Charles Robert Darwin, the biologist, the psychologists, philosophist, pioneer of evolutionism who put forward the doctrine of biological evolution, which destroys all kinds of idealistic theology and species invariance.
Long before Darwin, many scientists expressed themselves on the a gradual and continuous change in all species of plants and animals, but it was Darwin who put forward a completely new hypothesis regarding living nature, generalizing individual evolutionary ideas into one, the so-called theory of evolution, which was the most widely spread in the world.
Darwin suggested that in competition among animal populations, only those will survive that have properties of benefits under given specific conditions, allowing producing offspring as well. His theory is based on three principles: a) heredity and variability; b) the struggle for existence; c) natural selection.
Variability is an inalienable attribute of all living things. Despite the similarity of living organisms of the same species, two completely identical individuals cannot be found within the population. This variation of features and properties creates the advantage of some organisms over others.
A certain variability, or adaptive modification, is the ability of individuals of one species to react in an identical way to changes in the environment. Such group changes are not inherited, so they can not supply material for evolution..
The core principle of natural selection has the following implications: Organisms have a tendency to overproduce while living space and food are limited, so that creatures must “fight for survival.” Variants exist in individuals within the same population, and individuals with favorable variations that adapt to the environment will survive and multiply offspring, while individuals without favorable variability will be eliminated. His natural selection principle is based on the prevailing “amalgamation genetic” hypothesis at that time
A COMPARATIVE ANALYSIS OF TWO THEORIES
1) the process of the Universe and the origin of life on Earth.
The evolutionary model is based on the principle of gradual variability and believes that life on Earth has reached a complex and highly organized state in the process of natural development. Creationist model highlights a special, initial moment of creation, when the most important inanimate and living systems were created in a complete and perfect form.
2) Driving forces.
The evolutionary model asserts that the driving forces are the immutable laws of nature. Thanks to these laws is the Genesis and improvement of all living things. Here evolutionists include laws of biological selection, based on the struggle of species for survival.
3) Driving forces and their manifestation at present.
Evolutionary model: due to the immutability and persistence of the driving forces, the natural laws that created all living things are still in force today. As a derivative of their actions, evolution is happening and haunt her.
