The very fact of evolution, that is, the species changes in the carriers of life in comparison with the "original plan," can not be denied even by religion. But intelligently to explain the driving forces of evolution can not still be science, although on this account more than two dozen theories have already been created.
Without claiming an all-encompassing description of the phenomenon of evolution, I propose by no means a fantastic, perhaps new, hypothesis that satisfactorily explains such important aspects of evolution as suddenness and spasmodicity (ie, the absence of intermediate forms of life between species) and the simultaneous appearance (or disappearance) of species throughout the planet .
On this hypothesis I was prompted by the popular scientific book of VI. Govallo "Why do not we look alike" (M. Znanie, 1991). The essence of the answer to the question posed in the title is the availability (and not only in humans) of tissue incompatibility proteins. They are, as is widely known, a problem in medicine for organ transplantation. The same problem they create any penetration into the inner life of any organism, protecting the biological individuality of their owners. In this regard, the smallest of its inhabitants are viruses, the largest enemy of any organism on the planet. Tigers-cannibals, sharks-killers can eat several people, an inconspicuous virus that is everywhere (in the air, in water, in food) - millions and billions, for example, the virus that causes AIDS, practically everyone!
How does the virus work, in an attempt to overcome our immunity?
The main task of the virus is to deceive the enemy's information system, that is, the DNA of the body cell, to which it attacked, otherwise it will not be spiced up. To do this, the virus, breaking the shell of the cell, and penetrating into its nucleus, leaves there "its person" in the form of a site of its DNA instead of the site of the victim's DNA, and takes for itself this "site of master DNA" as the "language". This is confusing the immune system (for some time or at all), and the virus continues its black business.
Not necessarily a disease caused by the aggression of viruses, leads to death - it can "simply" change the body, making it even invalid. But there are inherited diseases - and this is even though small, but the difference is within the species.
Why not imagine that such a virus can emerge that will lead to such a hereditary disease, and in all (or most) in this form, that the difference of the sick organism from the healthy will become cardinal - a completely new kind is formed? And because the virus replaces a whole piece of DNA, then the transition to the new from the old will happen in a leap, without transitional forms. Therefore, for example, the trunk of an elephant has grown not in millimeters per year, but immediately. And because viruses spread all over the planet everywhere and quickly, the formation of a new species occurs everywhere and simultaneously.
The emergence on the planet of completely new viruses, to protection from which immunity is not ready, is most likely connected with planetary catastrophes, when the habitat changes dramatically for a long time and over a large territory (yes, and under new conditions of life immunity fights, first of all, With them, and it's not enough to fight against viruses - that's why, for example, when we cool, we get sick). But it is possible and the assistance in this simple mutations.
So, the birth of "unknown animals" is not a fairy tale.
It must be admitted that the author is not an expert in the affected area, therefore this material is a discussion one.
