Species Quotes

Nature is indifferent to the survival of the human species, including Americans. ~ Adlai E. Stevenson

Men and women are brothers and sisters; they are not of different species; and what need be obtained to know both, but to allow for different modes of education, for situation and constitution, or perhaps I should rather say, for habits, whether good or bad. ~ Samuel Richardson

Is it not strange how humans will resort to the most inhumane of actions as the first plausible solution? Why are we such a feral bloodthirsty species when we are supposedly the enlightened ones? Are we guardians ... or just mindless butchers? ~ Dimitri Zaik

It is a rather amazing fact that, of the very many dimensions along which the genital activity of one person can be differentiated from that of another (dimensions that include preference for certain acts, certain zones or sensations, certain physical types, a certain frequency, certain symbolic investments, certain relations of age or power, a certain species, a certain number of participants, and so on) precisely one, the gender of the object choice, emerged from the turn of the century, and has remained, as THE dimension denoted by the now ubiquitous category of 'sexual orientation. ~ Eve Kosofsky Sedgwick

I don't think of kids as a lower form of the human species. ~ John Hughes

Some men, as they age, grow kinder. I am not one of those, for I have seen how the cosmere can mistreat the innocent - and that leaves me disinclined toward kindness. Some men, as they age, grow wiser. I am not one of those, for wisdom and I have always been at cross-purposes, and I have yet to learn the tongue in which she speaks. Some men, as they age, grow more cynical. I, fortunately, am not one of those. If I were, the very air would warp around me, sucking in all emotion, leaving only scorn.
Other men...other men, as they age, merely grow stranger. I fear that I am one of those. I am the bones of a foreign species left drying on the plain that was once, long ago, a sea. A curiosity, perhaps a reminder, that all has not always been as it is now. ~ Brandon Sanderson

A satirist, often in danger himself, has the bravery of knowing that to withhold wit's conjecture is to endanger the species. ~ Penelope Gilliatt

So if you hear something in this book that sounds like advocacy of a particular political point of view, please reject the notion. My interest in issues is merely to point out how badly we're doing, not to suggest a way we might do better.
Don't confuse me with those who cling to hope. I enjoy describing how things are, I have no interest in how they ought to be. And I certainly have no interest in fixing them. I sincerely believe that if you think there's a solution, you're part of the problem.
My motto: Fuck Hope.
P.S. In case you're wondering, personally I'm a joyful individual, I had a long happy marriage and a close and loving family, my career has turned out better than I ever dreamed, and it continues to expand. I'm a personal optimist, but a skeptic about all else. What may sound to some like anger, is really nothing more than sympathetic contempt. I view my species with a combination of wonder and pity, and I root for its destruction. And please don't confuse my point of view with cynicism–the real cynics are the ones who tell you everything's gonna be all right.
And P.P.S., by the way, if by some chance you folks do manage to straighten things out and make everything better, I still don't wish to be included. ~ George Carlin

{On to contributions to evolutionary biology of 18th century French scientist, Georges-Louis Leclerc, Comte de Buffon}

He was not an evolutionary biologist, yet he was the father of evolutionism. He was the first person to discuss a large number of evolutionary problems, problems that before Buffon had not been raised by anybody.... he brought them to the attention of the scientific world.

Except for Aristotle and Darwin, no other student of organisms [whole animals and plants] has had as far-reaching an influence.

He brought the idea of evolution into the realm of science. He developed a concept of the "unity of type", a precursor of comparative anatomy. More than anyone else, he was responsible for the acceptance of a long-time scale for the history of the earth. He was one of the first to imply that you get inheritance from your parents, in a description based on similarities between elephants and mammoths. And yet, he hindered evolution by his frequent endorsement of the immutability of species. He provided a criterion of species, fertility among members of a species, that was thought impregnable. ~ Ernst W. Mayr

Kitsch is: a species of beauty, which, as it is florid and superficial, pleases at first; but soon palls upon the taste, and is rejected with disdain, at least rated at much lower value. ~ David Hume

We must recognize that we're all part of a web of life around the world. Anytime you extinguish a species, the consequences are serious. ~ Gaylord Nelson

We may think of volcanic islands like Ascension as unusual because their recent origin and remoteness mean their ecosystems are made up of a motley crew of mariner migrants. But much of the world is like that. Nature is constantly in flux, and few ecosystems go back very far. Only ten thousand years ago, much of Europe and North America were covered in thick ice. All soil had been scraped away and with it most forms of life. Everything we see today in these former glaciated zones has either returned or arrived for the first time since the ice retreated.
Looked at from this perspective, the spread of alien species today is merely a continuation of a natural process of the colonization begun when the ice retreated. A broad time horizon shows there is no such thing as a native species. All lodgings are temporary and all ecosystems in a constant flux, the victims of circumstance and geological accident. As the pioneer British ecologist Charles Elton argued, "Were it not for the ice age, we [in Britain] should probably have wonderful mixed forests with wild magnolias and laurels and epiphytic orchids, such as . . . in China. ~ Fred Pearce

In Buddhism, we talk of meditation as an act of awakening, to be awake to the fact that the earth is in danger and living species are in danger. ~ Nhat Hanh

Interesting, but she could see that the boy didn't have a single lie in him. A very rare condition, especially for the male of the species. ~ Alice Hoffman

Honey, you [Michael Jackson] gotta pick a race first. All of a sudden you're a black man, then you're Diana Ross, now you're Audrey Hepburn. Then he's got the little beard going on. He's like Lord of the Rings, the entire cast. Michael's about to jump species. ~ Robin Williams

When a baby is born the mother in particular enters into a new larger relationship with the world. She has become connected to all people. She is part of keeping us on earthnot the "us" comprised of individuals but the species itself. By protecting this one baby this gift a mother accepts life's clearest responsibility. ~ Gavin De Becker

We, as Americans, at least - I mean, I love my country - but we're so self-righteous sometimes, in terms of, like, our nationality, our country. But we're people from somewhere else; the true 'Americans' are the original peoples. It's funny, but we're a very territorial species. ~ Peter Dinklage

The construction of the nuclear doomsday machine - and its continued maintenance and development since the mid-twentieth century - is surely one of the most astounding acts of collective insanity in the history of the human species. ~ Richard L. Currier

Some of these species that are now no longer with us were killed off by a fungal disease that was moved around the planet by people. ~ Elizabeth Kolbert

I want to reach inside and pluck the darkness out of her ~ Mindy McGinnis

Rather, although belief may be adequate for explaining the behavior of individual animals - an animal which believes that p will behave no differently from an animal which knows that p - talk of knowledge is necessary once one begins to look at explaining the cognitive capacities of a species. ~ Hilary Kornblith

It is a part of our office to stand uncloaked, masked, sword bared, upon the scaffold for a long time before the client is brought out. Some say this is to symbolize the unsleeping omnipresence of justice, but I believe the real reason is to give the crowd a focus, and the feeling that something is about to take place. A crowd is not the sum of the individuals who compose it. Rather it is a species of animal, without language or real consciousness, born when they gather, dying when they depart. Before the Hall of Justice, a ring of dimarchi surrounded the scaffold with their lances, and the pistol their officer carried could, I suppose, have killed fifty or sixty before someone could snatch it from him and knock him to the cobblestones to die. Still it is better to have a focus, and some open symbol of power.
Wolfe, Gene (1994-10-15). Shadow & Claw: The First Half of 'The Book of the New Sun' (p. 184). Tom Doherty Associates. Kindle Edition. ~ Gene Wolfe

Merlin: "Grown-ups have developed an unpleasant habit lately, I notice, of comforting themselves for their degradation by pretending that children are childish. I trust we are free of this?"
Arthur: "Everybody knows that children are more intelligent than their parents."
Merlin: "You and I know it, but the people who are going to read this book do not.
Our readers of that time ( ... ) have exactly three ideas in their magnificent noodles. The first is that the human species is superior to others. The second, that the twentieth century is superior to other centuries. And the third, that human adults of the twentieth century are superior to their young. ( ... ) ~ T.H. White

What is there about the notion of a person, at law, that makes every living member of the species Homo sapiens a person, irrespective of their mental capacities, but excludes every nonhuman animal - again, irrespective of their mental capacities? ~ Peter Singer

Perceptual reality is different for different species. In certain species it is a mode of observation, so what we call scientific fact is actually not ultimate truth, it is perceptual experience, and it's a mode of observation. ~ Deepak Chopra

The order Chiroptera (the "hand-wing" creatures) encompasses 1,116 species, which amounts to 25 percent of all the recognized species of mammals. To say again: One in every four species of mammal is a bat. Such ~ David Quammen

People generally will soon understand that writers should be judged, not according to rules and species, which are contrary to nature and art, but according to the immutable principles of the art of composition, and the special laws of their individual temperaments. ~ Victor Hugo

We have really, that I know of, no philosophical basis for high and low. Moreover, the vegetable kingdom does not culminate, as the animal kingdom does. It is not a kingdom, but a common-wealth; a democracy, and therefore puzzling and unaccountable from the former point of view. ~ Asa Gray

For many Westerners, "it's natural" seems to mean "it's good." This view is wrong and comes from shopping in supermarkets and living in landscaped environments. Plants evolved toxins to deter animals, fungi, and bacteria from eating them. The list of "natural" foods that need processing to detoxify them goes on and on. Early potatoes were toxic, and the Andean peoples ate clay to neutralize the toxin. Even beans can be toxic without processing. In California, many hunter-gatherer populations relied on acorns, which, similar to manioc, require a labor intensive, multiday leaching process. Many small-scale societies have similarly exploited hardy, tropical plants called cycads for food. But cycads contain a nerve toxin. If not properly processed, they can cause neurological symptoms, paralysis, and death. Numerous societies, including hunter-gatherers, have culturally evolved an immense range of detoxification techniques for cycads. By contrast with our species, other animals have far superior abilities to detoxify plants. Humans, however, lost these genetic adaptations and evolved a dependence on cultural know-how, just to eat. ~ Joseph Henrich

Light will be thrown on the origin of man and his history. ~ Charles Darwin

There are six billion egos living on this planet. Can you not see why the world is in such a sorry state? Can you not see why we are destroying Heaven on Earth for our own short-term gain? Can you not see why the tiger and the gorilla are facing extinction, along with countless other species? Can you not see why there is so much injustice, abuse, greed, cruelty, and inequality upon this planet? We get along with those who share the same set of illusions. It is called collusion. They are our friends. We declare war on those who dare to believe in another set of illusions. They are our enemies. Religion, and particularly religious fundamentalism, is the most obvious and dangerous example. Nationalism is another. "Me! Me! Me!" "Mine! Mine! Mine!" "I'm right. I'm right. I'm right." "How can I use this or make use of this?" "What's in it for me?" You ~ Mary Bruggeman

A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet. One of the great revelations of the age of space exploration is the image of the earth finite and lonely, somehow vulnerable, bearing the entire human species through the oceans of space and time. ~ Carl Sagan

Given the brevity of our time here, it does seem likely that our species, too, must have at best a blinkered understanding of the shape of things, the import of certain events and what distinguishes 'good' from 'bad' luck. ~ Karen Russell

Nature is a collective idea, and, though its essence exist in each individual of the species, can never in its perfection inhabit a single object. ~ Henry Fuseli

Greater self-awareness," he'd told Rocky on a night when sleep wouldn't come, "doesn't make a species any happier, pal. If it did, we'd have fewer psychiatrists and barrooms ... ~ Dean Koontz

The secret to battling cancer, then, is to find means to prevent these mutations from occurring in susceptible cells, or to find means to eliminate the mutated cells without compromising normal growth. The conciseness of that statement belies the enormity of the task. Malignant growth and normal growth are so genetically intertwined that unbraiding the two might be one of the most significant scientific challenges faced by our species. Cancer is built into our genomes: the genes that unmoor normal cell division are not foreign to our bodies, but rather mutated, distorted versions of the very genes that perform vital cellular functions. And cancer is imprinted in our society: as we extend our life span as a species, we inevitably unleash malignant growth (mutations in cancer genes accumulate with aging; cancer is thus intrinsically related to age). If we seek immortality, then so, too, in a rather perverse sense, does the cancer cell. ~ Siddhartha Mukherjee

We pride ourselves on being the only species that understands the concept of risk, yet we have a confounding habit of worrying about mere possibilities while ignoring probabilities, building barricades against perceived dangers while leaving ourselves exposed to real ones. ~ Jeffrey Kluger

Man makes history; woman is history. The reproduction of the species is feminine: it runs steadily and quietly through all species, animal or human, through all short-lived cultures. It is primary, unchanging, everlasting, maternal, plantlike, and cultureless. If we look back we find that it is synonymous with life itself. ~ Oswald Spengler

Extinction, the irrevocable loss of a species, causes pain that can never find relief. It is an ache that will pass from generation to generation for the rest of human history. ~ Callum Roberts

Story of our species ... everyone knows it's coming, but not so soon. ~ Michael Crichton

Certainly amongst all devotions, after that of receiving the sacraments, that of adoring Jesus in the Blessed Sacrament holds first place, is most pleasing to God, and most useful to ourselves. Do not then, O devout soul, refuse to begin this devotion; and forsaking the conversation of men, dwell each day, from this time forward, for at least half or quarter of an hour, in some church, in the presence of Jesus Christ under the sacramental species. Taste and see how sweet is the Lord. ~ Alphonsus Liguori

I was trying to discover examples of a living restoration, trying to go beyond discussions about correct historic colors, materials, and techniques.
I looked to the past for guidance, to find the graces we need to save. I want to be an importer. This is not nostalgia; I am not nostalgic. I am not looking for a way back. "From where will a renewal come to us, to us who have devastated the whole earthly globe?" asked Simone Weil. "Only from the past if we love it."
What I am looking for is the trick of having the same ax twice, for a restoration that renews the spirit, for work that transforms the worker. We may talk of saving antique linens, species, or languages; but whatever we are intent on saving, when a restoration succeeds, we rescue ourselves.
Howard Mansfield, The Same Ax Twice: Restoration and Renewal in a Throwaway Age ~ Howard Mansfield

There's racism and sexism and ageism and all sorts of idiocies. But bad news is not news. We've had bad news as a species for a long time. We've had slavery and human sacrifice and the holocaust and brutalities of such measure. ~ Maya Angelou

The reproduction of mankind is a great marvel and mystery. Had God consulted me in the matter, I should have advised him to continue the generation of the species by fashioning them out of clay. ~ Martin Luther

Nobody, I believe, will deny, that we are to form our judgment of the true nature of the human mind, not from sloth and stupidity of the most degenerate and vilest of men, but from the sentiments and fervent desires of the best and wisest of the species. ~ Robert B. Leighton

The intuitive connection children feel with animals can be a tremendous source of joy. The unconditional love received from pets, and the lack of artifice in the relationship, contrast sharply with the much trickier dealings with members of their own species. ~ Frans De Waal

You see the barren earth when We send water down upon it, stirring, sprouting and producing every sort of lovely species.* That because God is the Truth: He revives the dead and is capable of everything!
Quran-AlHaj(5,6) ~ Anonymous

In nature, creatures never ended the lives of others except to survive. To women, abortion was self-defense and preservation of the species. Abortion was not a fancy borne out of the female mind. Abortion was instinct beyond ideas. Abortion was fear (the cat that devours its litter when a predator nears). ~ Ana Castillo

we, as a species, now stand at a crossroads. We can face the possibility of our own extinction and work to avert it, or we can follow the more traditional path of earth's organisms and fall blindly over the edge. If there's one trait that characterizes human beings, it's the will to survive. This, I believe, will motivate us to work with the natural world rather than oppose it, which is all we need to do to give the children of earth - of all species - the opportunity to thrive. ~ Alexandra Morton

Established species are evolving so slowly that major transitions between genera and higher taxa must be occurring within small rapidly evolving populations that leave NO LEGIBLE FOSSIL RECORD. ~ Steven M. Stanley

We are one species out of a billion ~ Hiba Fatima Ahmad

The whole [scientific] process resembles biological evolution. A problem is like an ecological niche, and a theory is like a gene or a species which is being tested for viability in that niche. ~ David Deutsch

The Tree of Life was an ancient symbol of interconnection, fertility, and eternal life - precisely because of this legendary tree's fruit. Fruit is part of our essence, a basic element of who we are. We cannot survive without fruit on this planet. It outweighs the nutrition of any other food. Yet the current "health" movement toward low-carb diets has put fruit on the endangered species list, with the goal of making it extinct. Is this denial? Ignorance? Foolishness? We're not talking about uneducated people who are driving the trend. We're talking about smart, highly intelligent professionals with advanced degrees in medicine and nutrition. If they're advising patients to shun fruit, it must be because of their training, the misinformation out there, or their own selective interests. Have you heard of book burning? If the anti-sugar war keeps up its momentum, fruit trees will be next to go up in flames. ~ Anthony William

The sacrifice of personal existence is necessary to secure the preservation of the species. ~ Adolf Hitler

Humans, unlike Jedi, are powerfully afraid of rejection. We do not survive well alone, so humans as a species are especially vulnerable to thoughts that make us afraid the rest of the "tribe" will desert us to die a sad, lonely death. ~ Stephen Richards

Each person is an idiom unto himself, an apparent violation of the syntax of the species. ~ Gordon W. Allport

The earth left to its own natural fertility and covered with immense woods, that no hatchet ever disfigured, offers at every step food and shelter to every species of animals. Men, dispersed among them, observe and imitate their industry, and thus rise to the instinct of beasts; with this advantage, that, whereas every species of beasts is confined to one peculiar instinct, man, who perhaps has not any that particularly belongs to him, appropriates to himself those of all other animals, and lives equally upon most of the different aliments, which they only divide among themselves; a circumstance which qualifies him to find his subsistence, with more ease than any of them. ~ Jean-Jacques Rousseau

The human in what it is objectively ever since its beginning is two, two who are different. Each part of what constitutes the unity of the human species corresponds to a proper being and a proper Being, to an identity of one's own. In order to carry out the destiny of humanity, the man-human and the woman-human each have to fulfill what they are and at the same time realize the unity that they constitute. ~ Luce Irigaray

At New York City's Rose Center of Earth and Space, we display a timeline spiral of the Universe that begins at the Big Bang and unfolds 13.8 billion years. Uncurled, it's the length of a football field. Every step you take spans 50 million years. You get to the end of the ramp, and you ask, where are we? Where is the history of our human species? The entire period of time, from a trillion seconds ago to today, from graffiti-prone cave dwellers until now, occupies only the thickness of a single strand of human hair, which we have mounted at the end of that timeline. You think we live long lives, you think civilizations last a long time, but not from the view of the cosmos itself. ~ Neil DeGrasse Tyson

We are a wretched, petty species, and we have been given power to destroy ourselves with. ~ Wildbow

Each of us is several, is man, is a profusion of selves. So that the self who disdains his surroundings is not the same as the self who suffers or takes joy in them. In the colony of our being there are many species of people who think and feel in different ways. ~ Pascal Mercier

It is a well-known fact that of all the species on earth Homo sapiens is among the most adaptable. Settle a tribe of them in a desert and they will wrap themselves in cotton, sleep in tents, and travel on the backs of camels; settle them in the Arctic and they will wrap themselves in sealskin, sleep in igloos, and travel by dog-drawn sled. And if you settle them in a Soviet climate? They will learn to make friendly conversation with strangers while waiting in line; they will learn to neatly stack their clothing in their half of the bureau drawer; and they will learn to draw imaginary buildings in their sketchbooks. That is, they will adapt. ~ Amor Towles

The human species was not born into a market economy. Bees won't sell you honey if you offer them an electronic funds transfer. The human species imagined money into existence, and it exists - for us, not mice or wasps - because we go on believing in it. ~ Eliezer Yudkowsky

One of the basic steps in saving a threatened species is to learn more about it: its diet, its mating and reproductive processes, its range patterns, its social behavior. ~ Dian Fossey

To this point in his life, Jake had been aware of only three feelings about his father: puzzlement, fear, and a species of weak, confused love. Now a fourth and fifth surfaced. One was anger; the other was disgust. ~ Stephen King

There are many ways to make the most of your time on the planet, and propagation of the species is just one of them. If you're convinced that it's the key to your happiness, there are routes open to you, whether with the help of modern medical science, marrying into a readymade one, or through fostering and adoption. ~ Mariella Frostrup

First Emma. Now Thad. Regin was sick and tired of non-evil vampiric creatures messing with her millennium's worth of scathing animosity for their species... ~ Kresley Cole

A schoolteacher or professor cannot educate individuals, he educates only species. ~ Georg C. Lichtenberg

The other part of seeing what is on the block is appreciating how limited our own view is. We are limited by our sensory abilities, by our species membership, by our narrow attention - at least the last of which can be overcome. ~ Alexandra Horowitz

The only profit from their sojourn on Earth would be the memory of this mad species, which had somehow become intelligent without ever learning how to understand themselves. ~ Orson Scott Card

Dogs and humans are symbiotic species. We need each other. ~ Cynthia Heimel

I'd like to share a revelation that I've had during my time here. It came to me when I tried to classify your species. I realized that you're not actually mammals. Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment, but you humans do not. You move to an area, and you multiply, and multiply, until every natural resource is consumed. The only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Human beings are a disease, a cancer of this planet, you are a plague, and we are the cure. ~ Agent Smith

The combined effects of mutation, natural selection and the random process of genetic drift cause changes in the composition of a population. Over a sufficiently long period of time, these cumulative effects alter the population's genetic make-up, and can thus greatly change the species' characteristics from those of its ancestors. ~ Brian Charlesworth

It's a funny thing about the modern world. You hear girls in the toilets of clubs saying, "Yeah, he fucked off and left me. He didn't love me. He just couldn't deal with love. He was too fucked up to know how to love me." Now, how did that happen? What was it about this unlovable century that convinced us we were, despite everything, eminently lovable as a people, as a species? What made us think that anyone who fails to love us is damaged, lacking, malfunctioning in some way? And particularly if they replace us with a god, or a weeping madonna, or the face of Christ in a ciabatta roll
then we call them crazy. Deluded. Regressive. We are so convinced of the goodness of ourselves, and the goodness of our love, we cannot bear to believe that there might be something more worthy of love than us, more worthy of worship. Greeting cards routinely tell us everybody deserves love. No. Everybody deserves clean water. Not everybody deserves love all the time. ~ Zadie Smith

Yes, the worst parasites. We reproduce with no internal limitations. We consume and destroy and make war. We have no predator except ourselves, and left unchecked we destroy ourselves every time. And we destroy the planet along with us. Humankind is the thing that must be contained. Man must be checked. We were nature's mistake - the only species worth extinction is our very own. ~ Ryan Winfield

It's a natural law (or supernatural, if you're so inclined) that weird things appear where people tend to disappear. African jungles, Pacific islands, Himalayan wastelands - wherever expeditionary parties go missing, that's where lost species, Stonehengey stone idols, the flitting shadows of yetis, and ancient, unsurrendering Japanese soldiers are sure to pop up. The ~ Christopher McDougall

Human activity is having a major impact on the planet. We consume or have diverted a large proportion of the productivity of the land and oceans. Our hunger for land crowds out fellow species. Our waste products pollute the waters, warm the atmosphere and acidify the oceans. ~ Ian Goldin

In one way, traveling has narrowed my mind. What I have discovered is something very ordinary and unexciting, which is that humans are the same everywhere and that the degree of variation between members of our species is very slight. This is of course an encouraging finding; it helps arm you against news programs back home that show seething or abject masses of either fanatical or torpid people. In another way it is a depressing finding; the sorts of things that make people quarrel and make them stupid are the same everywhere. ~ Christopher Hitchens

But there was also a notable decline in many quarters of the world of jingoist rhetoric and puerile self-congratulatory nationalism. There was a sense of the human species, billions of tiny beings spread over the world, collectively presented with an unprecedented opportunity, or even a grave common danger. To many, it seemed absurd for the contending nation states to continue their deadly quarrels when faced with a nonhuman civilization of vastly greater capabilities. There was a whiff of hope in the air. ~ Carl Sagan

Let's find and remedy all our weaknesses before our enemies get a chance to say a word. That is what Charles Darwin did ... When Darwin completed the manuscript of his immortal book "The Origin Of Species" he realized that the publication of his revolutionary concept of creation would rock the intellectual and religious worlds. So he became his own critic and spent another 15 years checking his data, challenging his reasoning, and criticizing his conclusions. ~ Dale Carnegie

This is the moment when we have to decide: does a world exist outside ourselves and is that world worth fighting for? Another 200 species went extinct today. They were my kin. They were yours, too. If we know them as such, why aren't we fighting to save them with everything we've got? ~ Lierre Keith

With none of Vader's backstory available at the time, and having just invented the Noghri species for this story, I came up with the idea that Vader might have designed his mask to look like a stylized version of a Noghri face, the better to facilitate his command of the death commando squads. ~ Timothy Zahn

I had nixed the idea of having children when I was myself a child, having learned in the 1960s that human overpopulation was literally crowding other species off the planet. Why create another mouth to gnaw at the overburdened earth? ~ Sy Montgomery

Distinction between species and specimen is very much like the distinction between images and actual pictures, or, you know, objects that have a definite material identity. The classifications, the categories, the stereotypes, and the images are on one side, and the material pictures, statues, texts, and so forth are on the other. ~ W. J. T. Mitchell

It will be possible, through the detailed determination of amino-acid sequences of hemoglobin molecules and of other molecules too, to obtain much information about the course of the evolutionary process, and to illuminate the question of the origin of species. ~ Linus Pauling

The origin of modern humanity was a stroke of luck - good for our species for a while, bad for most of the rest of life forever. All ~ Edward O. Wilson

If you based your knowledge of the human species exclusively on adverts, you'd think that the normal condition of humanity was to be a good-looking single person between 20 and 35, with excellent muscle-definition and/or an excellent figure, and a large disposable income. ~ Francis Spufford

Like all animals, human beings have always taken what they want from nature. But we are the rogue species. We are unique in our ability to use resources on a scale and at a speed that our fellow species can't. ~ Edward Burtynsky

Intelligence is the ability of a species to live in harmony with its environment. ~ Paul Watson

There's a voice that says: "So what?"
It's not my voice, it's probably not yours, but it makes itself heard in the arenas of public opinion, querulous and smug and fortified by just a little knowledge, which as always is a dangerous thing. "So what if a bunch of species go extinct?" It says. "Extinction is a natural process. Darwin himself said so, didn't he? Extinction is the complement of evolution, making room for new species to evolve. There have always been extinctions. So why worry about these extinctions currently being caused by humanity?" And there has always been a pilot light burning in your furnace. So why worry when your house is on fire? ~ David Quammen

Two classics stuck with them. Ender's Game delighted them all; here were soldiers who were just like them, except smaller. The main character was even bred to fight alien species like they were. The next day the members of the 8th greeted each other with the salutation ::Ho, Ender,:: until Brahe told them to knock it off and pay attention. ~ John Scalzi

Look, the Latin name for this fish is Carcharodon carcharias, okay? The closest ancestor we can find for it is something called Carcharodon megalodon, a fish that existed maybe thirty or forty thousand years ago. We have fossil teeth from megalodon. They're six inches long. That would put the fish at between eighty and a hundred feet. And the teeth are exactly like the teeth you see in great whites today. What I'm getting at is, suppose the two fish are really one species. What's to say megalodon is really extinct? Why should it be? Not lack of food. If there's enough down there to support whales, there's enough to support sharks that big. Just because we've never seen a hundred-foot white doesn't mean they couldn't exist. They'd have no reason to come to the surface. All their food would be way down in the deep. A dead one wouldn't float to shore, because they don't have flotation bladders. Can you imagine what a hundred-foot white would look like? Can you imagine what it could do, what kind of power it would have?It would be like a locomotive with a mouth full of butcher knives. ~ Peter Benchley

If there was ever a species that deserved purging from the surface of the planet, it is humanity. We are, or should be, a temporary infestation or infection, a smart virus awaiting its divine antidote. ~ Mal Peet

I dream of a state of affairs in which every man would know that he lives and dies for the preservation of the species. ~ Adolf Hitler

The farther you progress toward a vision of our species without limiting conditions on your consciousness, the farther you drift away from what makes you a person among persons in the human community. ~ Thomas Ligotti

The shades of difference between other people and me serve to make variety and prevent monotony, but that is all; broadly speaking, we are all alike; and so by studying myself carefully and comparing myself with other people, and noting the divergences, I have been enabled to acquire a knowledge of the human race which I perceive is more accurate and more comprehensive than that which has been acquired and revealed by any other member of our species. As a result, my private and concealed opinion of myself is not of a complimentary sort. It follows that my estimate of the human race is the duplicate of my estimate of myself. ~ Mark Twain

It has adopted the geometry most advantageous to the species or, in other words, the most convenient. ~ Henri Poincare

Something bad happened on both Mars with its dried-up watercourses and Venus with its runaway greenhouse effect. Could something bad happen on Earth too? Our species currently turns row upon row of environmental knobs, without much regard to long-term consequences. ~ Neil DeGrasse Tyson

Consider the species known as man. We lie, we cheat, we want what others have and take it; we make war upon each other and the earth; we harvest lives in multitudes.
