put on for you by your brain? If you could perceive reality as it really is, you would be shocked by its colorless, odorless, tasteless silence. Outside your brain, there is just energy and matter. Over millions of years of evolution the human brain has become adept at turning this energy and matter into a rich sensory experience of being in the world. — David Eagleman

with rare exceptions (chiefly the social insects), mammals and birds are the only organisms to devote substantial attention to the care of their young; an evolutionary development that, through the long period of plasticity which it permits, takes advantage of the large information-processing capability of the mammalian and primate brains. Love seems to be an invention of the mammals. — Carl Sagan

My main reason for scepticism about the Huxley/Sagan theory is that the human brain is demonstrably eager to see faces in random patterns, as we know from scientific evidence, on top of the numerous legends about faces of Jesus, or the Virgin Mary, or Mother Teresa, being seen on slices of toast, or pizzas, or patches of damp on a wall. This eagerness is enhanced if the pattern departs from randomness in the specific direction of being symmetrical. — Richard Dawkins

When you deal with something like compassion for physical pain, which we know is very, very old in evolution - we can find evidence for it in nonhuman species - the brain processes it at a faster speed. Compassion for mental pain took many seconds longer. — Antonio Damasio

Our present intricate humanly consciousness evolved after a long journey of struggle. And the beauty of natural selection is that our struggle against nature made us worthy of being rewarded with the 3 lbs. lump of highly advanced biological computer by our Mother Nature herself. — Abhijit Naskar

If you look at the evolution of the brain, the logic centers, they were growing at the same time as the creative centers were expanding. And that creates this really potent illusion that you're not just a bag of chemicals reacting to shit. Which is what you are. — Tim Cannon

The genes hold culture on a leash. The leash is very long, but inevitably values will be constrained in accordance with their effects on the human gene pool. The brain is a product of evolution. Human behavior-like the deepest capacities for emotional respone which drive and guide it-is the circuitous technique by which human genetic material has been and will be kept intact. — E. O. Wilson

These are the oldest memories on earth, the time codes carried in every chromosome and gene. Every step we've taken in our evolution is a milestone inscribed with organic memories. From the enzymes controlling the carbon-dioxide cycle, to the organization of the brachial plexus and the nerve pathways of the pyramid cells of the mid-brain. Each is a record of a thousand decisions taken in a chemical crisis. Just as psychoanalysis reconstructs the original traumatic situation in order to release the repressed material, so we are now being plunged back into the archaeopsychic past, uncovering the ancient taboos and drives that have been dormant for epochs. — J.G. Ballard

In spite of all these disquieting triumphs in the field of natural science, it's astonishing how little man has learned about himself, and how much there is to learn. How little we know about this brain which made social evolution possible, and of the mind. How little we know of the nature and spirit of man and God. We stand now before this inner frontier of ignorance. If we could pass it, we might well discover the meaning of life and understand man's destiny. — Wilder Penfield

Consider a cow. A cow doesn't have the problem-solving skill of a chimpanzee, which has discovered how to get termites out of the ground by putting a stick into a hole. Evolution has developed the brain's ability to solve puzzles, and at the same time has produced in our brain a pleasure of solving problems. — Martin Gardner

Put simply, behavioural economics argues that human beings' decision-taking is guided by the evolutionary baggage which we bring with us to the present day. Evolution has made us rational to a point, but not perfectly so. It has given us emotions, for example, which programme us to override our rational brain and act more instinctively. — Evan Davis

Thinking is a physical process, the human brain is not exempt from evolution — Steven Pinker

The evolution of the human brain is inextricably interwoven with the expansion of culture and the emergence of language. Thus, it is no coincidence that human beings are story tellers. Through countless generations, humans have gathered to listen to stories of the hunt, the exploits of their ancestors, and morality tales of good and evil...Thus, I believe that both the urge to tell a tale and our vulnerability to being captivate by one are deeply woven into the structures of our brains — Louis Cozolino

[D]umb evolutionary processes have dramatically amplified the intelligence in the human lineage even compared with our close relatives the great apes and our own humanoid ancestors; and there is no reason to suppose Homo sapiens to have reached the apex of cognitive effectiveness attainable in a biological system. — Nick Bostrom

Most of our brain cells are glial cells, once thought to be mere support cells, but now understood as having a critical role in brain function. Glial cells in the human brain are markedly different from glial cells in other brains, suggesting that they may be important in the evolution of brain function. — Thomas R. Insel

Don't you feel something magical when you're in love? ... I do, I certainly do ... but I think that feeling of magic is a hardwired psychological response. It's a chemical thing in the brain. It's a flow of chemicals and electrical currents, and it developed over millions of years in the process of evolution to aid in the procreation of the species. — Alan Lightman

Evolutionary psychologists suggest that, just as the eye is an evolved organ for seeing, and the wing an evolved organ for flying, so the brain is a collection of organs (or 'modules') for dealing with a set of specialist data-processing needs. — Richard Dawkins

People believe in God because the world is very complicated and they think it is very unlikely that anything as complicated as a flying squirrel or the human eye or a brain could happen by chance. — Mark Haddon

An example of perfection in nature is the cockroach. It was living six million years before us and it may outlast us by that long. The brain of a cockroach is a splendid little engine. It doesn't evolve and it doesn't need to. The human brain is a disaster from the point of view of perfection
great intellectual power combined with primitive emotional reactions. Human beings today are living with terrible risks of their own creation
nuclear weapons, the exploitation of natural resources, the great disparity between the wealthy and the poor. Our brains will probably bring us to destruction, but we also have the possibility of growth, evolution. I prefer being a human. We shouldn't always look for perfection, in nature or our lives. — Rita Levi-Montalcini

In the United States, where it has become almost impossible to use "liberal" in the sense in which I have used it, the term "libertarian" has been used instead. It may be the answer; but for my part I find it singularly unattractive. For my taste it carries too much the flavor of a manufactured term and of a substitute. What I should want is a word which describes the party of life, the party that favors free growth and spontaneous evolution. But I have racked my brain unsuccessfully to find a descriptive term which commends itself. — Friedrich August Von Hayek

Plasticity is an intrinsic property of the human brain and represents evolution's invention to enable the nervous system to escape the restrictions of its own genome and thus adapt to environmental pressures, physiologic changes, and experiences. — Philippa Perry

In its evolution from a more primitive nervous system, the brain, as an organ with ten or more billion neurons and many more connections between them must have changed and grown as a result of many accidents. — Stanislaw Ulam

Natural selection has served as a kind of intellectual sieve, producing brains and intelligences increasingly competent to deal with the laws of nature. — Carl Sagan

Finally, our new brain needs a purpose. A purpose is expressed as a series of goals. In the case of our biological brains, our goals are established by the pleasure and fear centers that we have inherited from the old brain. These primitive drives were initially set by biological evolution to foster the survival of species, but the neocortex has enabled us to sublimate them. Watson's goal was to respond to Jeopardy! queries. Another simply stated goal could be to pass the Turing test. To do so, a digital brain would need a human narrative of its own fictional story so that it can pretend to be a biological human. It would also have to dumb itself down considerably, for any system that displayed the knowledge of, say, Watson would be quickly unmasked as nonbiological. — Ray Kurzweil

The evolution of the brain not only overshot the needs of prehistoric man, it is the only example of evolution providing a species with an organ which it does not know how to use. — Arthur Koestler

However, we have the benefits of the billions of years of evolution that have already taken place, which are responsible for the greatly increased order of complexity in the natural world. We can now benefit from it by using our evolved tools to reverse engineer the products of biological evolution (most importantly, the human brain). — Ray Kurzweil

I mean to say, I know perfectly well that I've got, roughly speaking, half the amount of brain a normal bloke ought to possess. And when a girl comes along who has about twice the regular allowance, she too often makes a bee line for me with the love light in her eyes. I don't know how to account for it, but it is so."
"It may be Nature's provision for maintaining the balance of the species, sir. — P.G. Wodehouse

I believe that humans are on an evolutionary path where brain usage will escalate beyond the current 10% standard, and as we evolve, so will our "ESP" abilities. Today, more and more children are born already possessing these abilities, and it's appropriate we adjust to the new world reality already happening. — Tessie Jayme

If organs as elemental as brain and heart can be persuaded to regenerate, and others, like ears and corneas, can be fashioned from living ink, how will that change us as a species? Will the printing of organs affect our evolution? Could it alter our genes? — Diane Ackerman

We should not be too quick to dismiss our own [ocular] arrangement. As so often in biology, the situation is more complex ... we have the advantage that our own light-sensitive cells are embedded directly in their support cells (the retinal pigment epithelium) with an excellent blood supply immediately underneath. Such an arrangement supports the continuous turnover of photosensitive pigments. The human retina consumes even more oxygen than the brain, per gram, making it the most energetic organ in the body. — Nick Lane

Imagine a forty-five-year-old male fifty feet long, a slim, shiny black animal cutting the surface of green ocean water at twenty knots. At fifty tons it is the largest carnivore on earth. Imagine a four-hundred-pound heart the size of a chest of drawers driving five gallons of blood at a stroke through its aorta; a meal of forty salmon moving slowly down twelve-hundred feet of intestine ... the sperm whale's brain is larger than the brain of any other creature that ever lived ... With skin as sensitive as the inside of your wrist. — Barry Lopez

Scholars once proclaimed that the agricultural revolution was a great leap forward for humanity. They told a tale of progress fuelled by human brain power. Evolution gradually produced ever more intelligent people. Eventually, people were so smart that they were able to decipher nature's secrets, enabling them to tame sheep and cultivate wheat. As soon as this happened, they cheerfully abandoned the gruelling, dangerous, and often spartan life of hunter-gatherers, settling down to enjoy the pleasant, satiated life of farmers. — Yuval Noah Harari

There is a common misconception that the human brain is the pinnacle of billions of years of evolution. This may be true if we think of the entire nervous system. However, the human neocortex itself is a relatively new structure and hasn't been around long enough to undergo much long-term evolutionary refinement. — Jeff Hawkins

Man is not going to wait passively for millions of years before evolution offers him a better brain. — Corneliu E Giurgea

Throughout the evolution of mankind our very much primordial ancestors had one thing in common, it was ignorance. This ignorance gave birth to fear. Fear of the unknown became a quintessential element of their daily survival. To ace the intensity of the fear, rituals of worship arose. — Abhijit Naskar

The human mind has a desire to know its place in the universe and the role we play in the tapestry of life. This is actually hardwired into our brains, the desire the know our relationship to the universe. This was good for our evolution, since it enabled us to see our relationship to others and to nature which was good for our survival. And it is also what drives our curiosity to understand the universe. — Michio Kaku

The self-same atoms which, chaotically dispersed, made the nebula, now, jammed and temporarily caught in peculiar positions, form our brains; and the 'evolution' of brains, if understood, would be simply the account of how the atoms came to be so caught and jammed. — William James

The evolution of the brain is directly proportionate to the evolution of humanity. Only when the brain has collected enough data about war, will it move on to collate information about love. — Craig Stone

Man is still at the learning stage, and mankind is so arrogant to think that he's the highest form of evolution on earth. There's so much of the brain that we still don't use, and that's all I ever try to do - go to the next level — Marilyn Manson

The brain rewards us for interacting with beautiful things. In this way, evolution wants to encourage us to do what is good for us. — Frank Wilczek

It's the old idea that the process of evolution is some push in the direction of greater complexity
in particular greater intellectual complexity. In one twig of the tree of life, namely ours, having a big brain happened to have advantages. But that's just what worked for a particular species of primate 5 to 7 million years ago. — Steven Pinker

Life is unlikely to end with humans, even if we burn in a nuclear holocaust. The relentless wheel of evolution will pick up from where we leave off and roll to it's predestined goal. If the human mind continues to evolve, enlarge, and expand, so that we are able to recognize our kinship with the creations around us, so that we are able to grasp our oneness with the cosmos, and so that we merge in yoga with the Divine, the long cosmic cycle will disclose its cryptic secret, and the long saga of billions of years of evolution will display its profound significance. — Roy J. Mathew

In creating the human brain, evolution has wildly overshot the mark. — Arthur Koestler

I meditate because evolution gave me a big brain, but it didn't come with an instruction manual. I meditate because life is too short and sitting slows it down. I meditate because life is too long and I need an occasional breakI meditate because it's such a relief to spend time ignoring myselfI meditate because I'm building myself a bigger and better perspective, and occasionally I need to add a new window. — Wes Nisker

[W]e may now be on the threshold of a new kind of genetic takeover. DNA replicators built 'survival machines' for themselves - the bodies of living organisms including ourselves. As part of their equipment, bodies evolved onboard computers - brains. Brains evolved the capacity to communicate with other brains by means of language and cultural traditions. But the new milieu of cultural tradition opens up new possibilities for self-replicating entities. The new replicators are not DNA and they are not clay crystals. They are patterns of information that can thrive only in brains or the artificially manufactured products of brains - books, computers, and so on. But, given that brains, books and computers exist, these new replicators, which I called memes to distinguish them from genes, can propagate themselves from brain to brain, from brain to book, from book to brain, from brain to computer, from computer to computer. — Richard Dawkins

It is important to understand that while oxytocin may be the hub of the evolution of the social brain in mammals, it is part of a very complex system. Part of what it does is act in opposition to stress hormones, and in that sense release of oxytocin feels good - as stress hormones and anxiety do not feel good. — Patricia Churchland

Thinking is computation, I claim, but that does not mean that the computer is a good metaphor for the mind. The mind is a set of modules, but the modules are not encapsulated boxes or circumscribed swatches on the surface of the brain. The organization of our mental modules comes from our genetic program, but that does not mean that there is a gene for every trait or that learning is less important than we used to think. The mind is an adaptation designed by natural selection, but that does not mean that everything we think, feel, and do is biologically adaptive. We evolved from apes, but that does not mean we have the same minds as apes. And the ultimate goal of natural selection is to propagate genes, but that does not mean that the ultimate goal of people is to propagate genes. — Steven Pinker

In brief: consciousness is a phenomenon in the zone of evolution. This world lights up to itself only where or only inasmuch as it develops, procreates new forms. Places of stagnancy slip from consciousness; they may only appear in their interplay with places of evolution.
If this is granted it follows that consciousness and discord with one's own self are inseparably linked up, even that they must, as it were, be proportional to each other. This sounds a paradox, but the wisest of all times and peoples have testified to confirm it. Men and women for whom this world was lit in an unusually light of awareness, and who by life and word have, more than others, formed and transformed that work of art which we call humanity, testify by speech and writing or even by their lives that more than others have they been torn by the pangs of inner discord. Let this be a consolation to him who also suffers from it. Without it nothing enduring has ever been begotten. — Erwin Schrodinger

Chosen are those artists who penetrate to the region of that secret place where primeval power nurtures all evolution. There, where the powerhouse of all time and space call it brain or heart of creation activates every function, who is the artist who would not dwell there? — Paul Klee

But there's a problem," Dr. Bramble said. He tapped his forehad. "And it's right up here." Our greatest talent, he explained, also created the monster that could destroy us. "Unlike any other organism in history, humans have a mind-body conflict: we have a body built for performance, but a brain that's always looking for efficiency." We live or die by our endurance, but remember: endurance is all about conserving energy, and that's the brain's department. "The reason some people use their genetic gift for running and others don't is because the brain is a bargain shopper. — Christopher McDougall

For three million years we were hunter-gatherers, and it was through the evolutionary pressures of that way of life that a brain so adaptable and so creative eventually emerged. Today we stand with the brains of hunter-gatherers in our heads, looking out on a modern world made comfortable for some by the fruits of human inventiveness, and made miserable for others by the scandal of deprivation in the midst of plenty. — Richard E. Leakey

So my eyes spotted it and my brain processed it and rejected it instantly, on a purely preprogrammed basis. And then it hung up on it. Out of pure animal instinct. Because it looked like a snake. The lizard part of my brain whispered snake and I got that little primeval jolt of fright that had kept my ancestors alive and well way back in evolution. It was all over in a split second. It was smothered immediately. The modern educated part of my mind stepped in and said, No snakes here in January, bud. Way too cold. I breathed out and moved on a step and then paused to look back, purely out of curiosity. — Lee Child

It is very difficult to evolve by altering the deep fabric of life; any change there is likely to be lethal. But fundamental change can be accomplished by the addition of new systems on top of old ones. — Carl Sagan

The collective unconscious contains the whole spiritual heritage of mankind's evolution born anew in the brain structure of every individual. — Carl Jung

It has taken four billion years of evolution to generate this kind of organism with this kind of brain, and yet we wake up in the morning and feel bored. — Stephen Batchelor

In a way, science might be described as paranoid thinking applied to Nature: we are looking for natural conspiracies, for connections among apparently disparate data. Our objective is to abstract patterns from Nature (right-hemisphere thinking), but many proposed patterns do not in fact correspond to the
data. Thus all proposed patterns must be subjected to the sieve of critical analysis (left-hemisphere thinking). — Carl Sagan

Perhaps the locale of the subjunctive mood will
one day be found. Will Latins turn out to be extravagantly endowed and English-speaking peoples significantly short-changed in this minor piece of brain anatomy? — Carl Sagan

Humans are built to move. We evolved under conditions that required daily intense physical activity, and even among individuals with lower physical potential, that hard-earned genotype is still ours today. The modern sedentary lifestyle leads to the inactivation of the genes related to physical performance, attributes that were once critical for survival and which are still critical for the correct, healthy expression of the genotype. The genes are still there, they just aren't doing anything because the body is not stressed enough to cause a physiological adaptation requiring their activation. The sedentary person's heart, lungs, muscles, bones, nerves and brain all operate far below the level at which they evolved to function, and at which they still function best. — Mark Rippetoe

The concept of God is generated by a brain designed by evolution to find design in nature (a very recursive idea). — Michael Shermer

On the other hand, mere critical thinking, without creative and intuitive insights, without the search for new patterns, is sterile and doomed. To solve complex problems in changing circumstances requires the activity of both cerebral hemispheres: the path to the future lies through the corpus callosum. — Carl Sagan

If (early humans) weren't using and refining language I would like to know what they were doing with their autocatalytically increasing brains. — Dean Falk

The complex organic device that creates and thereafter drives consciousness, is the human brain. Consciousness evolved hand in hand with the evolution of the human brain throughout a time span of six million years. — Abhijit Naskar

In modern neurotheology we examine the physical bases to spiritual, religious and mystical experiences and beliefs, that implicitly appear to reduce this rich phenomenology to only neuronal functions. So, the thing is, there was no divine intervention necessary in the evolution of spirituality and religiosity. "Human Brain is the true God of all beliefs". — Abhijit Naskar

Just about every adult human being back then had a brain weighing about three kilogrammes! There was no end to the evil schemes that a thought machine that oversized couldn't imagine and execute.
So I raise this question, although there is nobody around to answer it: Can it be doubted that three-kilogramme brains were once nearly fatal defects in the evolution of the human race? — Kurt Vonnegut

The talent for self-justification is surely the finest flower of human evolution, the greatest achievement of the human brain. When it comes to justifying actions, every human being acquires the intelligence of an Einstein, the imagination of a Shakespeare, and the subtlety of a Jesuit. — Michael Foley

Those mothers with hereditary large pelvises were able to bear large-brained babies who because of their superior intelligence were able to compete successfully in adulthood with the smaller-brained offspring of mothers with smaller pelvises. — Carl Sagan

Our earliest ancestors were descended from primates who thrived for millions of years in a treetop environment, and who in the process had evolved one of the most remarkable visual systems in nature. To move quickly and efficiently in such a world, they developed extremely sophisticated eye and muscle coordination. Their eyes slowly evolved into a full-frontal position on the face, giving them binocular, stereoscopic vision. This system provides the brain a highly accurate three-dimensional and detailed perspective, but is rather narrow. Animals that possess such vision - as opposed to eyes on the side or half side - are generally efficient predators like owls or cats. They use this powerful sight to home in on prey in the distance. Tree-living primates evolved this vision for a different purpose - to navigate branches, and to spot fruits, berries, and insects with greater effectiveness. They also evolved elaborate color vision. — Robert Greene

Our surmises regarding the subtle functions of neural processes within the brain are profoundly constrained by the fact that the brain did not evolve in order to understand itself. The complex organization of the brain evolved as a consequence of our sensorial and muscled engagement with the landscapes that surround us. — David Abram

MacLean has shown that the R-complex plays an important role in aggressive behavior, territoriality, ritual and the establishment of social hierarchies. Despite occasional welcome exceptions, this seems to me to characterize a great deal of modern human bureaucratic and political behavior. — Carl Sagan

There probably is no more important quest in all science than the attempt to understand those very particular events in evolution by which brains worked out that special trick that has enabled them to add to the cosmic scheme of things: color, sound, pain, pleasure, and all the other facets of mental experience. — Roger Wolcott Sperry

Much more plausible is the computer-based explanation that dreams are a spillover from the unconscious processing of the day's experience, from the brain's decision on how much of the daily events temporarily stored in a kind of buffer to emplace in long-term memory... The American psychiatrist Ernest Hartmann of Tufts University has provided
anecdotal but reasonably persuasive evidence that people who are engaged in intellectual activities during the day, especially unfamiliar intellectual activities, require more sleep at night, while, by and large, those engaged in mainly repetitive and intellectually unchallenging tasks are able to do with much less sleep. — Carl Sagan

The human brain is still undergoing rapid adaptive evolution,. — Howard Hughes

Night was falling. Birds were singing. Birds were, it occurred to me to say, enacting a frantic celebration of day's end. They were manifesting as the earth's bright-colored nerve endings, the sun's descent urging them into activity, filling them individually with life nectar, the life nectar then being passed into the world, out of each beak, in the form of that bird's distinctive song, which was, in turn, an accident of beak shape, throat shape, breast configuration, brain chemistry: some birds blessed in voice, others cursed; some squeaking, others rapturous. — George Saunders

If evolution is true, you could not know that it's true because your brain is nothing but chemicals. Think about that. — Kent Hovind

It is interesting that it is not the getting of any sort of knowledge that God has forbidden, but, specifically, the knowledge of the difference between good and evil-that is, abstract and moral judgments, which, if they reside anywhere, reside in the neocortex. — Carl Sagan

A somewhat casual observer from outer space might well deduce that the course of evolution in this planet had produced a species of large four-wheeled bugs with detachable brains; peculiar animals which rested when they sent their brains away from them but performed in rather predictable manner when their brains were recalled. — Kenneth E. Boulding

As the neo-cortex of the brain keeps getting more complex through further evolution, eventually our far away progeny will born in a world where there will be no more religion to be endowed upon them. — Abhijit Naskar

It is not a pumping-in from the outside that gives wisdom; it is the power and extent of your inner receptivity that determines how much you can attain of true knowledge, and how rapidly. You can quicken your evolution by awakening and increasing the receptive power of your brain cells. — Paramahansa Yogananda

I've always been fascinated with adrenaline; it's saved my life more than once, and it's caused me to need it to save my life more than once. One of the most fascinating responses in human evolution, adrenaline sharpens your brain; it sharpens your responses. — Craig Venter

There is no doubt that right-hemisphere intuitive thinking may perceive patterns and connections too difficult for the left hemisphere; but it may also detect patterns where none exist. Skeptical and
critical thinking is not a hallmark of the right hemisphere. And unalloyed right-hemisphere doctrines, particularly when they are invented during new and trying circumstances, may be erroneous or paranoid. — Carl Sagan

Out of the choked Devonian waters emerged sight and sound and the music that rolls invisible through the composer's brain. They are there still in the ooze along the tideline, though no one notices. The world is fixed, we say: fish in the sea, birds in the air. But in the mangrove swamps by the Niger, fish climb trees and ogle uneasy naturalists who try unsuccessfully to chase them back to the water. There are things still coming ashore. — Loren Eiseley

We live in the Age of the Higher Brain, the cerebral cortex that has grown enormously over the last few millennia, overshadowing the ancient, instinctive lower brain. The cortex is often called the new brain, yet the old brain held sway in humans for millions of years, as it does today in most living things. The old brain can't conjure up ideas or read. But it does possess the power to feel and, above all, to be. It was the old brain that caused our forebears to sense the closeness of a mysterious presence everywhere in Nature. — Deepak Chopra

So far as I know, childbirth is generally painful in only one of the millions of species on Earth: human beings. This must be a consequence of the recent and continuing increase in cranial volume... Childbirth is painful because the evolution of the human skull has been spectacularly fast and recent. — Carl Sagan

Our great human adventure is the evolution of consciousness. We are in this life to enlarge the soul, liberate the spirit, and light up the brain. — Tom Robbins

Some evidence suggests the left-handers are more likely to have problems with such left-hemisphere functions as reading, writing, speaking and arithmetic; and to be more adept at such right -hemisphere functions as imagination, pattern recognition and general creativity. — Carl Sagan

Our primate ancestors was the development of a larger cerebral cortex as well as the development of increased volume of gray-matter tissue in certain regions of the brain.32 This change occurred, however, on the very slow timescale of biological evolution and still involves an inherent — Ray Kurzweil

All that's known is this: there is no central processor, no single computer. Nothing that simple. Millions of neurons process information simultaneously and in parallel, not linearly, but the actual chemistry and electrical properties of that integrative process are still being mapped. Even so, it seems odd that during the evolution of brain circuitry and thinking, the ability to understand itself did not get wired in. Such built-in innocence seems like a terrible oversight. — Gretel Ehrlich

I was taught that the human brain was the crowning glory of evolution so far, but I think it's a very poor scheme for survival. — Kurt Vonnegut

Inside our skulls are fish, reptile and shrew brains, as well as the highest centers that allow us to integrate information in our unique way; and some of our newer brain components talk to each other via some very ancient structures indeed. Our brains are makeshift structures, opportunistically assembled by Nature over hundreds of millions of years, and in multiple different ecological contexts. — Ian Tattersall

Such a social-media environment; it is merely the most recent and most efficient way that humans have found to scratch a prehistoric itch. The compelling nature of social media, then, can be traced back in part to the evolution of the social brain, as — Tom Standage

Many humans make the mistake of fighting for race when it's the species driving our genes. And there is only one weapon to fight for species: the brain. — Anthony Marais

Evolution sceptic: Professor Haldane, even given the billions of years that you say were available for evolution, I simply cannot believe it is possible to go from a single cell to a complicated human body, with its trillions of cells organized into bones and muscles and nerves, a heart that pumps without ceasing for decades, miles and miles of blood vessels and kidney tubules, and a brain capable of thinking and talking and feeling. JBS: But madam, you did it yourself. And it only took you nine months. — Richard Dawkins

There was something built into the human brain by natural selection which was once useful, and which now manifests itself as religion. — Richard Dawkins

Don't we introduce time as a means of becoming more evolved? The brain has evolved but is there evolution inwardly? Can the brain dominated by time not be subservient to it? — Jiddu Krishnamurti

The brain is the great factory of thought. To it are directed all the forces of nature, forces which, for thousands of years, have been expending themselves upon it and impressing on it a slow and continuous motion of evolution. — Leonardo Bianchi
