The organs which are similar in function but differ in structure are called:
Correct answer: A. Analogous organs
- A. Analogous organs
- B. Homologous organs
- C. Convergent evolution
- D. Divergent evolution
Explanation
Analogous organs have a similar function but with different embryonic origins and structures. Homologous structures share a similar embryonic origin and but have the different functions. For example, the bones in a whale's front flipper are homologous to the bones in the human arm. However, a butterfly's or a bird's wings are analogous in comparison but not homologous.

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.
