That QBD seemed to have potential for a brief moment but it got just too weird for me. Not enough science and too much conjecture. But back to DNA.
The sugar-phosphate groups tied together by those cytosine-guanine, thymine-adenine base pairings, in spite of the apparent complexity of the whole, make for a very simplistic structure. C is always paired with G; A is always paired with T. They make for a total of four possible groupings: C-G; G-C; A-T; and T-A. It becomes the sequential ordering of the base pairs in a gene, allowing for repetition, that provides the overall complexity of the molecule and individual diversity and uniqueness to the whole organism.
My thinking has returned to the patterns of nature being repeated at different levels. For example, the farther that two quarks are forced apart the stronger the energy is between them. When they come close together something called a gluon mediates their relationship such that they don't collide but instead marry. Similarly, the bringing together of molecules to form a functional component of a greater scheme, just like the quark joins two other quarks to make a proton, is also mediated, but by hydrogen which permeates throughout the organism and which bonds the bases together.
There is a tendency for organisations in nature to rotate and DNA is no exception. This probably catalyses the assembly during reconstruction after donating one half of a portion of its structure for template production for the purpose of protein synthesis.
On the one hand, the simplicity of the structure definitely suggests an evolutionary influence which is randomly guided. That is, probability is proportional to simplicity. On the other hand, the complex sequence of events that ultimately produce the characteristics or functions that are the product of the molecule's inherent coding suggests an intelligent blueprint. Because of the huge evolutionary time frame one might still lean toward randomness, and insomuch as necessity is the mother of invention and the need to evolve an adaptive trait is influenced externally, so we are still left with a survival of the fittest scenario, and this also implies limited self-determination.
It is probable that the accelleration of the process of evolution is proportional to the increase in cognizant self-awareness which in turn is proportional to the complexity of the whole organism. In other words, we had a guiding hand in our own evolution. Determination becomes the neutrino in the particle analogy.
