Human Biology 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

My own experience of over 60 years in biomedical research amply demonstrated that without the use of animals and of human beings, it would have been impossible to acquire the important knowledge needed to prevent much suffering and premature death not only among humans but also among [other] animals. — Albert Sabin

I'm convinced, though I'm no expert in biology, if you cut a dog's brain open it would just be a perfect little human brain, with none of the bad parts. — J. David Osborne

Novel technologies and ideas that impinge on human biology and their perceived impact on human values have renewed strains in the relationship between science and society. — Paul Berg

When physics, chemistry, biology, medicine, contribute to the detection of concrete human woes and to the development of plans for remedying them and relieving the human estate, they become moral; they become part of the apparatus of moral inquiry or science? When the consciousness of science is fully impregnated with the consciousness of human value, the greatest dualism which now weighs humanity down, the split between the material, the mechanical and the scientific and the moral and ideal will be destroyed. — John Dewey

Biomasses are a biological reality that cannot be denied as existing, but even though they exist physically, yet they have not attained the height of Homo sapiens. Humans could be termed as biomasses when they don't fully put into use their human qualifications. Men and women that don't bother to think. Men and women that don't bother to notice things that are out of order. People who are indifferent about the happenings around them. Men and women that don't respond with solution to the challenges of the era. All of these people are united by one common name BIOMASSES. — Sunday Adelaja

The biology of mind bridges the sciences - concerned with the natural world - and the humanities - concerned with the meaning of human experience. — Eric Kandel

The advances of science and technology will bring us to the greatest moral dilemma since God stayed the hand of Abraham: how much to retrofit the human genotype. Shall it be a lot, a little bit, or none at all? The choice will be forced on us because our species has begun to cross what is the most important yet still least examined threshold in the technoscientific era. We are about to abandon natural selection, the process that created us, in order to direct our own evolution by volitional selection - the process of redesigning our biology and human nature as we wish them to be. — Edward O. Wilson

More and more clearly every day, out of biology, anthropology, sociology, history, economic analysis, psychological insight, plain human decency and common sense, the necessary mandate of survival that we shall love all our neighbors as we do ourselves, is being confirmed and reaffirmed. — Ordway Tead

[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

Scientists who study human motivation have lately learned that after basic survival needs have been met, the combination of autonomy (the desire to direct your own life), mastery (the desire to learn, explore, and be creative), and purpose (the desire to matter, to contribute to the world) are our most powerful intrinsic drivers - the three things that motivate us most. All three are deeply woven through the fabric of flow. Thus toying with flow involves tinkering with primal biology: addictive neurochemistry, potent psychology, and hardwired evolutionary behaviors. — Steven Kotler

The price of these failures has been a loss of moral consensus, a greater sense of helplessness about the human condition ... The intellectual solution to the first dilemma can be achieved by a deeper and more courageous examination of human nature that combines the findings of biology with those of the social sciences. — E. O. Wilson

Quite recently the human descent theory has been stigmatized as the 'gorilla theory of human ancestry.' All this despite the fact that Darwin himself, in the days when not a single bit of evidence regarding the fossil ancestors of man was recognized, distinctly stated that none of the known anthropoid apes, much less any of the known monkeys, should be considered in any way as ancestral to the human stock. — Henry Fairfield Osborn

Roadblock #5: It's Unpredictable
By and large, human beings don't like surprises. I know that I don't. Okay, maybe I like that rare piece of unexpected good news or a letter from a friend or a thoughtful thank-you. But I'm willing to bet that people in funny hats jumping out of dark closets are responsible for more heart attacks than expressions of unbridled delight. When the doorbell rings late at night, I'm under no illusion that it's the Publisher's Clearing House Prize Patrol!
This, most likely, goes back to our caveman past when a big, exciting surprise was apt to be something like an 800-pound,snarling, saber-toothed tiger about to rip the head from our shoulders. Surprises were usually bad news. (Think about this the next time you're crouching in the dark in somebody's front hall closet with their raincoats and umbrellas.) — Paul Powers

As long as museums and universities send out expeditions to bring to light new forms of living and extinct animals and new data illustrating the interrelations of organisms and their environments, as long as anatomists desire a broad comparative basis human for anatomy, as long as even a few students feel a strong curiosity to learn about the course of evolution and relationships of animals, the old problems of taxonomy, phylogeny and evolution will gradually reassert themselves even in competition with brilliant and highly fruitful laboratory studies in cytology, genetics and physiological chemistry. — William King Gregory

As more and more norms disappear from social praxis, literature faces ever-growing difficulties. Its predicament is beginning to resemble that of a child who has discovered that his incredibly understanding parents will let him break with impunity all his toys, indeed everything in the house. The artist cannot create specific prohibitions for himself in order to attack them later in his work; the prohibitions must be real, and hence independent of the writer's choices. And since the relativization of cultural norms has not so far been able to disturb the given characteristics of human biology, that is where writers today seek the still perceptible points of resistance
which is why literature is preoccupied with the theme of sex. — Stanislaw Lem

For nine months I grew a human being inside my belly and then I pushed it out my vagina and now I'm feeding it with my boob. Biology is so fucking weird. — Heather B. Armstrong

I am perhaps more proud of having helped to redeem the character of the cave-man than of any other single achievement of mine in the field of anthropology. — Henry Fairfield Osborn

Fear or anxiety is a normal part of living. It's the body's way of telling us something isn't right. It keeps us from harm's way and prepares us to act quickly in the face of danger. — Abhijit Naskar

I don't believe, for instance, that evolutionary biology or any scientific endeavor has much to say about love. I'm sure a lot can be learned about the importance of hormones and their effects on our feelings. But do the bleak implications of evolution have any impact on the love I feel for my family? Do they make me more likely to break the law of flaunt society's expectations of me? No. I simply does not follow that human relationships are meaningless just because we live in a godless universe subject to the natural laws of biology. — Greg Graffin

Advocacy of leaf protein as a human food is based on the undisputed fact that forage crops (such as lucerne) give a greater yield of protein than other types of crops. Even with conventional food crops there is more protein in the leafy parts than in the seeds or tubs that are usually harvested. — Norman Pirie

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

[ ... ] we have in our treatise a series of fifty-seven examinations, almost exclusively of injuries of the human body forming a group of observations furnishing us with the earliest known nucleus of fact regarding the anatomy, physiology and pathology of the human body. Crude and elementary as they are, the method by which they were collected was scientific, and these observations, together with the diagnoses and the explanatory commentary in the ancient glosses, form the oldest body of science now extant. — James Henry Breasted

Biology Under the Influence is a collection of our essays built around the general theme of the dual nature of science. On the one hand, science is the generic development of human knowledge over the millennia, but on the other it is the increasingly commodified specific product of a capitalist knowledge industry. — Richard C. Lewontin

Change biology, and you could change society--but could you change society on its own? Were we as a species simply condemned to permanent misery, all because of how we have evolved?

This was the conundrum that the Oankali books had posed to her, and the Parables had been intended (but failed) to solve: How do you create a more sustainable, more benign, more livable society when you're stuck working with human beings? — Gerry Canavan

in human males, testosterone appears to promote behavior intended to dominate other people. This behavior can be expressed aggressively, even violently, as well as nonaggressively. Testosterone levels, even a single baseline measurement, correlate well with dominance behavior, that is, testosterone not only affects dominance behavior but also responds to it. — Randy J. Nelson

nine of every ten cells in our bodies belong not to us, but to these microbial species (most of them residents of our gut), and that 99 percent of the DNA we're carrying around belongs to those microbes. Some scientists, trained in evolutionary biology, began looking at the human individual in a humbling new light: as a kind of superorganism, a community of several hundred coevolved and interdependent species. — Michael Pollan

It is also only in humans that aggression may be used to commit crimes, to enslave others or compel acquiescence to religious or ideological doctrine, or to pursue wars of national interest. At the individual level, men are universally more aggressive than women, and rates of aggressive confrontation are greatest among those who are young, poor, or unmarried. Cultural factors moderate human aggression as well, with men's heightened sensitivity to signs of disrespect, challenge, or threat spawning a high frequency of confrontational violence in so-called "cultures of honor". — Randy J. Nelson

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

Things to know from books to read — Kip Koehler

Human beings appear to be sufficiently selfish and calculating to be capable of indefinitely greater harmony and social homeostasis. This statement is not self-contradictory. True selfishness, if obedient to the other constraints of mammalian biology, is the key to a more nearly perfect social contract. - pg. 157 — Edward O. Wilson

Biology alone cannot provide an answer to the question that concerns us: why is woman the Other? The question is how, in her, nature has been taken on in the course of history; the question is what humanity has made of the human female. — Simone De Beauvoir

In consequence of Darwin's reformed Theory of Descent, we are now in a position to establish scientifically the groundwork of a non-miraculous history of the development of the human race ... If any person feels the necessity of conceiving the coming into existence of this matter as the work of a supernatural creative power, of the creative force of something outside of matter, we have nothing to say against it. But we must remark, that thereby not even the smallest advantage is gained for a scientific knowledge of nature. Such a conception of an immaterial force, which as the first creates matter, is an article of faith which has nothing whatever to do with human science. — Ernst Haeckel

[On scientist Carl Friedrich Gauss]
[Carl Friedrich] Gauss told his friend Rudolf Wagner, a professor of biology at Gottingen University, that he did not believe in the Bible but that he had meditated a great deal on the future of the human soul and speculated on the possibility of the soul being reincarnated on another planet. Evidently, Gauss was a Deist with a good deal of skepticism concerning religion. — Gerhard Falk

Physics investigates the essential nature of the world, and biology describes a local bump. Psychology, human psychology, describes a bump on the bump. — Willard Van Orman Quine

Bodies are not only biological phenomena but also complex social creations onto which meanings have been variously composed and imposed according to time and space. — Katrina Karkazis

A man described by authorities as one evolutionary step above a banana slug has recently admitted to having been locked in the Sacajawea Junior High biology lab over a long weekend nearly sixteen years ago when he fell asleep and was mistaken as a cadaver. Though the man is incapable of human speech, he was able, over a period of weeks, to chisel out his story in hieroglyphics on the bathroom wall of the insane asylum where he now resides. He claims that toward the end of the second day of his accidental captivity, he got downright lonely and sought companionship at his own intellectual level. He found that companionship in a petri dish. — Chris Crutcher

That enormously complex biological interactions are so flawlessly coordinated as to result in such obvious manifestations as human thought or the electrical activity that dries the heartbeat is as exciting to me
actually more exciting
than such phenomena were when I was a small boy and thought them divinely (in the supernatural sense) driven. — Sherwin B. Nuland

It is my belief that the basic knowledge that we're providing to the world will have a profound impact on the human condition and the treatments for disease and our view of our place on the biological continuum. — J. Craig Venter

Something happens to you when you begin to think about this planet as a single living organism. And when you begin to live in that awareness, nothing is ever again quite the same. Nothing can be the same after that. Nations began to look like people to me, like familiar friends. The distinctions between religion, biology, and politics began to blur. I began to wonder why I had always assumed that human thought was the only kind of thought - as if nature would be content with a single species of flower, or just one kind of tree. — Ken Carey

The source of man is in man,and when a man dies,millions of men die in him. — Michael Bassey Johnson

Biology doesn't know in advance what the end product will be; there's no Stuffit Compressor to convert a human being into a genome. But the genome itself is very much akin to a compression scheme, a terrifically efficient description of how to build something of great complexity-perhaps more efficient than anything yet developed in the labs of computer scientists (never mind the complexities of the brain, there are trillions of cells in the rest of the body, and they are all supervised by the same 30,000-gene genome). And although there is no counterpart in nature to a program that compresses a picture into a compact description, there is a natural counterpart to the program that decompresses the compressed encoding, and that's the cell. Genome in, organism out. Through the logic of gene expression, cells are self-regulating factories that translate genomes into biological structure. — Gary F. Marcus

If a single cell, under appropriate conditions, becomes a man in the space of a few years, there can surely be no difficulty in understanding how, under appropriate conditions, a cell may, in the course of untold millions of years, give origin to the human race. — Herbert Spencer

Still, if history and science have taught us anything, it is that passion and desire are not the same as truth. The human mind evolved to believe in the gods. It did not evolve to believe in biology. Acceptance of the supernatural conveyed a great advantage throughout prehistory when the brain was evolving. Thus it is in sharp contrast to biology, which was developed as a product of the modern age and is not underwritten by genetic algorithms. The uncomfortable truth is that the two beliefs are not factually compatible. As a result those who hunger for both intellectual and religious truth will never acquire both in full measure. — Edward O. Wilson

Soul" is a barrier against reduction, against human life reduced to biology and genitals, culture and utility, race and ethnicity. It signals an interiority that permeates all exteriority, an invisibility that everywhere inhabits visibility. "Soul" carries with it resonances of God-created, God-sustained, and God-blessed. It is our most comprehensive term for designating the core being of men and women. — Eugene H. Peterson

I know that there are many essential biological differences between the sexes, of course. But not so many 'culturally-mandated' differences. In First World countries we've evolved beyond mere biology -it isn't the fate of the human female to be pregnant continously until she wears out and dies. — Joyce Carol Oates

One of my friends compared me to Bruce Banner, due to my work with radiation and human health. So I looked up Bruce Banner and this is what I found: Banner, a physicist, is sarcastic and seemingly very self-assured when he first appears in Incredible Hulk #1, but is also emotionally withdrawn in most fashions ... Banner is considered one of the greatest scientific minds on Earth, possessing "a mind so brilliant it cannot be measured on any known intelligence test." He holds expertise in biology, chemistry, engineering, physiology, and nuclear physics. — Steven Magee

We can construct, deconstruct and reconstruct our sexuality any way we want: it is our privilege as thinking creatures. However, human sexuality has a specific nature, regardless of what we believe or say about it. We are more likely to be satisfied with the outcome, if we work with our biology rather than against it. We will be happier if we face reality on its own terms. — Jennifer Morse

One way of emphasizing the singularity of the recent past is [..] to observe that the total number of humans ever to have lived is estimated at around (a bit less than) 100 billion. One of Walt Whitman's poems has a memorable image - thinking of all past people lined up in orderly columns behind those living - 'row upon row rise the phantoms behind us'. Actually, looking over our shoulder, we would see only around 15 rows. — Robert M. May

Throughout history we humans have struggled to find meaning in the awesome contradiction of our human condition. Neither philosophy, nor psychology nor biology has, until now, been able to provide the truthful explanation. — Jeremy Griffith

Because the great beauty of embryo development, the bit that human beings find so hard to grasp, is that it is a totally decentralised process ... no cell need wait for instructions from authority; every cell can act on its own information and the signals it receives from its neighbours. We do not organise societies that way ... Perhaps we should try. — Matt Ridley

Dent recognized it; the intermezzo before the last movement of De Bruik's Human Biology. The finale of the symphony was a standard concert opener in the outer worlds. Soon the crackling of superamplified muscle contractions and the rush of adrenaline into the bloodstream announced the shift to the finale, and the crowd cheered wildly; Dent could feel his blood surging through him - — Kim Stanley Robinson

Human experience is not nest and orderly, ready to be coded into predetermined categories. Real life is messy — Jennifer Gold

it is high time we stop using the term "theory" while mentioning Evolution. The term "theory" somehow makes some people think of Evolution as an unproven "hypothesis". Theory of Evolution is an incontrovertible fact of science. It is not a fictitious story like Creationism. It's a hard reality. It is the bed-rock of Biology. Defying evolution means defying one's own existence as a human being. — Abhijit Naskar

Although in principle we know the equations that govern the whole of biology, we have not been able to reduce the study of human behavior to a branch of applied mathematics. — Stephen Hawking

As Gove knows ... 'Scientific education for the masses will do little good, and probably a lot of harm, if it simply boils down to more physics, more chemistry, more biology, etc to the detriment of literature and history. Its probable effect on the average human being would be to narrow the range of his thoughts and make him more than ever contemptuous of such knowledge as he did not possess.' — George Orwell

It seems a miracle that young children easily learn the language of any environment into which they were born. The generative approach to grammar, pioneered by Chomsky, argues that this is only explicable if certain deep, universal features of this competence are innate characteristics of the human brain. Biologically speaking, this hypothesis of an inheritable capability to learn any language means that it must somehow be encoded in the DNA of our chromosomes. Should this hypothesis one day be verified, then lingusitics would become a branch of biology. — Niels Kaj Jerne

To be motherly is a totally different phenomenon. It is something absolutely human; it transcends animality. It has nothing to do with biology. It is love, pure love, unconditional love. When a mother loves unconditionally - and only a mother can love unconditionally - the child learns the joy of unconditional love. The child becomes capable of loving unconditionally. And to be able to love unconditionally is to be religious. And it is the easiest thing for a woman to do. It is easy for her because naturally she is ready for it. — Rajneesh

What politicians do not understand is that [Ian] Wilmut discovered not so much a technical trick as a new law of nature. We now know that an adult mammalian cell can fire up all the dormant genetic instructions that shut down as it divides and specializes and ages, and thus can become a source of new life. You can outlaw technique; you cannot repeal biology.
Writing after Wilmut's successful cloning of the sheep, Dolly, that research on the cloning of human beings cannot be suppressed. — Charles Krauthammer

Without the harmonious electrochemical activity of all the brain structure, the very thing which we call "mind", would suddenly disappear from the face of earth. — Abhijit Naskar

The Biology of Hope and the Healing Power of the Human Spirit, — Brian L. Weiss

We treat human biology as our center point. Everyone already has a head-mounted display. It's your head! — Rony Abovitz

Religion is an attempt to get control over the sensory world, in which we are placed, by means of the wish-world, which we have developed inside us as a result of biological and psychological necessities. But it cannot achieve its end. Its doctrines carry with them the stamp of the times in which they originated, the ignorant childhood days of the human race. Its consolations deserve no trust. Experience teaches us that the world is not a nursery. The ethical commands, to which religion seeks to lend its weight, require some other foundations instead, for human society cannot do without them, and it is dangerous to link up obedience to them with religious belief. If one attempts to assign to religion its place in man's evolution, it seems not so much to be a lasting acquisition, as a parallel to the neurosis which the civilized individual must pass through on his way from childhood to maturity. — Sigmund Freud

Growing up human is uniquely a matter of social relations rather than biology. What we learn from connections within the family takes the place of instincts that program the behavior of animals; which raises the question, how good are these connections? — Elizabeth Janeway

So teach Chizalum that biology is an interesting and fascinating subject, but she should never accept it as justification for any social norm. Because social norms are created by human beings, and there is no social norm that cannot be changed. — Chimamanda Ngozi Adichie

The past three decades have witnessed unprecedented growth in what researchers now term ultimate human performance. This is not the same as optimal human performance, and the difference is in the consequences. Optimal performance is about being your best; ultimate performance is about being your best when any mistake could kill. Both common sense and evolutionary biology tell us that progress under these "ultimate" conditions should be a laggard's game, but that's not exactly what the data suggests. — Steven Kotler

We live in a society where we're not taught how to deal with our weaknesses and frailties as human beings. We're not taught how to speak to our difficulties and challenges. We're taught the Pythagorean theorem and chemistry and biology and history. We're not taught anger management. We're not taught dissolution of fear and how to process shame and guilt. I've never in my life ever used the Pythagorean theorem! — Iyanla Vanzant

It is precisely the envelopment of sex (and all other natural functions) with an aura of deeper meaning that makes man human and distinguishes him from the rest of animate nature. To remove that meaning, to reduce sex to biology, as all the sexual revolutionaries did in practice, is to return man to a level of primitive behavior of which we have no record in human history. All animals have sex, but only man makes love. — Theodore Dalrymple

Scholarship that is indifferent to human suffering is immoral. — Richard Levins

If we wish to know about a man, we ask 'what is his story
his real, inmost story?'
for each of us is a biography, a story. Each of us is a singular narrative, which is constructed, continually, unconsciously, by, through, and in us
through our perceptions, our feelings, our thoughts, our actions; and, not least, our discourse, our spoken narrations. Biologically, physiologically, we are not so different from each other; historically, as narratives
we are each of us unique. — Oliver Sacks

What motivates Olympic athletes to train for years for one event - in some cases, for just seconds of actual competition? It's the same thing that kept my friend Pete nosing around old bookstores for years. It's the same thing that makes a person venture out of a comfortable job to start a new business. We see it in the artist who spends day after day in a studio chipping away at a block of stone. Look closely and you'll find it in the shopper who passes up the good deal in search of the best deal. It's one of the things that makes us most human. We consciously pursue what we value. It's not simply a matter of being driven by biology or genetics or environmental conditioning to satisfy instinctive cravings. Rather, we perceive something, prize it at a certain value, then pursue it according to that assigned value because we were created that way. This ability to perceive, prize, and pursue is part of our essential humanness, and it's the essence of ambition. — Dave Harvey

In the ensuing chapters, we will look in some detail at particular manifestations of the modern scientific ideology and the false paths down which it has led us. We will consider how biological determinism has been used to explain and justify inequalities within and between societies and to claim that those inequalities can never be changed. We will see how a theory of human nature has been developed using Darwin's theory of evolution by natural selection to claim that social organization is also unchangeable because it is natural. We will see how problems of health and disease have been located within the individual so that the individual becomes a problem for society to cope with rather than society becoming a problem for the individual. And we will see how simple economic relationships masquerading as facts of nature can drive the entire direction of biological research and technology. — Richard C. Lewontin

We are surrounded by the absurd excess of the universe. By meaningless bulk, vastness without size, power without consequence. The stubborn iteration that is present without being felt. Nothing the spirit can marry. Merely phenomenon and its physics. An endless, endless of going on. No habitat where the brain can recognize itself. No pertinence for the heart. Helpless duplication. — Jack Gilbert

In a high tech world the cure for the tragic shortcomings and perilous fallacies of human intuition is education, but education in economics, evolutionary biology, probability and statistics - unfortunately most High School and College curricula have barely changed since Medieval times! — Steven Pinker

It is a part of our nature to survive. Faith is an instinctive response to aspects of existence that we cannot explain by any other means, be it the moral void we perceive in the universe, the certainty of death, the mystery of the origin of things, the meaning of our lives, or the absence of meaning. These are basic and extremely simple aspects of existence, but our limitations prevent us from responding in an unequivocal way and for that reason we generate an emotional response, as a defense mechanism. It's pure biology. — Carlos Ruiz Zafon

Evidently neither cats nor dogs, nor other animals that listen to human music, were constituted for the appreciation of it, for it is not of the slightest use to them in the struggle for existence. Moreover, they and their organs of hearing were much older than man and his music. Their power of appreciating music is therefore an uncontemplated side-faculty of a hearing apparatus which has become on other grounds what we find it to be. So it is, I believe, with man. He has not acquired his musical hearing as such, but has received a highly developed organ of hearing by a process of selection, because it was necessary to him in the selective process ; and this organ of hearing happens also to be adapted to listening to music. — August Weismann

Considering that we live in an era of evolutionary everything
evolutionary biology, evolutionary medicine, evolutionary ecology, evolutionary psychology, evolutionary economics, evolutionary computing
it was surprising how rarely people thought in evolutionary terms. It was a human blind spot. We look at the world around us as a snapshot when it was really a movie, constantly changing. — Michael Crichton

Movements for animal rights are not irrational denials of human uniqueness; they are a clear-sighted recognition of connection across the discredited breach of nature and culture. Biology and evolutionary theory over the last two centuries have simultaneously produced modern organisms as objects of knowledge and reduced the line between humans and animals to a faint trace re-etched in ideological struggle or professional disputes between life and social science. Within this framework, teaching modern Christian creationism should be fought as a form of child abuse. — Donna J. Haraway

I can see no practical application of molecular biology to human affairs ... DNA is a tangled mass of linear molecules in which the informational content is quite inaccessible. — Frank Macfarlane Burnet

Random mutations much more easily debilitate genes than improve them, and that this is true even of the helpful mutations. Let me emphasize, our experience with malaria's effects on humans (arguably our most highly studied genetic system) shows that most helpful mutations degrade genes. What's more, as a group the mutations are incoherent, meaning that they are not adding up to some new system. They are just small changes - mostly degradative - in pre-existing, unrelated genes. The take-home lesson is that this is certainly not the kind of process we would expect to build the astonishingly elegant machinery of the cell. If random mutation plus selective pressure substantially trashes the human genome, why should we think that it would be a constructive force in the long term? There is no reason to think so. — Michael J. Behe

I thought the fart was a human thing. It's something to do with like, arse cheeks, or whatever. — Karl Pilkington

Throughout the lifetime, the entire neurobiology of a human being goes through relentless perplexing transformations. These sexually dimorphic neurobiological changes create a person's personality. These unique makeovers of the male and female biology hold the key to a sustainable romantic relationship. — Abhijit Naskar

A man woke up at midnight and wanted to smoke. Therefore he looked for some fire, for which he went to a neighbor's house and knocked at the door. The neighbor opened the door and asked him what he wanted. The man said, I wish to smoke. Can you give me a little fire? The neighbor replied, O.M.G.! What the heck is wrong with you? You have taken so much trouble to come and wake us up at the middle of the night, while in your own hand you have a lantern! The God that human beings so keenly seek, lives within the human biology, yet they wander hitherto searching for it. — Abhijit Naskar

Biology will relate every human gene to the genes of other animals and bacteria, to this great chain of being. — Walter Gilbert

Even though it is common knowledge in our field of Neuroscience, I take immense pleasure every time I realize that our perception of the whole universe emerges from the activity of the little specks of jelly inside our skull. — Abhijit Naskar

Some believe what separates men from animals is our ability to reason. Others say it's language or romantic love, or opposable thumbs. Living here in this lost world, I've come to believe it is more than our biology. What truly makes us human is our unending search, our abiding desire for immortality. — Arthur Conan Doyle

A garden is the place millions of people go to touch the earth, to smell flowers - to use some of that fabled human brain power in the cause of better participating with natural processes in the place they call home. It serves as an art project, an organic produce market, a spiritual practice, a pharmacy. It offers ongoing lessons in ecology, biology, chemistry, geology, meteorology. Gardening imparts an organic perspective on the passage of time. It bestows on its practitioners a genuine sense of admiration for the plants, the soil, the sun, the water. — Jim Nollman

Maybe everyone else thinks your aversion to food is cute- but not me. I've watched you watch Jill. Here's some tough love: you will never, ever have her body. Ever. It's impossible. She's Moroi. You're human. That's biology. You have a great one, one that most humans would kill for- and you'd look even better if you put on a little weight. Five pounds would be a good start. Hide the ribs. Get a bigger bra size — Richelle Mead

The separation of psychology from the premises of biology is purely artificial, because the human psyche lives in indissoluble union with the body. — Carl Jung

Cockroach: What is war?
Man: How we lost the human race. — Anthony Marais

The purpose of Neurotheology shall be to ease human sufferings with a deeper understanding of the neurobiological substrates of spirituality and divinity. — Abhijit Naskar

Biology includes the study of the human death which began when you took your first breath — Stanley Victor Paskavich

Evolution on the large scale unfolds, like much of human history, as a succession of dynasties. — Edmund Beecher Wilson

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

The scientific method," Thomas Henry Huxley once wrote, "is nothing but the normal working of the human mind." That is to say, when the mind is working; that is to say further, when it is engaged in corrrecting its mistakes.
Taking this point of view, we may conclude that science is not physics, biology, or chemistry
is not even a "subject"
but a moral imperative drawn from a larger narrative whose purpose is to give perspective, balance, and humility to learning. — Neil Postman

Humanity shares a common ancestry with all living things on Earth. We often share especially close intimacies with the microbial world. In fact, only a small percentage of the cells in the human body are human at all. Yet, the common biology and biochemistry that unites us also makes us susceptible to contracting and transmitting infectious disease. — Brenda Wilmoth Lerner

Once I dated a woman I only liked 43%.
So I only listened to 43% of what she said.
Only told the truth 43% of the time.
And only kissed with 43% of my lips.
Some say you can't quantify desire,
attaching a number to passion isn't right,
that the human heart doesn't work like that.
But for me it does-I walk down the street
and numbers appear on the foreheads
of the people I look at. In bars, it's worse.
With each drink, the numbers go up
until every woman in the joint has a blurry
eighty something above her eyebrows,
and the next day I can only remember 17%
of what actually happened. That's the problem
with booze-it screws with your math. — Jeffrey McDaniel

Recent studies have considered the detection of a spaceship visiting our parish of the galaxy. In my opinion that last thought should bring a blush to every human cheek ... Fecklessness might be the main theme of the aliens' report on the new-found source of radio pollution ... that emanates from beings who have mastered a lot of physics, chemistry and biology and yet let their children starve-while all around their planet the energy of their mother star runs to waste in a desert of space. — Nigel Calder

I want to know where joy lives. I'd interview scientists, religious leaders and heads of state. I'd want to find out exactly what makes people happy. I'd want to look into the biology, the chemistry of the human brain. — Goldie Hawn

Very often conditions are recorded as observable "under thy fingers" [ ... ] Among such observations it is important to notice that the pulsations of the human heart are observed. — James Henry Breasted
