Assam Earthquake 15th August 1950

From my friend Michael Roberts. And next time anyone tells you that fracking causes earthquakes, ask them what magnitude and refer them to the diagram at the end of this post.

Peddling and Scaling God and Darwin

As we mark the 70th anniversary of India and Pakistan, we would also remember that the Assamese did not have a good day on the 15th August.

During the night a massive Mag 8.6 earthquake struck the area, with its epicentre just inside Tibet.That makes it far bigger than the Mag 7.8 in Nepal in 2015. However the damage or loss of life, though considerable, were far less as the area was less densely populated.

My own interest is that we were living in Jorhat on the tea plantations of Assam at the time and the quake became part of family history. We lived in a bungalow, which was built on stilts for protection against earthquakes and had about ten servants as was the norm.

So what happened?

The bungalow on stilts began to sway. Wardrobes fell over, but didn’t hit anyone.

How to kill the dinosaurs in ten minutes

Ten minutes difference, and Earth would still be Planet of the Dinosaurs

Ammonites Haeckel

Not only vertebrates, but ammonites, marine molluscs, perished in the disaster. Image (Haeckel, 1904, via Wikipedia). Click on this and other images to enlarge

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

Darwin’s Boulders

From my friend the Rev Michael Roberts. How Buckland and then Darwin, exploring in Wales, came to accept Agassiz’ Ice Age theory, with Michael’s own stunning images of locales. And no kittens, I’m afraid, but a field assistant [sic] dog

Peddling and Scaling God and Darwin

In June 1842 Charles Darwin undertook his last geological field trip. He was at his father’s house, The Mount  in Shrewsbury, that month and after a winter of sickness, he felt somewhat better. Thus, he went in his gig to Snowdonia to assess whether Buckland was correct in identifying proof of a former Ice Age. In October 1841 William Buckland travelled to Wales with Thomas Sopwith (his grandson designed the Sopwith Camel, a WW1 fighter plane) to see whether Agassiz could be right about a former Ice Age. In a few days of horrendous Welsh weather Buckland identified all the main glacial troughs

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.

One of the best selling British creationist books is Genesis for Today by Andy McIntosh, which is now in its 5th edition.

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.

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.

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 things 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.

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…

…Evolution, once a theory in crisis, is now in crisis without even a cohesive unifying theory.
