Even in ancient times people have found the remains of strange beasts.Giant dinosaur bones, skull, saber-toothed tigers and mammoths suggests that the land had been previously inhabited by several other animals and plants than those that we can see today.In 1575, a scientist from France, Bernard Palissy was an inventory found fossils, comparing them with the structure of the body of modern organisms.Being unfamiliar with the concept of what is evolution, it nevertheless found that the remains do not belong to any of the living organic forms.Thus, he concluded that species are not immutable.

Darwin in the XIX century did not discover this phenomenon, and tried to explain what evolution is and how it happens.His merit is that he has put forward and proved the theory of natural selection.With climate change and the environment, and there are periods in the history of the globe, there are many, there is a process of sifting the weak, not adapted to the changing conditions of the species giving way to new and more successful life forms.The evolutionary process operates within a species, as a stronger individual leaves behind descendants, and weaker - dies, and not continue the race.

What is evolution - this even before Darwin knew the scientists involved in embryogenesis, that is investigated fetal development.The Latin term «evolutio» (deployment) oppose each Latin word - «revolutio» (revolution).Watching from human embryos the gills are replaced by lungs, evolutionists believed that the structure of the phases in the life of a fertilized egg laid down initially, and only gradually appear and revolyutsionisty defended the opposite point of view: the embryo is transformed to the "empty" place.

However, it was far from controversy in the scientific world of everyday life.While theorists embryogenesis broke spears, Darwin stated publicly that this evolution in nature.He proved that all life on Earth developed from simple to complex, and that the history of our planet there are many dead-end branch that became extinct, unable to adapt to changing conditions.This caused an uproar among creationists, who believed that God created all living things for the days of creation of the world, and in the form in which we see today.

organic evolution clearly indicates that the man stood out from the great apes through natural selection.Now, in the XXI century, no one disputes that evolution - a proven fact.The fossil record - layers of the earth's species - suggests that amphibians appeared in Devon, reptiles - in Carbone and animals - in the Triassic.Moreover, now that in a globalized world where animals and plants artificially relocated to other parts of the world, in a warming and human activities, we can see that natural selection continues to operate.

Even a superficial acquaintance with the history of mankind generates confidence among the species Homo sapiens as a community and evolutionary changes occur.Immediately after Darwin's discoveries in the science of sociology penetrated the theory that the evolution of society passes on similar laws, as in the wild.Comte believed that the main parameters of social development is the knowledge and technological progress.Spencer also saw the evolution in the complexity of the structure of society, which play a very important individual rights.A determining factor in social change in favor of Marxist theory productive relationship.
