Worked practice questions

The **mutation theory of evolution** was proposed by:

  1. Hugo de Vries (1901, working with *Oenothera*)
  2. Lamarck
  3. Darwin
  4. Mendel
Show answer and solution

Correct answer: A. Hugo de Vries (1901, working with *Oenothera*)

de Vries observed sudden discontinuous variations in evening primrose (*Oenothera lamarckiana*) and proposed that such mutations — large, sudden, heritable changes — drive evolution. Contrasted with Darwin's emphasis on small gradual variations.
