Theoretically, it may seem difficult to propose that immense variety may occur within a group of organisms yet this variety is constrained within certain genetically induced limits. It may seem contradictory even. But in the intervening ten years, my confidence in the proposal has only strengthened, and my confidence in any evolutionary mechanism to accomplish any significant adaptational change has waned considerably. Our major objection to the role of mutations in evolutionary change is the clear lack of data to indicate that mutations really accomplish anything new. While some weird-looking fruit flies have been created in the laboratory, they are still fruit flies.
Bacteria are still bacteria.
We quoted from Pierre-Paul Grasse', the great French evolutionist. A mechanism for the creation of new genetic material is also sadly inadequate. Sometimes, an extra copy of a gene arises due to a DNA duplication error. Evolutionists suggest that this extra gene can accumulate mutations and eventually code for a new gene with a different function. In reality, however, this fails to explain how an old gene takes on a new function and new regulation pathways by the introduction of genetic mistakes into the gene and the regulatory apparatus.
