Which one of the following pairs represents an analogous feature?
Correct answer: C. Insect wing and bat wing
- A. Elephant tusks and human incisors
- B. Teleost erythrocyte and mammalian erythrocyte
- C. Insect wing and bat wing
- D. Mole forelimb and bird wing
- E. None of the above
Explanation
Option A: Elephant tusks and human incisors are homologous structures, meaning they have the same evolutionary origin but different functions. Option B: Teleost erythrocyte and mammalian erythrocyte are both types of red blood cells, but they have different structures. Option C: Analogous features are structures that have similar functions but different evolutionary origins.In the case of insect wings and bat wings, they both have the same function of flying, but they evolved independently from each other. Insect wings evolved from modified leg segments, while bat wings evolved from modified fingers. Option D: Mole forelimbs and bird wings are both forelimbs, but they have different functions (mole forelimbs are used for digging, while bird wings are used for flying).

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.
