Animal Evolution Quotes & Sayings

An evolutionary perspective of our place in the history of the earth reminds us that Homo sapiens sapiens has occupied the planet for the tiniest fraction of that planet's four and a half thousand million years of existence. In many ways we are a biological accident, the product of countless propitious circumstances. As we peer back through the fossil record, through layer upon layer of long-extinct species, many of which thrived far longer than the human species is ever likely to do, we are reminded of our mortality as a species. There is no law that declares the human animal to be different, as seen in this broad biological perspective, from any other animal. There is no law that declares the human species to be immortal. — Richard E. Leakey

Existence loves laughter. You may have observed, or not, that man is the only animal in the whole of existence who is capable of laughing. Laughter is the only distinguishing mark that you are not a buffalo, you are not a donkey; you are a human being. Laughter defines your humanity and your evolution. And the greatest laugh is at your own ridiculous things. — Rajneesh

We cannot separate ourselves from those whom we call the 'lower' animals. They are lower in the scale of evolution, but they, like us, are members of the One Family. We must not take away the life of any creature. Indeed, we must never take away that which we cannot give. And as we cannot restore a dead creature to life, we have no right to take away its' life. — Dada Vaswani

Our animal origins are constantly lurking behind, even if they are filtered through complicated social evolution. — Richard Dawkins

When I was an animal I evolved through selfishness. Now that I am a man my evolution can be achieved only through self-sacrifice. — Sri Chinmoy

Moreover, like eyes and arms, the fundamental structures of the mind (and the informational capacities they support) aren't acquired through experience: the pioneering ethologists realized that behavior in general must be understood in the light of evolution, and this same conviction is held by the new wave of cognitive ethologists. Whatever else may be said, we expect to find that many (if not all) of the critical properties of animal minds are - like motor patterns - intrinsic traits of an organism that are adaptive consequences of evolution. — Raymond Coppinger

at least some paleontologists believe that the demise
of the dinosaurs was accelerated by nocturnal predation on reptilian eggs by the early mammals. Two chicken eggs for breakfast may be all-at least on the surface-that is left of this ancient mammalian cuisine. — Carl Sagan

Having escaped the Dark Ages in which animals were mere stimulus-response machines, we are free to contemplate their mental lives. It is a great leap forward, the one that Griffin fought for. But now that animal cognition is an increasingly popular topic, we are still facing the mindset that animal cognition can be only a poor substitute of what we humans have. It can't be truly deep and amazing. Toward the end of a long career, many a scholar cannot resist shining a light on human talents by listing all the things we are capable of and animals not. From the human perspective, these conjectures may make a satisfactory read, but for anyone interested, as I am, in the full spectrum of cognitions on our planet, they come across as a colossal waste of time. What a bizarre animal we are that the only question we can ask in relation to our place in nature is "Mirror, mirror on the wall, who is the smartest of them all? — Frans De Waal

Rocks are not static and inert. They are constantly changing, shifting, and rearranging their form and location. They can be melted, deposited, eroded and squeezed into new forms... They offer clues about the shifting, changing nature of the continents, mountain ranges, oceans and islands... When an animal or plant dies and its remains leave an impression in rock, the resulting fossil is a testament to life's history and its changing, evolving nature... Explore the fossils life has left as clues to its evolution. — Robert R. Coenraads

You are hierarchical. That's the older and more entrenched characteristic. We saw it in your closest animal relatives and in your most distant ones. It's a terrestrial characteristic. When human intelligence served it instead of guiding it, when human intelligence did not even acknowledge it as a problem, but took pride in it or did not notice it at all ... That was like ignoring cancer. — Octavia E. Butler

judgment is the most important faculty we have. An animal, or a man, may get on very well without 'abstract attitude' but will speedily perish if deprived of judgment. Judgment must be the first faculty of higher life or mind - yet it is ignored, or misinterpreted, by classical (computational) neurology. And if we wonder how such an absurdity can arise, we find it in the assumptions, or the evolution, of neurology itself. — Oliver Sacks

The human animal began as a mere wriggling thing in the ancient seas, struggling out onto land with many regrets. That is what brings us so full of longing to the sea. — Sebastian Barry

At that moment there was no need of any scientific knowledge to understand his communication of reassurance. The soft pressure of his fingers spoke to me not through my intellect but through a more primitive emotional channel: the barrier of untold centuries which has grown up during the separate evolution of man and chimpanzee was, for those few seconds, broken down.

It was a reward far beyond my greatest hopes. — Jane Goodall

Anthropomorphism is such an interesting concept. It means projecting human thoughts and emotions onto an animal. Which implies that thoughts and feelings belong to humans alone. Of course, if you believe in evolution, or if you believe in the Bible, that's not so. Both evolution and the Bible tell us that we're part of a family. — Sy Montgomery

At some point, human intelligence became collective and cumulative in a way that happened to no other animal. — Matt Ridley

[...] if truth be told, evolution hasn't yielded many practical or commercial benefits. Yes, bacteria evolve drug resistance, and yes, we must take countermeasures, but beyond that there is not much to say. Evolution cannot help us predict what new vaccines to manufacture because microbes evolve unpredictably. But hasn't evolution helped guide animal and plant breeding? Not very much. Most improvement in crop plants and animals occurred long before we knew anything about evolution, and came about by people following the genetic principle of 'like begets like'. Even now, as its practitioners admit, the field of quantitative genetics has been of little value in helping improve varieties. Future advances will almost certainly come from transgenics, which is not based on evolution at all.
[review of The Evolving World: Evolution in Everyday Life, Nature 442, 983-984 (31 August 2006)] — Jerry A. Coyne

What an immature, self-destructive, antiquated mischief is man! How obscure and gross his prancing and chattering on his little stage of evolution! How loathsome and beyond words boring all the thoughts and self-approval of his biological by-product! this half-formed, ill-conditioned body! this erratic, maladjusted mechanism of his soul: on one side the harmonious instincts and balanced responses of the animal, on the other the inflexible purpose of the engine, and between them man, equally alien from the being of Nature and the doing of the machine, the vile becoming! — Evelyn Waugh

Why run? I run because I am an animal. I run because it is part of my genetic wiring. I run because millions of years of evolution have left me programmed to run. And finally, I run because there's no better way to see the sun rise and set ... What the years have shown me is that running clarifies the thinking process as well as purifies the body. I think best - most broadly and most fully - when I am running. — Amby Burfoot

[Darwin] gave an answer to the tremendous question that so deeply concerns...What is Man? [He] answered this question to the effect that man is a natural product of the universe;...man is an animal, a vertebrate, a mammal, and a primate....By bringing man into the evolutionary picture, Darwin finally took the last step in our emancipation and finally made our world rational. [Yet] Darwin felt humility and awe that seem to me truly religious. ["Darwin led us into this modern world," 1959, p. 271-272.] — George Gaylord Simpson

Animals are locked in a perpetual present. They can learn from recent events, but they are easily distracted by what is in front of their eyes. Slowly, over a great period of time, our ancestors overcame this basic animal weakness. By looking long enough at any object and refusing to be distracted - even for a few seconds - they could momentarily detach themselves from their immediate surroundings. In this way they could notice patterns, make generalizations, and think ahead. They had the mental distance to think and reflect, even on the smallest scale.
These early humans evolved the ability to detach and think as their primary advantage in the struggle to avoid predators and find food. It connected them to a reality other animals could not access. Thinking on this level was the single greatest turning point in all of evolution - the emergence of the conscious, reasoning mind. — Robert Greene

People are only animals, but special animals. Every animal has fought and killed to survive, even before the dinosaurs. We're the only ones that do it for fun. That's why I don't know about Darwinism. Supposedly evolution and natural selection are all about survival, but we haven't gotten smarter over the years, only more dangerous. — Kurt Vonnegut

The sleeping style of each organism is exquisitely
adapted to the ecology of the animal. It is conceivable that animals who are too stupid to be quiet on their own initiative are, during periods of high risk, immobilized by the implacable arm of sleep. — Carl Sagan

He who believes that each being has been created as we now see it, must occasionally have felt surprise when he has met with an animal having habits and structure not at all in agreement. — Charles Darwin

Human beings are so destructive. I sometimes think we're a kind of plague, that will scrub the earth clean. We destroy things so well that I sometimes think, maybe that's our function. Maybe every few eons, some animal comes along that kills off the rest of the world, clears the decks, and lets evolution proceed to its next phase. — Michael Crichton

Might one not say that in the chance combination of nature's production, since only those endowed with certain relations of suitability could survive, it is no cause for wonder that this suitability is found in all species that exist today? Chance, one might say, produced an innumerable multitude of individuals; a small number turned out to be constructed in such fashion that the parts of the animal could satisfy its needs; in another, infinitely greater number, there was neither suitability nor order: all of the later have perished; animals without a mouth could not live, others lacking organs for reproduction could not perpetuate themselves: the only ones to have remained are those in which were found order and suitability; and these species, which we see today, are only the smallest part of what blind fate produced. — Pierre-Louis Moreau De Maupertuis

And so we see the paradox that evolution has handed us. If man is the only animal whose consciousness of self gives him an unusual dignity in the animal kingdom, he also pays a tragic price for it. The fact that the child has to identify -first- means that his very first identity is a social product. His habitation of his own body is built from the outside in; not from the inside out. He doesn't unfold into the world, the world unfolds into him. As the child responds to the vocal symbols learned from his object, he often gives the pathetic impression of being a true social puppet, jerked by alien symbols and sounds. What sensitive parent does not have his satisfaction tinged with sadness as the child repeats with such vital earnestness the little symbols that are taught him? — Ernest Becker

I realized that nature had invented reproduction as a mechanism for life to move forward, as a life force that passes right through us and makes us a link in the evolution of life. Rarely seen by the naked eye, this intersection between the animal world and the plant world is truly a magic moment. — Louie Schwartzberg

But nature - that is, biological evolution - has not fitted man to any specific environment. On the contrary, ... he has a rather crude survival kit; and yet -this is the paradox of the human condition - one that fits him to all environments. Among the multitude of animals which scamper, fly, burrow and swim around us, man is the only one who is not locked into his environment. His imagination, his reason, his emotional subtlety and toughness, make it possible for him not to accept the environment but to change it. — Jacob Bronowski

Adam and Eve derived the fullness of joy and bliss from their contemplation of all the animal creatures. — Martin Luther

Thus by an unprejudiced observation of the animal kingdom, we reach the conclusion that wherever society exists at all, this principle may be found: Treat others as you would like them to treat you under similar circumstances. And when we study closely the evolution of the animal world, we discover that the aforesaid principle, translated by the one word Solidarity, has played an infinitely larger part in the development of the animal kingdom than all the adaptations that have resulted from a struggle between individuals to acquire personal advantages. — Pyotr Kropotkin

The meaning that we are seeking in evolution is its meaning to us, to man. The ethics of evolution must be human ethics. It is one of the many unique qualities of man, the new sort of animal, that he is the only ethical animal. The ethical need and its fulfillment are also products of evolution, but they have been produced in man alone. — George Gaylord Simpson

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

The significance of language for the evolution of culture lies in this, that mankind set up in language a separate world beside the other world, a place it took to be so firmly set that, standing upon it, it could lift the rest of the world off its hinges and make itself master of it. To the extent that man has for long ages believed in the concepts and names of things as in aeternae veritates he has appropriated to himself that pride by which he raised himself above the animal: he really thought that in language he possessed knowledge of the world. — Friedrich Nietzsche

The distinguishing of the strata, or layers, in the embryonic membrane was a turning-point in the study of the history of evolution, and placed later researches in their proper light. A division of the (disc-shaped) embryo into an animal and a plastic part first takes place. In the lower part (the plastic or vegetative layer) are a serous and a vascular layer, each of peculiar organization. In the upper part also (the animal or serous germ-layer) two layers are clearly distinguishable, a flesh-layer and a skin-layer. (1828) — Karl Ernst Von Baer

It is not true that the unconscious goal in the evolution of every conscious being (animal, man, mankind, etc) is its 'highest happiness': the case, on the contrary, is that every stage of evolution possesses a special and incomparable happiness neither higher nor lower but simply its own. Evolution does not have happiness in view, but evolution and nothing else. — Friedrich Nietzsche

The question of the position of man, as an animal, has given rise to much disputation, with the result of proving that there is no anatomical or developmental character by which he is more widely distinguished from the group of animals most nearly allied to him, than they are from one another. — Thomas Henry Huxley

From the Hive Manual. The relationship between ecology and evolution is extremely close, deeply implicated in organic changes among a given animal population, and profoundly sensitive to the density of numbers within a given habitat. Our adaptations aim to increase the population tolerance, to permit a human density ten to twelve times greater than is currently considered possible. Out of this, we will get our survival variations. — Frank Herbert

Evolution is no longer just a theory; it has been proven true beyond a reasonable doubt. The problem is, even people who believe evolution is true disassociate themselves from the process. They somehow skipped all the lower forms of animal life and just started out at the top of the evolutionary ladder.

The evidence says we evolved as life evolved.

Human beings did not just appear at the top of the evolutionary ladder to reap the benefits of those millions of years of evolution without having to live through it.

In other words, you were those other animals. Someone had to be them.

You had to be lower animals to be a human now. You lived as all the different animals in your evolutionary line. You lived through millions of years, and millions of lives and deaths to get to where you are now. That's what Darwin's book means. — Michael Smith

The evolution of the human race will not be accomplished in the ten thousand years of tame animals, but in the million years of wild animals, because man is, and always will be, a wild animal. — Charles Galton Darwin

in the past fifty years people in many Western societies have come to feel compassion in response to many more kinds of animal suffering, and they've come to feel disgust in response to many fewer kinds of sexual activity. The current triggers can change in a single generation, even though it would take many generations for genetic evolution to alter the design of the module and its original triggers. — Anonymous

I had written the sentence, 'You mustn't think that the evolution that gave rise to us was the only evolutionary possibility on this planet ... that cultural developments could be shaped through the mediation of another animal species. If the biological conditions were favorable, some civilization not inferior to our own could arise in the depths of the sea ... Would it do the same stupid things mankind has done? Would it invite the same historical calamities? What would we say if some animal other than man declared that its education and its numbers gave it the sole right to occupy the entire world and hold sway over all creation? — Karel Capek

Evolution is not finished; reason is not the last word nor the reasoning animal the supreme figure of Nature. As man emerged out of the animal, so out of man the superman emerges. — Sri Aurobindo

It's in the nature of the humans and the entire animal kingdom to return blow for blow, cheating for cheating, lie for lie, to hit back with all our might. But what makes us true humans is the power to not hit back. — Abhijit Naskar

It was our Creator who led us through the stages of evolution, from the animal state to the human. His purpose was to make us intelligent and aware, so that we might know Him. — Rumi

The whole question of evolution seems less momentous than it did, because, unlike the Victorians, we do not feel that to be descended from animals is degrading to human dignity. — George Orwell

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

Genetically we're just the third species of chimp, a physically weak but social animal. It was in our interests to communicate complex ideas so we could cooperate to hunt big, dangerous prey animals. I think as soon as humans developed language with grammar that allowed for abstract thought, we were set on a whole new evolutionary path, made by and for the spread of ideas instead of genes. — K. Valisumbra

In The Moral Animal, Robert Wright laments, "A basic underlying dynamic between men and women is mutual exploitation. They seem, at times, designed to make each other miserable."
Don't believe it. We aren't designed to make each other miserable. This view holds evolution responsible for the mismatch between our evolved predispositions and the post-agricultural socioeconomic world we find ourselves in. The assertion that human beings are naturally monogamous is not just a lie; it's a lie most Western societies insist we keep telling each other. — Cacilda Jetha

Man is a megalomaniac among animals-if he sees mountains he will try to imitate them by pyramids, and if he sees some grand process like evolution, and thinks it would be at all possible for him to be in on that game, he would irreverently have to have his whack at that too. That daring megalomania of his-has it not brought him to his present place? — Jacques Loeb

Why should our nastiness be the baggage of an apish past and our kindness uniquely human? Why should we not seek continuity with other animals for our 'noble' traits as well? — Stephen Jay Gould

This is the "burglar-alarm" theory of bioluminescence: by turning on its lights, an animal may create enough of a scene to draw the attention of its predator's predator, and thereby perhaps save itself. The corollary of the burglar-alarm theory is the minefield theory. It says the reason so many animals tend to hang motionless in the deep, even fish, is to avoid setting off light explosions that would expose them to their enemies - their predators or their prey. Life in the midwater, in this view, is a tense affair (though the denizens do not know it) in which everyone is waiting stealthily in the dark, moving slowly if at all, watching and waiting for someone to turn on a light and for something to happen. — Robert Kunzig

Primates stand at a turning point in the course of evolution. Primates are to the biologist what viruses are to the biochemist. They can be analysed and partly understood according to the rules of a simpler discipline, but they also present another level of complexity: viruses are living chemicals, and primates are animals who love and hate and think. — Alison Jolly

Long ago the signalling had become no more than a meaningless ritual, now maintained by an animal which had forgotten to learn and a robot which had never known to forget. — Arthur C. Clarke

Perhaps we should rejoice that people's emotions aren't designed for the good of the group. Often the best way to benefit one's group is to displace, subjugate, or annihilate the group next door. Ants in a colony are closely related, and each is a paragon of unselfishness. That's why ants are one of the few kinds of animal that wage war and take slaves. When human leaders have manipulated or coerced people into submerging their interests into the group's, the outcomes are some of the history's worst atrocities. — Steven Pinker

Blake expressed some doubt as to whether God had made the tiger. But the tiger is in many ways an admirable animal. We have now to ask if God made the tapeworm. And it is questionable whether an affirmative answer fits in either with what we know about the process of evolution or what many of us believe about the moral perfection of God. — John B. S. Haldane

The transpersonal experiences revealing the Earth as an intelligent, conscious entity are corroborated by scientific evidence. Gregory Bateson, who created a brilliant synthesis of cybernetics, information and systems theory, the theory of evolution, anthropology, and psychology came to the conclusion that it was logically inevitable to assume that mental processes occurred at all levels in any system or natural phenomenon of sufficient complexity. He believed that mental processes are present in cells, organs, tissues, organisms, animal and human groups, eco-systems, and even the earth and universe as a whole. — Stanislav Grof

The human form was never [formed] to beget children. This tendency among people to cohabit is nothing but animal instinct inherited from all the previous lives of evolution from the stone to the human form. — Meher Baba

First Law
In every animal which has not passed the limit of its development, a more frequent and continuous use of any organ gradually strengthens, develops and enlarges that organ, and gives it a power proportional to the length of time it has been so used; while the permanent disuse of any organ imperceptibly weakens and deteriorates it, and progressively diminishes its functional capacity, until it finally disappears.
Second Law
All the acquisitions or losses wrought by nature on individuals, through the influence of the environment in which their race has long been placed, and hence through the influence of the predominant use or permanent disuse of any organ; all these are preserved by reproduction to the new individuals which arise, provided that the acquired modifications are common to both sexes, or at least to the individuals which produce the young. — Jean-Baptiste Lamarck

People who believe in God think God has put human beings on earth because they think human beings are the best animal, but human beings are just an animal and they will evolve into another animal, and that animal will be cleverer and it will put human beings into a zoo, like we put chimpanzees and gorillas into a zoo. Or human beings will all catch a disease and die out or they will make too much pollution and kill themselves, and then there will only be insects in the world and they will be the best animal. — Mark Haddon

Jim Crow repeated the old strategies of the reptilian powers of the air: to convince human beings simultaneously and paradoxically that they are gods and animals. In the Garden, after all, the snake approached God's image-bearer, directing her as though he had dominion over her (when it was, in fact, the other way around). He treated her as an animal, and she didn't even see it. At the same time, the old dragon appealed to her to transcend the limits of her dignity. If she would reach for the forbidden, she would be "like God, knowing good and evil." He suggested that she was more than a human; she was a goddess. — Russell D. Moore

It is a more rational belief that man may become a brute than that a brute may become a man; and it is an easier faith that plants and animals may dwindle down into an elemental atom, than that this atom should embrace in its organization, and evolve, all the noble forms of vegetable, animal, and intellectual life. — David Brewster

But there is no agency in evolution; it is inadvertent. We survived, modified, and multiplied, just like any animal alive today, and out of the wildly dodgem course we took, language arose. — Christine Kenneally

We know from the truths of evolution and ecology that we are all related and interdependent. Anthropomorphism (crediting animals with human emotions and traits) is, however, outdated. Rather we know that we are like animals. — Michael Fox

Evolution was in a strange mood when that creation came along ... It makes one wonder just where the plant world leaves off and the animal world begins. — John Colton

Only God was able to create a free creature, and freedom could only arise by the act of creation. Freedom is not the result or product of evolution. Freedom and product are disparate ideas. God does not produce or construct. He creates. We used to say the same for artists, for the artist who constructs does not create a personality but rather a poster of man. A personality cannot be constructed. Maybe sooner or later, during this century or after a million years of continued civilization, man will succeed in constructing an imitation of himself, a kind of robot or monster, something similar to its constructor. This human-looking monster may look very much like man, but one thing is certain: it will never have freedom. Without a divine touch, the result of evolution would not have been man, but rather a developed animal, a super-animal, a creature with a human body and intelligence but without a heart and personality. — Alija Izetbegovic

Man is a glorious and unique species of animal. The species originated by evolution.... Future evolution could raise man to superb heights as yet hardly glimpsed, but it will not automatically do so. As far as can now be foreseen, evolutionary degeneration is at least as likely in our future as is further progress.The only way to ensure a progressive evolutionary future for mankind is for man himself to take a hand in the process. Although much further knowledge is needed, it is unquestionably possible for man to guide his own evolution (within limits) along desirable lines. But the great weight of the most widespread...beliefs and institutions is against even attempting such guidance. ["Man's evolutionary future," 1960, p. 134.] — George Gaylord Simpson

It is a total mystery how we evolved minds capable of piloting cars through wild maneuvers using a wrist to steep while shouting at a cell phone. The creationists are fools for focusing on animal evolution. Darwin explains nature! He has more difficulty explaining us. — David Brin

It turned out to be a young Dasypus novemcinctus, a nine-banded armadillo, about the size of a small loaf of bread. Although they were becoming more common in Texas, I'd never seen one up close before. Anatomically speaking, it resembled the unhappy melding of an anteater (the face), a mule (the ears), and a tortoise (the carapace). I thought it overall an unlucky creature in the looks department, but Granddaddy once said that to apply a human definition of beauty to an animal that had managed to thrive for millions of years was both unscientific and foolish. — Jacqueline Kelly

Take the entire 4.5-billion-year history of the earth and scale it down to a single year, with January 1 being the origin of the earth and midnight on December 31 being the present. Until June, the only organisms were single-celled microbes, such as algae, bacteria, and amoebae. The first animal with a head did not appear until October. The first human appears on December 31. We, like all the animals and plants that have ever lived, are recent crashers at the party of life on earth. — Neil Shubin

If animal history has been a history of evolution, then the history of mankind is one of retrogression. Hooray for monsters! Monsters are the great embodiments of the weak. — Kobo Abe

An ancient predator walks amongst us. He is neither man nor animal. He is the by passer of evolution, a blight on creationism, and the nightmare of man given form. — Robert G. Moons

Man is a clothed animal; almost. — Ahmed Mostafa

I want to put it back together now, this artistic expression that contains religious feeling. I want to investigate: What was the origin? What's happened in the human mind? Can we trace back the moment of the creation of human consciousness? And why did only humans gain consciousness, not other animals? So, evolution? I don't know whether or not I can believe evolution. Maybe we wait for another 100,000 years and then apes get consciousness. — Hiroshi Sugimoto

The old tyrants invoked the past; the new tyrants will invoke the future evolution has produced the snail and the owl; evolution can produce a workman who wants no more space than a snail, and no more light than an owl. The employer need not mind sending a Kaffir to work underground; he will soon become an underground animal, like a mole. He need not mind sending a diver to hold his breath in the deep seas; he will soon be a deep-sea animal. Men need not trouble to alter conditions, conditions will so soon alter men. The head can be beaten small enough to fit the hat. Do not knock the fetters off the slave; knock the slave until he forgets the fetters. — G.K. Chesterton

What if I'm just a sick animal? A creature shuffled into existence here by the random whims of evolution. Nothing more. An existence totally without inherent meaning, totally without purpose. What — Tim McBain

THERE IS ONE MORE POINT to be made about animal minds and evolution. Evolution is not a progressive force. Although it was once thought that there was a scale of nature or a Great Chain of Being, with all the forms of life ascending in some orderly, preordained fashion - from jellyfish to fish to birds to dogs and cats to us - this is not the case. We are not the culmination of all these "lesser" beings; they are not lesser and we are not the pinnacle of evolution. — Virginia Morell

Human spoken language seems to be
adventitious. The exploitation of organ systems with other functions for communication in humans is also indicative of the comparatively recent evolution of our linguistic abilities. — 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

The shrimp's protein and ours are not exactly the same, but they're so
similar that if you turned up in court and tried to convince a judge that your
version was not a badly concealed plagiarism, you'd be very unlikely to win.
In fact, you'd be a laughing stock, for rhodopsin is not restricted to vent shrimp
and humans but is omnipresent throughout the animal kingdom.... Trying to persuade a judge that your rhodopsin is not plagiarised
would be like trying to clajm that your television set is fundamentally different
from everyone else's, just because it's bigger or has a flat screen. — Nick Lane

If ... deceit is fundamental to animal communication, then there must be strong selection to spot deception and this ought, in turn, to select for a degree of self-deception, rendering some facts and motives unconscious so as not to betray - by the subtle signs of self-knowledge - the deception being practiced.' Thus, 'the conventional view that natural selection favors nervous systems which produce ever more accurate images of the world must be a very naive view of mental evolution. — Robert Trivers

...the great experiences which form him, arise out of the discontinuity and disharmony between man and the world. Particularly in great personalities, we see how much of their beauty and excellence is really due to trials suffered earlier at the hands of the world. Beauty--as many have recognized--is pain suffered and transformed. Because the animal is adapted to its environment, it is denied the possibility of developing inward maturity and greatness. As an individual creature it cannot grow beyond the limits of its kind; and again, at death, it falls back with its capacities into the group Ego, from which its soul was something like an offshoot or a patrol sent out on reconnaissance. — Hermann Poppelbaum

The ancestors of the higher animals must be regarded as one-celled beings, similar to the Amoebae which at the present day occur in our rivers, pools, and lakes. The incontrovertible fact that each human individual develops from an egg, which, in common with those of all animals, is a simple cell, most clearly proves that the most remote ancestors of man were primordial animals of this sort, of a form equivalent to a simple cell. When, therefore, the theory of the animal descent of man is condemned as a 'horrible, shocking, and immoral' doctrine, tho unalterable fact, which can be proved at any moment under the microscope, that the human egg is a simple cell, which is in no way different to those of other mammals, must equally be pronounced 'horrible, shocking, and immoral. — Ernst Haeckel

Pliny suggested that the ostrich, then newly discovered, was the result of a cross between a giraffe and a gnat. (It would, I suppose, have to be a female giraffe and a male gnat.) In practice there must be many such crosses which have not been
attempted because of a certain understandable lack of motivation. — Carl Sagan

While all living things affect the evolution of other living things simply by virtue of trying to stay alive, humans interact with the biological evolution of other species in a much more complex and powerful fashion because of one ability: language. Nothing occurs on the human scale without language. No language means no agriculture, no animal farming, no science. — Christine Kenneally

The generative function is strictly nothing but an animal one, and can never be anything else. True spirituality demands its utter extirpation; and while its proper exercise for the continuation of the human race, in the semi-animal stage of its evolution, may not be considered sinful, its misuse, in any way, is fraught with the most terrible consequences physically, psychically and spiritually; and the forces connected with it are used for abnormal purposes only in the foulest practices of sorcery, the inevitable result of which is moral death - the annihilation of the individuality. — James Morgan Pryse

Historians are wont to name technological advances as the great milestones of culture, among them the development of the plow, the discovery of smelting and metalworking, the invention of the clock, printing press, steam power, electric engine, lightbulb, semiconductor, and computer. But possibly even more transforming than any of these was the recognition by Greek philosophers and their intellectual descendants that human beings could examine, comprehend, and eventually even guide or control their own thought process, emotions, and resulting behavior.
With that realization we became something new and different on earth: the only animal that, by examining its own cerebration and behavior, could alter them. This, surely, was a giant step in evolution. Although we are physically little different from the people of three thousand years ago, we are culturally a different species. We are the psychologizing animal. — Morton Hunt

There were two Republican responses to the State of the Union. So if you watched the whole night, it was kind of evolution in reverse. You have Obama, then Paul Ryan, and then Michele Bachmann. Then Animal Planet had a squirrel monkey give his take. — Bill Maher

Man has risen, not fallen. He can choose to develop his capacities as the highest animal and to try to rise still farther, or he can choose otherwise. The choice is his responsibility, and his alone. There is no automatism that will carry him upward without choice or effort and there is no trend solely in the right direction. Evolution has no purpose; man must supply this for himself. The means to gaining right ends involve both organic evolution and human evolution, but human choice as to what are the right ends must be based on human evolution. — George Gaylord Simpson

But then arises the doubt, can the mind of man, which has, as I fully believe been developed from a mind as low as that possessed by the lowest animal, be trusted when it draws such grand conclusions? — Charles Darwin

We still have a long way to go. But we are moving in the right direction. If only we can overcome cruelty, to human and animal, with love and compassion we shall stand at the threshold of a new era in human moral and spiritual evolution - and realize, at last, our most unique quality: humanity. — Jane Goodall

Since the white man says he came from the evolution of animals, well, maybe the black man didn't. The white man has made so many errors in the handling of people that maybe he did come from a gorilla or a fish and crawl up on the sand and then into the trees. Of course, evolution doesn't take God into consideration. I don't think people learned to do all the things they do through evolution. — Charles Mingus

We have vexed and bothered every plant and every animal on every continent. — Diane Ackerman

I have an odd theory on happiness, and it bothers people. My general theory is that happiness is a reward for an animal doing what it should be doing. So if a horse runs, it feels happy. Or if you are too thin, you can't be happy, because evolution wants you to be tense and anxious, trying to wake up in the morning looking for food. — James D. Watson

Brambles, in particular, protect and nourish young fruit trees, and on farms bramble clumps (blackberry or one of its related cultivars) can be used to exclude deer and cattle from newly set trees. As the trees (apple, quince, plum, citrus, fig) age, and the brambles are shaded out, hoofed animals come to eat fallen fruit, and the mature trees (7 plus years old) are sufficiently hardy to withstand browsing. Our forest ancestors may well have followed some such sequences for orchard evolution, assisted by indigenous birds and mammals. — Bill Mollison

Animals are footprints of God. — Martin Luther

The following proposition seems to me in a high degree probable - namely, that any animal whatever, endowed with well-marked social instincts, the parental and filial affections being here included, would inevitably acquire a moral sense or conscience, as soon as its intellectual powers had become as well, or nearly as well developed, as in man. For, firstly, the social instincts lead an animal to take pleasure in the society of its fellows, to feel a certain amount of sympathy with them, and to perform various services for them. — Charles Darwin

In fact, public speaking anxiety may be primal and quintessentially human, not limited to those of us born with a high-reactive nervous system. One theory, based on the writings of the sociobiologist E.O. Wilson, holds that when our ancestors lived on the savannah, being watched intently meant only one thing: a wild animal was stalking us. And when we think we're about to be eaten, do we stand tall and hold forth confidently? No. We run. In other words, hundreds of thousands of years of evolution urge us to get the hell off the stage, where we can mistake the gaze of the spectators for the glint in a predator's eye. — Susan Cain

Man is developed from an ovule, about 125th of an inch in diameter, which differs in no respect from the ovules of other animals. — Charles Darwin

In comparison with capitalism, which reconstituted man as an economic animal; in comparison with Marxism, which found man an object made up of organized matter; in comparison with catholicism, which saw him as the unwitting plaything of an imperious unseen power (the Divine Will); in comparison with dialectical materialism, which saw him as unwitting plaything of the deterministic evolution of the means of production- existentialism made man a god — Ali Shariati

It was none the less a perfectly ordinary horse, such as convergent evolution has produced in many of the places that life is to be found. They have always understood a great deal more than they let on. It is difficult to be sat on all day, every day, by some other creature, without forming an opinion about them. — Douglas Adams
