Top 170 Quotes & Sayings by Famous Biologists - Page 2

In every outthrust headland, in every curving beach, in every grain of sand there is the story of the earth.

I am always more interested in what I am about to do than what I have already done.

The most alarming of all man's assaults upon the environment is the contamination of air, earth, rivers, and sea with dangerous and even lethal materials.

There are a whole other range of sciences that must deal with the narrative reconstruction of the inordinately complex events of history that can occur but once in their detailed glory. And for those kinds of sciences, be it cosmology, or evolutionary biology, or geology, or palaeontology, the experimental methods, simplification, quantification, prediction and repetition of the experimental sciences don't always work. You have to go with the narrative, the descriptive methods of what? Of historians.

If having endured much, we at last asserted our 'right to know' and if, knowing, we have concluded that we are being asked to take senseless and frightening risks, then we should no longer accept the counsel of those who tell us that we must fill our world with poisonous chemicals, we should look around and see what other course is open to us.

One way to open your eyes is to ask yourself, "What if I had never seen this before? What if I knew i would never see it again?

Since Pawlow [Pavlov] and his pupils have succeeded in causing the secretion of saliva in the dog by means of optic and acoustic signals, it no longer seems strange to us that what the philosopher terms an 'idea' is a process which can cause chemical changes in the body.

No hint of genuine charity ameliorates our vision of society, once sentimentalism has been laid side. What passes for cooperation turns out to be a mixture of opportunism and exploitation. Scratch an altruist and watch a hypocrite bleed.

We are not truly civilized if we concern ourselves only with the relation of man to man. What is important is the relation of man to all life.

Those who contemplate the beauty of the earth find reserves of strength that will endure as long as life lasts.

Besides, the sense of safety offered by bottled water is a mirage. It turns out that breathing, not drinking, constitutes our main route of exposure to volatile pollutants in tap water, such as solvents, pesticides, and byproducts of water chlorination. As soon as the toilet is flushed or the faucet turned on-or the bathtub, the shower, the humidifier, the washing machine-these contaminants leave the water and enter the air. A recent study shows that the most efficient way of exposing yourself to chemical contaminants in tap water is to turn on a dishwasher.

The study of how substances alter gene expression is part of the field of epigenetics. Some chemical exposures appear to turn on and turn off genes in ways that disregulate cell growth and predispose for cancer. From this perspective, our genes are less the command-and-control masters of our cells and more like the keys of piano, with the environment as the hands of the pianist.

As an American I must say I haven't been very encouraged by the way in which the people who run the government in the United States have been listening to those contrary voices. And so long as the power to run the world lies in the hands of people who are quite happy to see it get warmer, or fuel be used more, then would those people who oppose it are crying in the wilderness - that's the real problem.

[M]any people would accept that we do not really have knowledge of the world; we have knowledge only of our representations of the world. Yet we seem condemned by our consitution to treat these representations as if they were the world, for our everyday experience feels as if it were of a given and immediate world.

As currently written, the laws require certain manufacturers and users of such chemicals to report any and all environmental releases-either accidental or routine-to air, water, or soil. The Toxics Release Inventory is the main registry of such events, and it is available to the public through the Environmental Protection Agency. It is hardly comprehensive. Toxic emissions reported to the federal government are thought to account for only 5 percent of all chemical releases.

If we're going to make a politically responsible and a scientifically sensible claim it should not be stop the world exactly where it is because that's not possible. It has to be to decide what kind of world do we as human beings want to live in.

Those who contemplate the beauty of the earth find reserves of strength that will endure as long as life lasts. There is something infinitely healing in the repeated refrains of nature -- the assurance that dawn comes after night, and spring after winter.

Nature reserves some of her choice rewards for days when her mood may appear to be somber.

Only as a child's awareness and reverence for the wholeness of life are developed can his humanity to his own kind reach its full development.

When the wrong question is being asked, it usually turns out to be because the right question is too difficult. Scientists ask questions they can answer. That is, it is often the case that the operations of a science are not a consequence of the problematic of that science, but that the problematic is induced by the available means.

A couple in love walking along the banks of the Seine are, in real fact, a couple in love walking along the banks of the Seine, not mere particles in motion.

Nowhere on the shore is the relation of a creature to its surroundings a matter of a single cause and effect; each living thing is bound to its world by many threads, weaving the intricate design of the fabric of life.

My general impression about people like Steve Gould and Carl Sagan and so on is that when they disappear as individuals and are no longer appearing on the stage and they are no longer writing, that their lifetime of acknowledgement by the general reading public is not very long... There were many people in the 19th century who were equally famous people who gave working man's lectures, supporters of Darwin, we as scholars know their names but the general public never heard of them.

A few years ago, they [Neandertals] were thought to be ancestral to anatomically modern humans, but now we know that modern humans appeared at least 100,000 years ago, much before the disappearance of the Neandertals. Moreover, in caves in the Middle East, fossils of modern humans have been found dated 120,000-100,000 years ago, as well as Neandertals dated at 60,000 and 70,000 years ago, followed again by modern humans dated at 40,000 years ago. It is unclear whether the two forms repeatedly replaced one another by migration from other regions, or whether they coexisted in some areas

The primary problem is not to provide the public with the knowledge of how far it is to the nearest star and what genes are made of .. Rather, the problem is to get them to reject irrational and supernatural explanations of the world, the demons that exist only in their imaginations, and to accept a social and intellectual apparatus, Science, as the only begetter of truth.

We still talk in terms of conquest. We still haven't become mature enough to think of ourselves as only a tiny part of a vast and incredible universe.

Now I truly believe that we in this generation must come to terms with nature, and I think we're challenged, as mankind has never been challenged before, to prove our maturity and our mastery, not of nature but of ourselves.

If you can't write well then your ambition to become famous in this way will be frustrated. Either that or you have to get an amanuensis who will write for you.

Toby Tyrrell unravels the various formulations of Gaia and explains how recent scientific developments bring the hypothesis into question. His criticisms are insightful, profound, and convincing, but fair. On Gaia is wonderfully informative and a pleasure to read.

Through the discovery of Buchner, Biology was relieved of another fragment of mysticism. The splitting up of sugar into CO2 and alcohol is no more the effect of a 'vital principle' than the splitting up of cane sugar by invertase. The history of this problem is instructive, as it warns us against considering problems as beyond our reach because they have not yet found their solution.

The real wealth of the Nation lies in the resources of the earth - soil, water, forests, minerals, and wildlife.

The most alarming of all man's assaults upon the environment is the contamination of air, earth, rivers, and sea with dangerous and even lethal materials. This pollution is for the most part irrecoverable; the chain of evil it initiates not only in the world that must support life but in living tissues is for the most part irreversible. In this now universal contamination of the environment, chemicals are the sinister and little-recognized partners of radiation in changing the very nature of the world-the very nature of its life.

A free society that allows each individual to seek his or her own selfish ends (without deliberately trying to harm anyone else) will produce a state in which everyone's interest is optimized without any individual knowing in advance what that state might be.

In the world outside this glass room, songbirds are feeding and resting in the trees. Some will take off tonight and not land until they reach Venezuela. Sandpipers, plovers, and broad-winged hawks have already left for Patagonia and Panama. Bats are headed for caves in Kentucky and Tennessee. Out in the Atlantic, humpback whales pass by on their way to the Caribbean. Even now, Canada geese are honking toward us from Quebec. It is a good day for the beginnings of journeys.Every time I look at you, I think, Now I cannot die.

Pick up a pinecone and count the spiral rows of scales. You may find eight spirals winding up to the left and 13 spirals winding up to the right, or 13 left and 21 right spirals, or other pairs of numbers. The striking fact is that these pairs of numbers are adjacent numbers in the famous Fibonacci series

Until we have courage to recognize cruelty for what it is - whether its victim is human or animal - we cannot expect things to be much better in the world. There can be no double standard. We cannot have peace among men whose hearts find delight in killing any living creature. By every act that glorifies or even tolerates such moronic delight in killing, we set back the progress of humanity.

The general public doesn't know and probably doesn't care about punctuated equilibria nor indeed should they, or the greenhouse effect on some other planet - they barely have the ability to cope with the greenhouse effect on their own planet. So I think you have to distinguish between the broad visibility of a scientist when he or she is speaking to a general public and trying to address general issues and the continued position that a scientist may have into the history of a particular subject.

Have we fallen into a mesmerized state that makes us accept as inevitable that which is inferior or detrimental, as though having lost the will or the vision to demand that which is good?

If a child is to keep alive his inborn sense of wonder, he needs the companionship of at least one adult who can share it, rediscovering with him the joy, excitement, and mystery of the world we live in.

... we find ourselves facing a rising tide of biologically active, synthetic organic chemicals. Some tinker with our hormones. Some attach themselves to our chromosomes and trigger mutations. Some cripple the immune system. Some light up our genes and so enhance the production of certain enzymes. If we could metabolize these chemicals into completely benign breakdown products and excrete them, they would pose less of a hazard. Instead, a good many of them accumulate.

In my mind the job of a natural scientist is to bend over backwards to say something which can be demonstrated to be true or at least which is not of such a nature that there's no way to demonstrate that it's false.

We can decide that the presence of cancer-causing substances in our air, water, and food is too expensive. A 2009 study, for example, has found that coal miners in Appalachia costs the region five times more in premature deaths, including from cancer, than it provides to the region in jobs, taxes, and economic benefits. In California, the production and use of hazardous chemicals cost the state $2.6 billion in 2004 alone in lost wages and health-care expenses to treat workers and children with pollution-linked diseases.

The cybernetics phase of cognitive science produced an amazing array of concrete results, in addition to its long-term (often underground) influence

A rainy day is the perfect time for a walk in the woods.

Mountains and deserts, with their sparse life at the limit of existence, make one restless and disconsolate; one becomes an explorer in an intellectual realm as well as in a physical one.

I watched the coral reefs that I studied as a student vanish in the blink of an eye, and for decades I wrote and spoke of ocean obituaries. But big scary problems without solutions lead to apathy, not action.

There is no drop of water in the ocean, not even in the deepest parts of the abyss, that does not know and respond to the mysterious forces that create the tide.

Scratch an altruist and watch a hypocrite bleed.

There is a strong current in contemporary culture advocating ' holistic ' views as some sort of cure-all... Reductionism implies attention to a lower level while holistic implies attention to higher level. These are intertwined in any satisfactory description: and each entails some loss relative to our cognitive preferences, as well as some gain... there is no whole system without an interconnection of its parts and there is no whole system without an environment.

There is something infinitely healing in the repeated refrains of nature.

If everybody would agree that their current reality is A reality, and that what we essentially share is our capacity for constructing a reality, then perhaps we could all agree on a meta-agreement for computing a reality that would mean survival and dignity for everyone on the planet, rather than each group being sold on a particular way of doing things.

An experimental science is supposed to perform experiments that find generalities. It's not just supposed to tally up a long list of individual cases and their unique life histories. That's butterfly collecting.

It's the excitement of being on the frontier.

From the right to know and the duty to inquire flows the obligation to act.

We take the side of science in spite of the patent absurdity of some of its constructs, in spite of its failure to fulfill many of its extravagant promises of health and life, in spite of the tolerance of the scientific community for unsubstantiated just-so stories, because we have a prior commitment, a commitment to materialism... We cannot allow a Divine Foot in the door.

To stand at the edge of the sea, to sense the ebb and flow of the tides, to feel the breath of a mist moving over a great salt marsh, to watch the flight of shore birds that have swept up and down the surf lines of the continents for untold thousands of years, to see the running of the old eels and the young shad to the sea, is to have knowledge of things that are as nearly eternal as any earthly life can be.

In nature nothing exists alone.

Error is part of the overhead of doing research

We do have tendency, now in biology especially to make up stories, to make theoretical biology a kind of game, in fact we have game theory in biology which is meant to use the theory of games to make predictions or explain things.

Quantification, experimentation, rigor, repetition, prediction - all of these are part of the experimental sciences. There's an iconography also namely man, and I do mean males in white coats who spin dials and wait for numbers to appear.
