Ironically, the rarity of genes and proteins in sequence space means that even thirty million years is not nearly enough time for the neo-Darwinian mechanism to generate a new gene or protein, much less a new animal form.

Yesterday, I introduced the subject of exon shuffling and gave a few reasons why such a mechanism cannot explain the origins of the earliest, most ancient proteins.
More on Objections to Darwin’s Doubt from University of Texas Biologist Martin Poenie
Biologists, unlike chemists or physicists, tend to think they are doing science when they name things.
Exon Shuffling, and the Origins of Protein Folds
A frequently made claim in the scientific literature is that protein domains can be readily recombined to form novel folds.
More Clues that Intergenic DNA Is Functional
You’re an enzyme of RNA polymerase floating in the nucleus of a cell. Your job is to transcribe a gene, but you are blind and it’s dark.
