Could the building blocks of life have emerged spontaneously on the early Earth?

The origin of life

There are two problems related to the origin of the first living cell, on atheism:

  1. The problem of getting the building blocks needed to create life – i.e. the amino acids
  2. The problem of creating the functional sequences of amino acids and proteins that can support the minimal operations of a simple living cell

Normally, I concede the first problem and grant the atheist all the building blocks he needs. This is because step 2 is impossible. There is no way, on atheism, to form the sequences of amino acids that will fold up into proteins, and then to form the sequences of proteins that can be used to form everything else in the cell, including the DNA itself. But that’s tomorrow’s topic.

Today, let’s take a look at the problems with step 1.

The problem of getting the building blocks of life

Now you may have heard that some scientists managed to spark some gasses to generate most of the 20 amino acids found in living systems. These experiments are called the “Miller-Urey” experiments.

The IDEA center has a nice summary of origin-of-life research that explains a few of the main problems with step 1.

Miler and Urey used the wrong gasses:

Miller’s experiment requires a reducing methane and ammonia atmosphere,11, 12 however geochemical evidence says the atmosphere was hydrogen, water, and carbon dioxide (non-reducing).15, 16 The only amino acid produced in a such an atmosphere is glycine (and only when the hydrogen content is unreasonably high), and could not form the necessary building blocks of life.11

Miller and Urey didn’t account for UV of molecular instability:

Not only would UV radiation destroy any molecules that were made, but their own short lifespans would also greatly limit their numbers. For example, at 100ºC (boiling point of water), the half lives of the nucleic acids Adenine and Guanine are 1 year, uracil is 12 years, and cytozine is 19 days20 (nucleic acids and other important proteins such as chlorophyll and hemoglobin have never been synthesized in origin-of-life type experiments19).

Miller and Urey didn’t account for molecular oxygen:

We all have know ozone in the upper atmosphere protects life from harmful UV radiation. However, ozone is composed of oxygen which is the very gas that Stanley Miller-type experiments avoided, for it prevents the synthesis of organic molecules like the ones obtained from the experiments! Pre-biotic synthesis is in a “damned if you do, damned if you don’t” scenario. The chemistry does not work if there is oxygen because the atmosphere would be non-reducing, but if there is no UV-light-blocking oxygen (i.e. ozone – O3) in the atmosphere, the amino acids would be quickly destroyed by extremely high amounts of UV light (which would have been 100 times stronger than today on the early earth).20, 21, 22 This radiation could destroy methane within a few tens of years,23 and atmospheric ammonia within 30,000 years.15

And there were three other problems too:

At best the processes would likely create a dilute “thin soup,”24 destroyed by meteorite impacts every 10 million years.20, 25 This severely limits the time available to create pre-biotic chemicals and allow for the OOL.

Chemically speaking, life uses only “left-handed” (“L”) amino acids and “right-handed” (“R)” genetic molecules. This is called “chirality,” and any account of the origin of life must somehow explain the origin of chirality. Nearly all chemical reactions produce “racemic” mixtures–mixtures with products that are 50% L and 50% R.

Two more problems are not mentioned in the article. A non-peptide bond anywhere in the chain will ruin the chain. You need around 200 amino acids to make a protein. If any of the bonds is not a peptide bond, the chain will not work in a living system. Additionally, the article does not mention the need for the experimenter to intervene in order to prevent interfering cross-reactions that would prevent the amino acids from forming.

The progress of science

As science has progressed, the discoveries have proved out the need for a Creator and Designer in every area – the big bang, cosmic, galactic and stellar fine-tuning, the Cambrian explosion, etc…. and even the origin of life.

“More than 30 years of experimentation on the origin of life in the fields of chemical and molecular evolution have led to a better perception of the immensity of the problem of the origin of life on Earth rather than to its solution. At present all discussions on principal theories and experiments in the field either end in stalemate or in a confession of ignorance. New lines of thinking and experimentation must be tried.”

(Dose, Klaus, “The Origin of Life: More Questions Than Answers,” Interdisciplinary Science Reviews, Vol. 13, No. 4, 1988, p.348.)

Meanwhile, atheists are left to have blind faith that the progress scientists have made during decades of research will be miraculously overturned by new evidence that their beloved unobservable Flying Spaghetti Monster, (peas be upon him), did it. Hey! Don’t blaspheme against the non-supernatural powers of his noodly appendage! (Two Ph.Ds in biology will not save you from the wrath of the Darwoid cultists!)

To see how bad this gets for atheists, watch this video where Dawkins says that unobservable aliens evolved somewhere else and then seeded the Earth with life. He has no evidence that these aliens did evolve (no fossil record), and even worse, he does not know whether they even exist. Nevertheless, that is the state of atheism today – an unobservable Flying Spaghetti Monster evolved somewhere else and seeded the Earth with life.

What else could have happened?

One of my favorite resources on the origin of life is this interview from the University of California with former atheist and origin of life researcher Dean Kenyon. Kenyon, a professor of Biology at San Francisco State University, wrote the textbook on “chemical evolution”, which is the view that chemicals can arrange themselves in order to create the first living cell, without intervention.

This interview from the University of California with another origin of life researcher, Charles Thaxton, is also one of my favorites.

You’ll need Quicktime to see the videos, or buy the videos from ARN. (Kenyon, Thaxton) I have both of them – they rock!

Commentary

Should Obama pick judges who favor Democrat special interest groups?

2 Comments

Yes, I know he calls it “empathy”. And by empathy he means twisting the law to benefit the people who voted for him. What you don’t believe me? Well, check out the evidence here about who Obama’s bailouts really benefit. Nice Deb even links to a story that questions whether the recent Chrysler dealership closures were made because the owners donated to Republican candidates.

Now, what kind of judges does someone like Obama need to install in order to back his authoritarian regime? Well, it has to be someone who will help him to punish the people who disagree with him. Someone who believes that there are good Americans (Democrats) and bad Americans (Republicans), and that the laws should apply differently to those different groups.

Let’s take a look at what my favorite two economists, Thomas Sowell and Walter Williams have to say about this.

Thomas Sowell

Thomas Sowell has a four-part series on Obama’s judicial philosophy.

In part one, Sowell asks what it means that Obama will pick judges who come from certain groups, and who believe in twisting the law to favor those groups.

That President Obama has made “empathy” with certain groups one of his criteria for choosing a Supreme Court nominee is a dangerous sign of how much further the Supreme Court may be pushed away from the rule of law and toward even more arbitrary judicial edicts to advance the agenda of the left and set it in legal concrete, immune from the democratic process.

Would you want to go into court to appear before a judge with “empathy” for groups A, B and C, if you were a member of groups X, Y or Z? Nothing could be further from the rule of law. That would be bad news, even in a traffic court, much less in a court that has the last word on your rights under the Constitution of the United States.

Appoint enough Supreme Court justices with “empathy” for particular groups and you would have, for all practical purposes, repealed the 14th Amendment, which guarantees “equal protection of the laws” for all Americans.

In part two, Sowell talks about Olive Wendell Holmes’ strict constructionist jurisprudence, which allowed citizens to undertake economic enterprises because they could predict how the law would be enforced.

Justice Holmes saw his job to be “to see that the game is played according to the rules whether I like them or not.”

That was because the law existed for the citizens, not for lawyers or judges, and the citizen had to know what the rules were, in order to obey them.

He said: “Men should know the rules by which the game is played. Doubt as to the value of some of those rules is no sufficient reason why they should not be followed by the courts.”

Legislators existed to change the law.

In part three, Sowell talks about why the judiciary must remain impartial as a check on the power of the legislative and executive branches.

Barack Obama’s vision of America is one in which a President of the United States can fire the head of General Motors, tell banks how to bank, control the medical system and take charge of all sorts of other activities for which neither he nor other politicians have any expertise or experience.The Constitution of the United States gives no president, nor the entire federal government, the authority to do such things. But spending trillions of dollars to bail out all sorts of companies buys the power to tell them how to operate.

Appointing judges to the federal courts– including the Supreme Court– who believe in expanding the powers of the federal government to make arbitrary decisions, choosing who will be winners and losers in the economy and in the society, is perfectly consistent with a vision of the world where self-confident and self-righteous elites rule according to their own notions, instead of merely governing under the restraints of the Constitution.

In part four, Sowell explains how big government socialists like Obama view the Constitution as an obstacle to be overcome.

Judicial expansion of federal power is not really new, even if the audacity with which that goal is being pursued may be unique. For more than a century, believers in bigger government have also been believers in having judges “interpret” the restraints of the Constitution out of existence.

They called this “a living Constitution.” But it has in fact been a dying Constitution, as its restraining provisions have been interpreted to mean less and less, so that the federal government can do more and more.

For example, the Constitution allows private property to be taken for “public use”– perhaps building a reservoir or a highway — if “just compensation” was paid. But that power was expanded by the Supreme Court in 2005 when it “interpreted” this to mean that private property could be taken for a “public purpose,” which could include almost anything for which politicians could come up with the right rhetoric.

Walter Williams

And Walter Williams writes about the dangers of empathy using last year’s Super Bowl as an example.

The Pittsburgh Steelers have won six Super Bowl titles, seven AFC championships and hosted 10 conference games. No other AFC or NFC team can match this record. By contrast, the Arizona Cardinals’ last championship victory was in 1947 when they were based in Chicago. In anyone’s book, this is a gross disparity. Should the referees have the empathy to understand what it’s like to be a perennial loser and what would you think of a referee whose decisions were guided by his empathy? Suppose a referee, in the name of compensatory justice, stringently applied pass interference or roughing the passer violations against the Steelers and less stringently against the Cardinals. Or, would you support a referee who refused to make offensive pass interference calls because he thought it was a silly rule? You’d probably remind him that the league makes the rules, not referees.

I’m betting that most people would agree that football justice requires that referees apply the rules blindly and independent of the records or any other characteristic of the two teams. Moreover, I believe that most people would agree that referees should evenly apply the rules of the games even if they personally disagreed with some of the rules.

But what if the Steelers had lost due to referee partiality? Well, presumably they would stop playing the game. And when enough small businesses get tired of being sued by special interest group plaintiffs, we will all be working for the government and that will be the end of our liberty.

Probably one of the greatest books ever written is Thomas Sowell’s “A Conflict of Visions”. Go out right now and buy it if you don’t have it, but be warned, it was a tough read for a software engineer like me, and my Dad also found it difficult when I gave it to him.
