Stephen Fletcher Flogs Stephen Meyer

See here:

Here's an excerpt I liked:

In the prologue to his book Signature in the Cell, Stephen Meyer states that it is an attempt to make a comprehensive, interdisciplinary argument for the Intelligent Design view of the origin of life. But as the author himself concedes (in an appendix on page 496), the discovery of a precursor to DNA (such as RNA) would demolish the whole edifice. A “key prediction” is that “Future experiments will continue to show that RNA catalysts lack the capacities necessary to render the RNA world scenario plausible”. It is Stephen Meyer’s bad luck to have published his book in 2009, the very year that the RNA world scenario became eminently plausible. In February of that year came the discovery of the self-sustained replication of an RNA enzyme, by Lincoln and Joyce (Science, Vol 323, pp1,229–32). In March came the identification of the prebiotic translation apparatus (a dimer of self-folding RNA units) within the contemporary ribosome, by Yonath et al (Nature Proceedings, Posted March 4, 2009). Finally, in May came the discovery of the synthesis of activated pyrimidine ribonucleotides in prebiotically plausible conditions, by Powner et al (Nature, Vol 459, pp239–42). I am afraid that reality has overtaken Meyer’s book and its flawed reasoning.
