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

There can be no doubt that the existing Fauna and Flora is but the last term of a long series of equally numerous contemporary species, which have succeeded one another, by the slow and gradual substitution of species for species, in the vast interval of time which has elapsed between the deposition of the earliest fossiliferous strata and the present day.

Thomas Henry Huxley

All organisms vary. It is in the highest degree improbable that any given variety should have exactly the same relations to surrounding conditions as the parent stock. In that case it is either better fitted (when the variation may be called useful), or worse fitted, to cope with them. If better, it will tend to supplant the parent stock; if worse, it will tend to be extinguished by the parent stock.If (as is hardly conceivable) the new variety is so perfectly adapted to the conditions that no improvement upon it is possible,—it will persist, because, though it does not cease to vary, the varieties will be inferior to itself.If, as is more probable, the new variety is by no means perfectly adapted to its conditions, but only fairly well adapted to them, it will persist, so long as none of the varieties which it throws off are better adapted than itself.On the other hand, as soon as it varies in a useful way, i.e. when the variation is such as to adapt it more perfectly to its conditions, the fresh variety will tend to supplant the former.

Thomas Henry Huxley

The secrets of evolution, are time and death. There's an unbroken thread that stretches from those first cells to us.

Carl Sagan

Today, the theory of evolution is an accepted fact for everyone but a fundamentalist minority, whose objections are based not on reasoning but on doctrinaire adherence to religious principles.

James D. Watson

...I suspect everyone there can reason along the lines I described...It's just that when it comes to evolution, and especially to the related realization that we are all pretty small bits of the universe, it seems as though Ham and his followers just can't handle the truth. They throw aside their common sense and cling to the hope that there's something that makes it okay to *not* think for themselves.""The irony is, in the process they are walking away from our ability to understand who we are, where we came from, and how we fit into a cosmos...If there is something divine in our nature, something that sets humans apart from all creatures, surely our ability to reason is a key part of it. The irony is, in the process they are walking away from our ability to understand who we are, where we came from, and how we fit into a cosmos...If there is something divine in our nature, something that sets humans apart from all creatures, surely our ability to reason is a key part of it.

Bill Nye

However life started, once established, it persisted for over 3.5 billion years and evolved from microbial slime to the sophistication of human civilization.

David C. Catling

How thoroughly the chimps and bonobos have erased the list of purported human distinctions!-self-awareness, language, ideas and their association, reason, trade, play, choice, courage, love and altruism, laughter, concealed ovulation, kissing, face-to-face sex, female orgasm, division of labor, cannibalism, art, music, politics, and featherless bipedalism, besides tool using, tool making, and much else. Philosophers and scientists confidently offer up traits said to be uniquely human, and the apes casually knock them down--toppling the pretension that humans constitute some sort of biological aristocracy among the beings of Earth. Instead, we are more like the nouveau riche, incompletely accommodated to our recent exalted state, insecure about who we are, and trying to put as much distance as possible between us and our humble origins. It's as if our nearest relatives, by their very existence, refute all our explanations and justifications. So as counterweights to human arrogance and pride, it is good for us that there are still apes on Earth.

Carl Sagan

The myosin in our own skeletal muscles is more closely related to the myosin driving the flight muscles of that irritating housefly buzzing around your head than it is to the myosin in the muscles of your own sphincters

Nick Lane

All social animals, including people, live under constant pressure from two competing interests: protecting themselves from others and aligning themselves with others. When these two interests are balanced, the result is dynamic social homeostasis.

Mystery

It is high time that we grew up and left the Garden. We are indeed Eden’s children, yet it is time to place Genesis alongside the geocentric myth in the basket of stories that once, in a world of intellectual naivete, made helpful sense. As we walk through the gates, aware of the dazzling richness of the genuine biological world, there might even be a smile on the Creator’s face — that at long last His creatures have learned enough to understand His world as it truly is.

Kenneth R. Miller

If about a dozen genera of birds had become extinct or were unknown, who would have ventured to have surmised that birds might have existed which used their wings solely as flappers, like the logger-headed duck (Micropterus of Eyton); as fins in the water and front legs on the land, like the penguin; as sails, like the ostrich; and functionally for no purpose, like the Apteryx. Yet the structure of each of these birds is good for it, under the conditions of life to which it is exposed, for each has to live by a struggle; but it is not necessarily the best possible under all possible conditions. It must not be inferred from these remarks that any of the grades of wing-structure here alluded to, which perhaps may all have resulted from disuse, indicate the natural steps by which birds have acquired their perfect power of flight; but they serve, at least, to show what diversified means of transition are possible.

Charles Darwin

We should not be too quick to dismiss our own [ocular] arrangement. As so often in biology, the situation is more complex.....we have the advantage that our own light-sensitive cells are embedded directly in their support cells (the retinal pigment epithelium) with an excellent blood supply immediately underneath. Such an arrangement supports the continuous turnover of photosensitive pigments. The human retina consumes even more oxygen than the brain, per gram, making it the most energetic organ in the body.

Nick Lane

What, after all, is so special about genes? The answer is that they are replicators. The laws of physics are supposed to be true all over the accessible universe. Are there any principles of biology which are likely to have similar universal validity? When astronauts voyage to distant planets and look for life, they can expect to find creatures too strange and unearthly for us to imagine. But is there anything which must be true of all life, wherever it is found, and whatever the basis of its chemistry? If forms of life exist whose chemistry is based on silicon rather than carbon, or ammonia rather than water, if creatures are discovered which boil to death at -100 degrees centigrade, if a form of life is found which is not based on chemistry at all, but on electronic reverberating circuits, will there still be any general principle which is true of all life? Obviously I do not know but, if I had to bet, I would put my money on one fundamental principle. This is the law that all life evolves by the differential survival of replicating entities. The gene, the DNA molecule, happens to be the replicating entity which prevails on our own planet. There may be others. If there are, provided certain conditions are met, they will almost inevitably tend to becometthe basis for an evolutionary process.

Richard Dawkins

Man is the result of a purposeless and natural process that did not have him in mind.

George Gaylord Simpson

The essential quality that an entity needs, if it is to become an effective gene vehicle, is this. It must have an impartial exit channel into the future, for all the genes inside it. This is true of an individual wolf. The channel is the thin stream of sperms, or eggs, which it manufactures by meiosis. It is not true of the pack of wolves. Genes have something to gain from selfishly promoting the welfare of their own individual bodies, at the expense of other genes in the wolf pack. A bee-hive, when it swarms, appears to reproduce by broad-fronted budding, like a wolf pack. But if we look more carefully we find that, as far as the genes are concerned, their destiny is largely shared. The future of the genes in the swarm is, at least to a large extent, lodged in the ovaries of one queen. This is why—it is just another way of expressing the message of earlier chapters—the bee colony looks and behaves like a truly integrated single vehicle.

Richard Dawkins

The greatest impact of the Darwinian revolution...was that it completed the liberation from superstition and fear that began in the physical sciences a few centuries before. Man, too, is a natural phenomenon. [in "The evolutionary concept of man", 1972, p. 35.]

George Gaylord Simpson

Every question leads to new answers, new discoveries, and new smarter questions.

Bill Nye

The best scientists can do is fail to disprove things while pointing to how hard they tried

Richard Dawkins

All life evolves by the differential survival of replicating entities

Richard Dawkins

The story of evolution is more dramatic, more compelling, more intricate than any creation myth. Yet like any creation myth, it is a tale of transformations, of sudden and spectacular changes, eruptions of innovation that transfigured our planet, overwriting past revolutions with new layers of complexity. The tranquil beauty of our planet from space belies the real history of this place, full of strife and ingenuity and change. How ironic that our own petty squabbles reflect our planet's turbulent past, and that we alone, despoilers of the Earth, can rise above it to see the beautiful unity of the whole.

Nick Lane

The lesson of every extinction, says the Smithsonian’s Doug Erwin, is that we can’t predict what the world will be 5 million years later by looking at the survivors."There will be plenty of surprises. Let’s face it: who would’ve predicted the existence of turtles? Who would ever have imagined that an organism would essentially turn itself inside out, pulling its shoulder girdle inside its ribs to form a carapace? If turtles didn’t exist, no vertebrate biologist would’ve suggested that anything would do that: he’d have been laughed out of town. The only real prediction you can make is that life will go on. And that it will be interesting.

Alan Weisman

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

If a functional gene becomes a pseudogene, its product will no longer be available to the biochemical pathways in which it formerly participated. The transformation of a gene to a pseudogene will not have catastrophic consequences if the biochemical pathways in which its product formerly participated are redundantly complex—other products can take over the role of the missing product. Perhaps not as efficiently, but efficiency is something that can be improved by selection. In this way, redundant scaffolding can be reduced, ultimately to the point where a system or pathway is irreducibly complex.

Niall Shanks

If then the question is put to me whether I would rather have a miserable ape for a grandfather or a man highly endowed by nature and possessed of great means of influence and yet employs these faculties and that influence for the mere purpose of introducing ridicule into a grave scientific discussion, I unhesitatingly affirm my preference for the ape.

Thomas Henry Huxley

When I view all beings not as special creations, but as the lineal descendants of some few beings which lived long before the first bed of the Silurian system was deposited, they seem to me to become ennobled.

Charles Darwin

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

Many evolutionists today... continually promote the idea that 'Big Change = Small Change x Millions of Years'. This is logical fallacy... It is akin to saying "because a cow can jump over a fence, it it only a matter of time and practice for it to jump over the moon.

Dr. Donald Batten

Deteriorated science is a cult, so is imitative or deteriorated Sufism.

Idries Shah

Ossa autem alia quae sunt infra basilare non bene ad sensum apparent nisi ossa illa decoquantur, sed propter peccatum dimitiere consuevi. [The bones which are below the os basilare cannot be well seen unless they are removed and boiled, but owing to the sin involved in this I am accustomed to pass them by.]

Mondino de' Liuzzi Mondino dei Luzzi Mundinus de Leuciis

[It] is hardly possible to maintain seriously that the evil done by science is not altogether outweighed by the good. For example, if ten million lives were lost in every war, the net effect of science would still have been to increase the average length of life.

G H Hardy

Moreover, the sciences are monuments devoted to the public good; each citizen owes to them a tribute proportional to his talents. While the great men, carried to the summit of the edifice, draw and put up the higher floors, the ordinary artists scattered in the lower floors, or hidden in the obscurity of the foundations, must only seek to improve what cleverer hands have created.

Charles-Augustin de Coulomb

Human milk is like ice cream, penicillin, and the drug ecstasy all wrapped up in two pretty packages.

Florence Williams

Men of science offer us health, an obvious benefit; it is only afterwards that we discover that by health, they mean bodily slavery and spiritual tedium.

G.K. Chesterton

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

Staring at the blue sky causes insomnia to occur in the human.

Steven Magee

Arguably the greatest technological triumph of the century has been the public-health system, which is sophisticated preventive and investigative medicine organized around mostly low- and medium-tech equipment; ... fully half of us are alive today because of the improvements.

Richard Rhodes

There is a saying in the medical profession 'Inside everytablet is a little bit of poison'. Avoid medications if you can.

Steven Magee

The radiation detoxification process exists in nature. It is called: Hibernation.

Steven Magee

It is my assessment that most police officers who spend their days driving around USA cities will have some levelof radiation sickness and this is concerning!

Harmonics are the cancer of the electrical system.

Steven Magee

Radio Wave Sickness and Electromagnetic Hypersensitivity are easily preventable and one can only wonder how much longer the insanity of modern governments is going to be allowed to continue in this area.

Steven Magee

It costs about the same to house a maximum-security young adult prisoner for a year as it does to send his law-abiding counterpart to Harvard.

Robert Martensen

People who are dependent are merely using alcohol as a crutch to get through the day. Yet doctors and scientists are still treating "alcoholism" as if it is the problem, when it has nothing to do with the problem. They might as well be studying "scratchism" for people who have a chronic itch.

Chris Prentiss

Health is wealth but being wealthy does not mean one is healthy.

Osunsakin Adewale

Health is wealth but wealth is not health

Osunsakin Adewale

No doctor knows everything. There's a reason why it's called "practising" medicine.

Anonymous

Mine is a gruesome job, but for a scientist with a love for the mechanics of the human body, a great one.

Judy Melinek

....All of the medicine hurts.

Farooq A. Shiekh

We can taste what's in our mouths, touch what's within our reach, smell within hundreds of metres and hear within tens of miles. But it's only through our vision that we are in communication with the sun and stars.

Gavin Francis

He(Prophet Muhammad) laid the foundation of a universal government. His law was one for all. Equal justice and love for everyone.

B. Margoliouth

I've been in auditions without screens, and I can assure you that I was prejudiced. I began to listen with my eyes, and there is no way that your eyes don't affect your judgement. The only true way to listen is with your ears and your heart. (p.251)

Malcolm Gladwell

Any constituency that needs amending, is a prototype in error.

Justin K. McFarlane Beau

To him [Faraday], as to all true philosophers, the main value of a fact was its position and suggestiveness in the general sequence of scientific truth.

John Tyndall

In preparing the present volume, it has been the aim of the author to do full justice to the ample material at his command, and, where possible, to make the illustrations tell the main story to anatomists. The text of such a memoir may soon lose its interest, and belong to the past, but good figures are of permanent value. [Justifying elaborate illustrations in his monographs.]

Othniel Charles Marsh

I looked for it [heavy hydrogen, deuterium] because I thought it should exist. I didn't know it would have industrial applications or be the basic for the most powerful weapon ever known [the nuclear bomb] ... I thought maybe my discovery might have the practical value of, say, neon in neon s

Harold Urey

[Pure research] is worth every penny it costs.

Harold Urey

... it is shameful that there are so few women in science... In China there are many, many women in physics. There is a misconception in America that women scientists are all dowdy spinsters. This is the fault of men. In Chinese society, a woman is valued for what she is, and men encourage her to accomplishments yet she remains eternally feminine.

Chien-Shiung Wu

Necessity is not the mother of invention. Knowledge and experiment are its parents. It sometimes happens that successful search is made for unknown materials to fill well-recognized and predetermined requirements. It more often happens that the acquirement of knowledge of the previously unknown properties of a material suggests its trial for some new use. These facts strongly indicate the value of knowledge of properties of materials and indicate a way for research.

Willis R. Whitney

I attained a triumph so complete that it is now rare to meet an American with marks of small pox on his face... Benefits are valuable according to their duration and extent... but the benign remedy Vaccination saves millions of lives every century, like the [gift] of the sun, universal and everla
