The importance of marxism as well as of Darwinism consists in their following out the theory of evolution. Charles Robert Darwin and Karl Heinrich Marx dominated the human mind in the second half of the 19th century making Marxism and Darwinism much debated theories. Darwinism follows the domain of the organic world, and Marxism follows the domain of society. Earlier, Hegel made it the central point of his philosophy. Darwin's The Origin of Species was immediately accepted as a strongly proved truth, linking the theory of evolution with Darwins name. Darwin discovered the mechanism of animal development, and he showed that under certain conditions some animal kinds will necessarily develop into other animal-kinds. Darwinism provided the ideology behind Marxism and teenage nihilism. Communism differs from socialism because it contemplates revolutionary social change and not in just electoral politics. Socialism as a political doctrine that not accept individualism as the foundation for economic and social life.
Karl Marx discovered the propelling force, the cause of social development. Marx did not have to prove that such a development was taking place; every one knew that from the most primitive times new social forms ever supplanted older. In Marxism and Darwinism, Marxism owes its importance and position to the role it takes in the proletarian class struggle. Darwinism deals with a new scientific truth which has to contend with religious prejudices and ignorance. Anton Pannekoek, a Darwinist-Marxist thinker, sums this up in his book Marxism and Darwinism published early in the 20th century.
The reason for Marxism's attraction to Darwinism is the apparent support Darwinism gives to atheism. Marxist ideas claim that each historical period has a distinct mode of production that rests upon particular forces - or technological organization - of production and distinct ways of organizing social relationships between people in the economy. Contemporary evolutionists also note the strong bond between Marxism and Darwinism.
