Proteins are the machinery of living tissue that builds the structures and carries out the chemical reactions necessary for life.

In order to say that some function is understood, every relevant step in the process must be elucidated.

Biology has progressed tremendously due to the model that Darwin put forth. But the black boxes Darwin accepted are now being opened, and our view of the world is again being shaken.

Skin is made in large measure of a protein called collagen.

This fact immediately suggested a singular event - that at some time in the distant past the universe began expanding from an extremely small size. To many people this inference was loaded with overtones of a supernatural event - the creation, the beginning of the universe.

The point here is that physics followed the data where it seemed to lead, even though some thought the model gave aid and comfort to religion.

In many biological structures proteins are simply components of larger molecular machines.

A man from a primitive culture who sees an automobile might guess that it was powered by the wind or by an antelope hidden under the car, but when he opens up the hood and sees the engine he immediately realizes that it was designed.

The basic structure of proteins is quite simple: they are formed by hooking together in a chain discrete subunits called amino acids.

It is often said that science must avoid any conclusions which smack of the supernatural.

But sequence comparisons simply can't account for the development of complex biochemical systems any more than Darwin's comparison of simple and complex eyes told him how vision worked.

In Darwin's time all of biology was a black box: not only the cell, or the eye, or digestion, or immunity, but every biological structure and function because, ultimately, no one could explain how biological processes occurred.

The question of how the eye works - that is, what happens when a photon of light first impinges on the retina - simply could not be answered at that time.

The theory of undirected evolution is already dead, but the work of science continues.

Science is not a game in which arbitrary rules are used to decide what explanations are to be permitted.

It was only about sixty years ago that the expansion of the universe was first observed.

We are not inferring design to account for a black box, but to account for an open box.

Thus it seemed to Haeckel that such simple life could easily be produced from inanimate material.

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.

Although Darwin was able to persuade much of the world that a modern eye could be produced gradually from a much simpler structure, he did not even attempt to explain how the simple light sensitive spot that was his starting point actually worked.

Throughout history there have been many other examples, similar to that of Haeckel, Huxley and the cell, where a key piece of a particular scientific puzzle was beyond the understanding of the age.

It was a shock to people of the nineteenth century when they discovered, from observations science had made, that many features of the biological world could be ascribed to the elegant principle of natural selection.

Since natural selection requires a function to select, an irreducibly complex biological system, if there is such a thing, would have to arise as an integrated unit for natural selection to have anything to act on.

Proteins are the machinery of living tissue that builds the structures and carries out the chemical reactions necessary for life.

It is a shock to us in the twentieth century to discover, from observations science has made, that the fundamental mechanisms of life cannot be ascribed to natural selection, and therefore were designed. But we must deal with our shock as best we can and go on.

In the 19th century the anatomy of the eye was known in great detail and the sophisticated mechanisms it employs to deliver an accurate picture of the outside world astounded everyone who was familiar with them.

As can be seen even by this limited number of examples proteins carry out amazingly diverse functions.

The conclusion of design flows naturally from the data we should not shrink from it we should embrace it and build on it.

Roosevelt's magic lay in one facet of his personality: He knew how to take the risk. No other man in public life I knew could so readily take the challenge of the new.

Focusing your life solely on making a buck shows a certain poverty of ambition. It asks too little of yourself. Because it's only when you hitch your wagon to something larger than yourself that you realize your true potential.

Art teaches nothing, except the significance of life.

If it came to saving the life of one priest or sacrificing the life of an entire congregation, the church would save the life of the priest. Which is backwards, of course.

Work is the meat of life, pleasure the dessert.

All literary men are Red Sox fans - to be a Yankee fan in a literate society is to endanger your life.

At the end, the realization is that she had to get to a place in her life where she could drop her guard and make peace with the fact that whether she had a small amount of time, that she had to kind of live it completely through, instead of living by the rules.

You have choices to make about what you do with the rest of your life.

From the standpoint of observation, then, we must regard it as a highly probable hypothesis that the beginnings of the mental life date from as far back as the beginnings of life at large.

I want to have babies one day but not right now. When I do it I want to do it really well. I want it to be my best project in life.

Any judge who allows an adulterer with a live-in girlfriend to terminate the life of his wife should be impeached.

I can assure you, public service is a stimulating, proud and lively enterprise. It is not just a way of life, it is a way to live fully.

The work which is manipulated looks a little boring to me. I think life is pretty strange anyway. It is wooo, wooo, wooo!

With an eye made quiet by the power of harmony, and the deep power of joy, we see into the life of things.

This isn't life in the fast lane, it's life in the oncoming traffic.

The good parts of a book may be only something a writer is lucky enough to overhear or it may be the wreck of his whole damn life and one is as good as the other.

Sometimes life's so much cooler when you just don't know any better and all the painful lessons have not hammered your head open yet.

My life is so full of surprises, nothing surprises me any more.

I love children and I love men, but I can't commit to either for the rest of my life.

Pop music, disco music, and heavy metal music is about shutting out the tensions of life, putting it away.

Yes, I am Algerian of Moroccan origin through my parents, but all my life is Algeria. I was born there.
