All of the following ideas were proposed by Lamarck, EXCEPT:
Correct answer: D. Over production leads to evolution
- A. Use and disuse of organs
- B. Acquired characters are inherited by the offspring
- C. Organs not used will become vestigial
- D. Over production leads to evolution
Explanation
Overproduction of offspring leading to a struggle for existence is part of Darwin's theory of natural selection, not Lamarck's. Use and disuse, inheritance of acquired characters and the loss of unused organs are all Lamarck's own ideas.

About Lamarckism
Lamarckism explains evolution through environmental influence, use and disuse of organs, and the inheritance of acquired characteristics. It differs from Darwinian natural selection because Lamarck proposed that organisms develop useful traits during their lifetime and pass them on, a view not supported by modern genetics.
