Question

Which animal was used by Lamarck to describe the theory of inheritance through acquired characters?

• A. Dog
• B. Beetle
• C. Giraffe
• D. Monkey

Answer 1

The correct option is C Giraffe

Lamarck's theory of inheritance of acquired characters states that characters acquired by an organism during its lifetime are passed on to the next generation. The development of these characters is based on the use and disuse of organs. The organs which are used extensively develop more as compared to the organs which are not used. This theory was explained with the example of giraffe. According to the theory, giraffes had to stretch their necks in order to eat leaves from tall trees. The increased use of their necks lead to their elongation.
