An example of convergent evolution is
Correct answer: B. Wings of birds and insects
- A. Forelimbs of man and bat
- B. Wings of birds and insects
- C. Darwin's finches
- D. All of the above
Explanation
Despite the different underlying structures, both bird wings and insect wings serve the same purpose of enabling the organisms to achieve powered flight. This similarity in function is due to the shared adaptation of flight for these two groups to their respective environments, even though their evolutionary history and anatomical structures are quite distinct. This is a classic example of convergent evolution.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
