A major fault, for example, is the fact that, along with the materialist principle, Darwin introduced into his theory of evolution reactionary Malthusian ideas.

Progressively thinking biologists, both in our country and abroad, saw in Darwinism the only right road to the further development of scientific biology.

Darwinism as presented by Darwin contradicted idealistic philosophy, and this contradiction grew deeper with the development of its materialist teaching.

Agricultural practice served Darwin as the material basis for the elaboration of his theory of Evolution, which explained the natural causation of the adaptation we see in the structure of the organic world. That was a great advance in the knowledge of living nature.
