The views of Hugo de Vries and others about the importance of saltatory variation, the soundness of which was still not generally accepted in 1910, may be gathered from the article Mendelism.

He was a board member for the " Swedish Society for Racial Hygiene " ( founded 1909 ), which endorsed mendelism at the time, and contributed to the topic of contraceptives around 1910.

He believed that natural selection and Mendelian genetics were compatible, and referred to the theoretical work of Sewall Wright, R . A . Fisher, and J . B . S . Haldane, which proved that quantitative traits and natural selection were compatible with Mendelism.

Among these theories were neo-Lamarckism ( which merged certain aspects of Lamarck's theory of acquired characteristics with certain aspects of Darwinian evolution ), orthogenesis ( " straight-line " evolution, which talked about evolution towards a specific goal by forces within the organism ), and the discontinuous variation of Mendelism and Hugo De Vries'mutation theory.

These and other early discoveries of genetics are often framed relative to a controversy between, on the one hand, early geneticists the " Mendelians " including William Bateson, Wilhelm Johannsen, Hugo de Vries, Thomas Hunt Morgan, and Reginald Punnett, who advocated Mendelism and mutation, and were understood as opponents of Darwin's original view, and the biometricians and their allies, who opposed Mendelism and were more faithful to Darwin's original vision.
