Which statement about Lamarckian evolution is correct?
A{'text': 'Lamarck rejected the idea that evolution had occurred among living forms', 'label': 'A'}
B{'text': 'Lamarck attributed evolutionary change to use, disuse and inheritance of acquired characters', 'label': 'B'}
C{'text': 'Lamarck first proposed natural selection as the central mechanism of evolution', 'label': 'C'}
D{'text': 'Lamarck argued that large random mutations alone drive the appearance of new species', 'label': 'D'}
Answer & Solution
Correct answer: B. {'text': 'Lamarck attributed evolutionary change to use, disuse and inheritance of acquired characters', 'label': 'B'}
Before Darwin, the French naturalist Lamarck accepted that evolution had occurred but argued that it was driven by use and disuse of organs, with acquired characters such as the giraffe's elongated neck passed to succeeding generations. The chapter notes that this conjecture is no longer accepted.
