Option D: Hugo de Vries

Detailed Solution:

The correct answer is “Hugo de Vries”.
Hugo de Vries, a Dutch botanist and geneticist, proposed the mutation theory of evolution in the early 20th century. His theory states that new species can develop from existing species after sudden mutations.

De Vries believed that these mutations were caused by major differences in the population, not minor variations. He also thought that mutations were random, inheritable, and discontinuous variations that could serve as raw material for evolution.
