All the more recent work on alkaptonuria has… strengthened the belief that the homogentisic acid excreted is derived from tyrosine, but why alkaptonuric individuals pass the benzene ring of their tyrosine unbroken and how and...

I think it’s reasonable to suppose that one could oscillate between being biologically 20 and biologically 25 indefinitely.

It necessarily follows that chance alone is at the source of every innovation, and of all creation in the biosphere. Pure chance, absolutely free but blind, at the very root of the stupendous edifice of...

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

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...

Information and complexity go hand in hand.

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.

To grasp the reality of life as it has been revealed by molecular biology, we must magnify a cell a thousand million times until it is twenty kilometers in diameter and resembles a giant airship...

Evolution is more about adaptivity than adaptability.

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...

The life sciences contain spiritual values which can never be explained by the materialistic attitude of present day science

For these two years I have been gravitating towards your doctrines, and since the publication of your primula paper with accelerated velocity. By about this time next year I expect to have shot past you,...

What was up with class today? It was watered-down porn. He practically had you and Patch on top of your lab table, horizontal, minus your clothes, doing the Big Deed.

But just in proportion as this process of extermination has acted on an enormous scale, so must the number of intermediate varieties, which have formerly existed, be truly enormous. Why then is not every geological...

Men write more books. Men give more lectures. Men ask more questions after lectures. Men post more e-mail to Internet discussion groups. To say this is due to patriarchy is to beg the question of...

Evolution, thus, is merely contingent on certain processes articulated by Darwin: variation and selection. No longer is a fixed object transformed, as in transformational evolution, but an entirely new start is, so to speak, made...

I know sex sells. I also know gametes are sex cells. Her and I had chemistry together, and that’s just biology.

When General Genius built the first mentar [Artificial Intelligence] mind in the last half of the twenty-first century, it based its design on the only proven conscious material then known, namely, our brains. Specifically, the...

The ancestors of the higher animals must be regarded as one-celled beings, similar to the Amoebae which at the present day occur in our rivers, pools, and lakes. The incontrovertible fact that each human individual...

Originally, the atoms of carbon from which we’re made were floating in the air, part of a carbon dioxide molecule. The only way to recruit these carbon atoms for the molecules necessary to support life—the...

in human males, testosterone appears to promote behavior intended to dominate other people. This behavior can be expressed aggressively, even violently, as well as nonaggressively. Testosterone levels, even a single baseline measurement, correlate well with...

To establish evolutionary interrelatedness invariably requires exhibiting similarities between organisms. Within Darwinism, there’s only one way to connect such similarities, and that’s through descent with modification driven by the Darwinian mechanism. But within a design-theoretic...

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...

We wish to discuss a structure for the salt of deoxyribose nucleic acid. (D.N.A.). This structure has novel features which are of considerable biologic interest.

This view, as a rounded whole and in all its essential elements, has very recently disappeared from science. It died a royal death with Agassiz.[It had formerly been held that there were no genetic connections...

Not only in antiquity but in our own times also laws have been passed…to secure good conditions for workers; so it is right that the art of medicine should contribute its portion for the benefit...

Humanity is a biological species, living in a biological environment, because like all species, we are exquisitely adapted in everything: from our behavior, to our genetics, to our physiology, to that particular environment in which...

If these d’Herelle bodies were really genes, fundamentally like our chromosome genes, they would give us an utterly new angle from which to attack the gene problem. They are filterable, to some extent isolable, can...

… on these expanded membranes [butterfly wings] Nature writes, as on a tablet, the story of the modifications of species, so truly do all changes of the organisation register themselves thereon. Moreover, the same colour-patterns...

First LawIn every animal which has not passed the limit of its development, a more frequent and continuous use of any organ gradually strengthens, develops and enlarges that organ, and gives it a power proportional...

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...

Animals have genes for altruism, and those genes have been selected in the evolution of many creatures because of the advantage they confer for the continuing survival of the species.

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...

George Gey paid his way through a biology degree at the University of Pittsburgh by working as a carpenter and mason, and he could make nearly anything for cheap or free. During his second year...

People, as curious primates, dote on concrete objects that can be seen and fondled. God dwells among the details, not in the realm of pure generality. We must tackle and grasp the larger, encompassing themes...

This little book has been written in the hope that it may appeal to several classes of readers.Not infrequently I have been asked by friends of different callings in life to recommend them some book...

There are a lot of things animals do that we can’t,” she says, “like flying and camouflage, and we’ve adapted, through technology … It’s funny when people say something is natural, or not. Compared with...

Evidently neither cats nor dogs, nor other animals that listen to human music, were constituted for the appreciation of it, for it is not of the slightest use to them in the struggle for existence....

The fundamental biological variant is DNA. That is why Mendel’s definition of the gene as the unvarying bearer of hereditary traits, its chemical identification by Avery (confirmed by Hershey), and the elucidation by Watson and...

Threats to our standing in the eyes of others are remarkably potent biologically, almost as powerful as those to our very survival.

Men and women fall in love abandoning reality in favour of the dream

There are species that retain their characteristics even in conditions that are relatively different from their natural ones; other species in similar circumstances instead become extinct; otherwise what takes place is racial mixing with other...

The controversy between Darwinism and intelligent design has the characteristics of major scientific revolutions in the past. Darwinists are losing power because they treat with contempt the very people on whom they depend the most:...

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,...

The curious fact is that biology tells us nothing about desire. And, when you think about it, culture — novels, movies, opera, and quite a lot of painting — is about desire, how we manage...

A biochemist colleague has kindly provided me with a bottle of hydrogen peroxide, and enough hydroquinone for 50 bombardier beetles, I am now about to mix the two together. According to the above, they will...

That enormously complex biological interactions are so flawlessly coordinated as to result in such obvious manifestations as human thought or the electrical activity that dries the heartbeat is as exciting to me — actually more...

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

Some believe what separates men from animals is our ability to reason. Others say it’s language or romantic love, or opposable thumbs. Living here in this lost world, I’ve come to believe it is more...

If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down. But I can find no such case.
