There is no mutation. Even the example you cite is gene expression. The genetic information is there and it is complex, it is not random.


Care to address this issue. My point is that it takes effort and design to make things happen. They do NOT happen at random. Mutations are DAMAGING TO THE SYSTEM. There is so much redundancy to CORRECT mutation but of course, that is random also I suppose.

If anything there is evidence for devolution, defined as losing genetic information.

I, and most scientists, emphatically disagree with you. I will quote wiki on the potential for beneficial mutations. As I'm getting quite weary of creationist pseudo science: Although mutations that cause change in protein sequences can be harmful to an organism; on occasions, the effect may be positive in a given environment. In this case, the mutation may enable the mutant organism to withstand particular environmental stresses better than wild-type organisms, or reproduce more quickly. In these cases a mutation will tend to become more common in a population through natural selection. For example, a specific 32 base pair deletion in human CCR5 (CCR5-Δ32) confers HIV resistance to homozygotes and delays AIDS onset in heterozygotes.[70] One possible explanation of the etiology of the relatively high frequency of CCR5-Δ32 in the European population is that it conferred resistance to the bubonic plague in mid-14th century Europe. People with this mutation were more likely to survive infection; thus its frequency in the population increased.[71] This theory could explain why this mutation is not found in southern Africa, which remained untouched by bubonic plague. A newer theory suggests that the selective pressure on the CCR5 Delta 32 mutation was caused by smallpox instead of the bubonic plague.[72] Another example is Sickle-cell disease, a blood disorder in which the body produces an abnormal type of the oxygen-carrying substance hemoglobin in the red blood cells. One-third of all indigenous inhabitants of Sub-Saharan Africa carry the gene,[73] because, in areas where malaria is common, there is a survival value in carrying only a single sickle-cell gene (sickle-cell trait).[74] Those with only one of the two alleles of the sickle-cell disease are more resistant to malaria, since the infestation of the malaria plasmodium is halted by the sickling of the cells that it infests.
