  • C: Despite his insightful recognition of evolutionary change, Lamarck is chiefly remembered for the flawed mechanism he proposed.
  • D: Lamarck published his evolutionary hypothesis in 1809, coincidentally the year of Charles Darwin's birth.
  • E: Modern scientific understanding, particularly in genetics, affirms the principle of inheritance of acquired characteristics.

Explanation

Lamarck's hypothesis included two main principles: 'use and disuse' Option A and 'inheritance of acquired characteristics' implied in A and the context . He also believed in an 'innate drive to become more complex' Option B . The text states he is remembered for his 'incorrect mechanism' despite visionary recognition Option C . Historically, his hypothesis was published in 1809, the year Darwin was born Option D . However, modern genetics 'refutes this mechanism' of acquired inheritance, making Option E incorrect.
