Argument from Design at the cellular level, November 22, 2000
Michael Behe's an apologist, by far the best apologist I've run across, for the "argument from design" objection to evolutionary theory. (Essentially argument from design amounts to "See that watch? How could it have come about without a watchmaker? How could any of its parts have originally 'evolved' independently? If they didn't, how did the watch spring up out of nowhere?" And so on.)Intelligently, Behe recognizes that the argument from design has been responded to pretty thoroughlyat the species level. (For example, evolutionary theory has worked out how the bones of the ear evolved from a bone that articulated reptilian jaws.) So Darwin's Black Box, unlike countless somewhat apoplectic "creationist" writings, chooses the territory for its argument very carefully. Behe concedes natural selection as a force at the level of complete organisms: certain Amazon reviewers seem not to have noticed that he does allow humans and apes a common ancestor, for a glaring example. The narrowly defined argument Behe wants to stake out is in the biochemical realm. There, he thinks, he can make a case for "irreducible complexity." In short, he thinks he can convince us that the interdependent, complex systems that constitute such things as cilia in cells could not possibly have come about as the piecemeal result of natural selection. The first half of this book is comprised of lengthy, extremely accessible and enjoyable descriptions of exactly how the smallest cellular mechanisms work. The latter half consists of an attempt to assert the irreducible complexity of those mechanisms. If cilia in cells can't be accounted for by natural selection, says Behe, then there must be intelligent design at work on that level. To synopsize: Behe concedes the evolution of organisms, but argues that the complexity of life at the cellular level proves the existence of "intelligent design" -- of God. God, in a sentence, is in the cellular details for Behe. I wouldn't dream of endorsing or refuting this book's arguments here. I'm not here to blow on already hot embers for anyone; I just thought an intelligent reader would want to understand the basic outlines of what this book tries to do. Some of the positive reviews from religious types seem not to have been based on this book at all...

A biochemist responds to Behe's challenge, March 23, 1999
By A Customer
As a biochemist interested in DNA structures and the origins of complex systems, I was delighted to hear that someone in my area of research had written a book on this subject. Behe does a good job of trying to convey the problem. If anything, molecular systems are even MORE complex than detailed in his well written and wonder-filled descriptions. However, I was surprised and frustrated to find the use of poor logic and factual errors throughout the book. For example, Behe can't find articles that he LIKES about the molecular evolution of flagella, so he then proceeds to claim that these articles simply don't exist. There are entire textbooks with titles like "Molecular Evolution" (search Amazon.com and see for yourself), and yet Behe insists that nothing has been written on the subject, and concludes that the reason for this is because no one has been able to find any detailed evidence for molecular evolution.One of the examples cited of "irreducible complexity" is the bacterial flagellum. Behe claims that 40 proteins are necessary for a fully functional flagellum. Whilst this is true for E.coli, flagella in many bacteria are made from fewer proteins - for example, in the bacterium that causes syphilis (Treponema pallidum), there are a total of 38 flagellar proteins; in the bacterium that causes lyme disease (Borrelia burgdorferi), there are only 35 flagellar proteins; finally, in a bacteria associated with ulcers (Helicobacter pylori) there are only 33 proteins necessary to form complete, fully functional flagella. It is likely that as new bacterial genomes continue to be sequenced (at the rate of about one a month!), organisms will be found which require even fewer genes to make a completely functional flagella. So this "irreducible complex" of 40 proteins has shrunk to 33 proteins, in the past 2 years of research! Behe's argument is that EVERY ONE of the 40 proteins are necessary. Obviously 7 of those 40 aren't completely necessary. Maybe it's only 30 or perhaps even 20 proteins that are absolutely necessary? It's hard to say, but it is very dangerous to make such dogmatic statements as "this system is irreducibly complex", especially when the system is made up of proteins that have other normal functions in the cell, apart from flagella - such as the GTPase proteins. For a more fair treatment of the subject of flagella (and bacteria and molecular evolution in general), I can happily recommend reading "The Outer Reaches of Life", by John Postgate (also available through Amazon.com), which is an excellent treatise about bacteria written for the "non-scientific reader". Of course there is a need to explain the origins of biochemical complexity. But declaring "intelligent design by a miracle" to be this method is neither scientific nor helpful. I guess my advice would be similar to that of Huxley about Darwin's Origin of the Species - please read Behe's book and decide for yourself!

Good reading, good explanations, too short., December 5, 2001
I don't really think the harshly negative reviewers get the point, nor are they being fair. Biochemistry was my undergraduate major, and I worked as a geneticist for a few years afterward. From that point of view, I don't think Behe's arguments are inherently flawed or bad science.As Behe points out, there is a disconnect in evolution's explanation of microscale processes (e.g. biochemical: protein-protein interactions) compared with macroscale processes (e.g., functional gene mutations such as commonly seen in bacteria). It is difficult to see how mostly benign chemicals, that react primarily with respect to strong or electromagnetic forces, necessarily combine in self-advantageous (or self-disadvantageous), reproducible ways under a competitive survival paradigm. Einstein and his group pointed out that gravity does not work on the chemical level (i.e. microscale). Behe merely points out the same thing with respect to evolution in biomolecules. My only complaint was that Behe inferred the intelligent design aspect too soon in the book. I would have liked more examples of biological irreducible complexity since I'm not sure that's the winning argument. That is, if you take away one piece, or that the mousetrap is made of paper, perhaps it functioned some other way than as a mousetrap. I thought the ATP synthesis was a nice example, but I found myself wanting more. I thought the killer point Behe made, that I agree with, is the intolerant intellectual atmosphere so pervasive in many areas of science, particularly biology. I believe this has a large a priori effect on the approaches taken in research, or on reporting findings. This intolerant culture might come from the vehement attacks by creationists on the other side, which may in turn tend to galvanize the molecular biology community. Who knows? I do, however, believe scientists are too quick to discredit, or label as a creationist or idiot, anyone who challenges the evolution dogma on any scale. Scientists give up too quickly if they think evolution is the sine qua non on every level. The little changes to big changes cliche is tired and needs more. Behe points out, pretty simply I might add, that it is no sillier to say that God fills the gaps than to say evolution fills the gaps. Let's face it, evolution simply cannot explain microscale biochemical processes. Perhaps something else does, but evolution doesn't. Cheers to Behe.
