Throughout the millennia the great minds tried to solve the mystery of emergence of the person on the earth. There are no concrete statements in this respect, scientists still argue. Select three main theories: Darwinism, creationism and theory of external intervention.
Instruction
1. The English naturalist Charles Darwin in the book "The Origin of Species by Natural Selection" (1859) summed up the numerous statements of scientists of the 18th age of rather evolutionary theory of origin of mankind. Four factors of evolution are considered as the basic principles of Darwinism: - hereditary variability - transfer of the genetic code through generations, emergence of differences in the subsequent crossings of different types; - fight for existence - development of ability to adapt to the changing environment; - natural selection - increase in number of individuals with most developed fitness to the environment of dwelling; - isolation - reproduction of a look within a dwelling area.
2. According to Darwinism, the person occurred from antropoidny ancestors - anthropoids - by gradual modification. The constant variability and danger of the environment forced the highest primacies to learn to adapt: to go directly, to defend from wild animals by means of a stick or a stone, to use them as an instrument of labor, etc. As confirmation of the theory of Darwin archeological excavations, researches in the field of genetics and other are offered. However some anthropologists (for example, B.F. Porshnev) called in question development of the person on the basis of the need for work. Many monkeys are able to handle sticks and tableware also now, but they do not turn into people. There are left questions without answers that allows scientists to reflect further.
3. According to the theory of creationism (Latin of creatio - creation), the person was created by the principal reason - God. At each religion the options of creation of the world. The Christian theory when God for several days created the sky and the earth, and then the first person - Adam is most distributed. That it was not boring for him, God created Eve - the first woman. The theory of divine creation has no scientific evidence as it cannot be confirmed with an experiment. Some theologians recognize evolution across Darwin, however insist that on everything there was a will of the Creator. Others completely deny Darwinism, resorting as proofs that the person from all animals is distinguished by existence of soul and independent way of thinking which could not develop in the course of evolution - they were put initially by the highest being.
4. If to consider the theory of creation of the person the principal reason without the religious background, there is the following theory - interventions from the outside. Her adherents consider that aliens as an experiment occupied the earth people and periodically arrive to look at the creation. As confirmation researches in the field of the UFO are used, allegedly civilizations from other planets send to mankind signs in the form of large-scale drawings on the earth, etc.
5. Disputes about existence of Atlantis - the sunk state which was created by the same aliens do not stop, and then destroyed because of constant failures in the planned program of human development. All taking place cataclysms are attributed to the principal reason as signs of prevention: we will treat you in the same way if you do not understand point of the existence. Some scientists consider that Leonardo da Vinci's inventions were prompted to it by alien beings. According to the theory of external intervention, the Egyptian pyramids, Grand Canyon in America and other miracles were also made the principal reason. The ancient person was just not capable of it.
