Michael Denton on Junk DNA

I was reading the latest spiel from Sal Cordova (scordova) when I noticed a reference to Michael Denton. Cordova was ranting about how Taxonomic nested hierarchies don’t support Darwinism and he began with ...

Taxonomic nested hierarchies don’t support Darwinism or common descent, actually the opposite. Michael Denton convincingly argued that nested hierarchies can be used to argue against macro evolution. If the fish are always fish, then they will never be birds, reptiles, apes, or humans.

I knew that this was a misrepresentation of Denton's views since he (Denton) supports the idea that nested hierarchies represent the true history of common descent.

Michael Denton thinks that evolution was directed and that explains why fish and mammals are so different even though they contain a common ancestor. He accepts common descent but rejects spontaneous mutation and mechanistic fixation of alleles as the explanation. I checked his latest book Nature's Destiny (1998) to confirm that I was right.

Denton supports a teleological view where God created conditions (first cause) that would lead to humans (final cause) but that the process included evolution from common ancestors. In Denton's case the "design" was inherent in the laws of physics and chemistry and the rules of mutation and gene expression.

While refreshing my memory, I came across this paragraph that I had highlighted in his book fifteen years ago.

If it is true that a vast amount of the DNA in higher organisms is in fact junk, then this would indeed pose a very serious challenge to the idea of directed evolution or any teleological model of evolution. Junk DNA and directed evolution are in the end incompatible concepts. Only if the junk DNA contained information specifying for future evolutionary events, when it would not in a strict sense be junk in any case, could the finding be reconciled with a teleological model of evolution. Indeed, if it were true that the genomes of higher organisms contained vast quantities of junk, then the whole argument of this book would collapse. Teleology would be entirely discredited. On any teleological model of evolution, most, perhaps all, the DNA in a genome of higher organisms should have some function. (pp. 289-290

I wonder what Intelligent Design Creationists think of this argument?
