English naturalist, born in a family of doctors. After he had renounced his studies of air max bw pas cher medicine, Charles Darwin went to the University of Cambridge to be a Anglican priest. But, in 1831, he started a long journey of five years around world, in South America and in the Pacific Islands, as naturalist on the research ship « Beagle ». During this period, he collected an enormous quantity of biological and geological observations. The natural phenomena he noted (distribution of fossils) persuaded him that the only creation cannot explain them and that animal and plant species are not immutable.
Established in London, Charles Darwin published the account of his journey, « Voyage of the Beagle » (1839), and started to exploit the mass of data he brought back from it. In 1843, he settled definitively in Downe, in the still of the London country, to keep on with his research. He took an interest in Malthus and in the practices of selection used by the stockbreeders.
By analogy with the artificial selection, Charles Darwin air max femme pas cher discovered the mechanism of the natural selection. The individuals of a species who are the best adapted to their environment survive, reproduce; the others disappear. That way, only the variations that are useful for species are transmitted by an individual to its descendants. These new characteristics become thus gradually dominant. Consequently species are not fixed, as it was until then believed in coherence with the Bible. The main point of the Darwin’s theory is exposed in « Origins of Species » (1859), in which the general evolution and the principles of selection are described, and in « The Descent of Man » (1871). It is necessary to specify that only the modern genetics, which developed air max classic starting from work of Mendel (1822 1884), has validated the theory of Darwin and has explained the transmission modes of the hereditary characters.
Karl Marx (1818 1883) was one of the first philosophers to become aware of the importance of the Darwin’s works. According to Sigmund Freud (1856 1939), Charles Darwin inflicted a deep narcissistic wound on man by showing that he is neither a God’s creature, nor the elected species of nature, but only the fruit of a long evolution in the animal kingdom. The theory of evolution destroyed the argument of purpose, of the divine will, according to which the beauty of world and the perfection of the living organisms show proof of the Creator’s existence.
In addition nike air max pas cher to his theory nike air max classic bw about evolution and air max tn selection, Charles Darwin produced a scientific work of the highest importance. Christian in his youth, Charles Darwin evolved gradually nike air max 90 pas cher to deism, then towards agnosticism at the end of his life.
