Correct answer: B. disuse of wings over many generations
- A. natural selection
- B. disuse of wings over many generations
- C. genetic engineering
- D. mutation only

In Lamarck's scheme, ground living birds stopped flying, their wings weakened from disuse and the reduction was passed on. Today we explain the kiwi's wings through selection, but the question tests the Lamarckian logic itself.

About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
