The complexity of the simplest known type of cell is so great that it is impossible to accept that such an object could have been thrown together suddenly by some kind of freakish, vastly improbable, event. Such an occurrence would be indistinguishable from a miracle.

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

We all know interspecies romance is weird.

Natural selection is a mechanism for generating an exceedingly high degree of improbability.

I’ve always liked all the sciences, like math, physics and biology.

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

Hitherto, no rival hypothesis has been proposed as a substitute for the doctrine of transmutation; for ‘independent creation,’ as it is often termed, or the direct intervention of the Supreme Cause, must simply be considered as an avowal that we deem the question to lie beyond the domain of science.

Even today a good many distinguished minds seem unable to accept or even to understand that from a source of noise natural selection alone and unaided could have drawn all the music of the biosphere. In effect natural selection operates upon the products of chance and can feed nowhere else; but it operates in a...

Those who have dissected or inspected many [bodies] have at least learnt to doubt; while others who are ignorant of anatomy and do not take the trouble to attend it are in no doubt at all.

My laboratory is interested in the related challenges of understanding the origin of life on the early earth, and constructing synthetic cellular life in the laboratory. Focusing on artificial life frees us to explore novel chemical systems, but what we learn from these systems helps us to understand possible pathways leading to the origin of...

Every day, hundreds of observations and experiments pour into the hopper of the scientific literature. Many of them don’t have much to do with evolution – they’re observations about the details of physiology, biochemistry, development, and so on – but many of them do. And every fact that has something to do with evolution confirms...

The externalization of memory [via the use of external symbolic storage systems] has altered the actual memory architecture within which humans think, which is changing the role of biological memory, the way in which the human brain deploys its resources, and the form of modern culture.

The cell, this elementary keystone of living nature, is far from being a peculiar chemical giant molecule or even a living protein and as such is not likely to fall prey to the field of an advanced chemistry. The cell is itself an organism, constituted of many small units of life.

The extracellular genesis of cells in animals seemed to me, ever since the publication of the cell theory [of Schwann], just as unlikely as the spontaneous generation of organisms. These doubts produced my observations on the multiplication of blood cells by division in bird and mammalian embryos and on the division of muscle bundles in...

Living organisms were not independently created, but have descended and diversified over time from common ancestors. And thus, no other biological theory so elegantly explains this. Evolutionary theory has withstood the test of time—by way of vicarious experimentation, observation, analysis, and relentless criticism, though opposing viewpoints still cling to the concept of “design.” As a...

I recently asked more than seventy eminent researchers if they would have done I their work differently if they had thought Darwin’s theory was wrong. The responses were all the same: no. I also examined the outstanding biodiscoveries of the past century: the discovery of the double helix; the characterization of the ribosome: the mapping...

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...

All human movement is expressive.

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

Suddenly I realized that a cell’s life is controlled by the physical and energetic environment and not by its genes. Genes are simply molecular blueprints used in the construction of cells, tissues, and organs. The environment serves as a “contractor” who reads and engages those genetic blueprints and is ultimately responsible for the character of...

Darwin was a biological evolutionist, because he was first a uniformitarian geologist. Biology is pre-eminent to-day among the natural sciences, because its younger sister, Geology, gave it the means.

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...

Man is a product of nature, a part of the Universe. The Universe is operated under exact natural laws. Man is a product of millions of years of evolution. He adapts himself to the laws of nature or he perishes.

Politics is applied biology.

Nature has but one plan of operation, invariably the same in the smallest things as well as in the largest, and so often do we see the smallest masses selected for use in Nature, that even enormous ones are built up solely by fitting these together. Indeed, all Nature’s efforts are devoted to uniting the...

…But I own that I cannot see as plainly as others do, and as I should wish to do, evidence of design and beneficence on all sides of us. There seems to me too much misery in the world. I cannot persuade myself that a beneficent and omnipotent God would have designedly created the Ichneumonidæ...

It was in the attempt to ascertain the interrelationships between species that experiments n genetics were first made. The words “evolution” and “origin of species” are now so intimately associated with the name of Darwin that we are apt to forger that the idea of common descent had been prominent in the mnds of naturalists...

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

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.

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

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.

One of the central mysteries of biology is why the genome is largely identical from cell to cell, even though cells do different things.

When in 1863 Thomas Huxley coined the phrase ‘Man’s Place in Nature,’ it was to name a short collection of his essays applying to man Darwin’s theory of evolution. The Origin of Species had been published only four years before, and the thesis that man was literally a part of nature, rather than an earthy...

An attempt to study the evolution of living organisms without reference to cytology would be as futile as an account of stellar evolution which ignored spectroscopy.

The evolutionists, piercing beneath the show of momentary stability, discovered, hidden in rudimentary organs, the discarded rubbish of the past. They detected the reptile under the lifted feathers of the bird, the lost terrestrial limbs dwindling beneath the blubber of the giant cetaceans. They saw life rushing outward from an unknown center, just as today...

Every hour of your life that ticks by, there are numerous points and moments when you can choose to pause – and be aware of your mental and physical state. At any given point, you can freeze the flow that is your life, and be fully conscious for a moment.

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

Molecular biology has shown that even the simplest of all living systems on the earth today, bacterial cells, are exceedingly complex objects. Although the tiniest bacterial cells are incredibly small, weighing less than 10-12 gms, each is in effect a veritable micro-miniaturized factory containing thousands of exquisitely designed pieces of intricate molecular machinery, made up...

The stuff of life turned out to be not a quivering, glowing, wondrous gel but a contraption of tiny jigs, springs, hinges, rods, sheets, magnets, zippers, and trapdoors, assembled by a data tape whose information is copied, downloaded and scanned.

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!

soup.” In this primeval soup, by infinite variations of lifeless growth and decay of substances during some billions of years, the way of life was ultimately reached, with its metabolism characterized by selective assimilation and dissimilation as end stations of a sluiced and canalized flow of free chemical energy.

The emotional mind likewise transcends the facile and appealing dualism separating its psychological and biological aspects. Physical mechanisms produce one’s experience of the world. Experience, in turn, remodels the neurons whose chemoelectric messages create consciousness. Selecting one strand of that eternal braid and assigning it primacy is the height of capriciousness. (168)

Oh I believe in loving cats and dogs and children and parents – sometimes – but I don’t believe in romantic love. Of course, there’s the momentary rush of hormones and chemicals that encourages us to mate, but it’s biology – it’s no more inherently mystical than the nicotine in that cigarette you’re smoking

Each species may have had its origin in a single pair, or individual, where an individual was sufficient, and species may have been created in succession at such times and in such places as to enable them to multiply and endure for an appointed period, and occupy an appointed space on the globe.

When one ponders on the tremendous journey of evolution over the past three billion years or so, the prodigious wealth of structures it has engendered, and the extraordinarily effective teleonomic performances of living beings from bacteria to man, one may well find oneself beginning to doubt again whether all this could conceivably be the product...

I know that certain minds would regard as audacious the idea of relating the laws which preside over the play of our organs to those laws which govern inanimate bodies; but, although novel, this truth is none the less incontestable. To hold that the phenomena of life are entirely distinct from the general phenomena of...

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.

Insects are major players in nature’s recycling effort, and in nature a corpse is simply organic matter to be recycled. Left to its own devices, nature quickly populates a corpse with a diverse community of organisms, all dedicated to reducing the body to its basic components.

According to the concept of transformational evolution, first clearly articulated by Lamarck, evolution consists of the gradual transformation of organisms from one condition of existence to another.
