Death in Biology

The greatest interest in Freud's study led the length of life and death of organisms in the works of A. Veysmana, proposing the division of "living substance" on the death and the immortal half. Death Veysman considered part of the body itself, SOMU prone to natural death, as the immortal part considered germ cells, as they can, under appropriate conditions to develop into a new organism, to create a new SOMU. Freud finds this analogy with his theory of "attraction" of two families - those that are life unto death, and those who are constantly striving to upgrade life. However, he frankly acknowledged that "the visibility of the coincidence of rapidly disappears when we read with a resolution of the problem Veysmanom death. Veysman fact allows a distinction of catfish immortal germplasm only in Metazoa (multicellular). The death of the higher living beings have a natural death from internal causes, but it is based not on the original properties of living substance, can not be understood as an absolute necessity justified the essence of life. Death is more a sign of viability, a manifestation of adaptation to external conditions of life, as in the division of cells in the body SOMU and germplasm unlimited life expectancy of individuals would be totally impractical luxury. With the onset of the differentiation of the multicellular death is a possible and desirable. From this stage, catfish higher organisms die due to internal reasons, to a certain time, the simplest is still immortal. In contrast, reproduction was not introduced to the death, but a primitive property of living matter, such as growth, from which it occurred, and the life left on Earth since its beginning uninterrupted. " As for Freud, all these issues are important from the viewpoint of applicability to the theory he said with regret that the recognition of natural death for higher organisms little help resolve his issue. Indeed, "if death is only later acquire the living creatures, the craving for death, which date back to the beginning of life on Earth, once again been neglected. may die from internal causes of the shortcomings of metabolism, for an issue that interests us is does not matter. " In contrast to Freud's cause of death are interested in us regardless of the theories related to the disciplines of biology. But do not make mistakes whether we are trying to solve the notion of "death" is provided? In times of antiquity and Middle Ages in mind the scientist (and even more so the average person) was not so discreetly, as in our time. Obviously, the amount of knowledge accumulated by mankind, is so great, that does not allow us to have a panoramic view of the existence, at once to cover all the possible models, confirmed by theoretical and practical experience of civilization.
