Another Icon Of Darwinism Is Falling

Having assumed that God would only create with absolute perfection and would never allow any changes to His design, critics of divine creation assert that all “useless” organs and “unneeded” features are evidence against the belief that God created life. Two of the most commonly cited examples of these alleged imperfections in God’s creation are the human appendix and “Junk” DNA.

The appendix, a little worm shaped organ that sits at a major bend in the large intestine, seemed to be doing nothing except producing trouble by occasionally getting inflamed and causing appendicitis. However, new research published in the Journal of Theoretical Biology describes the discovery of a vital function that the appendix performs. These researchers found that the appendix provides a backup system, which has been important to the long-term survival of the human race. It seems that the appendix acts as a reservoir and shelter for the digestive bacteria that populate the human gut. These are the bacteria, such as E. Coli, that help break down food and assist in its transformation into polysaccharide molecules that can be absorbed by the body’s cells.

A reservoir of these “good bacteria” is needed because certain diseases, such as cholera, and many types of food poisoning wipe out these bacteria. It is very difficult for these bacteria to repopulate the gut after such an infection without a healthy colony to act as a starter. This is where the appendix comes in. It preserves a supply of these bacteria, which, subsequent to the eradication of friendly bacteria in the gut, are released back into the intestine, allowing the digestive system to come back online quickly to resume digesting food and to enable the victim to recover. Without an appendix, some common maladies would be fatal more often.

Oh yes, regarding “Junk DNA,” those sections of DNA which do not code for protein production, on August 25th this Blog published an article on new research done by the Encode Project showing that at least 50% of the so-called “Junk DNA” is not “Junk” at all, but indeed has numerous vital functions. As research continues on “Junk” DNA, more functions are being discovered for it. It seems that ultimately all of this “junk” will be found to have a vital purpose.

New research shows that these non-protein-coding DNAs are playing the pivotal role of “conductor” in regulating the cell’s activities. They produce huge numbers of micro-RNAs, which regulate gene expression and thereby “conduct” the activities of the coding sections of the DNA molecules. This is no small thing; these micro-RNAs are like little mid-level managers, accountants, and quality control agents in a factory. They are responsible for making sure that the right proteins get to the right place at the right time and much more.

This new, vast level of cellular complexity has been labeled the “Conductome.”

Why This Is Important

The existence of currently useless organs (if such actually exist) does not prove that God did not design them. It arguably could show that God was slow to remove them or, the truth be told, what it actually shows is that we have failed to understand their purposes. However, the existence of vestigial organs is necessary to the Darwinian claim of evolution by purely natural processes. If an organ is no longer needed, random mutations should begin to destroy it through the accumulation of small changes which do not effect the overall fitness of the organism

These two icons of Darwinism, the appendix and junk DNA, have been so widely touted in the literature that it will probably take decades before they are expunged. However, the Darwinists will soon advance new examples in their effort to discredit God’s role in creation. After all, in their view, Darwinism is unfalsifiable; so the evidence against it does not shake them.
