Darwinism and the theory of evolution are by no means equivalent conceptions.
The theory of evolution was propounded before Charles Darwin’s time, by Lamarck (1809) and Geoffroy de Saint-Hilaire.
In 1859, Darwin gave it a new form by explaining the origin of species by means of natural selection.
According to his theory, the breeding of new species depends on the survival of the fittest in the struggle for existence.
The Darwinian theory of selection is Darwinism—adhering to the narrower, and accurate, sense of the word.
As a theory, it is scientifically inadequate, since it does not account for the origin of attributes fitted to the purpose, which must be referred back to the interior, original causes of evolution.
Haeckel, with other materialists, has enlarged this selection theory of Darwin’s into a philosophical world-idea, by attempting to account for the whole evolution of the cosmos by means of the chance survival of the fittest.
This theory is Darwinism in the secondary and wider sense of the word. It is that atheistic form of the theory of evolution which was untenable to the other theorists.
The third significance of the term Darwinism arose from the application of the theory of selection to man, which is likewise impossible of acceptance to the other side.
This is the use of the word that rests on an evident confusion of ideas that is being set aside and disregarded by the proponents of the theory of creation.
On the other hand, the opposing theory of creation from the bible of the religious church limits the origin of the human specie from only two: the very popular adam and eve which is untenable to the oppositors.
