What are the evidences of evolution

There are a lot of versions about the origin of the world. Perhaps, one of the most reliable was put forward by the scientist 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 good evolution of animals, as well as someplants, is fixed in fossil remains, serving as one of the confirmations of how everything developed. In addition, this "paleontological chronicle" allows you to restore individual details of phylogeny. These residues are not only the teeth, bones or other hard parts of plants or animals that have been preserved, it is also any traces or imprints that left existing organisms. It must be said that at the present time 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 evidence of the evolution of the livingnature 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 in animals and bacteria and plants are 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 discoveredevidences of evolution, embryological nature. As a result of a deep study in multicellular animals in the embryonic state, there are significant similarities. 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 is in an embryonic state, however, its presence confirms the theory of evolution.

It should also be noted atavism. It is understood as the appearance of a certain trait that is characteristic of ancestors, but normally 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 evidenceevolution. 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 evolutiongives 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 geographical conditions clearly reflects the process of historical development of all living things.
