Can we trust radiocarbon dating?

Willard Frank Libby, inventor of the method

Can we trust radiocarbon dating? Young Earth creationists tell us that we can’t. After all, it makes the same range of assumptions as other radiometric dating methods, and then some. Other methods benefit from internal checks or duplications, which in the case of radiocarbon dating are generally absent. There are numerous cases where it appears to give absurdly old ages for young material, while apparent ages of a few tens of thousands of years are regularly reported for material known on other evidence to be millions of years old. So can the Young Earth creationist1 objections be rebutted, and if so how?

The principle of radiometric dating is simple.2 If we know how much of a particular radioactive substance was present when a material formed, how much is still there, and Read the rest of this entry

The Case Against Evolution – turning Chick on its head!!

From Old Earth Ministries by way of my friend Michael Roberts. Covers the scientific bases clearly and comprehensively, before exposing the contorted theology of Young Earth Creationism, and the arrogant presumption of its claim that evolution is incompatible with Christianity.

Disclosure: I see difficulties with religious beliefs, but these are not increased (perhaps the contrary) by our knowledge of evolution, and since they are not my difficulties it is not my place to comment on them, other than to point out that the YECist claim to “own” Christianity (or any other religion) is plainly false

Intelligent Design or intricate deception? What I told students during the Kitzmiller trial

Dec 20 is the anniversary of the Kitzmiller decision, an early Christmas day present for science and common sense. But when I first wrote here “Judge E. Jones III’s ruling is … unlikely to be challenged unless at some later date the US Supreme Court acquires a creationist majority”  I had not foreseen a creationist Vice-President. Take nothing for granted.

Primate's Progress

Unt The University of North Texas, where I was teaching in 2005

Kitzmiller v Dover Area School District, in which judgment was pronounced on 20th December 2005, is the court case that established that Intelligent Design is not science, but a form of religiously motivated creationism, and as such may not be taught in publicly funded schools in the US.This is a shortened version of what I told the students at Texas Academy of Mathematics and Science, University of North Texas’s early admissions programme, whom I was privileged to be teaching at the time of the trial. I have omitted my discussion of the embarrassing Intelligent Design pseudotext, Of Pandas and People, and the even more embarrassing statement that the Dover School Board instructed teachers to read, for reasons of space and because I have discussed them here before.  I have tried to avoid rewriting in…

If you are interested in evolution, get this book

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.

Oxf-uni-mus-nhL: The Oxford Museum of Natural History, where the event took place. Click on this and other images to enlarge

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.

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

UK Conservatives, meet the DUP: extremist, creationist, sectarian

“Our MPs will be the kingmakers, playing a huge role” (R: Gregory Campbell MP, from whose victory speech those words are taken)

Overview: I am assuming as I write this that the Conservative Party will remain in power in the UK for the immediate future. As a matter of arithmetic, this will require the cooperation of the Democratic Unionist Party. All this may, however, change at any time.

Update on the Orange Walk issue: it’s already happening: “Supporters of the Democratic Unionist Party (DUP) are demanding Theresa May allow a banned loyalist march as part of an agreement by the Northern Irish party to prop up a minority Conservative government.” Independent, Monday 12 June

Kingmakers. There is no doubt that this is how the Democratic Unionist Party (DUP) see themselves. And there is no doubt that they aim to exploit this role to the full. Not by formal coalition, the trap  into which Nick Clegg so disastrously led his party in 2010, but “confidence and supply”, which will leave them free to make new demands and to threaten to withdraw support at any time. I will not attempt to unravel the complex affairs of Northern Ireland, but with the settlement there more fragile than it has been for some years, the strengthening of one partisan faction must be a matter of concern. Anyone requiring evidence of the DUP’s ruthless political infighting, inflammatory rhetoric, and skill at reopening old wounds is invited to visit their web site at

Saint Johns College, Cambridge, where Nigel Dodds studied law

Nor should we fall into the trap of underestimating the DUP intellectually because of the crudeness of their dogmas. Nigel Dodds, of whom much more below, has a first-class honours degree in law from Cambridge University, while Ian Paisley Jr., MP for North Antrim and son of the charismatic Reverend Ian Paisley who founded the party, holds BA (hons) and MSSc degrees from Queen’s University Belfast in History and Irish Politics.

Sectarianism and links to violence: The DUP is a sectarian party, founded by former members of the UUP (United Unionist Party) who considered that party’s leadership too conciliatory towards the large Republican (i.e. Catholic) minority. In the late 1980s and 1990s, there were strong links between the DUP and Protestant paramilitary groups Read the rest of this entry

The “scientific method”, a needless stumbling block. With a note on falsification

Science does not have a separate special method for learning about the world, the “scientific method” as taught in schools is a damaging illusion, and the falsifiability criterion has itself been falsified

Below, R: How not to; “The Scientific Method”, as inflicted on Science Fair participants. Click to enlarge

Consider this, from a justly esteemed chemistry text:

Scientists are always on the lookout for patterns.… Once they have detected patterns, scientists develop hypotheses… After formulating a hypotheses, scientists design further experiments [emphasis in original]

Or this, from a very recent post to a popular website:

The scientific method in a nutshell:
1. Ask a question
2. Do background research
3. Construct a hypothesis
4. Test your hypothesis by doing experiments
5. Analyze your data and draw conclusions
6. Communicate your results [emphasis in original]

Then, if you find yourself nodding in agreement, consider this:

Since a scientific theory, by definition, must be testable by repeatable observations and must be capable of being falsified if indeed it were false, a scientific theory can only attempt to explain processes and events that are presently occurring repeatedly within our observations. Theories about history, although interesting and often fruitful, are not scientific theories, even though they may be related to other theories which do fulfill the criteria of a scientific theory.

If you are familiar with the creation-evolution “controversy”, you may well suspect that last example of being so much creationist waffle, intended to discredit the whole of present-day geology and evolutionary biology. And you would be right. This quotation is from Duane Gish, a major figure in the twentieth century revival of biblical literalist creationism, writing for the Institute of Creation Research.1

L: Mike Pence, ” [N]ow that we have recognised evolution as a theory… can we also consider teaching other theories of the origin of species?”

Such nonsense isn’t funny any more, if it ever was. The man who may very soon find himself President of the United States is an eloquent spokesman for creationism.

And yet Gish’s remarks seem to follow from the view of science put forward in the first two excerpts. What has gone wrong here? Practically everything. Read the rest of this entry
