Even on his birthday, don’t say Darwin unless you mean it (updated)

How Darwin’s name is taken in vain, with mini-reviews of some of the worst offenders. And when I wrote about this last year, I did not expect to have to add a US Vice-President to their number.

Charles Darwin never thought of evolution as anything other than a theory. He hoped that someday it would be proven by the fossil record but did not live to see that, nor have we. – Representative (now Vice-President) Mike Pence, 2002, via Forbes


From Darwin’s Notebook B, 1837

Don’t say Darwin unless you mean it. Don’t say theory when you mean historical fact. And don’t say you believe in evolution, when you mean you accept it on the basis of the evidence.

Don’t say Darwin unless you mean it. Above all, don’t say “Darwin” when you mean “evolution”. It’s like saying “Dalton” when you mean atoms. Our understanding of atoms has moved on enormously since Dalton’s time, and our understanding of evolution has moved on similarly since Darwin’s. Neither of them knew, or could have known, anything about what caused the phenomena they were talking about, and both would be delighted at how thoroughly their own work has been superseded.

 Imagine if a lot of people decided that atomic theory was against their religion. We would see a parallel world of sacred science, in which molecules were “intelligently constructed”, and real chemistry would be referred to as Daltonism, or possibly, these days, neo-Daltonism. The scientific dissidents


From John Dalton’s A New System of Chemical Philosophy (1808)

from Daltonism would invoke Dalton’s name on every possible occasion, and draw attention to the many inadequacies of atomic theory as he presented it in 1808. Dalton didn’t know anything about the forces that hold atoms together, which depend on electrons and quantum mechanics. In fact, he didn’t even know about electrons. Worse still, he was hopelessly muddled about the difference between a molecule of hydrogen and an atom of hydrogen. He thought that the simplest compound between two different elements A and B would have the formula AB, so that water must be HO, not H2O. And of course he knew nothing about the origin of atoms, a problem not solved until the 1950s, over a century after his death. Shot through with errors and inconsistencies; nonsense, the lot of it!

Darwin was ignorant of transitional fossils, and in words still quoted by creationists deplored their absence as the greatest objection to his theory. He was equally ignorant about the origin of biological novelty, which comes from mutating genes. In fact, he didn’t even know about genes. And because he did not realise that inheritance occurred through genes, he could not explain why favourable variations were not simply diluted out.

It would be decades after his death before we could even speculate coherently about the origins of life, and despite tantalising clues it remains a largely unsolved problem. But despite this, we have learnt an enormous amount since the publication of On The Origin of Species, and everything that we have learnt is consistent with, indeed requires, the key concepts of evolution and common descent.

Finally, he saw evolution as driven by natural selection, embracing Herbert Spencer’s reference to “the survival of the fittest”, whereas now it is increasingly apparent that much evolution depends on neutral drift, and that major evolutionary changes may even require passing through marginally less fit intermediates (see my next post here). So, ironically, the term “Darwinian evolution”, describing as it does evolution driven by natural selection, is now used in the scientific literature to refer to just one special case.

And while we’re on the subject of how words are used, don’t say “theory of evolution” when you mean the well-established facts of change over time and common ancestry. And if you find yourself in the position of explaining the difference between a scientific theory (coherent intellectual structure developed to explain a range of observations), and the use of the word “theory” in everyday use (provisional hypothesis), you have blundered into a morass. Back out again.

And don’t say that you “believe in” evolution. It’s not a matter of believing, with its suggestion of committing oneself beyond the evidence; it’s a matter of accepting where that evidence leads.

“Accepting”, indeed, might be a very useful word, especially when dealing with religiously motivated creationist students. If such a student accepts that the evidence points towards evolution, and understands why, then any religiously motivated inner reservations are a matter for the student, not for you.

ExploreEvolutionBut back to Darwin. Why is discussion of evolution still saturated with his name? In part, I think, because that’s the way his opponents want it. By identifying evolution with Darwin, they continue to breathe life into the controversies of the mid-19th century. At the same time, it helps them pretend that modern biology is just one individual’s point of view, rather than a mature science based on the work of thousands of investigators. Recently, creationists have even taken to invoking Darwin himself for their cause, in such titles as Darwin’s Doubt and Darwin Strikes Back. This is an extremely powerful rhetorical tool, whereby anything that puzzled Darwin can be used to undermine us “Darwinists”. Closely related is the device of presenting creationism under the guise of even-handed debate, as when a creationist pseudo-textbook (which mentions Darwin on almost every page, but not in the index) calls itself Explore Evolution; the arguments for and against neo-Darwinism, or in the list below, where a creationist comic goes by the name, What’s Darwin got to do with it? A friendly discussion …

DarwinsBlackBox You can see what I mean if you just look at the names of the books written by the enemies of scientific biology, from Darwin’s Doubt (Meyer, 2013) back to Darwin’s Black Box (Behe, 1996) and beyond. There are other examples, such as The Darwin Conspiracy (Roy Davies, 2006), which portrays Darwin as a plagiarist, and, while checking its details, I discovered an even more lurid book of the same name by John Darnton, which portrays him as a murderer. To be fair, Darnton does not pretend that he is writing anything other than fiction, although surely he was writing with half an eye on the creationist market.

To further test my idea, I went online to, and typed “Darwin” and “Darwinism” in the search window (I regularly search on Amazon, but prefer to buy from Better World Books or Wordery). Here are some of the books by creationists that I came up with; a lot of the names were all too familiar, but I never realized that Rick Santorum had actually got his name on a book.  There were also references to “materialist neo-Darwinism”, but since I don’t pretend to know what a “materialist” is, and whether I or for that matter Darwin would qualify, I decided to let those ones go. The most recent entry (December 2016) is one I heard about through the Discovery Institute, who also published it.

Darwin's House of Cards: A Journalist's Odyssey Through the Darwin Debates by [Bethell, Tom]

Darwin’s House of Cards: A Journalist’s Odyssey Through the Darwin Debates, 2016, by Tom Bethell who “presents a concise yet wide-ranging tour of the flash points of modern evolutionary theory, investigating controversies over common descent, natural selection, the fossil record, biogeography, information theory, evolutionary psychology, artificial intelligence, and the growing intelligent design movement.” Bethell is a philosophy graduate, despite which he repeats the myth [2] that Popper regarded evolution as mere tautology.

1] Betsy DeVos herself has not ccommented publicly on the issue. When asked about junk science teaching at her confirmation hearing, she said that she supports science teaching that “allows students to exercise critical thinking.” In the US,this unexceptionable objective is code for teaching, as if scientifically valid, denialist objections to evolution and climate change science.

2] At one point, Popper described Darwinism as “not a testable scientific theory, but a metaphysical research programme—a possible framework for testable scientific theories.” However, as other passages show, he is using “Darwinism” here in its proper restrictive sense of the theory that evolution is driven by the survival of the fittest. Popper repeatedly made clear his acceptance of the historical fact of evolution; for a full discussion see here.

A Creationist Speaker Comes to Town

Long but detailed; updated resources include rebuttals to creationist claims, including dinosaur soft tissue, and teaching exercise on Lucy. I have mined this for links. There is also a discussion of bible-basd arguments, for those (like the author) to whom such thngs are important.

Letters to Creationists

By the early 1800s European geologists (many of them devout Christians) realized that the rock layers they observed had to be far older than the 6000 years allowed by a literal interpretation of Bible chronology. For instance, as discussed here , angular unconformities like that shown below could not been formed in the course of the one-year-long Flood of Noah.

Angular Unconformity at Siccar Point, Scotland. Siccar Point, Scotland (Photo: Wikipedia “Hutton’s Unconformity”) Angular Unconformity at Siccar Point, Scotland. Siccar Point, Scotland (Photo: Wikipedia “Hutton’s Unconformity”)

Numerous other evidences for an old earth have been observed by scientists over the past two hundred years. These include fossil soils, and massive deposits of salt and of limestone in the midst of sedimentary rock layers, and tens of thousands of annual layers in lake bottom deposits (“varves”) and in glaciers (see Some Simple Evidences for an Old Earth). We can trace, in reasonable detail, the movements of the sections of earth’s crust over the…

Young Earth Creationists arguing in circles

Relative dating from sedimentology dates back some 200 years, as beautifully explained here by my friend, field geologist and Anglican priest, Michael Roberts, with illustrations from what he has seen himself, while we have now had absolute radiometric dates for over a century. Index fossils are used only to establish that rocks are the same age, and the way creationists manage to forget this fact is indeed miraculous.

This piece gains added interest because of its first-hand accounts, both of geological exploration, and of attempts to persuade creationists to accept the results.

Evolution is wrong as it is a circular argument from the age of fossils worked out from evolution

Yes, it is the old chestnut of Young Earthers that the age of rocks is based on a circular argument from evolution. It took me back to 1971 when I made the felicitous mistake of going to L’Abri to sit at the feet of the evangelical guru Francis Schaeffer. I arrived ther all bright-eyed and bushy tailed thinking of all the wondrous things I would learn in the next four weeks. I learnt much but not what I had expected.

On my first morning i was sent to Shaeffer’s son-in-law Udo Middlemann to discuss what I would study. I explained that I was going into the Anglican ministry and had just returned from 3 years working as an…

Historical Science: How do We Know a Fish Fossil is a Fish Fossil?

Creationists argue that historical science is different from, and more uncertain than, present-day observational science. But their choice of examples shows that they themselves don’t really believe this.

Naturalis Historia

The difference between what young earth creationists like to term “operational” or “observational” science and historical science doesn’t have the sharp distinction they like to project to their audience.  I was reminded of this recently when I had an opportunity to hear Tommy Mitchell speak at a local Answers in Genesis conference a few weeks ago.  One particular talk was entitled:  Jurassic Prank:  A Dinosaur Tale.  In it Mitchell presents the young-earth case that dinosaurs lived with man as recently as a few thousand years ago.  The “tale” of course is that scientists have been telling us that dinosaurs died out millions of years before man existed.  You could say the punchline to the entire talk was that the public has been punked with regards to the truth about dinosaurs.

There are many lessons to be learned from this talk but I want to focus on one seemingly simple observation that Mitchell makes.  Below is a YouTube version…

Is “The Imminent Demise of Evolution” still imminent?

The demise of evolution, and of the geology necessary to support it, has been imminent since 1825. I hear and tremble.

My friend the rev Michael Roberts has reblogged my link here, with reference to his own experience. Michael is Anglican Priest, geologist, and historian, and has been following Creationist infiltration into the UK churches  for some decades.

Troy Britain’s piece reblogged here refers in turn to G.R. Morton’s classical compilation. Morton’s piece was originally posted on Answers in Science. The link from Morton to Answers in Science failed to work for me, but I am happy to say  that a direct link, here, works admirably as a source and resource.

Playing Chess with Pigeons

Ten years ago, in 2006, intelligent design creationistWilliam Dembski predictedthat in a decade evolution would be toast:

LOUISVILLE, Ky. (AP) – To William Dembski, all the debate in this country over evolution won’t matter in a decade.

By then, he says, the theory of evolution put forth by Charles Darwin 150 years ago will be “dead.”

Yeah, well…

Meanwhile I stumbled uponthis today (dated 11-17-2016) from young Earth creationistRichard William Nelson:

Despite a flood of challenges since the publication of The Origin of Species in 1859 by Charles Darwin and more than 150 years of unprecedented scientific efforts in the history of mankind to prove otherwise, the evidence examined in nature tooled with unprecedented technology continues to be compatible with the Genesis record written by Moses…

Geology, evolution and Christianity in the 19th century

This by my friend the geologist, historian, and Anglican priest Michael Roberts, reminding us that the acceptance and active participation of clergymen and other believers in the emerging sciences of biology and evolution dates back more than three centuries.

Peddling and Scaling God and Darwin

If you read many historical studies of Britain in the 19th century, you will read that a major conflict was over science. That claim is overstated. Here is a brief overview.

 Geology (Deep Time) and Evolution?

From reading many books on church history, general history or popular science, it is easy conclude  that advances in geology in the eighteenth and early nineteenth centuries and then evolution after 1859 had gradually been undermining belief in God as Creator as well as an almost official literal reading of the early part of the book of Genesis. The actuality is rather different.


Genesis 1 from a 1611 copy of the KJV

So often the work of Archbishop James Ussher is cited as the “official” view of the churches. In 1656 he published his Annales Veteris Testamenti (Annals of the Old Testament) which gave the famous date of creation as 4004BC. (Actually, it has…

Homage to Jack Chick, (April 13, 1924 – October 23, 2016); repost of How to lie about radiometric dating, evolution, and even nuclear physics

Now that he is dead, let us play Jack Chick the compliment of treating his ideas as seriously as we did when he was alive. I am sure he would not have wished otherwise.

And so, in his memory (he died on Sunday) I am reposting my analysis of one of his pieces that I found particularly interesting [update: Americans United for the Separation of Church and State have also reviewed his life and work, here]:

How to lie about radiometric dating, evolution, and even nuclear physics

Have you heard the one about the live snail with a carbon-14 age of 3000 years? Or the lava erupted in 1800 in Hawaii with a potassium-argon age in the millions? It’s all true, true I tell you. But does this signify a major problem with radiometric dating?

Spoiler: no.

I don’t know who first dug up these examples, but they were popularised by the creationist comic-book writer Jack Chick, in a publication called “Big Daddy”. The first page, available here, shows a well-primed creationist student arguing with a singularly ill-informed biology professor. The professor has been leading such a sheltered life that he’s never met these creationist arguments before. And he doesn’t understand anything about evolution or dating of rocks or embryology or indeed anything else. Surprise! the student wins! A skilled cartoonist, Jack Chick manages to squeeze the largest number of fallacies into the smallest number of words. There is a crib sheet at the end of this post, listing all the fallacies I spotted myself; I just reached double figures but there may be more.





Of course, it doesn’t help that the Professor doesn’t know anything about whale ancestors:


Or that the student is allowed to make the most absurd statements unchallenged, on the basis of a video by Kent Hovind:


But there’s more! At the end of page 1, which is also the end of your free sample I’m afraid, the student converts the Professor by pointing out that no one has ever actually seen gluons:



But fear not; an answer is at hand, in the very next frame:

So Jesus must be the force that holds the atomic nucleus together. Convinced by this reasoning, the Professor accepts Jesus, announces that as a result he can no longer teach evolution, and is sacked.

Jack Chick, by the way, has just published another comic book at the age of 92. In it, a bright young man from a good Christian (i.e. creationist) home is seduced by Satan into believing in evolution, and when we last see him is heading straight for damnation. In the words of one of Satan’s many horned helpers, “Joe trusted evolution, not God, and became a jobless party animal.” And a criminal and a drug addict, and covered himself with tattoos, and died and went to hell. Tragic, and so easily avoidable.

I never managed to get to Page 13 of Big Daddy, which is what we really need; link (if it works for you) here. It didn’t work for me, but you’ll find a description of the contents by someone called Honus at talkorigins, and I’ve seen some of the relevant cartoons reproduced elsewhere. So you can either take Honus’s and my word for it, or go online to Chick Publications and buy 25 copies (minimum purchase) of the tract, which I am not about to do.

The really remarkable thing about the tract is that it actually gives the primary literature references to the results that is discussing. And the briefest perusal of this primary literature will show why the papers that Chick refers to, far from undermining radiometric dating, actually reinforce it.

That snail was not 3000 years old, but that really was its apparent radiocarbon age, because it was exchanging calcium carbonate in its shell with mineral calcium carbonate. And that makes all the difference, so you need to take such features of the environment into account.

Many readers will be familiar with the principle of carbon-14 dating. Carbon-14 decays with a half-life of 5730 years. Nonetheless, the fraction of carbon-14 in the atmosphere stays roughly constant (or did before we started adding to it by nuclear weapons testing, and diluting it with carbon dioxide from fossil fuels). That is because the upper atmosphere is bombarded with cosmic rays, which cause nuclear reactions that convert nitrogen-14 (stable) to carbon-14. Mixing distributes this radiocarbon through the atmosphere, where it is taken up by plants and, in due course, animals. As long as you are alive, you are part of the circulating pool of carbon, but as soon as you die, the carbon-14 in your body starts decaying. Of course, cosmic ray intensity is not really constant over a long period, but we can calibrate carbon-14 dates by comparison with carbon in tree rings (dendrochronology). The tree ring correction is small for most purposes, but matters for things like precise dating of Egyptian dynasties.

The point, of course, is that the carbon in the lettuce being fed to the snails is part of the general pool, but the carbon in calcium carbonate minerals is radiochemically dead, having been out of circulation for a long time. What the paper really showed was that the snail exchanges carbonate in its shell with carbonate from dissolved minerals, giving a spurious depletion of radiocarbon in the snail. You will find the story in Science, 1963, p. 637 (paywall, sorry, but summary here).

What about these rocks in Hawaii? Here again the paper is behind a pay wall, but if you follow this link it will take you to the title and abstract, which is all you need. In fact, the title alone is all you need: “Radiogenic helium and argon in ultramafic inclusions from Hawaii”. Inclusions. And in case that’s not clear enough, the abstract tells you that the work is all about the dating of xenoliths. Xeno- foreign, as in xenophobia; lith rock, as in monolith. Look at the paper in more detail, if you can get access to it, and you will find that the excess argon is only found in bubbles of fluid within the rock, that bits of rock that aren’t bubbly don’t show any, and that there is circumstantial evidence that the argon comes from deep within the Earth’s mantle, not radioactive decay in the lava itself.

Anomalies happen all the time in geology. They are, in the original sense of the expression, exceptions that prove the rule; if there were no rule, we would not consider them exceptional. Uranium-lead and potassium-argon dates of rocks usually agree, but not if the rock has been so strongly heated that argon gas can escape. Whole rock dates can be misleading, as in the example of the Hawaiian volcano, if the rock has been contaminated from some source, in this case fluid from the mantle. So far from undermining the method, these anomalies add further information about the sample. In much the same way, radiocarbon dates will be anomalous if some of the carbon comes from inorganic sources, as in the case discussed above, and the anomaly might even be used to tell us something about the specimen’s history and diet.

Now here’s the bit that I really don’t understand. What is going on in Jack Chick’s mind, when he gives us this stuff? I assume that he is an honest person of goodwill, who is doing his best. He really believes that because I and most readers here accept the fact of evolution, we are going to be punished in hell for ever. Being a kindly man, he really doesn’t want that to happen, so he is doing his very best to convince us of the error of our ways.

So why does he do it by pointing us towards papers that say the very opposite of what he says they say? I can only speculate that this is the result of what psychologists call confirmation bias, which leads to interpreting new information, however perversely, in a way that supports what you already think. And when we come to creationism, the motivation for bias is extreme. Remember that we are talking about people who really believe (a) that if you don’t accept salvation through Jesus you are going to go to hell, and (b) that the doctrine of salvation through Jesus only makes sense if the biblical Fall is a historical fact. The papers I’ve mentioned above show that under certain rather special circumstances, radiometric dating will give you the wrong answer unless you take those circumstances into account. Young Earth creationists, knowing that their entire worldview depends on refuting radiometric dating, pounce on these examples as evidence that the method is unreliable. Which of course it is, if you don’t do it right. So what?

All of which gives me uncomfortable pause for two reasons. If creationists are so blinded by confirmation bias, what hope is there of reasoning with them? And if I see my intellectual opponents displaying confirmation bias, completely oblivious to what they are doing, what makes me think that I am any different?

IncredibleCrib sheet: Definition as obfuscation. Misdefinition of science to exclude all indirect inference (although even Young Earth creationists accept the fact of an Ice Age on geological evidence). Macroevolution, if the word means anything, means major change, and this takes more time than we have been watching. So of course we’ve never seen it. Similar fossils do indeed imply similar ages, but the order of these ages has been known for nearly 200 years on the basis of stratigraphy, and absolute ages established for over 100 years now by radiometric dating. Polystrate fossils were explained in 1868; the explanation is much the same today. New Scientist really did point out in 1997 that it is silly to carry on using Haeckel’s highly questionable drawings, as some still do, when we now have a much more detailed information. But, as explained in Alice Roberts’s Incredible Unlikeliness of Being and many other places, the gill folds on the human embryo really are homologous to the folds on that of a fish. They just develop rather differently, explaining such oddities as the tortuous path of our vagus nerves. As for the whale’s pelvis having “nothing to do with walking on land”, by 1999 we already had extensive series of fossils linking whales to their terrestrial ancestors; there is an excellent review here by one of the scientists involved in Evolution Education and Outreach (free download), and whales evolution also features in an excellent video here . The development of secondary functions (exaptation) is commonplace. Thus mammals’ ear bones are vestigial relics of reptiles’ rear jawbones. Creationists often argue, as here, that natural selection can only remove, and not add. This riddle was solved 120 years ago, with the discovery of mutation. Mutations supply novelty; selection winnows it. Creationists agree in explaining away pre-modern human fossils, such as Lucy and numerous others already known by 1999, as being either apes, or humans. Unfortunately, they can never agree on which is which. And, something that I think believers in particular should find offensive, the theological absurdities of the final frame.

Update on Grandmother Fish, and more to come

Grandmother Fish will be released in the US on September 6, and in the UK on October 13, by Feiwell and friends. That’s a division of Macmillan, like the Nature group who now also publish Scientific American. Good company, well deserved (full review here).

And more to come  from the same author-illustrator team; Clades, an animal-matching game with rules based on the underlying science.

Your chance to get involved: Kickstarter starts October 17th. Preliminary details in the August 15th entry on the Grandmother Fish Facebook page.


Why is this game important? Because of the one sentence in the book that I would strongly disagree with: “Evolution by natural selection is very difficult to understand because it doesn’t make intuitive sense.” I think that the main reason people think it is difficult is because there is an booming cottage industry in disinformation about evolution, and that the idea of clades, relationships through common descent, will make perfect intuitive sense to children who are, after all, familiar with exactly this in their own families.


Disclosure: I made some suggestions to Jonathan about family relationships among mammals. Which are actually quite difficult to sort out unambiguously, because of rapid radiation among placentals. So if anything in the family tree turns out to be wrong, the fault may well be mine.


And much more information for the adults (and, soon enough, the children):


And finally, a useful list of common misconceptions and how to correct them – but if you want to see that (and I hope you do), then buy the book for yourself.

Or for your grandchildren.

These laws, taken in the largest sense, being Growth with Reproduction; inheritance which is almost implied by reproduction; Variability from the indirect and direct action of the external conditions of life, and from use and disuse; a Ratio of Increase so high as to lead to a Struggle for Life, and as a consequence to Natural Selection, entailing Divergence of Character and the Extinction of less-improved forms…
