4. GENETICS AND EVOLUTION
4.a) Evolutionary genetics
This title IV presents new ideas about the origin of life concerning genetics and species’ evolution.
It has four main sections. Firstly, there is a brief description of genetics and evolution.
The second section stages life's objectives with the fundamental logical argument of why and how living beings' evolution develops.
Scientific progress and society
These biological systems result from more than a billion years of evolutionary discoveries, rejections, trials, successes, and perfection, which, if they have worked well, many in each step incorporates.

In most superior evolutionary processes, inevitably, there would be genetic changes produced simultaneously by the environment's influence, random mechanisms, and trial and error methods. Some changes will already have verification, sexual differentiation, and natural and sexual selection will be present.
The next two sections refer to creating primary and accurate terminology concerning genetics and the theory of evolution and 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, 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 relevant to the theory of evolution; that is, its functional character and not the molecular play, which would be more typical of chemistry, molecular biology, or genetic engineering.
The virtue of this approach is allowing any person to understand the reasoning.
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.
Furthermore, the research has found numerous sequences devoid of known function –they do not run the protein production– in all of the species studied. It indicates that they have been throughout evolution and strongly suggests that they have some biological function.

Consequently, one should not seek a perfect understanding of the explanations; instead, one should appreciate the reasoning behind the new proposals, thinking that some may be incorrect but could be in the right direction.
Remember that the knowledge of the genetic mechanisms is insufficient regarding its actual magnitude in evolution theory. **
