Darwin’s theory lacked an input of modern concepts of genetics and the mechanisms how characters appear and persist in a population. The rediscovery in 1900 of Mendel’s theory of heredity, by the Dutch botanist and geneticist Hugo de Vries and others, led to an emphasis on the role of heredity in evolution.
