Ten minutes difference, and Earth would still be Planet of the Dinosaurs
We have suspected for some decades that the dinosaurs1 became extinct as the result of a massive meteorite, an asteroid, hitting the Earth. We have known where the impact site was since 1990, if not before. But it is only last year that we successfully drilled into the impact site, and only now, for the first time, do we really understand why the impact was so fatal. And if the meteorite had arrived ten minutes earlier, or ten minutes later, it would still no doubt have inflicted devastation, but the dinosaurs would still be here and you wouldn’t.
66.1 million years ago, dinosaurs covered the Earth. 66 million years ago, there were none. And not only the dinosaurs, but the pterosaurs in the skies, the long necked plesiosaurs and even the ammonites in the oceans, and 75% of all complex animal life. No terrestrial vertebrate heavier than around 25 kg seems to have survived. What happened? Read the rest of this entry
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.

“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”.
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].”
(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.
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.
“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
The now Vice-President of the United States stands accused of having said that evolution is “just a theory”; see here and here. No he did not say that. What he did say (full text below, with notes) was far, far worse. Much more detailed and much more dangerous.
L: Pence being sworn in as a member of the House Education and Workforce Committee (CNN)
After reminding us that he was trained in law and history, he mangles the historical facts and legal significance of a key court case (the Scopes trial).
By quotemining a secondary source,* which he treats as if primary, he twists the then-recent discovery of Sahelanthropus into an argument against the underlying science. It is changeable, he argues, therefore it is uncertain.
He justifies this manoeuvre by harping on the ambiguous word “theory”, and making a falsely rigid distinction between theory and fact.

And worst of all, he asks his colleagues to “demand [emphasis added] that educators around America teach evolution not as fact, but as theory”. The proponent, when it suits him, of small Government wants Washington to tell teachers how to teach.
Pence has been accused of stupidity because of the factual and logical errors contained in his speech. On the contrary, Read the rest of this entry
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
Trump’s Education Secretary Nominee DeVos Should Challenge Darwinism* – David Klinghoffer, CNS, 13 January 2017 
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.

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 things are important.
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.
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…

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.
This incredibly duplicitous meme appeared on my twitter feed today. Fri 13th Jan 2017
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…

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.
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…
