Brag time: My “Slam Dunk to Creationists” attacked by Discovery Institute

The Discovery Institute, self appointed spokesman for Intelligent Design theory (i.e. cryptocreationist obscurantism) has singled out my piece in The Conversation, How to slam dunk creationists when it comes to the theory of evolution.

My piece argues that we should be talking about the evidence, not about the meaning of words. In particular, I take exception to the National Academy of Sciences definition of a theory as “supported by a vast body of evidence”, on the grounds that calling something a theory tells us nothing about how well supported it is. The Discovery Institute uses fancy layout to quotemine what I said, so that my criticism of the National Academy is made to look like approval, before taking exception to the National Academy of Sciences definition of a theory as “supported by a vast body of evidence”, on the grounds that calling something a theory tells us nothing about how well supported it is.

In passing, the DI also tells us that “Sahelanthropus … is thought by some to just be a female gorilla.” Eat your heart out, Smithsonian.

I’m honoured by such well-informed and well thought out attention. And while the DI’s article is unsigned, connoisseurs of Creationism will understand my additional delight at having Casey Luskin and Douglas Axe listed among my accusers. With enemies like this, who needs friends?

At the time of writing, my piece has attracted 78,000 hits [update: 95,000 hits] and been featured by Newsweek, Business Insider, The Raw Story, RealClearScience, and others. My thanks to Jane Wright, at The Conversation, whose skilful editing helped make all this possible.

Creationist nonsense on geology; the odd case of Prof McIntosh D.Sc.

Image result for andy mcintoshCatastrophism versus gradualism; this controversy was laid to rest by TH Huxley in his 1869 Address to the Geological Society, but UK Young Earth Creationists persist in parading the corpse as if it presented a living challenge to current thinking. Perhaps it appeals to their absolutist binary mindset.

McIntosh himself is a member of the group mendaciously mislabelled Truth in Science, which distributed the equally mendacious neo-creationist tract Exploring Evolution to UK schools some years ago, and is an author of the error-saturated Origins, Examining the Evidence, published by that group. BCSE has published a detailed review of Exploring Evolution here.

This piece by my friend, the geologist historian Anglican priest Michael Roberts, will tell you more about McIntosh’s writing than you wish to know, but will convey a wealth of fascinating geological and historical information in the process.

THE GEOLOGY OF GENESIS FOR TODAY

Image result for andy mcintosh

One of the best selling British creationist books is Genesis for Today by Andy McIntosh, which is now in its 5th edition. https://www.dayone.co.uk/products/genesis-for-today

Most of the book is a popular exposition of Genesis 1 to 11 – and some of it I agree with, but not his insistence that it is literal history.

In Genesis for Today McIntosh gives three scientific appendices, which are much the same in the 1st and 5th editions.  I could either go through and nit-pick his geological errors or consider them under main headings. I have chosen the latter.

Most would think that a professor in a scientific discipline at a leading university (with a first-rate geology department) would be able to make a reasonable showing on geology.Many amateurs and non-geologists I’ve met in geological societies have a clear grasp.

Science matters because it works (but it’s not quite that simple)

Reblogged from The Logic of Science, but with this comment: No one would disagree with these claims on behalf of science, and and that’s the problem.

The climate change denialists, like the smoking science denialists before them, pretend that the science is unsettled. The creationists prattle of “creation science” and “flood geology”. The extremely able and intelligent US Vice President, pandering to his creationist base, did not claim to be anti-science. On the contrary, he used the very fact of a major scientific discovery (Sahelanthropus, evolution, and the word “theory”; what Mike Pence really said) to blur the distinction between the established core and the fast-changing frontiers. And if we are to effectively defend science, we need to understand the emotional appeal of the ideology that leads to the rejection of vaccination, medicines, and GMOs, and to the prejudging of complex arguments in such cases as fracking and nuclear power.*

We need to think very carefully about tactics. If we seem to be saying anything like “Science is a good thing, therefore you should trust the scientists”, we are playing into the hands of our enemies. We are right to demonstrate and protest when science is denied, or ignored,  or muzzled.  And yet people (that’s all of us) believe what they want to believe.  The task  then is, how to persuade people to want to believe  in the evidence?

*This last comment cuts both ways, of course

The Logic of Science

Why should you support science? Because it works! It’s crazy to me that I even have to say that, but this is where we are as a society. Various forms and degrees of science denial are running rampant throughout our culture, and attacks on science are being disseminated from the highest levels. Indeed, it has gotten to the point that hundreds of thousands of scientists and science enthusiasts like myself feel compelled to take to the streets to march for science and remind everyone of the fundamental fact that science works and is unparalleled in its ability to inform us about reality and improve our world.

Express science reporter: “proof dinosaurs lived with HUMANS?”

“Is this proof dinosaurs lived with HUMANS? Creationist claims REAL truth COVERED UP”

The Express, an ostensibly serious right wing UK newspaper, reports under “SCIENCE”.

dinosaur

Express caption” “Did dinosaurs co-exist with humans?”

The evidence? A display at Ken Ham’s Creation Museum. Ham is quoted as saying that the standard scientific evidence is a coverup, as his own dinosaur fossils show, for some unstated but presumably non-standard reason:

“Ken Ham, founder of Creation Museum in Kentucky, United States, has put the supposed evidence on display at his centre. Standard scientific evidence shows dinosaurs died out 66 million years ago … and the anatomically modern man did not emerge until around 200,000 years ago. But Mr Ham believes this is a cover-up … the dinosaur fossils were found in Colorado about a decade ago and seem to represent a tyrannosaurus rex [sic].”

Express caption: Scenes might have been similar to Jurassic Park

(Fuller quotations supplied by the Sensuous Curmudgeon, here)

Ham complains that evolutionists “use dinosaurs … to promote their worldview”. How dare they! But do not accuse the Express of bias. It does refer to what it calls “the  standard scientific evidence”, and they do quote two sentences from Bill Nye, before showing the image on the right:

And compared with the image below, the paper’s front page in the runup to the Brexit referendum, the dinosaur story is factually balanced reporting reporting; fake news is not the invention of the Trump campaign.

@hendopolis: SUNDAY EXPRESS: 12m Turks say they’ll come to UK #tomorrowspaperstoday #bbcpapers https://t.co/ArvI3hlgc2

The Express group is wholly-owned by Richard Desmond, a UK billionaire and former publisher of such informative periodicals as Penthouse and Asian Babes. circulation is close to 400,000, in addition to online readership. In 2002, Desmond made a £100,000 donation to Blair’s Labour Party, but in 2004 switched allegiance to the Conservatives.

The lead story of this post would seem to be based on the February 4 2014 debate between Ken Ham and Bill Nye, which did so much to restore the former’s finances. Why it should have resurfaced now in the Express, I have no idea. But it does concern me. Desmond does not make a habit of backing longterm losers.

My “Islamic Foreshadowing of Evolution” has appeared in Muslim Heritage.

I am published in Muslim Heritage.

Islamic Foreshadowing of Evolution (full article here).

Gloriously illustrated by the Muslim Heritage editorial team; so much for the common impression that Islam forbids representational art.

Images assembled by Muslim Heritage editorial team

I briefly describe present-day evolution science, and why the evidence for this is considered overwhelming, having earned endorsements from national academies worldwide, including the academies of several predominantly Muslim countries.

I show how Muslim thinkers (especially Al Biruni and Ibn Sina) went beyond Aristotle’s mere assertion that the Earth is old (for Aristotle, infinitely old), by observing and discussing fossils and sediments in an unmistakably scientific manner. I also discuss widespread claims that Islamic scholars had anticipated modern evolutionary thought, and come to the sad conclusion that these are not warranted. What is being described, by sources as diverse as the poet Rumi, the Ikhwan al-SafaI (Brethren of Purity, 8 – 10 C CE), and the pioneer social scientist Ibn Khaldun in 1377 CE, is the Great Chain of Being, derived from Aristotelian thought, and represents stages of development, but does not imply common descent, or change over time. I also look at the claims made on behalf of al Tusi, but fear that these will not stand examination.

The one clear example that I do find of anticipation of the central ideas of mutability of species and common descent comes from al Jahiz’s delightful Kitab al-Hayawan (Book of Living Things, 9 C CE), where among much other interesting material (though the story of birds cleaning crocodiles’ teeth is, alas, suspect) he correctly suggests common ancestry for wolves, dogs, and foxes.

I would be delighted to hear of other examples, provided these are accompanied by links to reliable translations (I regret that I cannot read Arabic or Persian) of the original material. I am of course aware of a great deal of twentieth and twentyfirst century literature that makes such claims, but on examination I have so far found these to be simply back-projection. We must also remember that earlier thinkers must be judge in the context of their own times, that they were unaware of the significance that observations would require at a later stage, and that to judge them according to how well they happen to agree with us, with our vastly expanded knowledge base, is unhistorical and, indeed, patronising.

On the relationship between evolution and Islam, I have this to say:

It is not my place to discuss this. I will merely point out that debate between those who accept and those who reject evolution can be found within all the Abrahamic religions, with discussion hingeing on the ways in which the ancient sacred text should be interpreted by a modern reader (Marwa Elshakry, of Columbia University History Department gives a scholarly account1). There are those who protect traditional interpretations by rejecting evolution, but such rejection carries a high cost since it creates a conflict between faith and worldly knowledge. And there are those who attempt to evade this conflict by denying the plain scientific facts; here the cost is even higher. There was a recent vigorous discussion of these topics organized by the Deen Institute,2 and the scientific academies of Bangladesh, Egypt, Indonesia, Morocco, Pakistan, Palestine, Turkey and Uzbekistan have joined others worldwide in affirming evolution.3

On the Muslim Heritage Facebook page, my article has received over 2000 “likes”. I am grateful to the editorial staff of Muslim Heritage for inviting me to contribute this article, and to Ehab Abouheif, Jim Al-Khalili, Glenn Branch, J. E. Montgomery, Cem Nizamoglu, Rebecca Stott, and Douglas Theobald for helpful discussions.

I will be posting a fuller summary of my rather lengthy article in due course.

The Little Puddlian Philosophical Society and the Fine Tuning Argument

Puddle theory, according to Wikipedia, is “a term coined by Douglas Adams to satirize arguments that the universe is made for man. As stated in Adams’s book The Salmon of Doubt:

“imagine a puddle waking up one morning and thinking, ‘This is an interesting world I find myself in, an interesting hole I find myself in, fits me rather neatly, doesn’t it? In fact, it fits me staggeringly well, must have been made to have me in it!’ This is such a powerful idea that as the sun rises in the sky and the air heats up and as, gradually, the puddle gets smaller and smaller, it’s still frantically hanging on to the notion that everything’s going to be all right, because this World was meant to have him in it, was built to have him in it; so the moment he disappears catches him rather by surprise. I think this may be something we need to be on the watch out for.”

I yield to no one in my admiration for Douglas Adams, and admire here in particular his reminder that our place in the Universe may really be rather precarious. However, on this occasion he had been anticipated. Read the rest of this entry

Genetics provide powerful evidence of evolution

An excellent survey from The Logic of Science, with striking examples. At every level of detail, the family trees inferred from morphology match the trees established by molecular biology.

The Logic of Science

Many people are under the false impression that evolution is just a guess or a belief, when in reality, it is one of the most well-supported concepts in all of science. The evidence for it is overwhelming and comes from many different disciplines such as paleontology, comparative anatomy, biogeography, and perhaps most significantly, genetics. Indeed, modern genetic tools have allowed us to repeatedly test evolution’s predictions, and those predictions have consistently come true. Therefore, I am going to explain in simple terms what the genetic evidence is and why it is so compelling. As I will show, the evidence perfectly matches the predictions that the theory of evolution made decades before we could test those predictions. Further, the patterns do not make sense if our modern organisms were specially created, because there is no reason why a creator would have had to make life with these patterns. In other…

Evolution is not progress

Evolution has nothing to do with progress. Most evolution doesn’t even have anything to do with adaptation, and it is perfectly possible for a change that is worse than useless to spread through a population. Paradoxically, however, such non-adaptive change may be a necessary prelude for major adaptations.

This post was inspired by a recent opinion piece (open access here1)  in BMC Biology, entitled “Splendor and misery of adaptation, or the importance of neutral null for understanding evolution” (I will explain what “neutral null” means later). The paper itself is in parts highly technical, with 86 references to the original scientific literature, but I will try here to give a general overview of some of the main conclusions, and to place them in context.

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

Darwinstree

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.
