Check out this column on the origin of life from the radically leftist UK Guardian, written by agnostic cosmologist Paul Davies. (The same Paul Davies who is occasionally quoted by William Lane Craig)
Excerpt:
The origin of life is one of the great outstanding mysteries of science. How did a non-living mixture of molecules transform themselves into a living organism? What sort of mechanism might be responsible?
[…]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. Even the simplest bacterium is incomparably more complicated than any chemical brew ever studied.
But a more fundamental obstacle stands in the way of attempts to cook up life in the chemistry lab. The language of chemistry simply does not mesh with that of biology. Chemistry is about substances and how they react, whereas biology appeals to concepts such as information and organisation. Informational narratives permeate biology. DNA is described as a genetic “database”, containing “instructions” on how to build an organism. The genetic “code” has to be “transcribed” and “translated” before it can act. And so on. If we cast the problem of life’s origin in computer jargon, attempts at chemical synthesis focus exclusively on the hardware – the chemical substrate of life – but ignore the software – the informational aspect. To explain how life began we need to understand how its unique management of information came about.
[…]Sara Walker, a Nasa astrobiologist working at Arizona State University, and I have proposed that the significant property of biological information is not its complexity, great though that may be, but the way it is organised hierarchically. In all physical systems there is a flow of information from the bottom upwards, in the sense that the components of a system serve to determine how the system as a whole behaves. Thus if a meteorologist wants to predict the weather, he may start with local information, such as temperature and air pressure, taken at various locations, and calculate how the weather system as a whole will move and change. In living organisms, this pattern of bottom-up information flow mingles with the inverse – top-down information flow – so that what happens at the local level can depend on the global environment, as well as vice versa.
[…]The way life manages information involves a logical structure that differs fundamentally from mere complex chemistry. Therefore chemistry alone will not explain life’s origin, any more than a study of silicon, copper and plastic will explain how a computer can execute a program. Our work suggests that the answer will come from taking information seriously as a physical agency, with its own dynamics and causal relationships existing alongside those of the matter that embodies it – and that life’s origin can ultimately be explained by importing the language and concepts of biology into physics and chemistry, rather than the other way round.
The point of me posting this is simple. The thing to be explained in the origin of life is not a cake, where you can jumble ingredients together and get something. The thing to be explained is information. The origin of life is a programming problem, not a cooking problem. Where did the software come from – the first basic program that allowed for the basic functions of life, like self-replication.
Dr. Davies is hoping for a naturalistic solution to the problem, because he is a naturalist. But at least he is clear about specifying the thing that needs to be explained. A lot more clear than the journalists who explain intelligent design as the belief that some things are too complex to have evolved. But that’s wrong. The real question is: where did the information come from?
My two favorite economists are Walter Williams and Thomas Sowell. Both are conservative or libertarian. Both of them happen to be black. But neither is especially outspoken about religion. But imagine my surprise when I read this CNS News column on gun violence in schools by Walter Williams, who I always thought was the more libertarian of the two.
Look:
When I attended primary and secondary school — during the 1940s and ’50s — one didn’t hear of the kind of shooting mayhem that’s become routine today. Why? It surely wasn’t because of strict firearm laws. My replica of the 1902 Sears mail-order catalog shows 35 pages of firearm advertisements. People just sent in their money, and a firearm was shipped.
Dr. John Lott, author of “More Guns, Less Crime,” reports that until the 1960s, some New York City public high schools had shooting clubs where students competed in citywide shooting contests for university scholarships. They carried their rifles to school on the subways and, upon arrival, turned them over to their homeroom teacher or the gym coach and retrieved their rifles after school for target practice. Virginia’s rural areas had a long tradition of high-school students going hunting in the morning before school and sometimes storing their rifles in the trunks of their cars that were parked on school grounds. Often a youngster’s 12th or 14th birthday present was a shiny new .22-caliber rifle, given to him by his father.
Fathers? Children don’t grow up with fathers any more, 42% of the time. And why not? The feminists told us that men are evil, and that marriage is sexist. And the socialists told us that rewarding single motherhood was a good idea, because it makes women who don’t bother to get married before having sex more equal to those who do bother to get married first. But fatherlessness is a huge factor in criminal behavior, as I showed before.
Dr. Williams continues:
What explains today’s behavior versus yesteryear’s? For well over a half-century, the nation’s liberals and progressives — along with the education establishment, pseudo-intellectuals and the courts — have waged war on traditions, customs and moral values. These people taught their vision, that there are no moral absolutes, to our young people. To them, what’s moral or immoral is a matter of convenience, personal opinion or a consensus.
During the ’50s and ’60s, the education establishment launched its agenda to undermine lessons children learned from their parents and the church with fads such as “values clarification.” So-called sex education classes are simply indoctrination that sought to undermine family and church strictures against premarital sex.
Lessons of abstinence were ridiculed and considered passé and replaced with lessons about condoms, birth control pills and abortions. Further undermining of parental authority came with legal and extralegal measures to assist teenage abortions with neither parental knowledge nor consent.
Customs, traditions, moral values and rules of etiquette, not laws and government regulations, are what make for a civilized society. These behavioral norms — transmitted by example, word of mouth and religious teachings — represent a body of wisdom distilled through ages of experience, trial and error, and looking at what works.
The importance of customs, traditions and moral values as a means of regulating behavior is that people behave themselves even if nobody’s watching. Police and laws can never replace these restraints on personal conduct so as to produce a civilized society. At best, the police and criminal justice system are the last desperate line of defense for a civilized society. The more uncivilized we become the more laws that are needed to regulate behavior.
Many customs, traditions and moral values have been discarded without an appreciation for the role they played in creating a civilized society, and now we’re paying the price. What’s worse is that instead of a return to what worked, people want to replace what worked with what sounds good, such as zero-tolerance policies in which bringing a water pistol, drawing a picture of a pistol, or pointing a finger and shouting “bang-bang” produces a school suspension or arrest.
See, now that’s a smart libertarian. Smart libertarians understand that liberty depends on people being aware of the design of the universe, and the objective moral obligations imposed by that design. If we don’t promote institutions and people that help us to explore the design of the universe, then we are going to have to rely on big government to regulate us instead of regulating ourselves. What we’ve done instead is make impossible to speak about the reality of God and the reality of objective morality in schools, or in any other public place, for that matter. Hearing about God and morality is just too offensive to people who want to put their own selfishness above the moral law.
Similarly, libertarians should not be pushing for promiscuity, abortion and same-sex marriage, either. Intact families are necessary for raising the next generation of citizens to be well-adjusted, law-abiding and productive. Marriages are more stable when the participants are chaste and/or abstinent for a period of time early in the relationship. And children do better when raised by a mother and a father, and less well in other arrangements. Either we feel an obligation to control our own desires and make a plan for marriage success, so that we can provide children with a stable nurturing environment, or the government will have to control the anti-social behavior of fatherless children.

He is President elect of the ASA and will serve his term in 2008.
Below, I analyze a lecture entitled “Is There Scientific Evidence for an Intelligent Designer?”. Dr. Bradley explains how the progress of science has made the idea of a Creator and Designer of the universe more acceptable than ever before.
1. The correspondence of natural phenomena to mathematical law
All observations of physical phenomena in the universe, such as throwing a ball up in the air, are described by a few simple, elegant mathematical equations.
2. The fine-tuning of physical constants and rations between constants in order to provide a life-permitting universe
Life has certain minimal requirements; long-term stable source of energy, a large number of different chemical elements, an element that can serve as a hub for joining together other elements into compounds, etc.
In order to meet these minimal requirements, the physical constants, (such as the gravitational constant), and the ratios between physical constants, need to be withing a narrow range of values in order to support the minimal requirements for life of any kind.
Slight changes to any of the physical constants, or to the rations between the constants, will result in a universe inhospitable to life.
The range of possible ranges over 70 orders of magnitude.
Although each individual selection of constants and ratios is as unlikely as any other selection, the vast majority of these possibilities do not support the minimal requirements of life of any kind. (In the same way as any hand of 5 cards that is dealt is as likely as any other, but you are overwhelmingly likely NOT to get a royal flush. In our case, a royal flush is a life-permitting universe).
Examples of finely-tuned constants and ratios: (there are more examples in the lecture)
a) The strong force: (the force that binds nucleons (= protons and neutrons) together in nucleus, by means of meson exchange)
if the strong force constant were 2% stronger, there would be no stable hydrogen, no long-lived stars, no hydrogen containing compounds. This is because the single proton in hydrogen would want to stick to something else so badly that there would be no hydrogen left!
if the strong force constant were 5% weaker, there would be no stable stars, few (if any) elements besides hydrogen. This is because you would be able to build up the nuclei of the heavier elements, which contain more than 1 proton.
So, whether you adjust the strong force up or down, you lose stars than can serve as long-term sources of stable energy, or you lose chemical diversity, which is necessary to make beings that can perform the minimal requirements of living beings. (see below)
b) The conversion of beryllium to carbon, and carbon to oxygen
Life requires carbon in order to serve as the hub for complex molecules, but it also requires oxygen in order to create water.
Carbon is like the hub wheel in a tinker toy set: you can bind other elements together to more complicated molecules (e.g. – “carbon-based life), but the bonds are not so tight that they can’t be broken down again later to make something else.
The carbon resonance level is determined by two constants: the strong force and electromagnetic force.
If you mess with these forces even slightly, you either lose the carbon or the oxygen.
3. Fine-tuning to allow a habitable planet
A number of factors must be fine-tuned in order to have a planet that supports life
Initial estimates predicted abundant life in the universe, but revised estimates now predict that life is almost certainly unique in the galaxy, and probably unique in the universe.
Even though there are lots of stars in the universe, the odds are against any of them supporting complex life.
Here are just a few of the minimal requirements for habitability: must be a single star solar system, in order to support stable planetary orbits, the planet must be the right distance from the sun in order to have liquid water at the surface, the planet must sufficient mass in order to retain an atmosphere, etc.
The best non-theistic response to this argument is to postulate a multiverse, but that is very speculative and there is no experimental evidence that supports it.
Evidence #2: The origin of the universe
1. The progress of science has shown that the entire physical universe came into being out of nothing (= “the big bang”). It also shows that the cause of this creation event is non-physical and non-temporal. The cause is supernatural.
Atheism prefers an eternal universe, to get around the problem of a Creator having to create the universe.
Discovery #1: Observations of galaxies moving away from one another confirms that the universe expanded from a single point.
Discovery #2: Measurements of the cosmic background radiation confirms that the universe exploding into being.
Discovery #3: Predictions of elemental abundances prove that the universe is not eternal.
Discovery #4:The atheism-friendly steady-state model and oscillating model were both falsified by the evidence.
And there were other discoveries as well, mentioned in the lecture.
The best non-theistic response to this argument is to postulate a hyper-universe outside of ours, but that is very speculative and there is no experimental evidence that supports it.
Evidence #3: The origin of life
1. The progress of science has shown that the simplest living organism contains huge amounts of biological information, similar to the Java code I write all day at work. This is a problem for atheists, because the sequence of instructions in a living system has to come together all at once, it cannot have evolved by mutation and selection – because there was no replication in place prior to the formation of that first living system!
Living systems must support certain minimum life functions: processing energy, storing information, and replicating.
There needs to be a certain amount of complexity in the living system that can perform these minimum functions.
But on atheism, the living system needs to be simple enough to form by accident in a pre-biotic soup, and in a reasonable amount of time.
The minimal functionality in a living system is a achieved by DNA, RNA and enzymes. DNA and RNA are composed of sequences of proteins, which are in turn composed of sequences of amino acids.
Consider the problems of building a chain of 100 amino acids
The amino acids must be left-handed only, but left and right kinds are equally abundant in nature. How do you sort out the right-handed ones?
The amino acids must be bound together using peptide bonds. How do you prevent other types of bonds?
Each link of the amino acid chain needs to be carefully chosen such that the completed chain with fold up into a protein. How do you choose the correct amino acid for each link from the pool of 20 different kinds found in living systems?
In every case, a human or other intelligence could solve these problems by doing what intelligent agents do best: making choices.
But who is there to make the choices on atheism?
The best current non-theistic response to this is to speculate that aliens may have seeded the Earth with life at some point in the past.
The problem of the origin of life is not a problem of chemistry, it is a problem of engineering. Every part of car functionality can be understood and described using the laws of physics and chemistry. But an intelligence is still needed in order to assemble the components into a system that has the minimal requirements for a functioning vehicle.
