G. de Vries is a notable figure in the field of genetics, particularly known for his work on the concept of mutation. He was a Dutch botanist and geneticist who conducted significant research in the early 20th century. His studies on the evening primrose, Oenothera lamarckiana, led to the discovery of new traits arising in plants, which contributed to the understanding of genetic variation. In addition to his research, G. de Vries is recognized for coining the term "mutation" to describe these sudden changes in traits. His work laid the foundation for modern genetics and influenced other scientists, including Gregor Mendel, whose earlier work on inheritance patterns was pivotal in the field.
