Science Creates Artificial Cell and Creationists Spin, Spin, Spin

Posted by mattusmaximus on May 30, 2010

A couple of weeks back, a bombshell of an announcement hit the scientific world: the first artificial cell has been synthesized in the lab. Needless to say, this is a big deal, because it not only has vast implications for bio- & genetic engineering, but the discovery can help fill in gaps in our knowledge of how life evolved naturally from non-life (see my previous blog post on this issue – The God-of-the-Gaps Just Got Smaller: Link Found Between Life & Inorganic Matter)

What’s also interesting is the reaction from some religious & creationist circles concerning this discovery.  First, there is the response from the Catholic Church warning scientists not to “play God”…

Catholic Church officials said Friday that the recently created first synthetic cell could be a positive development if correctly used, but warned scientists that only God can create life.

Vatican and Italian church officials were mostly cautious in their first reaction to the announcement from the United States that researchers had produced a living cell containing manmade DNA. They warned scientists of the ethical responsibility of scientific progress and said that the manner in which the innovation is applied in the future will be crucial.

“It’s a great scientific discovery. Now we have to understand how it will be implemented in the future,” Monsignor Rino Fisichella, the Vatican’s top bioethics official, told Associated Press Television News.

“If we ascertain that it is for the good of all, of the environment and man in it, we’ll keep the same judgment,” he said. “If, on the other hand, the use of this discovery should turn against the dignity of and respect for human life, then our judgment would change.”

I’m all for proceeding cautiously in this particular research, because there is the potential for abuse, just as there is with any kind of new technology.  But read between the lines of what the Vatican is saying – they seem to be implying that, somehow, this artificial life is fundamentally different from “normal” life simply because of the manner in which it was created.

The God-of-the-Gaps Just Got Smaller: Link Found Between Life & Inorganic Matter

Posted by mattusmaximus on May 20, 2010

If you’re familiar with various creationist arguments, you will no doubt recognize the infamous god-of-the-gaps argument. This is basically a variation on the classic logical fallacy called the argument from ignorance, which basically states that if we don’t understand some phenomenon with 100% clarity (such as the origins of life), then that must mean that “Poof! God did it”…

There is one fatal flaw with this kind of argument, which begs an interesting theological question: what happens to the god-of-the-gaps when we do come up with evidence & naturalistic explanations for the gaps in our knowledge?  Most scholarly theologians disdain the god-of-the-gaps argument precisely to avoid this trap, because they don’t want their god somehow diminished as science marches ever forward.

But not creationists, who usually take the intellectually lazy & dishonest route by simply dismissing the evidence filling in said gaps.  Only by ignoring and distorting the science can their god-of-the-gaps be maintained, so while the rest of us learn more and more about our universe and our place within it, creationists insist upon wallowing in their ignorance, content that their twisted reading of a 2000 year-old holy text (only one of many different supposedly “divinely inspired” holy texts out there) has revealed to them the truth.

So here’s the big news, and why the god-of-the-gaps just got a lot smaller: scientists have discovered a missing link between life and inorganic matter…

Philosophers and scientists have argued about the origins of life from inorganic matter ever since Empedocles (430 B.C.) argued that every thing in the universe is made up of a combination of four eternal ‘elements’ or ‘roots of all’: earth, water, air, and fire, and that all change is explained by the arrangement and rearrangement of these four elements. Now, scientists have discovered that simple peptides can organize into bi-layer membranes. The finding suggests a “missing link” between the pre-biotic Earth’s chemical inventory and the organizational scaffolding essential to life.

“This is a boon to our understanding of large, structural assemblies of molecules,” says Emory Chemistry Chair David Lynn, who helped lead the effort, which were collaborations of the departments of chemistry, biology and physics. “We’ve proved that peptides can organize as bi-layers, and we’ve generated the first, real-time imaging of the self-assembly process. We can actually watch in real-time as these nano-machines make themselves.” …

… The research is part of “The Center for Chemical Evolution,” a center based at Emory and Georgia Tech, for integrated research, education and public outreach focused on the chemistry that may have led to the origin of life. The National Science Foundation and the U.S. Department of Energy have funded the research.

Many groups studying the origins of life have focused on RNA, which is believed to have pre-dated living cells. But RNA is a much more complicated molecule than a peptide. “Our studies have now shown that, if you just add water, simple peptides access both the physical properties and the long-range molecular order that is critical to the origins of chemical evolution,” Childers says.
