Prebiotic Chemistry Quotes

It is emphatically the case that life could not arise spontaneously in a primeval soup of any kind.... Furthermore, no geological evidence indicates an organic soup ever existed on this planet. We may therefore with fairness call this scenario the myth of the pre-biotic soup.

The origin of life is one of the great outstanding mysteries of science.

Life cannot have had a random beginning. ... The trouble is that there are about two thousand enzymes, and the chance of obtaining them all in a random trial is only one part in 10 to the 40,000 power, an outrageously small probability that could not be faced even if the whole universe consisted of organic soup.

The important point is that since the origin of life belongs in the category of at-least-once phenomena, time is on its side. However improbable we regard this event, or any of the steps which it involves, given enough time it will almost certainly happen at least once. And for life as we know it, with its capacity for growth and reproduction, once may be enough.

Scientists are still trying to produce life in the laboratory, but it shouldn't be difficult if the laboratory assistant is pretty and willing.

One has only to contemplate the magnitude of this task to concede that the spontaneous generation of a living organism is impossible. Yet here we are-as a result, I believe, of spontaneous generation.

The physical fabric of the world had to be such as to enable that ten billion year preliminary evolution to produce the raw materials of life. Without it there would not have been the chemical materials to allow life to evolve here on earth.

Most research into life's murky origin has been carried out by chemists. They've tried a variety of approaches in their attempts to recreate the first steps on the road to life, but little progress has been made. Perhaps that is no surprise, given life's stupendous complexity.

In my lab, we're interested in the transition from chemistry to early biology on the early earth.

Although a biologist, I must confess I do not understand how life came about... I consider that life only starts at the level of a functional cell. The most primitive cells may require at least several hundred different specific biological macro-molecules. How such already quite complex structures may have come together, remains a mystery to me. The possibility of the existence of a Creator, of God, represents to me a satisfactory solution to this problem.

All of us who study the origin of life find that the more we look into it, the more we feel it is too complex to have evolved anywhere. We all believe as an article of faith that life evolved from dead matter on this planet. It is just that life's complexity is so great, it is hard for us to imagine that it did.

Scientists have no agreed theory of the origin of life - plenty of scenarios, conjectures and just-so stories, but nothing with solid experimental support.

The notion that not only the biopolymer but the operating program of a living cell could be arrived at by chance in a primordial organic soup here on the Earth is evidently nonsense of a high order.

Life began three and a half billion years ago, necessarily about as simple as it could be, because life arose spontaneously from the organic compounds in the primeval oceans.

We know too little about how life began on Earth to lay confident odds. It may have involved a fluke so rare that it happened only once in the entire galaxy. On the other hand, it may have been almost inevitable, given the right environment.

But when I talk to people who are Darwinists or evolutionists and say, 'Well, how did life begin' - they're... they don't have an answer. I mean, they have an answer, but it's a BS answer. It's an answer that wouldn't make sense to a small child.

From a personal perspective, I am disappointed that we have yet to really achieve a full understanding of the origins of life on Earth. What was the spark that, billions of years ago, kickstarted the process of evolution that has brought us life as we know it today? I hope that we will get some answers to that in my lifetime.

For decades, we've been trying to cook up the building blocks of life, in the lab, and recreate the origins of it all, but the parts didn't seem to fit together, until now.

So how can we test the idea that the transition from nonlife to life is simple enough to happen repeatedly? The most obvious and straightforward way is to search for a second form of life on Earth. No planet is more Earth-like than Earth itself, so if the path to life is easy, then life should have started up many times over right here.

It is, I believe, justifiable to make the generalization that anything an organic chemist can synthesize can be made without him. All he does is increase the probability that given reactions will 'go.' So it is quite reasonable to assume that given sufficient time and proper conditions, nucleotides, amino acids, proteins, and nucleic acids will arise by reactions that, though less probable, are as inevitable as those by which the organic chemist fulfills his predictions. So why not self-duplicating virus-like systems capable of further evolution?

The question of the origin of life is essentially speculative. We have to construct, by straightforward thinking on the basis of very few factual observations, a plausible and self-consistent picture of a process which must have occurred before any of the forms which are known to us in the fossil record could have existed.

Many investigators feel uneasy stating in public that the origin of life is a mystery, even though behind closed doors they admit they are baffled.

Prebiotic chemistry on other worlds is going to be common. Plenty of small rocky planets will have similar chemistry. It's almost a given.

One of the most significant events in our distant past is still perhaps the greatest mystery: the origins of life itself.

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