Biology Quotes

Another explanation for the failure of logic and observation alone to advance medicine is that unlike, say, physics, which uses a form of logic - mathematics - as its natural language, biology does not lend itself to logic. Leo Szilard, a prominent physicist, made this point when he complained that after switching from physics to biology he never had a peaceful bath again. As a physicist he would soak in the warmth of a bathtub and contemplate a problem, turn it in his mind, reason his way through it. But once he became a biologist, he constantly had to climb out of the bathtub to look up a fact.

Before the girl and the boy tie the knot, they feel like falling in love. And most of them do. Cupid works. Biology demands. And, sociology warrants.

From a biology point of view, the purpose of humanity is to ensure his survival by expanding his domain into the stars.

I personally cannot discern a shred of evidence for ‘[intelligent] design.’ If 97% of all creatures have gone extinct, some plan isn't working very well!

In AP Bio, I learned that the cells in our body are replaced every seven years, which means that one day, I'll have a body full of cells that were never sick. But it also means that parts of me that knew and loved Sadie will disappear. I'll still remember loving her, but it'll be a different me who loved her. And maybe this is how we move on. We grow new cells to replace the grieving ones, diluting our pain until it loses potency.The percentage of my skin that touched hers will lessen until one day my lips won't be the same lips that kissed hers, and all I'll have are the memories. Memories of cottages in the woods, arranged in a half-moon. Of the tall metal tray return in the dining hall. Of the study tables in the library. The rock where we kissed. The sunken boat in Latham's lake, Sadie, snapping a photograph, laughing the lunch line, lying next to me at the movie night in her green dress, her voice on the phone, her apple-flavored lips on mine. And it's so unfair. All of it.

Evolutionarily speaking, love is all about procreation.

The typical imperative from biology is not "Thou shalt... ," but "If ... then ... else.

Whenever explaining an event, we must choose from three competing modes of explanation. These are regularity, chance, and design... To attribute an event to design is to say that it cannot reasonably be referred to either regularity or chance.

Seen in the light of evolution, biology is, perhaps, intellectually the most satisfying and inspiring science. Without that light it becomes a pile of sundry facts -- some of them interesting or curious but making no meaningful picture as a whole.

Science, as long as it limits itself to the descriptive study of the laws of nature, has no moral or ethical quality and this applies to the physical as well as the biological sciences.

The very comprehensibility of the world points to an intelligence behind the world. Indeed, science would be impossible if our intelligence were not adapted to the intelligibility of the world. The match between our intelligence and the intelligibility of the world is no accident. Nor can it properly be attributed to natural selection, which places a premium on survival and reproduction and has no stake in truth or conscious thought. Indeed, meat-puppet robots are just fine as the output of a Darwinian evolutionary process.

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.

(Evolution) general condition to which all theories, all hypotheses, all systems must bow and which they must satisfy henceforward if they are to be thinkable and true. Evolution is a light which illuminates all facts, a curve that all lines must follow.

There are species that retain their characteristics even in conditions that are relatively different from their natural ones; other species in similar circumstances instead become extinct; otherwise what takes place is racial mixing with other elements in which no assimilation or real evolution occurs. The result of this interbreeding closely resembles Mendel’s laws concerning heredity: once it disappears in the phenotype, the primitive element survives in the form of a separated, latent heredity that is capable of cropping up in sporadic apparitions, even though it is always endowed with a character of heterogeneity in regard to the superior type.

Stop talking about “rape” and start talking about “sex”, and within a few decades India will attain the true mindset to prevent sexual assaults.

This new consensus seemed so compelling that Ernst Mayr, the dean of modern Darwinians, opened the ashcan of history for a deposit of Geoffrey's ideas about anatomical unity.

No Lord Almighty created the humans out of personal will. Creationism is simply a myth created by the weak and ignorant humans out of a psychological need to have a sense of eternal security.

I studied calculus for the first time, which to me was an amazingly empowering experience which I could really see how you could understand all sorts of things, and I decided that chemistry and biology just had too much memory for me to be interested. Physics was very easy.

Considering the way the prebiotic soup is referred to in so many discussions of the origin of life as an already established reality, it comes as something of a shock to realize that there is absolutely no positive evidence for its existence.

Scientists rightly resist invoking the supernatural in scientific explanations for fear of committing a god-of-the-gaps fallacy (the fallacy of using God as a stop-gap for ignorance). Yet without some restriction on the use of chance, scientists are in danger of committing a logically equivalent fallacy-one we may call the “chance-of-the-gaps fallacy.” Chance, like God, can become a stop-gap for ignorance.

The foreign policy aim of ants can be summed up as follows: restless aggression, territorial conquest, and genocidal annihilation of neighboring colonies whenever possible. If ants had nuclear weapons, they would probably end the world in a week.

This view, as a rounded whole and in all its essential elements, has very recently disappeared from science. It died a royal death with Agassiz.[It had formerly been held that there were no genetic connections among species.]

Imagine a house coming together spontaneously from all the information contained in the bricks: that is how animal bodies are made.

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.

Reply when questioned on the safety of the polio vaccine he developed:It is safe, and you can't get safer than safe.

The practice of that which is ethically best—what we call goodness or virtue—involves a course of conduct which, in all respects, is opposed to that which leads to success in the cosmic struggle for existence. In place of ruthless self-assertion it demands self-restraint; in place of thrusting aside, or treading down, all competitors, it requires that the individual shall not merely respect, but shall help his fellows... It repudiates the gladiatorial theory of existence... Laws and moral precepts are directed to the end of curbing the cosmic process.

All the more recent work on alkaptonuria has... strengthened the belief that the homogentisic acid excreted is derived from tyrosine, but why alkaptonuric individuals pass the benzene ring of their tyrosine unbroken and how and where the peculiar chemical change from tyrosine to homogentisic acid is brought about, remain unsolved problems.

I am above the forest region, amongst grand rocks & such a torrent as you see in Salvator Rosa's paintings vegetation all a scrub of rhodos. with Pines below me as thick & bad to get through as our Fuegian Fagi on the hill tops, & except the towering peaks of P. S. [perpetual snow] that, here shoot up on all hands there is little difference in the mt scenery—here however the blaze of Rhod. flowers and various colored jungle proclaims a differently constituted region in a naturalist's eye & twenty species here, to one there, always are asking me the vexed question, where do we come from?[Letter to Charles Darwin 24 Jun 1849]

I told my three sons stories about germs more than fifty years ago as fanciful bedtime tales.

Are we biology or God or something higher? I know my heart beats and I listen to it. The beat is biology, but what is the song?

At the atomic level, matter does not even exist with certainty; it only exists as a tendency to exist.

Homosexuality is neither a sin, nor an anomaly or a disease. It is an evolutionary variation.

A century ago, people laughed at the notion that we were descended from monkeys. Today, the individuals most offended by that claim are the monkeys.

The human interpretation of a disability is a primitive departmentalized view of ignorance.

All disciplines of science are built on the causality of the relationships governing related events. Yet the theory of evolution is built upon the idea of accidental changes that resulted in complex living systems. I was unable to comprehend how the notion that an infinite number of random accidents systematically happened to produce living species, and kept improving these beings, is justified.

I submit a body of facts which cannot be invalidated. My opinions may be doubted, denied, or approved, according as they conflict or agree with the opinions of each individual who may read them; but their worth will be best determined by the foundation on which they rest—the incontrovertible facts.

Inside a jihadi brain, the neuropsychological elements of aggression and rage run rampant, due to socio-political conditions. These overwhelming mental elements of young souls, when attached to the sacred texts of the Quran, by the authoritarian groups of fundamentalists, become weapons of mass destruction in the pursuit of the exclusive supremacy of one religion over the others.

...it is entirely illogical to consider biology in dichotomous terms of genes and environment—all of biology is based on the continuous interaction of both.

​I wanted to present Neuroscience to people in a way that would diminish their differences.

A lifetime can be spent in a Magellanic voyage around the trunk of a single tree.

It is not always the magnitude of the differences observed between species that must determine specific distinctions, but the constant preservation of those differences in reproduction.

The conclusion of intelligent design flows naturally from the data itself—not from sacred books or sectarian beliefs. Inferring that biochemical systems were designed by an intelligent agent is a humdrum process that requires no new principles of logic or science. It comes simply from the hard work that biochemistry has done over the past forty years, combined with consideration of the way in which we reach conclusions of design every day.

God is an energy, rather than an anthropomorphic being, and God's language is biology. Red blood cells, the principle of magnetic attraction, neurological synapse: each is a miracle, and in each is the presence and flow of God.

Man wants to see nature and evolution as separate from human activities. There is a natural world, and there is man. But man also belongs to the natural world. If he is a ferocious predator, that too is part of evolution. If cod and haddock and other species cannot survive because man kills them, something more adaptable will take their place. Nature, the ultimate pragmatist, doggedly searches for something that works. But as the cockroach demonstrates, what works best in nature does not always appeal to us.

Information and complexity go hand in hand.

[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.

In the absence of data, we will always make up stories. In fact, the need to make up a story, especially when we are hurt, is part of our most primitive survival wiring. Mean making is in our biology, and our default is often to come up with a story that makes sense, feels familiar, and offers us insight into how best to self-protect.

To grasp the reality of life as it has been revealed by molecular biology, we must magnify a cell a thousand million times until it is twenty kilometers in diameter and resembles a giant airship large enough to cover a great city like London or New York. What we would then see would be an object of unparalleled complexity and adaptive design. On the surface of the cell we would see millions of openings, like the port holes of a vast space ship, opening and closing to allow a continual stream of materials to flow in and out. If we were to enter one of these openings we would find ourselves in a world of supreme technology and bewildering complexity.

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

winning or losing an agonist encounter has a dramatic impact on future aggressive behavior. Winners are more likely to initiate attacks against unknown opponents, whereas losers are more circumspect and likely to retreat from unfamiliar conspecifics, adopting an opportunistic strategy, picking and choosing their fights. In the worst case scenario, animals socially subjugated by constant threat and attack from dominant conspecifics develop a submissive phenotype, showing little or no aggressive behavior, essentially eliminating themselves from the gene pool.

Among all the occurrences possible in the universe the a priori probability of any particular one of them verges upon zero. Yet the universe exists; particular events must take place in it, the probability of which (before the event) was infinitesimal. At the present time we have no legitimate grounds for either asserting or denying that life got off to but a single start on earth, and that, as a consequence, before it appeared its chances of occurring were next to nil. ... Destiny is written concurrently with the event, not prior to it... The universe was not pregnant with life nor the biosphere with man. Our number came up in the Monte Carlo game. Is it surprising that, like the person who has just made a million at the casino, we should feel strange and a little unreal?

Except for the rare cases of plastid inheritance, the inheritance of all known cofactors can be sufficiently accounted for by the presence of genes in the chromosomes. In a word the cytoplasm may be ignored genetically.

How can we distinguish what is biologically determined from what people merely try to justify through biological myths? A good rule of thumb is ‘Biology enables, Culture forbids.’ Biology is willing to tolerate a very wide spectrum of possibilities. It’s culture that obliges people to realize some possibilities while forbidding others. Biology enables women to have children – some cultures oblige women to realize this possibility. Biology enables men to enjoy sex with one another – some cultures forbid them to realize this possibility. Culture tends to argue that it forbids only that which is unnatural. But from a biological perspective, nothing is unnatural. Whatever is possible is by definition also natural. A truly unnatural behavior, one that goes against the laws of nature, simply cannot exist.

Natural Sciences are all about fascinating causality.

In contemporary parlance, sex is biological and gender is socially constructed.

As Karl Marx once noted: 'Hegel remarks somewhere that all great, world-historical facts and personages occur, as it were, twice. He forgot to add: the first time as tragedy, the second as farce.' William Jennings Bryan and the Scopes trial was a tragedy. The creationists and intelligent design theorists are a farce.

In real life there is no such person as the average man. There are only particular men, women and children, each with his or her inborn idiosyncrasies of mind and body, and all trying (or becoming compelled) to squeeze their biological diversities into the uniformity of some cultural mold.

Our terminal decline into old age and death stems from the fine print of the contract that we signed with our mitochondria two billion years ago.

We cannot fathom the marvelous complexity of an organic being; but on the hypothesis here advanced this complexity is much increased. Each living creature must be looked at as a microcosm--a little universe, formed of a host of self-propagating organisms, inconceivably minute and as numerous as the stars in heaven.

Love, in its purest form, is biology.
