4.b) Objectives of life and theory of evolution of man
Setting aside the purely philosophical position, the final aim of Life is unknown; however, we can indeed analyze some of the instrumental objectives that logically exist or should exist in general.
Besides, the progression of humankind helps us to reach a better general understanding of the evolution of life.
Without trying to be exhaustive or include all implications of the following objectives, we are going to discuss the most relevant and essential by being present not only in the evolution of man but rather in all of the vital impulse systems. Equally, we are going to make considerations that, on the one hand, support the Conditional Evolution as a whole and, on the other hand, those that express contradictions or limitations of other theories of evolution.
It is worth disclosing there is a conceptual interrelation between the discussed objectives and between the arguments and examples used; nonetheless, to facilitate its presentation and understanding, we had considered convenient to separate them into the following points.
4.b.1. Guarantee and certainty in the evolution of living beings
In the biological evolution of man and, definitely, in all types of living beings and vital impulse systems, we will find the classic concept of the supremacy of the species or the system over the individual or particular element. In other words, the continuity of the species prevails over continuity of the individual. This vital conditioning explains the strange behavior of many living beings, justified by the necessity of guaranteeing and perpetuating the species. They can even come to killing themselves to serve as food for the offspring in its initial moments.
In genetics, the total certainty of the viability of incorporated modifications to the genome is not always necessary. Sometimes it will be sufficient with a high degree of probability; however, if genetic variation affects one of the complex and vital functions of the new being, it would be interesting to be able to attain total certainty.
A solution would be to simulate system operation under the new parameters and relations before incorporating them in the genetic information to transmit, this way avoiding any incidental variation that may cause an error.
However, the simulation method has a limitation; in very complex functions, it is not possible to simulate all possibilities, given that these can be almost infinite. It is essential to have other methods that allow maximum assurance of the viability of the new being; after all the accumulated work that represents the existence of an advanced living creature, all guarantees seem small.
An example would be the biological evolution of man.
The guarantee or certainty objective is a fundamental novelty of the Conditional Evolution because it represents an advantage of the sexual differentiation in reproduction, giving a compelling reason to its existence.
In the biological evolution of man and any living being, having two sources of genetic information when it comes to developing the offsprings poses us in the section improvement of efficiency the problem of deciding which source to use in each case.
The need for guarantee offers a coherent explanation. The viability of the new being with genetic modifications will ensue if there is a backup copy of the genome in case of failure of the innovative changes.
Therefore, a chief function of sexual differentiation could be one of the sexes providing an intact copy of its genetic packet. It is interesting in many species the female ova forms in the relatively initial moments of the individuals' development. On the contrary, it does not occur in males.
Once again, the most well-known clear example is the evolution of man.
In similar processes, even much modest than those of man, like the development of a sophisticated computer program, there are always backup copies in case the changes do not manage to obtain the anticipated result. Sexual differentiation in the case of superior animals could be a little bit similar to those computer programs developed by multiple programmers.
It is possible there is a full, or an almost entire, backup copy of the genome mentioned in the previous paragraph. Nevertheless, it is not strictly necessary for the Conditional Evolution proposals because, initially, nothing prevents a genetic modification to be incorporated maintaining, at the same time, the previous code. However, in highly related functions probably it does not exist much flexibility in the development of the new living being.
Undoubtedly, the technical and scientific progress of biology and genetics will have the last words on guarantee and certainty subject concerning the evolution of living beings; although, there will be two methods or more, keeping in mind the enormous casuistry present.
