I’m just reporting the what needs to change, the lentis retractor muscle (in some fish) to the ciliary muscles (in humans). This also involves changes in neurons and coordination. Obviously you and Dr. Harshman think this is a sufficiently easy transition, but I (and I expect some of the readers of the books project) to consider it absurd.
I KNOW from experience that when I start describing things like this in detail, people are inspired with wonder at the Creator and how insufficiently Darwinisim (and/or even neutral theory) are as explanations. I point out, fossils like the fishapod don’t explain the sort of fine transitions that are actually needed to convert a fish to a human. I point out the absurdity of suggesting that this fossil
is good reason to believe the lentis retractor muscle in some fish can evolve into a ciliary muscle in humans.
Phylognetic reconstructions and nested hierarchies are not adequate to explain the issue of mechanistic feasibility of the numerous examples listed in this thread.
Many proteins like Zinc Fingers have specific binding targets on the genome at fine-tuned levels of binding affinity.
I demonstrated elsewhere the absurdity of nested hierarchical reasoning as some sort of mechanistic explanation for the evolution of Zinc Finger arrays:
The spelling of individual zinc fingers must be coordinated to bind with the right specificity and affinity to precise segments on the genome, otherwise the protein fails to funciton, and worse binds to the wrong places!
Appealing to hierarchical diagrams as some sort of explanation for how the zinc finger array matches the DNA is an absurd non sequitur.
Pointing out the non-sequitur of nested-hierarchy-type “explanations” in the above example is extensible to supposed zinc finger protein evolution between organisms, and really to nested-hierarchy explanations in general. The nested-hierarchies EXIST, but it is a non-sequitur to argue they are descriptions of the mechanical feasibility of evolving one thing to another – they are not because it takes more to make a protein functional in a functional context than just randomly evolving it. The KRAB Zinc Finger family proteins are an example.
