Based on a rich factual material, starting with the artificial selection made from man's multi-secular practice, Charles Darwin grounded the conception of evolution of animal and plant species, evolutionism. On the basis of his doctrine stays the conception that man manages through artificial selection to create new varieties and breeds of animals, whose characters can be transmitted by crossing and can be fixed on the descendants. So does the natural selection too, but slower and with the same results. So appear new species capable of surviving and transmitting characters. The underlying cause is the struggle for existence, imploying evolutionary the species, according to the survival of the fittest.
