* Synthetic Theory of evolution
The Austrian botanist
Gregor Mendel discovered the laws of genetics, but the discovery remained ignored for thirty years. When his work was known in the beginning of the twentieth century, came into collision with Darwinism, until the 1930s achieved a synthesis between the theories of Darwin and Mendel, through the work the Ukrainian geneticist Theodosius Dobzhansky who led the so-called synthetic theory of evolution or neo-Darwinism.
The
amendments are those changes or alterations of an individual, as that will not affect the genetic material passed to offspring.
Mutations are changes that, for various causes such as radiation, certain chemicals, etc.. reach and may affect the genetic material transmitted to offspring.
The synthetic theory of evolution can be summarized in two points:
1) In all living things there is
genetic variability caused by mutations may be favorable or unfavorable neutral. Genetic recombination caused by the union of the egg il'espermatozoide in sexual mating.
2) The
natural selection removes mutations and unfavorable combinations eliminates individuals who possess characteristics with a low adaptive value. *Humanisation in the genetic process from a cultural and social standpoint.
The human being is the 'cultural animal, the animal learns that the socially their behavior.
Higher animals possess rudimentary but it is a culture among humans where the cultural organization's existence reaches its maximum level.
