Hugo Marie de Vries (Dutch pronunciation: [ˈɦyɣoː də ˈvris]; 16 February 1848 – 21 May 1935) [2] was a Dutch botanist and one of the first geneticists.He is known chiefly for suggesting the concept of genes, rediscovering the laws of heredity in the 1890s while apparently unaware of Gregor Mendel's work, for introducing the term "mutation", and for developing a mutation theory of ...
Hugo de Vries wondered what the nature of germ plasm might be, and in particular he wondered whether or not germ plasm was mixed like paint or whether the information was carried in discrete packets that remained unbroken. In the 1890s he was conducting breeding experiments with a variety of plant species and in 1897 he published a paper on his ...
e. Mendelian inheritance (also known as Mendelism) is a type of biological inheritance following the principles originally proposed by Gregor Mendel in 1865 and 1866, re-discovered in 1900 by Hugo de Vries and Carl Correns, and later popularized by William Bateson. [1] These principles were initially controversial.
The modern synthesis[a] was the early 20th-century synthesis of Charles Darwin 's theory of evolution and Gregor Mendel 's ideas on heredity into a joint mathematical framework. Julian Huxley coined the term in his 1942 book, Evolution: The Modern Synthesis. The synthesis combined the ideas of natural selection, Mendelian genetics, and ...
large-scale genetic changes capable of producing a new subspecies, or even species, instantaneously. [1] The historian of science Betty Smocovitis described mutationism as: [2] the case of purported saltatory evolution that Hugo de Vries had mistakenly interpreted for the evening primrose, Oenothera. [2]
1889: Hugo de Vries postulates that "inheritance of specific traits in organisms comes in particles", naming such particles "(pan)genes". [2] 1900: Mendelian principles are "rediscovered" and published by 3 botanists independently, Hugo de Vries, Carl Correns and Erich von Tschermak-Seysenegg, setting off a Mendelian revolution
Genetics and the Origin of Species is a 1937 book by the Ukrainian-American evolutionary biologist Theodosius Dobzhansky. It is regarded as one of the most important works of modern synthesis and was one of the earliest. The book popularized the work of population genetics to other biologists and influenced their appreciation for the genetic ...
Hugo de Vries characterized his own version of pangenesis theory in his 1889 book Intracellular Pangenesis with two propositions, of which he only accepted the first: I. In the cells there are numberless particles which differ from each other, and represent the individual cells, organs, functions and qualities of the whole individual.
