4.b) Objectives of life and human evolution
Regardless of a purely philosophical position, Life's final aim is unknown; however, we can indeed analyze some of the instrumental objectives that logically exist or should exist in general.
Without trying to be exhaustive, the discussion will be about the essential objectives, which are being present in man's evolution and all vital impulse systems. Equally, the considerations relate to the Conditional Evolution of Life –CEL– support and the contradictions or limitations of other theories.
It is worth disclosing a conceptual interrelation between the discussed objectives and the arguments and examples used; nonetheless, the presentation separates them into the following.
Guarantee and certainty
Efficacy and optimization
Internal coherence or compatibility
4.b.1. Guarantee and certainty in the evolution of living beings
This vital conditioning explains many living beings' strange behavior, 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 incorporating 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 new being's complex and vital functions, it would be worthy 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, avoiding any variation that may cause an error.
However, the simulation method has a limitation; it is impossible to simulate all possibilities in very complex functions. It is crucial to have other ways allowing maximum assurance of the new being's viability. All guarantees seem small after all the accumulated work for the next advanced living creature.
An example would be the biological human evolution.
The guarantee is one of the fundamental novelties of the CEL because it represents an advantage of the sexual differentiation in reproduction, giving a compelling reason to its existence.
Section improvement of efficiency poses the problem of deciding which source to use to develop the offspring with two genetic information sources.
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; 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 human evolution.
Like developing a sophisticated computer program, there are always backup copies if the changes do not manage to obtain the anticipated result in similar processes much modest than those of man. Sexual differentiation in superior animals could be a little bit similar to those computer programs developed by multiple programmers and needing copies and compatibility.
There may be a full or almost complete backup copy of the genome mentioned in the previous paragraph. Nevertheless, it is not strictly necessary for the CEL proposals because nothing prevents a genetic modification from incorporating maintaining, at the same time, the previous code. However, it probably does not exist much flexibility in developing the new living being in broadly related functions.
Undoubtedly, biology and genetics’ technical and scientific progress will have the last word on guarantee and certainty. Although, there could be two methods or more, keeping in mind the enormous casuistry present.
