Why did Hugo De Vries propose a theory about mutation?
Hugo de Vries proposed his theory of mutation in the early 20th century as a way to explain the sudden changes he observed in the characteristics of certain plant species, particularly the evening primrose. He believed that these abrupt changes, or "mutations," represented a new mechanism of evolution, distinct from the gradual changes emphasized by Darwin's theory of natural selection. De Vries's work contributed to the understanding of heredity and variation, laying the groundwork for modern genetics. His theory highlighted the role of genetic mutations as a source of new traits that could drive evolutionary change.
