How did de Vries explain evolution?
De Vries's theory was one of the chief contenders for the explanation of how evolution worked, leading, for example, Thomas Hunt Morgan to study mutations in the fruit fly, until the modern evolutionary synthesis became the dominant model in the 1930s.
May 17, 2024 · De Vries’ research into the nature of mutations, summarized in his Die Mutationstheorie (1901–03; The Mutation Theory), led him to begin a program of plant breeding in 1892, and eight years later he drew up the same laws of heredity that Mendel had.

Advanced at the beginning of the 20th century by Dutch botanist and geneticist Hugo de Vries in his Die Mutationstheorie (1901–03; The Mutation Theory), mutation theory joined two seemingly opposed traditions of evolutionary thought.

Sep 6, 2011 · We have first indicated that the root of the currently burgeoning field of plant genomics goes back to Hugo de Vries, who proposed the mutation theory of evolution more than a century ago and that he unknowingly found the importance of polyploidy and chromosomal rearrangements in plant speciation.

Nov 21, 2023 · Hugo de Vries was a Dutch botanist who forwarded an influential mutation theory of evolution. He defined mutation as an observable change that was passed from one generation to the next.
De Vries based this "theory of mutation" on work he did using Oenothera lamarckiana - the evening primrose. He observed that the original plant would occasionally have offspring with significant phenotypic differences such as leaf shape and plant sizes.
