Von Daniken makes an embarrassing error about chimp-human difference and more...

chimp-human difference: 83% ???

In a previous blog I gave a first impression of Von Daniken's book Evolution is Wrong. A Radical Approach to the Origin and Transformation of Life. I noticed some funny and nice things and some problems. I now finished a complete review of the book which I published on my Was Darwin Wrong website. I found a huge blunder: Von Daniken misreads a scientific publication about genetic differences of chimp and human. Further, a lot of amazing logical fallacies. These give entertaining reading and show how a non-scientist and non-biologist thinks about biology and evolution. Evolution educators could learn from this and overcome intuitive and non-religious conceptual obstacles to understanding evolution. Evolution textbook writes should also include a section 'Overcoming obstacles to evolution'.


Notes

An example of paying attention to conceptual obstacles is: Kostas Kampourakis (2014) 'Understanding Evolution'. The obstacles for Von Daniken are not (yet) included.

New evolution textbook as birthday present for Darwin

 

EVOLUTION
Futuyma, Kirkpatrick 5th ed. OUP hardback 2023
615 pages plus 83 pages index, literature.

A new evolution textbook for Darwin's birthday 12 Feb 2023

The publication of a new evolution textbook is a rare event. The textbook displayed above is now the most recent evolution textbook. The previous edition (4th) was also published together with Mark Kirkpatrik in 2017 (5 years ago). It is the longest-running series of Evolution textbooks. Futuyma published his first evolution textbook in 1979. For a visual overview of all evolution textbooks see the homepage of my WDW website. And here on the Introduction page they are listed with short descriptions.

The emphasis of this textbook is on organisms and species. Human evolution gets considerable attention (50 pages). The largest section is about mechanisms: mutation and variation, natural selection, genetic drift. There is a large section devoted to the History of Life (122 pages). I like the presence of a chapter about genome evolution. There is some attention to philosophical issues, and a chapter about Evolution and society. The numerous color illustrations make it a pleasure to browse. 

I was mystified and disappointed that there was no illustration of the molecule all life is based upon; the carrier of hereditary information. This molecule and its mechanisms of action are described in as few words as possible. As if this molecule is of minor importance in evolution. However, its discovery was rewarded which a Nobel prize! I am talking about DNA. Portraits of many evolutionary biologists are present, but Watson and Crick are missing. I also found the space devoted to the origin of life minimalistic.

A welcome feature of this edition is that most chapters have a final What We Don't Know section. The message is: evolutionary biologists have not yet solved all evolutionary puzzles. Critics take note!

 

I will update this first impression either here or on my WDW website.

Erich von Daniken (2022) 'Evolution is Wrong. A Radical Approach to the Origin and Transformation of Life'

Erich von Daniken (2022)
'Evolution is Wrong'

I was curious what Erich von Daniken's arguments against evolution are, and how good his knowledge and understanding  of evolution is. Surprisingly,  he gives a reasonably accurate but short account of the discovery of DNA. 

He even mentions Phoebus Levene [4], but writes that Levene used a 'supermicroscope' and that later his discoveries were confirmed with an electron microscope (wrong). He accurately but incompletely describes Chargaff's discoveries and also that Watson & Crick's double helix model was based on Chargaff. Unfortunately, Von Daniken doesn't mention the crucial fact that Chargaff discovered that the amounts of A roughly equal the amounts of T in DNA, and the same holds for C and G. Most importantly, he misses the crucial feature of DNA: AT and CG form pairs. And that's the crux of genetic information. He is often distracted by asides and story telling. On another page he knows that "the order of the four bases" is important and "only certain basic bases fit into the sequence ... Others cannot dock at all" without mentioning AT and CG pairs! So, strictly speaking, he didn't get the most important feature of DNA, but he is close. 

As is often done by non-biologists, he mistakes the concept 'genetic code' for the genome (the total of DNA in a cell or of a species). This is wrong. The genetic code is the way the information in DNA is translated into proteins. That is: how 64 base triplets code for 20 amino acids. And that can be done in a million ways. As a consequence of this misunderstanding he never wonders how DNA works and what it does. He is completely unaware of the fact that the genetic code cannot be derived from biochemical laws. It has an arbitrary character. The genetic code of all life on earth is unique to life on earth. It is not an universal law. And this explains why he doesn't see a problem with aliens injecting DNA in humans. This could only be meaningful if the alien DNA had the same genetic code (in the scientific sense) as life on earth. The smallest difference in the genetic code could create an obstacle. Significant deviations from our genetic code, makes 'injecting alien DNA' pointless, even pathogenic.

Not surprising, he quotes the panspermia theory of Fred Hoyle and Chandra Wickramasinghe, because according to this theory the first DNA came from space. He also fully accepts and defends Intelligent Designer Michael Behe's Darwin's Black Box. In Von Daniken's view Intelligent Design means aliens. Aliens created DNA and had sex with humans. Or something like that.

His description of Darwin is short but factual without any Darwin bashing. He includes an illustration of Darwin's finches (!) in the book. So far so good. But, the only occurrence of the concept of 'natural selection', crucial for Darwin's theory of evolution, is in a quote: "A Scientific Dissent from Darwinism [1] ..."  (Intelligent Design!). I found one occurrence of "Darwin's selection (choice)". That's all. As often happens he uses 'survival of the fittest' in stead of 'natural selection'.

Apart from uncritical acceptation of Michael Behe and the Intelligent Design movement, he manages to refer to Hans-Joachim Zillmer Die Evolutions-Lüge. If you start accusing your opponents of lies, then you stop thinking scientifically. He also uses and quotes from Reinhard Junker, Siegfried Scherer (1998) Evolution, Ein Kritisches Lehrbuch. The book has been criticized thoroughly by evolutionary biologist Gerdien de Jong on this blog [2]. Von Daniken says about the book: "excellent work"!!!  However it is not an evolution textbook as Gerdien de Jong explained. There is no evolution textbook mentioned in Evolution is Wrong. So, he knows 'evolution is wrong', but did not read any of the many professional or popular evolution textbooks. There are hundreds of them! [3]. I recommend the excellent and popular book Jerry A. Coyne (2009) "Why Evolution Is True". This is a very complete overview, but it is not a textbook in the sense that for example the structure of DNA, Mendelian and molecular genetics are explained. If only Von Daniken had read this book, he would have known the arguments and facts in favour of evolution. I think he is able to understand everything in the book provided he takes the trouble to study it carefully. Another example of his one-sided reading habits is the fact that he read Dawkins Der Gotteswahn (The God Delusion) in stead of the famous The Selfish Gene. He would have learned a lot about evolution if he had read it. It is available in German: Das egoistische Gen.

 

Conclusion

I was curious about Von Daniken's knowledge of evolution and DNA in his recent Evolution is wrong. I must conclude that his knowledge is fragmentary; there are some surprising bits of knowledge: Evo-Devo, genetic toolkit, CRISPR, genetic knockout, and some fragments of the history of science, but he misses crucial insights and facts.


Notes

  1. "We are skeptical of claims for the ability of random mutation and natural selection to account for the complexity of life" (Intelligent Design credo)
  2. Gerdien de Jong: Der geist der stets verneint. Weglaten, verkeerd weergeven, verdraaien, misleiden, 15 December 2010. We have created a website devoted to the Junker & Scherer book with a few English abstracts.
  3. I have collected all the current evolution textbooks and introductions to evolution on my webpage Introduction to the evolution literature. I could not find a German translation of Coyne's book, so Daniken has to read it in English!
  4. P. Levene discovered and described all the components of DNA, but Watson and Crick (1953) did not refer to him. This demands an explanation. I have to find out what's going on. [29 Jan 2023]

 

This is a tweetblog: a short blog to report news quickly without all the details of a full review. I have used the KOBO ebook. I discovered today that for the first time I can read my books in the browser, that is in full color! and on my computer screen! (logged in with my KOBO account). All KOBO e-readers are black and white. So, this is a huge step forwards.

I am working on an extended version which will appear on my WDW website.
