We’re going to die, and that makes us the lucky ones.

If, again, the most superficial introspection teaches the physiologist that his conscious life is dependent upon the mechanical adjustments of his body, and that inversely his body is subjected with certain limitations to his will, then it only remains for him to make one assumption more, namely, that this mutual interdependence between the spiritual and...

Even if the intelligent design of some structure has been established, it still is a separate question whether a wise, powerful, and beneficent God ought to have designed a complex, information-rich structure one way or another. For the sake of argument, let’s grant that certain designed structures are not simply, as Gould put it, “odd”...

Constrained optimization is the art of compromise between conflicting objectives. This is what design is all about. To find fault with biological design – as Stephen Jay Gould regularly does – because it misses some idealized optimum is therefore gratuitous. Not knowing the objectives of the designer, Gould is in no position to say whether...

Mais de toute façon, engendrer, allaiter ne sont pas des activités, ce sont des fonctions naturelles; aucun projet n’y est engagé; c’est pourquoi la femme n’y trouve pas le motif d’une affirmation hautaine de son existence; elle subit passivement son destin biologique.

La fécondité absurde de la femme l’empêchait de participer activement à l’accroissement de ces ressources tandis qu’elle créait indéfiniment de nouveaux besoins.

The known is finite, the unknown infinite; intellectually we stand on an islet in the midst of an illimitable ocean of inexplicability. Our business in every generation is to reclaim a little more land, to add something to the extent and the solidity of our possessions. And even a cursory glance at the history of...

Disease may be defined as ‘A change produced in living things in consequence of which they are no longer in harmony with their environment.

Every single cell in the human body replaces itself over a period of seven years. That means there’s not even the smallest part of you now that was part of you seven years ago.

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...

It is difficult to overstate the importance of understanding mirror neurons and their function. They may well be central to social learning, imitation, and the cultural transmission of skills and attitudes—perhaps even of the pressed-together sound clusters we call words. By hyperdeveloping the mirror-neuron system, evolution in effect turned culture into the new genome. Armed...

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...

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 —...

I stepped to the tank’s edge, leaned in, and concentrated on keeping my eyes open. Which fish would be the shooter? The fish were all facing me, but one in particular seemed to be staring directly at my left eye, like a hunter targeting his prey. Wham! The water hit my pupil with such force...

I think that the formation of [DNA’s] structure by Watson and Crick may turn out to be the greatest developments in the field of molecular genetics in recent years.

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,...

The history of the knowledge of the phenomena of life and of the organized world can be divided into two main periods. For a long time anatomy, and particularly the anatomy of the human body, was the a and ? of scientific knowledge. Further progress only became possible with the discovery of the microscope. A...

Molecular machines display a key signature or hallmark of design, namely, irreducible complexity. In all irreducibly complex systems in which the cause of the system is known by experience or observation, intelligent design or engineering played a role in the origin of the system… We find such systems within living organisms.

The evolution of life, and the evolutionary origin of mankind, are scientifically established as firmly and completely as any historical event not witnessed by human observers. Any concession to anti-evolutionists, suggesting that there are scientific reasons to doubt the facticity of evolution, would be propagating a plain untruth.

An evolutionary perspective of our place in the history of the earth reminds us that Homo sapiens sapiens has occupied the planet for the tiniest fraction of that planet’s four and a half thousand million years of existence. In many ways we are a biological accident, the product of countless propitious circumstances. As we peer...

I would like to start by emphasizing the importance of surfaces. It is at a surface where many of our most interesting and useful phenomena occur. We live for example on the surface of a planet. It is at a surface where the catalysis of chemical reactions occur. It is essentially at a surface of...

The cause of nutrition and growth resides not in the organism as a whole but in the separate elementary parts—the cells.

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...

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...

The living cell is the most complex system of its size known to mankind. Its host of specialized molecules, many found nowhere else but within living material, are themselves already enormously complex. They execute a dance of exquisite fidelity, orchestrated with breathtaking precision. Vastly more elaborate than the most complicated ballet, the dance of life...

Our brains contain one hundred billion nerve cells (neurons). Each neuron makes links with ten thousand other neurons to form an incredible three dimensional grid. This grid therefore contains a thousand trillion connections – that’s 1,000,000,000,000,000 (a quadrillion). It’s hard to imagine this, so let’s visualise each connection as a disc that’s 1mm thick. Stack...

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 male frog, in mating season,” said Crake, “makes as much noise as it can. The females are attracted to the male frog with the biggest, deepest voice because it suggests a more powerful frog, one with superior genes. Small male frogs – it’s been documented – discover that if they position themselves in empty...

I like to define biology as the history of the earth and all its life — past, present, and future. To understand biology is to understand that all life is linked to the earth from which it came; it is to understand that the stream of life, flowing out of the dim past into the...

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.

More about the selection theory: Jerne meant that the Socratic idea of learning was a fitting analogy for ‘the logical basis of the selective theories of antibody formation’: Can the truth (the capability to synthesize an antibody) be learned? If so, it must be assumed not to pre-exist; to be learned, it must be acquired....

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

Darwin abolished special creations, contributed the Origin of Species and hitched all life together in one unbroken procession.

I furnished the body that was needed to sit in the defendant’s chair.[Explaining his role in the Scopes Monkey Trial.]

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.

Who gave the decisive deathblow to the argument from design on the basis of biological complexity? Both philosophers and biologists are divided on this point (Oppy 1996; Dawkins 1986; Sober 2008). Some have claimed that the biological design argument did not falter until Darwin provided a proper naturalistic explanation for adaptive complexity; others maintain that...

Branches or types are characterized by the plan of their structure,Classes, by the manner in which that plan is executed, as far as ways and means are concerned, Orders, by the degrees of complication of that structure, Families, by their form, as far as determined by structure, Genera, by the details of the execution in...

It seems that all eukaryotic cells either have, or once had (and then lost) mitochondria. In other words, possession of mitochondria is a sine qua non of the eukaryotic condition

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

Advocacy of leaf protein as a human food is based on the undisputed fact that forage crops (such as lucerne) give a greater yield of protein than other types of crops. Even with conventional food crops there is more protein in the leafy parts than in the seeds or tubs that are usually harvested.

I thought the fart was a human thing. It’s something to do with like, arse cheeks, or whatever.

…if an organised body is not in the situation and circumstances best adapted to its sustenance and propagation, then, in conceiving an indefinite variety among the individuals of that species, we must be assured, that, on the one hand, those which depart most from the best adapted constitution, will be the most liable to perish,...

Throughout history we humans have struggled to find meaning in the awesome contradiction of our human condition. Neither philosophy, nor psychology nor biology has, until now, been able to provide the truthful explanation.

Evolution is an integration of matter and concomitant dissipation of motion during which the matter passes from an indefinite incoherent homogeneity to a definite coherent heterogeneity, and during which the retained motion undergoes a parallel transformation.

Black magic, the magic of the primeval chaos, blots out or transmogrifies the true form of things. At the stroke of twelve the princess must flee the banquet or risk discovery in the rags of a kitchen wench; coach reverts to pumpkin. Instability lies at the heart of the world. With uncanny foresight folklore has...

Averages might mean something to bureaucrats and engineers, but the sea had no struck with statistics: it was a succession of unpredictable circumstances and extremes.

Life for me is just a result of experiments being performed by far more developed creatures.

If we wish to know about a man, we ask ‘what is his story–his real, inmost story?’–for each of us is a biography, a story. Each of us is a singular narrative, which is constructed, continually, unconsciously, by, through, and in us–through our perceptions, our feelings, our thoughts, our actions; and, not least, our discourse,...

If Darwinists are opposed to mentioning scientific problems with their view, you would think they would be even more opposed to mentioning intelligent design. Yet Darwinists have been discussing ID in public school science classes for years… Biology textbooks have been mentioning intelligent design since the late 1990s—but only to misrepresent and disparage it.

Things that look like they were designed, probably were… If intelligence is an operative component of the universe, a science that methodologically excludes its existence will be susceptible to being trapped in an endless chase for materialistic causes that do not exist… Where there are sufficient grounds for inferring intelligent causation, based on evidence of...
