Can genetic mutations produce positive changes in living creatures?

[Can genetic mutations produce positive changes in living creatures? By Dr. David A. Demick, M.D.] "It is important to note that antibiotic resistance selects for traits that are already present in the population. Since there is no new information generated, it cannot be claimed that evolution is occurring.

Richard Dawkins used the idea of a “blind watchmaker” to describe how genetics can create new features in organisms through evolutionary processes. Actual observations show that natural selection acts more like a “blind gunman” as mutations occur.

Mutations occur when the genetic code of DNA changes and come in many different forms. Only the mutations in the germ cells (eggs and sperm) can be considered in inherited diseases. In a large protein, a mutation at many positions in a gene may cause a defective protein to be formed. In one cholesterol disorder, 350 disease-producing mutations have been documented to cause various problems with cell membrane receptors.

Cystic fibrosis (CF) is caused by a group of mutations in an ion pump in the cell membrane. The protein consists of 1,480 amino acids and the deletion of three bases at codon 508 causes most cases of CF. Nearly 200 other mutations have been shown to cause CF as well. Cancer is another disease that demonstrates the danger that mutations can cause to organisms. Many types of germ-line and somatic (body) cell mutations cause the cells to grow without the normal regulations on size and cell division.

If evolution has led from microbes to man, there should be some evidence that mutations can cause such an increase in information. Sickle-cell anemia is often used as an example to support Darwinian evolution, but the mutation clearly causes a loss of normal function with no new ability or information. Cancer cells are fitter than other cells around them but can hardly be considered as proof of evolution. The fact remains that observational science shows that mutations cause negative effects without a single example of a mutation that improves the function of a protein in support of evolution.

If we start from the Bible, the effects of mutations and the continued decay of the human genome is a clear example of the Curse that resulted from Adam’s sin. The human genome will become increasingly corrupted as time passes. Christ’s return and the fact that He conquered death offers the world hope for the future."
