Statistical arguments, used for Evolution, make use of "a whims of the Gods" approach to science. If you need anything to happen, the gods of random can make it happen to fill in the blanks. Faith is the belief in things not seen. Faith is part of evolutionary science; belief in things not seen, or else the whim of the gods approach would not be needed so you can pretend to see. That is why when challenge to run an experiment there is a pause since their gods may not show up.
In the late 1950's, as observational technology improved, it was observed that proteins fold with exact folding. This was unexpected, since the then prevailing theory in biology was based on the average folding of protein due to random thermal fluctuations in water. This theory had been around for decades and was based on statistical arguments. Exact folding was not a term used in statistics, since it implied probability of 1.0; sure thing = logical.
Although the biological sciences should have advanced its approach upward toward reason, due to this evidence, here we are 60 years later and statistical arguments for life are still being used. This continued obsolete approach has turned the sciences of the origins of life, into a type of whims of the gods religion. There is no need to reason properly since the gods will provide.
In practical terms, the absolute approach was retained because the biological industries were expanding in the 1950's, and they needed lots of skilled able bodies to man the factories. The statistical approach was more conducive to a larger labor force, since reasoning was newer and harder than a generic procedure, and therefore could place limits on the scale of the work force. Science is beholden to government and business, so money talked and science walked, instead of ran.
The reason proteins fold with each folds is because protein fold to minimize the free energy of the water; solvent, in which there are dissolved. This minimal free energy sweet spot, results in a unique exact folding arrangement that is always the same; exact folds. Lifeforms or the physical forms by which biology catalogs all types of life, is based on how water folds and then integrates all the proteins, that make up each life form to minimize the free energy of the water.
Genetics is important since it provides the raw materials for the water-protein construction process. But the water-protein construction is what creates the final life forms, which are cataloged by science, and then used as the basis for what we call evolution. Even the fossils are artifacts of the water-protein construction processes. There is currently too much emphasis on the DNA, based on the whims of the gods; jackpots assumption. Logic sees this differently, since the dominant water-protein construction, that defines all levels of form, sets both the macro and micro stages for how the DNA is used to further minimize the free energy in water.
As an analogy, all computer manufacturing companies such as Dell, Apple, Microsoft to name a few, buy similar processors from Intel, as well as similar components from common manufacturers. These parts are the genes on the DNA. Although each company buys similar parts, each company constructs these in their own style, which gives them market share at various quality and price points. These final forms help to decide what is needed to advance; feedback to Intel. Apple has Intel make avery specific set of processors which are optimized to its software needs. Water can act like a binary switch to reflect and feedforward the dynamics information flow from the organics.
