James Shapiro: an honest naturalist admired by ID supporters

As a pro-ID person, I am naturally suspicious of naturalistic scientists. They always say that material forces and chance can explain every single thing in nature, and there are no effects in nature that are best explained by an intelligence. Well, some in nature are best explained by unintelligent causes alone. But I think there are some effects in nature that are more like meaningful sentences or meaningful computer code – and that those are best explained as a result of an intelligence.

One effect in nature where that is clearly analogous to language/code is the biological information in proteins and in DNA. ID people keep telling naturalists that functional information in the first living cell cannot be generated by blind forces in the time available in Earth’s history. But naturalists always seem to diminish the problem and say that blind forces can create information. Well, most naturalists do.

Here’s one who doesn’t, though: James Shapiro. Dr. Shapiro is a microbiologist and a professor in the Department of Biochemistry and Molecular Biology at the University of Chicago. His undergraduate is from Harvard University.

He is very frank about how much naturalistic mechanisms can explain when it comes to the origin of life.

Around here we have a lot of respect for microbiologist James Shapiro, who had the guts and integrity to come over to ENV recently and spar over evolution with William Dembski, Doug Axe and Ann Gauger. Besides having a new book out that details his own dissatisfactions with conventional Darwinian evolutionary theory and that champions a provocative alternative view, Shapiro also blogs at the Huffington Post.

He continues to win our admiration, while evoking some poignancy as well.

In one post that got a fair amount of attention he had some sensible things to say to fellow evolutionists. Rather than hide behind “absolutist statements like ‘all the facts are on my side,'” as his University of Chicago colleague Jerry Coyne does, Shapiro advocates “active engagement” with Darwin critics. Enter into the controversy over evolution, he says, rather than pretend it doesn’t exist.

Perhaps even teach about it? Shapiro doesn’t go that far, but the permissibility of admitting the truth even to young people would seem to follow from his premise:

We need to demonstrate that evolution science is alive and well, as well as show how it is making remarkable progress through the application of molecular technologies — even though it does not have all the answers.

To the thoughtful scientist whose job is to uncover natural processes, this is surely a better way of advocating the scientific method than dogmatically asserting that we found all the scientific principles we need in centuries past.

Evolution supporters, he counsels, should admit they don’t have all the answers, including on a key question like the origin of life. In a remarkably candid statement, he writes:

In order to be truthful, we must acknowledge that certain questions, like the origins of the first living cells, currently have no credible scientific answer. However, given the historical record of science and technology in achieving the “impossible” (e.g., space flight, telecommunications, electronic computation and robotics), there is no reason to believe that unsolved problems will remain without naturalistic explanations indefinitely.

I don’t mind a naturalist who is honest about what we do and do not know.

More:

Surely there’s room to question Shapiro on why our ability to fly to the moon gives grounds for certainty that a purely “naturalistic” explanation of life’s origin will be forthcoming. Space flight is an accomplishment enacted in a material world but, more to the point, it’s a triumph of engineering — aka, intelligent design. It could not be accomplished at all without the direction of purposeful designers.

But note the implicit agreement with Stephen Meyer (Signature in the Cell: DNA and the Evidence for Intelligent Design): materialist explanations for “the origins of the first living cells” have, to date, indeed all miserably failed. In his book, Meyer shows how the evidence points persuasively to the action of some source of intelligent agency. Under the circumstances, if Shapiro is right, that would make intelligent design by default the lone viable theory of life’s origin.

Apart from gesturing to the advance of technology as a reason for keeping faith in naturalism, it would be interesting to know how Shapiro responds to Meyer’s case.

James Shapiro has debated with pro-ID people before. I have a set of audio cassettes from WAY WAY BACK which contains a debate between Robert Shapiro and Walter Bradley, whose lectures on the evidence for design in nature I have featured before. Although some naturalists like Richard Dawkins run away from debates, some, like Shapiro do not. And that’s good for science.

If you want to read a great book on what intelligent design is really about, you really need to read Signature in the Cell. This is the best on the argument for intelligent design in nature from the evidence of proteins and DNA. We are still waiting for a really great pro-ID book on the Cambrian explosion, the sudden origin of all major body plans 540 million years ago – but maybe Dr. Meyer is already working on that now, since he published a peer-reviewed paper on it in a science journal, a while back.

Is Skeptic magazine keeping up with the progress of science?

Not if the progress of science undermines the speculations about a naturalistic origin of life. In their latest issue, Skeptic magazine espouses the old, discredited Miller-Urey experiments from half a century ago. The old science is Darwin-friendly. But is that old science still current?

Consider this post from Evolution News.

Excerpt:

Stanley Miller had not in fact “simulated atmospheric conditions on the early Earth.” And this has been known for quite a long time. Origin of life theorist David Deamer states:

This optimistic picture began to change in the late 1970s, when it became increasingly clear that the early atmosphere was probably volcanic in origin and composition, composed largely of carbon dioxide and nitrogen rather than the mixture of reducing gases assumed by the Miller-Urey model. Carbon dioxide does not support the rich array of synthetic pathways leading to possible monomers . . . .

(D.W. Deamer, “The First Living Systems: a Bioenergetic Perspective,” Microbiology and Molecular Biology Reviews, Vol. 61: 239 (1997).

As I discuss here, there’s very good reason to understand why an atmosphere on Earth of volcanic origin would not contain methane or ammonia. A 2010 paper in Cold Spring Harbor Perspectives in Biology states that the chemical properties of the Earth’s mantle have not changed over time, and thus if volcanoes don’t produce appreciable amounts methane and ammonia today (which they don’t), then they also wouldn’t back then:

Geochemical evidence in Earth’s oldest igneous rocks indicates that the redox state of the Earth’s mantle has not changed over the past 3.8 Gyr (Delano 2001; Canil 2002).(Kevin Zahnle, Laura Schaefer, and Bruce Fegley, “Earth’s Earliest Atmospheres,” Cold Spring Harbor Perspectives in Biology (2010).)

The papers cited in the quote above confirm this point. For example, Canil’s 2002 paper in Earth and Planetary Science Letters found that vanadium redox states in peridotite-bearing mantle xenoliths and Archean cratons imply that Earth’s mantle was just as oxidized in the Archean as it is today. The paper concludes:

Abiotic synthesis of molecules and hydrocarbons that can lead to life in early Archean mantle-derived volcanic gases requires they contain significant H2 and CO, but such reduced components are not supported by results of this and many other studies, which imply a scenario of Archean mantle redox not unlike that of today. Life may have found its origins in other environments or by other mechanisms.

(Dante Canil, “Vanadian in peridotites, mantle redox and tectonic environments: Archean to present,” Earth and Planetary Science Letters, Vol. 195:75-90 (2002) (internal citation removed).)

The situation is summed by authorities Kasting and Catling as follows: “For the 4 billion years for which a geological record exists, no evidence for a pronounced change in mantle redox state exists.” (James F. Kasting and David Catling, “Evolution of a Habitable Planet,” Annual Review of Astronomy and Astrophysics, Vol. 41:429-463 (2003).)

Skeptic magazine cannot be skeptical on the origin of life. They have to affirm a naturalistic origin of life, because they assume that there was no intelligent cause of the origin of life, before looking at the evidence. They affirm that the universe is eternal, before looking at the evidence. They affirm that there is a multiverse to explain the fine-tuning, before looking at the evidence. They affirm that habitable planets are common, before looking at the evidence. They assume that a gradual string of pre-Cambrian fossils exists, before looking at the evidence. They believe in man-made catastrophic global warming alarmism, before looking at the evidence. Evidence is very, very bad for skeptics. Which is why they oppose the progress of science and have to go back fifty years to the speculations. They don’t like the progress of science. They believe what they want to believe. And that’s why they don’t want to debate anything, but instead refuse to hire people who disagree with them – or fire them if they are already hired.

It’s Skeptic magazine versus the scientists. Religion versus science. The pre-supposition of naturalism versus reality.
