Question

What are the principles of Lamarck’s theory on which the inheritance of acquired characters is based?

Answer

Lamarck’s theory on the inheritance of acquired characters is based on two main principles:

1. The principle of use and disuse, which states that organs or traits that are used more often will become more developed, while those that are not used will deteriorate over time.
2. The principle of inheritance of acquired characteristics, which suggests that these acquired traits can be passed on to offspring, leading to evolutionary change over time.
