Solution (By JKSSB Mock Tests)
Charles Darwin proposed the theory of evolution by natural selection, emphasizing that organisms with favorable variations are more likely to survive and reproduce. Hugo de Vries, a Dutch botanist, proposed the mutation theory of evolution based on his work on evening primrose, stating that evolution occurs through sudden, large mutations (saltations). Jean-Baptiste Lamarck proposed the theory of inheritance of acquired characters, based on the use and disuse of organs (e.g., giraffe's neck). All statements are correct.
