What is mutation theory?
When did mutation theory start?
Why is mutation theory important?
Mutation theory, idea that new species are formed from the sudden and unexpected emergence of alterations in their defining traits. 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.

Abstract. Mutation is the engine of evolution in that it generates the genetic variation on which the evolutionary process depends. To understand the evolutionary process we must therefore characterize the rates and patterns of mutation.

Evo 101. Mutations. Mutations are changes in the information contained in genetic material. For most of life, this means a change in the sequence of DNA, the hereditary material of life. An organism’s DNA affects how it looks, how it behaves, its physiology — all aspects of its life.
Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur. In this tutorial, we’ll explore: DNA and the molecular basis of mutations; types of mutations; causes of mutations; effects of mutations; a case study of the effects of mutation; the random nature of mutations
Sep 6, 2011 · 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 ).

Mutations are changes in the genetic sequence, and they are a main cause of diversity among organisms. These changes occur at many different levels, and they can have widely differing...
A mutation is a change in the sequence of an organism's DNA. What causes a mutation? Mutations can be caused by high-energy sources such as radiation or by chemicals in the...
