Genetics

The DNA molecule is one of the greatest scientific discoveries of all time. First described by James Watson and Francis Crick in 19531, DNA is the famous storehouse of genetics that establishes each organism's physical characteristics. It wasn't until mid-2001, that the "Human Genome Project" and Celera Genomics jointly presented the true nature and complexity of the digital code inherent in DNA. We now understand that the DNA molecule is comprised of chemical bases arranged in approximately 3 billion precise sequences. Even the DNA molecule for the single-celled bacterium, E. coli, contains enough information to fill an entire set of Encyclopedia Britannica.

In recent years, scientists have applied information theory to biology, and in particular to the genetic code. Information theory is the science of message transmission developed by Claude Shannon and other engineers at Bell Telephone Laboratories in the late 1940s. It provides a mathematical means of measuring information. Information theory applies to any symbol system, regardless of the elements of that system. The so-called Shannon information laws apply equally well to human language, Morse code, and the genetic code.

The conclusion drawn from the application of information theory to biology is there exists a structural identity between the DNA code and a written language. H.P. Yockey notes in the Journal of Theoretical Biology:

It is important to understand that we are not reasoning by analogy. The sequence hypothesis [that the exact order of symbols records the information] applies directly to the protein and the genetic text as well as to written language and therefore the treatment is mathematically identical.

This development is highly significant for the modern origin of life discussion. Molecular biology has now uncovered an analogy between DNA and written human languages. It is more than an analogy, in fact: in terms of structure, the two are "mathematically identical." In the case of written messages, we have uniform experience that they have an intelligent cause. What is uniform experience? It simply means that people everywhere observe a certain type of event always in association with a certain type of cause.

DNA (deoxyribonucleic acid) is a double-stranded molecule that is twisted into a helix like a spiral staircase. Each strand is comprised of a sugar-phosphate backbone and numerous base chemicals attached in pairs. The four bases that make up the stairs in the spiraling staircase are adenine (A), thymine (T), cytosine (C) and guanine (G). These stairs act as the "letters" ...
