An example of convergent evolution is best represented by which one of the following?
Correct answer: C. Wing of Hawkmoths:The wing of hawks
- A. Teeth of domestic dog:Teeth of a wolf
- B. Wings of Geospiza magnirostris:Wings of Geospiza fortis
- C. Wing of Hawkmoths:The wing of hawks
- D. All of these options are correct
Explanation
Convergent evolution involves the independent development of similar structures in organisms that are not directly related. It is represented by analogous organs. Analogous organs are structures that are different in their basic structure and developmental origin but appear similar and perform similar functions. This relationship between the structures of different groups of animals due to their similar functions is called analogy or convergent evolution. In this question, "Hawkmoth" and "Hawk" are different in basic structure but perform the same function, which is flight. Both are flat and well-adapted to flight.

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.
