If you have an inquisitive mind, you will probably have noticed you learnt as much--if not more--about a topic by examining what its critics had to say, and not only its supporters. And you will doubtless have had occasion to either become agnostic, or to adopt a contrary position to what may be portrayed as orthodoxy.
What Meyer's book is *not* about is pushing religion. In the first two parts, and the first two chapters of the third (16 of 20 chapters in all), he looks at the orthodox view of evolution, which he reports accurately. I speak as someone with a degree in zoology and a little research experience in the subject; so whilst I don't claim to be an expert, I know enough to know he's not distorting anything. At the same time, his aim is to show that orthodoxy does not explain the evidence of the fossil record with respect to the Cambrian period, nor how so many new body plans could have arisen in such a comparatively short time, with no readily identifiable pre-Cambrian precursors.
He's not alone in this view, even amongst non-ID-supporting scientists. In fact, in Chapters 15 and 16, he examines alternatives to standard neo-Darwinism (or the New Synthesis if you prefer) being put forward by them as we speak. And generally, throughout the book, you will find copious references to the literature, as well as amplifying footnotes at the end of the book. Check out the references; chase up the bios of the chemists, biochemists, geneticists, paleontologists, geologists, etc. who in various ways and degrees challenge an orthodoxy that is frequently put across to the public as completely settled, completely unquestionable truth. I've done quite a lot of such checking, and I can report that many of them are hardly great fans of ID.
It's a fascinating read, and I hope that open-minded people will welcome a single tome that tells them so much about orthodox views, and at the same time offers evidence why the explanatory power of those might be open to question. It's evidence I personally find persuasive, whilst I accept others might not; but even so, if one has an open mind, it should be found engaging. All the more so if one isn't overly familiar with the subject of evolution: because it covers a great deal of ground in a pretty accessible way. It's quite an education, and I'm speaking as a trained and qualified (recently retired) educator. I learnt an appreciable amount that I didn't already know, and it clarified my understanding on a number of specific scientific points.
If you don't want to read about ID, fair enough: simply ignore the last 4 chapters, which is the only place he explicitly deals with it. He thinks ID explains what neo-Darwinism, and those other competing, but non-ID theories I alluded to earlier, can't. He may be right or wrong about that, but that has no bearing on the previous 16 chapters where he's demonstrated the severe shortcomings of neo-Darwinism in explaining the Cambrian explosion, during which the majority of phyletic body plans still extant today seem to have arisen: something that is absolutely contrary to orthodoxy, where body plans should have gradually appeared through time.
We should find evidence for a single tree of life (with an ultimate single ancestor in the first single-celled life form on earth, appearing maybe 3.8 billion years ago, well before the Cambrian began around 500 mya). However, what we actually find in the case of animals is what appears to be an "orchard", with separate animal lineages diversifying ever since the Cambrian. Top-down rather than bottom up: complex plans appearing early, not late.
It's true that there were a few body plans of multicellular organisms extant before the Cambrian in the pre-Cambrian (including the extinct Ediacaran fauna), and that one of those, that of the sponges, still persists to this day. But one can find nothing in the pre-Cambrian that is an obvious precursor of trilobites (early arthropods) or any of the other new body plans that emerged in the Cambrian (around 20 of them, still around today, including the Chordates to which humans belong--amongst a total of around 25-35 depending on the classificatory system applied).
It stretches credulity beyond breaking point to postulate that precursors in the pre-Cambrian were soft-bodied and hence not fossilised, when in fact soft-tissue preservation in both the pre-Cambrian and Cambrian is readily demonstrable. It stretches credulity to think that we haven't yet found precursors but one day will, when statistical analysis of the fossil record shows it's extremely unlikely we would have missed *all* such evidence.
The new Cambrian body plans must have come from somewhere, unless your idea is of an intelligence that can magic up something from nothing, but Meyer doesn't deny the possibility of common descent, and certainly not the reality of evolution in the sense of change over time. He fully accepts that the earth is billions of years old, and, one might wrily argue, that the fossil record means what it actually says: that neo-Darwinian gradualism doesn't occur at the macro-evolutionary level (e.g. the formation of new body plans), even if it might occur at the micro-evolutionary level (e.g. low-level species divergence within a genus). He doesn't even deny that random mutation and natural selection have a role to play at the micro-evolutionary level.
Meyer gives a very good introduction to the concept of Shannon information and how that contrasts with functional, or specified, information. Put simply, any random combination of, say, fifty alphabetic characters is as likely, and contains as much information, as any other. But only a very few would spell out a recognisable English sentence. Vanishingly few from the 26^50 (approx. 5.6 x 10^70) combinations would do so. The issue is enormously amplified when one considers a modest protein containing 150 amino acids, for which any of 20^150 (approx. 1.4 x 10^195) combinations are possible, but for which a vanishingly small proportion have been demonstrated to be likely to be of functional use to organisms.
Neo-Darwinists will insist that it isn't only random mutation that is involved in evolution, but crucially, natural selection. But before the latter can select for a mutation, it has to have occurred, and most mutations are likely to be harmful than beneficial. The problem gets even worse when it is realised that innovations may require a number of proteins to act in a coordinated fashion. These are the kinds of facts that are addressed in "post-Darwinistic", non-ID theories (such as evo-devo and self-organisation, neo-Lamarckism, neutral theories and natural genetic engineering) discussed in chapters 14 and 15, and I have to agree with Meyer, they aren't convincing either.
If there's one key theme throughout the first 16 chapters, it's to do with where *new* information comes from as organisms evolve over time. An enormous amount of specified information is required to change a putative pre-Cambrian precursor into a Cambrian one. Information, for example in the case of a trilobyte, enabling the formation of the complex arthropod exoskeleton and its accompanying muscles and ligaments, not to mention the appearance of complex compound eyes. The Cambrian predator, Anomalocaris ("strange shrimp"), up to a metre or so long, had very advanced compound eyes, only exceeded in complexity by present-day dragonflies. We even find primitive jawless fish (ancestors of lampreys) appearing in the Cambrian.
It's all quite astonishing and I can't for the life of me see how anyone would prefer to stick with the one theory that can't possibly explain it. I don't know what *does* explain it, but I have to hand it to Meyer, nothing currently explains it better than a postulate of intelligent input of some sort. He probably believes that is the Christian God, but by no means all ID proponents do. I even know of some people who are atheists who think that intelligence may in some sense be inherent in nature in everything from atoms to stars and galaxies to organisms. Maybe some non-ID explanation will eventually be forthcoming that better explains it, but for the moment, ID's at least worth consideration.
Darwin's Doubt is a fascinating read, and for its content alone, it's worth 5 stars. However, it is not entirely without fault, because in places it seems somewhat repetitive and in need of tighter editing, which might have reduced its size appreciably. So overall, I'll give it 4 stars along with a recommendation for any independent-minded person to read it. Don't pay a lick of attention to 1-star reviews from ideological neo-Darwinists who obviously can't bring themselves to read it, yet nonetheless feel it's okay to carpet-bomb the Web with their ill-informed comments. They have little integrity and even less good manners.
Meyer has written a groundbreaking classic. The weight of the science stands on its own merit, regardless of associations or origins. Like his nemesis Donald Prothero, Meyer has produced exquisite science, but unlike Prothero, he has produced it without recourse to adversarial language. The downside of this is that Meyer's work is weighty with words and evidence. It should have been made easier for non-experts to read: I had to work hard to be sure I'd understood it (as did even Amazon's highest-starred reviewer, Prof David Snoke). And it might even slip past people's awareness that Meyer fully supports the notion of evolution over millions of years. It is simply a key detail of evolution with which Meyer has issue, but it is a detail seen by many scientists in many relevant areas of research.
"Darwin's Doubt" takes its name from the one area of evolutionary theory in which Darwin himself expressed doubts - what is known in geology as the Cambrian Explosion. What geology shows is that after billions of years in which only sponge and single-cell fossils are found, representatives of nearly all the main groups (phyla) of animals suddenly appear, in a geological "explosion" of essentially five million years. This is a simplified picture but Meyer deals with anomalous details, like the fascinating Ediacaran fossils, without losing the overall perspective.
Meyer shows that the current evidence, while supporting evolution in principle, is totally ranged against the accepted modus operandi of Natural Selection. Damning evidence arises again and again, as the findings of statistical probability are applied to many different areas of evolution research. The official science has generally slid over these feasibility challenges; there has been little checking of statistical probabilities. Evolution "happens". Sure, all the evidence shows it happens. The issue is the modus operandi, the mechanism.
Meyer goes into the question of the likelihood of the selection of helpful mutations in enormous detail, mainly but not entirely working at the chemical molecular level, and with consistent support from the findings of other scientists, including many who are not ID fans. What Meyer draws together from all the cutting-edge research, and from quoting others' estimates of statistical probabilities, is that the probability of "natural selection" of favourable mutations to the point of new species creation is vanishingly small in practice, in any natural process of evolution.
Chapters 9 and 10, devoted to the issues of mathematical probability, must be understood in order to grasp this failure of Evolution's presumed modus operandi. It is the failure to estimate statistical probability that has enabled evolutionists who believe in Natural Selection to continue, in all areas of evolution, to make claims which assume the workings of chance mutations in chemical processes. Meyer demonstrates again and again that the statistics of probability show that mechanistic Natural Selection is impossible even over a timescale of millions of years. It is only in the light of such vanishingly small likelihoods, demonstrated at all the cutting edges of evolution research (and which a growing number of scientists acknowledge) that Meyer finally suggests that we could consider whether a hypothesis of "intelligent design" could actually help Science begin to grapple legitimately with an otherwise intractable mystery.
It is clear that many scientists privately support such an approach. David Snoke actually quotes what would appear to be a typical example of the many US scientists who would like to speak out openly, if they were not in fear of their academic lives being cut short, if it were to become known that they supported, or even simply expressed desire to explore, the theory of "intelligent design". It is a shame that many who are rightfully critical of "young earth" Creationism conflate those claims with the very different claims of Intelligent Design. It is a shame that Meyer's pure science here, which has not the slightest hint of either ad hom or of slanting the balance of evidence, should be conflated with the work of activists. Meyer's work stands on its own merit, whatever the funding and whatever the attitudes of others who support him. Given the history, it is understandable, but still a crying shame that such conflation has reached screaming pitch in the US, and that this has seriously compromised freedom of speech in the context of academic science - and is now seriously preventing Evolution Science from advancing.
Meyer's hypothesis does not limit the freedom of scientists to do research. Rather, it gives them wider resources on which to draw for further investigations. Thankfully, there is a growing number of scientists, many of firstrate calibre and qualifications, but still mainly outside the accepted halls of Science, who are working with phenomena which simply do not fit the current scientific laws of reality. This all looks like good scientific potential. But it does present a big challenge to those who believe that all scientific hypotheses, and even Scientific Method, have to exclude supersensible levels of reality. For there is nothing in the essence of Scientific Method which precludes its application to supersensible levels of reality.
The scientific and statistical evidence Meyer puts forward stands on its own merit, and should therefore not be associated with any "fundamentalist Christian" takeover threat. It is perfectly feasible to separate the issues - as should always be the case. I say, Dismantle the current evolutionists' Berlin Wall! Meyer has provided the cool mathematical evidence that openness to higher realities than what the materialistic explanation of Evolution allows, is now needed, for the sake of Evolution and indeed Science itself.
I have again subtly rewritten my review, to further separate the pure science from the activism on all sides. It now provides slightly clearer answers to the many points commenters have made. But I cannot make anyone read me more carefully if they have already closed their mind. Yet the science cannot advance until the shouting/repressing stops ON ALL SIDES!!!!!! (!) Shouting/repressing usually betrays insecurity: is fundamentalist Christianity inadequate on scientific truth, and fundamentalist Science inadequate on evidence for God? Why not work to build bridges and start mending past inadequacies and faults?
Both Science and Christianity are essentially and ideally about truth, despite the failings of both in practice. But only Christianity has built into it the pursuit of both Love and Truth as "moral imperatives". It should therefore fall to Christians to take up the work of reconciliation, which has to listen to the other side, listening for their truths however partial, listening for the emotional roots of grievances. I haven't been able to do complete justice in this respect to my commenters. It has been hard work to try to winnow any just grievances from the bombardment, wearisome repetition, simple irrelevance, and subtly ad-hom comments that have nothing to do with Meyer's science. But I've done what I could and hereby put out the request for more attention to this in future.
5.0 out of 5 stars
It has taken me quite a long time to read this book (all 413 pages, excluding reference material), but it was worth the perseverance! Not because the book was badly written, on the contrary, I found it superbly written - and very stimulating... The perseverance was associated with looking up the substantial amount of notes, bibliography and other allied documentation.
Somewhat like his previous book, `Signature in the Cell', Stephen Meyer has presented us with a `milestone' book i.e. one which, in my opinion, substantially places `Intelligent Design' on the scientific `map'.
The book is very well set out; in three main parts, with a logical series of chapters making up each part.
Part one - "The Mystery of the Missing Fossils"
Stephen Meyer gives a good historical background to Charles Darwin's book, `On the Origin of Species'; he even calls it a "singular achievement"..., but he swiftly moves on to describe the main problem facing Darwin's hypothesis, namely, the `Cambrian Explosion'.
Meyer also spends time introducing contemporaries of Darwin, such as Agassiz and Sedgwick (both of whom were, respectfully, leading palaeontologist and geologist of the day). They had serious doubts about Darwin's proposition of the abrupt appearance of the Cambrian creatures. Darwin proposed that the geological record was "a history of the world imperfectly kept" rather than anything seriously wrong with his theory, but Agassiz and Sedgwick would have none of it.
As expected, the Burgess Shale is given its own chapter, with good historical coverage of Charles Doolittle Walcott, the discoverer, also director of the Smithsonian Institution. Sketches of the fossilised creatures are excellent, with good explanations about morphological diversity and various family trees.
There is a very good chapter dealing with `punctuated equilibrium', the proposal by Eldredge and Gould to explain the systematic `gaps' in the fossil record, where, according to neo-Darwinian theory, there ought to be a continuum of transitional forms leading from one body plan to another.
Meyer explains fully why "punk eek" fails as an explanatory proposal for the origin of complex creatures found within the fossil record.
All of the supportive diagrammatic sketches that Meyer includes, within his text, are superbly produced and very easy to understand. This applies throughout the book.
Part two - "How to Build an Animal"
This part is principally about biological information, and in this respect, there is an overlap with Stephen Meyer's first book `Signature in the Cell.'
There is a short explanation of Shannon information, and how this differs from functional information (or specified information) found in living organisms.
Meyer waxes lyrical about the contribution made by Murray Eden in respect of the "Mathematical Challenges to the Neo-Darwinian Interpretation of Evolution". Murray had pointed out that "the combinatorial space corresponding to an average-length protein"... is about 10 to the power 325 "possible amino-acid arrangements. Did the mutation and selection mechanism have enough time - since the beginning of the universe itself - to generate even a small fraction of the total number of possible amino-acid sequences corresponding to a single functional protein of that length? For Eden, the answer was clearly no." This was in the 1960's - but according to Meyer, the `mathematical challenge' has been an issue that has not been satisfactorily resolved ever since. He spends a substantial amount of space justifying this position through the work of Douglas Axe, who in the late 1980s examined the then accepted work of Richard Dawkins in his book The Blind Watchmaker, in which Dawkins used a computer programme to illustrate how natural selection could "generate the Shakespearean phrase: "Me thinks it is like a weasel.""
Intelligence was found to pervade this kind of `evidence' to prop up the Neo-Darwinian model...
Meyer goes on to build on his case that the mathematical challenges have remained un-bridged throughout "the various experiments and calculations performed between 2004 and 2011." Although Meyer makes a substantial case here, he is too reliant upon the work of too few specialists, in my opinion.
Meyer's section on "Developmental Gene Regulatory Networks" was particularly interesting - and helped to introduce even greater complexity issues in the origin of body plans etc... Likewise, the section on "the Epigenetic Revolution."
Part three - "After Darwin, What?"
In this final section, Meyer takes on the post-Darwinian world - and theories of self-organisation, such as the work of Stuart Kauffman and Stuart Newman.
Cutting to the chase, Meyer pus it like this: "what needs to be explained in living systems is not mainly order in the sense of simple repetitive or geometric patterns. Instead, what requires explanation is the adaptive complexity and the information, genetic and epigenetic, necessary to build it." (pg. 305). He makes a strong case in justifying this statement!
In like manner, Meyer presents a robust summary of his issues with "evo-devo" and "Lamarckian mechanisms."
All of the foregoing builds a strong case to support his final four chapters:
"The Possibility of Intelligent Design", "Signs of Design in the Cambrian Explosion", "The Rules of Science" and finally "What's at Stake"....
Meyer spends some time telling "My Story", which explains his initial interest in intelligent design through to holding robust scientific reasons for his belief in "indicators that make intelligent design scientifically detectable from the evidence of the living world."
All in all, this book is far from some form of simplistic `biblical creationism', as suggested by other reviewers, but, in my view, a logically and soundly argued piece of scientific research, which draws conclusions toward an `inference to the best explanation.'
Coupled with his former book `Signature in the Cell', Meyer makes the strongest case yet for `intelligent design' - and places it squarely within the scientific domain. To reject it as pseudo-science would be blind prejudice - and damaging to science in the long term, simply because ID makes testable predictions. Examples of these are given in this section!
This is how Meyer concludes his book: "The theory of intelligent design is not based upon religious belief, nor does it provide a proof for the existence of God. But it does have faith-affirming implications precisely because it suggests the design we observe in the natural world is real, just as a traditional theistic view of the world would lead us to expect. Of course, that by itself is not a reason to accept the theory. But having accepted it for other reasons, it may be a reason to find it important."
In other respects, the book has been beautifully produced by HarperOne, is superbly illustrated and documented - with some nice colour plates of fossils to boot!
I heartily recommend this excellent book!!
