Шрифт:

At reproduction the repetition in consecutive generations of identical forms of exchange is manifested. Successors receive the program of exchange in the form of molecules DNA, on the basis of which they produce own signs and properties.

This program is found in genes of every cell of any organism, the totality of which constitutes the genotype of the organism.

Genotype is a system of interacting genes, manifestation of each of which depends on other genes and from the general genetic environment.

The genotype became complicated in the course of evolution. In particular, if at the elementary organisms – viruses – it contained tens of genes, then at the highest mammals the quantity of genes in a genotype has increased up to tens of thousands.

Owing to interaction of a genotype and the external environment the genotype is shown in it in the form of a number of signs (phenotype): the number of signs has compliance with number of genes.

The most harmonious interaction of an organism through a phenotype with the environment is noted by natural selection in competitive struggle of organisms with fixing in chromosomes of the genes corresponding to these signs, with the subsequent inheritance of the fixed genes. Descendants thereby receive genes which determine emergence of these or those signs. Material for natural selection are, as a rule, random changes (mutations) of the genotype as a whole or any part of it. Mutations can be harmful or beneficial for the organism depending on the conditions of its existence [1. Ch. 3].

In this short description there are no answers, at least, on two major questions: from where emerged the first simplest organisms with predetermined programs on the protein carrier. and why the genotype of organisms began to become complicated.

Indeed, the spontaneous formation of the simplest programs on the protein carrier has the probability close to zero, even in the calculation for billions of years. This fact implies the impossibility of spontaneous appearance of the living beings, who, however, has appeared on Earth.

Complication of the elementary organisms the genetics explain by the arbitrary character of this phenomenon, that in itself isn't scientific, inasmuch the complex process of natural selection is given at the mercy of arbitrariness, whereas any live organism acts in strict accordance with the program which is available in the genome. This program assumes use of any failures (mistakes) during realization, in particular, the programs of replication, by means of remembering and application, at their positive influence on the reproduction process, fixing these failures in the available program, i.e. adding an extra combination of links to the former links, recorded in the program.

Thereby this procedure, on the one hand, increases number of combinations of links in a genome, complicating it, and on the other hand, this process of use of new links, positive for replication, in effect, means gradual formation of some kind of reflexes on the remembered irritation that, naturally, is reflected on a phenotype.

All these consequences of mutations have no relation to arbitrariness and they find an explanation, first, in the inescapable deep activity of the living organisms distinguishing them from lifeless objects, that is called by consciousness, and secondly, in possession by any living organism of the complex program, allowing a organism to develop, i.e. to multiply, become more complicated, retain own structure from disintegration by effective exchange of substance and energy with the environment.

By itself, the process of complication of living organisms in the course of their interaction with the environment is the derivative from the process of their adaptation to the environment, which along with the dominant process of complication of the organisms can be manifested and in stability of organisms to the change long time, if they find full compliance with the environment, and the failures in their programs are of a balanced character, without influencing, for example, on the reproduction process in any way. In this case the program on the protein carrier remains almost invariable on the action, how and a phenotype, which is manifested in appearance and structure of an organism (some viruses and bacteria).

Thus, evolution represents gradual accumulation of the various, more or less difficult living beings appearing and disappearing during natural selection during billions of years. These beings are characterized by the full unity with the environment, i.e. they aren't capable to separate themselves from the environment independently, because the action program which is written down in genes of each living being determines it as a component of the living environment, the sole support which is a reflex activity, but not as the certain subject of conscious-target impact on the environment.

It is possible to understand this representation by analogy with operation of the computer according to various programs, introduction of which changes properties of the computer, but which the computer isn't capable to generate independently.

If, nevertheless, to allow the emergence of such independence, then becomes inexplicable absence of similar transformation, for example, at a chimpanzee during millions of years, whose genome only for 1% differs from the human genome.

All this clearly indicates the lack of smooth evolutionary transition of the primate, merged with the nature, into the creative person, which is separated from nature to a large extent
