What are the evidences of evolution

There are a lot of versions about the origin of the world. Perhaps, one of the most reliable scientists put forward Darwin in his famous works. He relied on the existing evidence of evolution, which after it was repeatedly investigated and confirmed. The facts that speak about the consistent development of the organic world are sufficiently convincing and diverse. They prove that all living things on Earth arise from already existing species as a result of hereditary changes.

Very well the evolution of animals, as well as of some plants, is recorded in fossil remains, serving as one of the confirmations of how things developed. In addition, this "paleontological chronicle" allows you to restore individual details of phylogeny. These residues are not only the teeth, bones or other solid parts of plants or animals that have been preserved, but also any traces or imprints that left existing organisms. It must be said that at present only a small part of what forms of life existed on the planet have been discovered before. Continue to explore and observe this paleontologists, scientists involved in the collection and interpretation of data on ancient organisms.

It must be said that the proofs of the evolution of living nature are divided into several groups. So, there are confirmations that are based on the unity of origin of the organic world. This includes the fact that almost all organisms have a similar elementary chemical composition. Very important in life phenomena and in animals, and in bacteria and plants, proteins and nucleic acids, always built from similar components. Almost all organisms have a cell structure . ATP is used as a molecule that accumulates energy.

Domestic and foreign scientists have discovered evidence of evolution, embryological nature. As a result of in-depth study, there are significant similarities in multicellular animals in the embryonic state. Especially distinctly observed are the same signs in embryos belonging to the same class or type. Thus, in land vertebrates, the bookmark of the gill arches is marked in the same way as in fish, although in adult individuals they do not have functional significance. This suggests that all living organisms have a unity of origin. The manifestations of evolution include the rudiments of man, that is, undeveloped parts or organs of the body. The most common of these include the coccyx, which is a triangular bone formed from several fused vertebrae. Once it formed a tail, however, with the transition to the uprightness the need for it fell away. As a result, this organ in a person is in its infancy, however, its presence confirms the theory of evolution.

It should also be noted atavism. It is understood as the appearance of a certain trait, which is characteristic of ancestors, but in the norm it should not be present in modern man. For example, it can be a strong hairiness, the presence of more than one pair of mammary glands, etc.

Mark and morphological evidence of evolution. Among them, forms that combine the signs of large systematic units are of particular value. In addition, scientists drew attention to the fact that in some vertebrates the structure of the forelimbs is fundamentally similar, in spite of the fact that they perform different functions.

A rich scientific material for the study of evolution gives comparison of the animal world of various natural areas. The distribution of various types and types of the planet and their further grouping according to geographic conditions clearly reflects the process of historical development of all living things.
