EVOLUTION: What the Fossils Say and why it Matters, Donald R. Prothero (2nd edition)

If you are interested in evolution, get this book. And make sure that your library gets it. And your children’s highschool library. Incidentally, it’s incredible value; list price $35.00/£27.95 from Columbia University Press, with over 400 lavishly illustrated pages.

The book is a comprehensive survey of the fossil record, supplemented at times with other evidence, and framed as one long argument against creationism. It opens with a general discussion of the ideas behind current evolutionary thinking, moves on to a survey of specific topics in (mainly animal) evolution, from the origins of life to the emergence of humanity, and concludes with a brief discussion of the threat that creationism poses to rational thinking. The argument is laid out clearly in the seemingly artless prose of an accomplished writer in love with his subject matter, with plain language explanations that presume no prior knowledge, while the detailed discussions of specific topics give enough detail to be of value, I would imagine, even to a professional in the field. The author is an experienced educator and researcher, with thirty books ranging from the highly technical to the popular, some 300 research papers, and numerous public appearances to his credit, and the work is copiously illustrated with photos, diagrams, and drawings by the author’s colleague, Carl Buell. These illustrations are an integral part of the work, graphically displaying the richness of the data at the heart of the argument. Read the rest of this entry

What the Bishop said to the Biologist; a Victorian scandal revisited

Yes, Bishop Wilberforce really did ask TH Huxley, “Darwin’s bulldog”, whether he would prefer an ape for his grandfather, and a woman for his grandmother, or a man for his grandfather, and an ape for his grandmother. And Huxley really did say that he would prefer this to descent from a man conspicuous for his talents and eloquence, but who misused his gifts to ridicule science and obscure the light of truth. This and more at the very first public debate regarding Darwin’s work on evolution, only months after the publication of On the Origin of Species.

The debate took place at the May 1860 meeting of the British Association for the Advancement of Science. The actual exchange is whitewashed out of the account of the meeting in the gentlemanly Athenaeum, leading some historians to wonder whether it really occurred, but a recently rediscovered contemporary account places the matter beyond doubt. What I find even more interesting, however, is the way in which argument and counter-argument between Wilberforce and Huxley, and between other supporters and opponents of the concept of evolution, prefigure arguments still being used today.

Evolution Before Our Eyes: Complex Mutations in Microbes Giving New Functions

I cannot improve on this excellent survey, with its refutation of the creationist’s crucial denial that evolution generates new functional information; the most I can do is help publicise it.

How to learn from creationists

“The wise learn from everyone.”1 The freak success (half a million reads) of my recent piece How to slam dunk creationists, and the subsequent discussion, have again set me thinking about how to learn from creationists. It is not enough to say, as Dawkins notoriously said, “[I]f you meet somebody who claims not to believe in evolution, that person is ignorant, stupid or insane (or wicked, but I’d rather not consider that).” Conversation is a two-way street, I have certainly learnt from creationists’ attacks on evolution, and if I am learning from them it is at least possible that they are learning from me.

Types of comment

Comments I have had from creationists fall into three broad groups (and note that contrary to what Dawkins says, some of these are at least partly informed, highly intelligent, and completely rational):

1) Simple misstatements

2) Appeal to the Bible

3) Purportedly scientific arguments, some without merit, while others refer to important issues.

From simple misstatements, not very much can be learnt, except perhaps the source of the misinformation. Remember that if someone quotes wrong information, the burden of proof is not on you but on them. Leave it there, as in this actual exchange: Read the rest of this entry

What do Christians really believe about evolution?

Most people in the UK think that religious people believe in six-day creationism. Fortunately, they are wrong.

Less than one in six UK believers prefer separate creation to evolution

Lucas Cranach d. Ä. 035

The Garden of Eden (Lucas Cranach the Elder (1530)). Note scenes including the creation of Eve, the temptation by the serpent, and the expulsion

A new YouGov poll conducted in Canada and the UK shows two contrasting facts. Among those who call themselves “believers or spiritual”, only 16%, under one in six, rejected evolution in favour of separate creation. A much larger group (39%) thught that “Humans and other living things evolved over time, in a process guided by God”. As an advocate of evolution science, I regard such people as potential allies. “Guided by God” is so vague an expression that it could be taken to include God having set up the laws of nature, which was actually Darwin’s own position, according to his autobiography (here, pp 92-3), when he wrote Origin of Species. (Caveat: the options offered were

  1. Humans and other living things were created by God and have always existed in their current form
  2. Humans and other living things evolved over time, in a process guided by God
  3. Humans and other living things evolved over time as a result of natural selection, in which God played no part
  4. I have another view of the origin of species and development of life on Earth which isn’t included in this list
  5. I don’t know / I do not have a view on the origin of species and the development of life on Earth

On learning that the Iraqi government is dropping evolution from schoolbooks

This is how I appeared on Arabic-language Science News, أخبار العلوم – Science News, after a Facebook friend translated my remarks into Arabic

Teaching biology without mentioning evolution is like trying to teach chemistry without mentioning atoms. If you deny evolution, you have to deny the entire fossil record and also all the evidence of molecular biology. And evolution has nothing to do with religion. Within all the world’s great religions, there are thinkers who accept the evidence for evolution, and regard evolution itself as one of God’s creations. We do not allow scientists to tell religious leaders how to teach religion, so why should we allow religious leaders to tell scientists how to teach science?

Commenting on the recent decision by the Iraqi government to remove evolution from the school textbooks, I wrote these words to one of my many new-found Iraqi friends [1], a young man in Mosul now able to speak his mind after three years of Isis suppression; he then quoted me on Arabic-language Science News, أخبار العلوم – Science News, which has led in the first 12 hours to a brisk correspondence, more than a thousand likes, over fifty shares, and some not always friendly commentary in which chimpanzees feature prominently in my own assumed ancestry. I can only express my admiration for someone who, sheltering somehow in the ruins of that city, finds time to think of such things.

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.

Slam Dunk image plagiarised from Discovery Institute. Provenance unknown

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.

From the whole of his book, other writings and…

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.
