Which of the following are important points of Lamarck's theory?
Correct answer: D. Both A and B
- A. Use and disuse of organs
- B. Inheritance of acquired characteristics
- C. Natural selection
- D. Both A and B
Explanation
Lamarck's theory of evolution centers on two main ideas: the use and disuse of organs and the inheritance of acquired characteristics. He believed that organs change based on their usage and that these changes are inheritable. Option D is correct because it includes both of these principles. Option C is incorrect, as it refers to natural selection, a concept introduced by Darwin, not Lamarck.

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.
