Lamarck explained the loss of functional eyes in cave dwelling animals as the result of
- A. sudden mutation
- B. natural selection
- C. hybridisation
- D. disuse over many generations
Explanation
By his law of use and disuse, an organ that stops being used wastes away and the loss is then inherited. Modern genetics rejects the inheritance, but disuse was Lamarck's consistent explanation for disappearing structures.
