Biology Quotes

We all know interspecies romance is weird.

~ Tim Burton

It is a curious situation that the sea, from which life first arose should now be threatened by the activities of one form of that life. But the sea, though changed in a sinister way, will continue to exist; the threat is rather to life itself.

~ Rachel Carson

If this book has a lesson, it is that we are awfully lucky to be here-and by 'we' I mean every living thing. To attain any kind of life in this universe of ours appears to be quite an achievement. As humans we are doubly lucky, of course: We enjoy not only the privilege of existence but also the singular ability to appreciate it and even, in a multitude of ways, to make it better. It is a talent we have only barely begun to grasp.

~ Bill Bryson

Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.

~ Charles Darwin

Were these boys in their right minds? Here were two boys with good intellect, one eighteen and one nineteen. They had all the prospects that life could hold out for any of the young; one a graduate of Chicago and another of Ann Arbor; one who had passed his examination for the Harvard Law School and was about to take a trip in Europe,--another who had passed at Ann Arbor, the youngest in his class, with three thousand dollars in the bank. Boys who never knew what it was to want a dollar; boys who could reach any position that was to boys of that kind to reach; boys of distinguished and honorable families, families of wealth and position, with all the world before them. And they gave it all up for nothing, for nothing! They took a little companion of one of them, on a crowded street, and killed him, for nothing, and sacrificed everything that could be of value in human life upon the crazy scheme of a couple of immature lads.Now, your Honor, you have been a boy; I have been a boy. And we have known other boys. The best way to understand somebody else is to put yourself in his place.Is it within the realm of your imagination that a boy who was right, with all the prospects of life before him, who could choose what he wanted, without the slightest reason in the world would lure a young companion to his death, and take his place in the shadow of the gallows?...No one who has the process of reasoning could doubt that a boy who would do that is not right.How insane they are I care not, whether medically or legally. They did not reason; they could not reason; they committed the most foolish, most unprovoked, most purposeless, most causeless act that any two boys ever committed, and they put themselves where the rope is dangling above their heads....Why did they kill little Bobby Franks?Not for money, not for spite; not for hate. They killed him as they might kill a spider or a fly, for the experience. They killed him because they were made that way. Because somewhere in the infinite processes that go to the making up of the boy or the man something slipped, and those unfortunate lads sit here hated, despised, outcasts, with the community shouting for their blood.. . . I know, Your Honor, that every atom of life in all this universe is bound up together. I know that a pebble cannot be thrown into the ocean without disturbing every drop of water in the sea. I know that every life is inextricably mixed and woven with every other life. I know that every influence, conscious and unconscious, acts and reacts on every living organism, and that no one can fix the blame. I know that all life is a series of infinite chances, which sometimes result one way and sometimes another. I have not the infinite wisdom that can fathom it, neither has any other human brain

~ Clarence Darrow

If we are merely matter intricately assembled, is this really demeaning? If there's nothing here but atoms, does that make us less or does that make matter more?

~ Carl Sagan

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?

~ James Frey

In every remote corner of the world there are people like Carl Jones and Don Merton who have devoted their lives to saving threatened species. Very often, their determination is all that stands between an endangered species and extinction.But why do they bother? Does it really matter if the Yangtze river dolphin, or the kakapo, or the northern white rhino, or any other species live on only in scientists' notebooks?Well, yes, it does. Every animal and plant is an integral part of its environment: even Komodo dragons have a major role to play in maintaining the ecological stability of their delicate island homes. If they disappear, so could many other species. And conservation is very much in tune with our survival. Animals and plants provide us with life-saving drugs and food, they pollinate crops and provide important ingredients or many industrial processes. Ironically, it is often not the big and beautiful creatures, but the ugly and less dramatic ones, that we need most.Even so, the loss of a few species may seem irrelevant compared to major environmental problems such as global warming or the destruction of the ozone layer. But while nature has considerable resilience, there is a limit to how far that resilience can be stretched. No one knows how close to the limit we are getting. The darker it gets, the faster we're driving.There is one last reason for caring, and I believe that no other is necessary. It is certainly the reason why so many people have devoted their lives to protecting the likes of rhinos, parakeets, kakapos, and dolphins. And it is simply this: the world would be a poorer, darker, lonelier place without them.

~ Mark Carwardine

We are biology. We are reminded of this at the beginning and the end, at birth and at death. In between we do what we can to forget.

~ Mary Roach

But there is nothing in biology yet found that indicates the inevitability of death.

~ Richard Feynman

Thus, by science I mean, first of all, a worldview giving primacy to reason and observation and a methodology aimed at acquiring accurate knowledge of the natural and social world. This methodology is characterized, above all else, by the critical spirit: namely, the commitment to the incessant testing of assertions through observations and/or experiments — the more stringent the tests, the better — and to revising or discarding those theories that fail the test. One corollary of the critical spirit is fallibilism: namely, the understanding that all our empirical knowledge is tentative, incomplete and open to revision in the light of new evidence or cogent new arguments (though, of course, the most well-established aspects of scientific knowledge are unlikely to be discarded entirely).. . . I stress that my use of the term 'science' is not limited to the natural sciences, but includes investigations aimed at acquiring accurate knowledge of factual matters relating to any aspect of the world by using rational empirical methods analogous to those employed in the natural sciences. (Please note the limitation to questions of fact. I intentionally exclude from my purview questions of ethics, aesthetics, ultimate purpose, and so forth.) Thus, 'science' (as I use the term) is routinely practiced not only by physicists, chemists and biologists, but also by historians, detectives, plumbers and indeed all human beings in (some aspects of) our daily lives. (Of course, the fact that we all practice science from time to time does not mean that we all practice it equally well, or that we practice it equally well in all areas of our lives.)

~ Alan Sokal

The biological equipment of a man rigidly restricts the field in which he can serve.

~ Ludwig Von Mises

All our sentiments - religious, romantic or any other - are born in the neurons.

~ Abhijit Naskar

Biologically speaking, you are the child of Mother Nature, and neurologically speaking, you are the heirs of immortal bliss.

~ Abhijit Naskar

We gain from the new science of mind not only insights into ourselves - how we perceive, learn, remember, feel, believe and act - but also a new perspective of ourselves and our fellow human beings in the context of biological evolution.

~ Abhijit Naskar

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

~ Jonas Salk

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

Dream is not that which you see while sleeping it is something that does not let you sleep.

~ A.p.j. Abdul Kalam

The total amount of suffering per year in the natural world is beyond all decent contemplation. During the minute that it takes me to compose this sentence, thousands of animals are being eaten alive, many others are running for their lives, whimpering with fear, others are slowly being devoured from within by rasping parasites, thousands of all kinds are dying of starvation, thirst, and disease. It must be so. If there ever is a time of plenty, this very fact will automatically lead to an increase in the population until the natural state of starvation and misery is restored. In a universe of electrons and selfish genes, blind physical forces and genetic replication, some people are going to get hurt, other people are going to get lucky, and you won't find any rhyme or reason in it, nor any justice. The universe that we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil, no good, nothing but pitiless indifference.

~ Richard Dawkins

One general law, leading to the advancement of all organic beings, namely, multiply, vary, let the strongest live and the weakest die.

~ Charles Darwin

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

~ Charles Darwin

In a very real sense we have two minds, one that thinks and one that feels

~ Daniel Goleman

Every time you understand something, religion becomes less likely. Only with the discovery of the double helix and the ensuing genetic revolution have we had grounds for thinking that the powers held traditionally to be the exclusive property of the gods might one day be ours. . . .

~ James D. Watson

DNA is like a computer program but far, far more advanced than any software ever created.

~ Bill Gates

Nothing in biology makes sense except in the light of evolution.

~ Theodosius Dobzhansky

A god who is capable of sending intelligible signals to millions of people simultaneously, and of receiving messages from all of them simultaneously, cannot be, whatever else he might be, simple. Such Bandwidth!

~ Richard Dawkins

Perhaps eggs are like neurons, which also are not replenished in adulthood: they know too much. Eggs must plan the party. Sperm need only to show up- wearing top hat and tails, of course.

~ Natalie Angier

In the abstract, it might be tempting to imagine that irreducible complexity simply requires multiple simultaneous mutations - that evolution might be far chancier than we thought, but still possible. Such an appeal to brute luck can never be refuted... Luck is metaphysical speculation; scientific explanations invoke causes.

~ Michael J. Behe

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?

~ Jacques Monod

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

To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I confess, absurd in the highest degree...The difficulty of believing that a perfect and complex eye could be formed by natural selection , though insuperable by our imagination, should not be considered subversive of the theory.

~ Charles Darwin

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.

~ Michael J. Behe

The fundamental claim of intelligent design is straightforward and easily intelligible: namely, there are natural systems that cannot be adequately explained in terms of undirected natural forces and that exhibit features which in any other circumstance we would attribute to intelligence.

~ William A. Dembski

To put it bluntly but fairly, anyone today who doubts that the variety of life on this planet was produced by a process of evolution is simply ignorant—inexcusably ignorant, in a world where three out of four people have learned to read and write.

~ Daniel C. Dennett

Is the conclusion that the universe was designed - and that the design extends deeply into life - science, philosophy, religion, or what? In a sense it hardly matters. By far the most important question is not what category we place it in, but whether a conclusion is true. A true philosophical or religious conclusion is no less true than a true scientific one. Although universities might divide their faculty and courses into academic categories, reality is not obliged to respect such boundaries.

~ Michael J. Behe

Teaching students the evidence for and against Darwinism is not the same as teaching intelligent design. The U.S. Congress has officially endorsed teaching students 'the full range of scientific views' about Darwinian evolution.

~ Jonathan Wells

Genetics might be adequate for explaining microevolution, but microevolutionary changes in gene frequency were not seen as able to turn a reptile into a mammal or to convert a fish into an amphibian. Microevolution looks at adaptations that concern the survival of the fittest, not the arrival of the fittest... The origin of species — Darwin’s problem — remains unsolved.

~ Scott F. Gilbert

No fossil is buried with its birth certificate. That, and the scarcity of fossils, means that it is effectively impossible to link fossils into chains of cause and effect in any valid way... To take a line of fossils and claim that they represent a lineage is not a scientific hypothesis that can be tested, but an assertion that carries the same validity as a bedtime story—amusing, perhaps even instructive, but not scientific.

~ Henry Gee

The idea that one can go to the fossil record and expect to empirically recover an ancestor-descendant sequence, be it of species, genera, families, or whatever, has been, and continues to be, a pernicious illusion.

~ Gareth J. Nelson

I am quite sure that our views on evolution would be very different had biologists studied genetics and natural selection before and not after most of them were convinced that evolution had occurred.

~ J.b.s. Haldane
