4. GENETICS AND EVOLUTION

4.a) Evolutionary genetics

This title IV presents new ideas about the origin of life concerning evolutionary genetics and its consequences on the evolution of the species.

It has four main sections. Firstly, there is a brief description of genetics and evolution.

The second section stages the objectives of life with the fundamental logical argument of why and how the evolution of living beings develops.

These biological systems are the result of more than a billion years of evolutionary discoveries, rejections, trials, successes, and perfection, in which many of which has worked well in each step incorporates.

In the majority of the superior evolutionary processes, inevitably, there would be genetic changes produced simultaneously by the influence of the environment, random mechanisms, and methods of trial and error. Some changes will already have verification, sexual differentiation and natural and sexual selection will be present.

The next two sections refer to the creation of primary and accurate terminology concerning genetics and the theory of evolution, and to cite some examples that may help to familiarize and identify the terms employed.

It is worth pointing out that the purpose is not to explain modern biology or genetic engineering terms like types of molecules, proteins, their three-dimensional forms, specific biological functions, or molecular processes of chemical nature.

On the contrary, the analysis focuses on what nature does, on the general procedures and methods that it probably uses, the processes, and the particular conceptual mechanisms.

For example, there are biochemical mechanisms that give place to random processes, which are relevant to the theory of evolution; that is, its functional character and not the molecular play, which would be more typical of a course in chemistry, molecular biology or genetic engineering.

The virtue of this approach is allowing any person to understand the reasoning.

Furthermore, the research has found numerous sequences devoid of known function –they do not run the production of protein– in all of the species studied. It indicates that they have been throughout evolution and strongly suggests that they have some biological function.

However, sometimes the logic can become complicated due to the amount of precision and nuances necessary in the explanations.

Perhaps the main drawback of this exposition is to include intuitive ideas contrary to what academia repeats and repeats with suspicious insistence.

Consequently, one should not seek a perfect understanding of the explanations; instead, one should attempt to appreciate the reasoning behind the new proposals, thinking that some of them may be incorrect, but could be in the right direction.

Keep in mind that, now, the knowledge of the genetic mechanisms is insufficient regarding its actual magnitude in the theory of evolution.*
