er and a trunk will never grow in a wolf either, even if there would be a sudden need in it, at least, for sure, not during the lifespan of one generation. But if me myself, for example, need right now to "reconstruct" a hand to extend it and to tear off a fruit from a tree, should I then wait for several generations to pass for my hand to grow and extend? Can't one get transmuted without resorting to metabolism? It is possible if "conscious" self-organization is added. All living beings, including humans, have genetic system of contingency self-organization and in this sense the human being is the same animal as any other animal. But "conscious" and purposeful type of self-organization is only inherent in human beings. Systems with preset (Target-oriented) properties will always be forming only in the event that organization or reorganization of systems is purposeful. Only the control block "Knows" about the goal of the system and only it can make a decision, including on the system reorganization. However, not each control block is suitable for target-oriented reorganization. In order to decide that "that system" needs to be attached to itself it is necessary to "see" this system, know its property and define, even prior to beginning interaction, whether these properties suit for the achievement of its own purpose. And for this purpose it is necessary to be able to "see" and assess the situation around the given system. All self-training systems are able of making such an analysis. Therefore, many higher animals can reorganize their body by enhancing its possibilities with additional executive elements. They use tools of work (stones, sticks, etc.) for hunting food. But these animals, perhaps, act at the level of instincts, i.e. at the level of genetic self-organization, because even insects can use work tools. True "conscious" self-organization at the given stage of evolution is only present in human being because only he/she has analyzers-abstractors of respective degree of complexity. Only the human being could develop instruments of labor up to the level of modern technologies because it has second signaling system which helped to accumulate the experience of the previous generations by fixing it in the abstract form, in the form of the script. And only the human being using this experience has realized that there exists metabolism in a living organism and that it is possible to influence an organism so that to reorganize, if the need arises (to cure sick organism). Structural regeneration is intended for conservation of the systems 'structure. However, metabolism is not a full warranty from the destruction of systems either. Plants cannot foresee the forthcoming destruction because they do not possess the notion of space and they do not see the situation around them, because they have simple control block. Fire will creep up and burn a plant, the animal will approach and eat it, while the plant will quietly wai...
