The essay describes the development of Hugo de Vries's thinking on heredity from the publication of his Intracellulare Pangenesis in 1889 to the publication of Die Mutations-theorie, Volume 2, in 1903. De Vries's work in the 1890s can be characterized as an attempt to defend his theory of pangenes, …

Hugo Marie de Vries. 1848-1935. Dutch Botanist. Hugo Marie de Vries was a Dutch botanist whose work with plant species led him to rediscover Gregor Mendel's theories of heredity, and brought his concept of mutation into evolutionary theory..

6 de sept. de 2011 · Introduction. In the history of evolutionary biology, Hugo de Vries is known as a proponent of the mutation theory of evolution, in which new species are believed to arise by single mutational events (de Vries 1901–1903, 1909, 1910).This theory is based on the breeding experiment he conducted for 13 years with the evening primrose Oenothera lamarckiana and its mutant descendants.

DeVries, Hugo. (1848-1935) Dutch botanist famous for his contributions to genetics. He rediscovered the results first obtained by Mendel and described genetic changes in his plants. Based on his observations, DeVries argued that individual mutations had wide-ranging effects and could cause speciation in a single step; however, T. H. Morgan ...
