Question

Give salient features of the theory of inheritance of acquired characters.

Answer 1

1. Environmental effect: Changes in the environment create new needs in organisms.
2. Use and disuse of organs: Continuous use of an organ makes it more developed, while disuse causes it to become weak or degenerate.
3. Acquired characters: Organisms develop new characters during their lifetime due to environmental changes and new needs.
4. Inheritance of acquired characters: These acquired characters are passed from parents to offspring.
5. Formation of new species: The accumulation of acquired characters over several generations results in the formation of new species.
