Correct answer: B. Lamarckism
- A. Darwinism
- B. Lamarckism
- C. Natural selection
- D. Special creation
Explanation
According to the Lamarck, the development and degeneration of organs will be based on the use and disuse of organs respectively. For example, coccyx (tailbone) because of not using this organ it has become vestigial.

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.

The following observations refer to evolution: I. Inherited variations that are 'favored' in particular environments are passed on. II. There is a struggle for existence. III. In time, 'favored' inherited variations may accumulate causing gradual changes in the organism. IV.
