The establishment of beneficial changes in living organisms due to environmental influences and their transmission to new generations with sexual cells… The English scholar Charles Darwin proved that the main factors in the evolution of living organisms are ‘mutation’, ‘selection’ and ‘heredity’. Environmental effects cause changes in living organisms. While these changes are beneficial, there are also harmful ones. harmful changes destroy living organisms.
Changes that are beneficial improve living organisms. This means that those who can adapt to environmental conditions live and continue their species, while those who cannot adapt to environmental conditions die. This is a selection, in Darwin’s words, ‘natural selection (Fr. selection naturelle)’. Changes useful in this sorting are located in the molecules of nuclear nucleic acids in living organisms and are passed on to new generations by sexual cells. Heredity, or heredity, expresses variational traits that are transmitted from generation to generation by these material conductors.
By discovering the material conductors of heredity, contemporary life science (biology) has fundamentally refuted the metaphysical arguments linking this phenomenon to supernatural causes. Without the ability of heredity in living organisms, changes caused by environmental influences would remain both individual and powerless, and would not be able to provide species development by not passing on to new formations of the organism through evolutionary strengthening.
The development of organic nature (living nature) takes place through the ‘contradictory struggles’ of opposing laws of ‘change’ and ‘heredity’. The law of ‘variation’ provides dissimilarity, the law of ‘heredity’ provides similarity. That’s why children are both similar and unlike their parents (they are different N.), there is no child who is exactly like the parents and there cannot be. In a famous saying, “There is no stereotype pressure in nature”. (found in asexual reproduction N.) Natural selection takes place by the contradictory operation of these two opposing laws and ensures the development of organic nature. Change creates useful new traits, while heredity accumulates them and produces new species in living things. (heredity enables living things to resemble themselves for a long time and remain in their own kind, while change enables them to gradually change and speciate N.) Natural selection continuously improves the structure and functions of the organism, and reinforces its adaptation to the external environment by evolving it.
Selection in domestic conditions is called artificial selection, selection in natural conditions is called natural selection.
