On the origin of the world a lot of versions.Perhaps one of the most reliable advanced Darwin in his famous works.He relied on the existing evidence for evolution, that after many times investigated and confirmed.The facts speak of the consistent development of the organic world, convincing enough and diverse.They argue that all life on Earth arise from pre-existing species through genetic changes.
very well the evolution of animals and some plants, recorded in fossils, evidence of one of the employees of all developed.In addition, this "fossil record" allows you to restore individual items phylogeny.These balances - is not only the teeth, bones or other hard parts of plants or animals that have been preserved, it still any traces or fingerprints that left preexisting organisms.I must say that at present, open only a small part of what forms of life existed on the planet before.Continue to explore and observe these paleontologists, scientists involved in the collection and interpretation of data about ancient organisms.
must say that the evidence of the evolution of living nature are divided into several groups.Thus, there is evidence that is based on the unity of the origin of the organic world.These include the fact that virtually all organisms have a similar elemental chemical composition.Very important phenomena in life in animals and bacteria, and plant proteins, and nucleic acids are always constructed from similar components.Cell structure have almost all organisms.As molecules that accumulate energy using ATP.
Domestic and foreign scientists have found evidence for evolution, wearing embryological character.As a result of in-depth study of multicellular animals in its infancy there are significant similarities.Especially clearly seen similar signs of embryos belonging to the same class or type.Thus, terrestrial vertebrates marked tab gill arches as well as in fish, although in adults they have no functional significance.This suggests that all living organisms have a common origin.It displays the evolution and include the rudiments of man, that is undeveloped parts or organs of the body.The most common ones include the coccyx, which is the triangular bone is formed of several fused vertebrae.Once it forms the tail, however, with the transition to bipedalism I need for it anymore.As a result of this organ in humans it is in its infancy, but its presence confirms the theory of evolution.
Also note atavism.It refers to the appearance of a certain trait that is characteristic of the ancestors, but normally it should not be present in modern humans.For example, this may be a strong hairy, the presence of more than one pair of mammary glands and the like. D.
Note and morphological evidence of evolution.Among them, of particular value are the forms that combine the features of the large systematic units.In addition, scientists have noted that some vertebrates fundamentally similar structure forelimbs, despite the fact that they have different functions.
rich research material for the study of evolution provides a comparison of various natural wildlife areas.The distribution of various kinds and types on the planet and further grouping of geographical conditions clearly reflects the historical development of all living things.
