Which of the following are important points of Lamarck's theory?

Explanation

Lamarck's theory of evolution is based on two main ideas: The use and disuse of organs: Lamarck believed that the organs that are used more often become stronger and more developed, while the organs that are used less often become weaker and less developed. He believed that this could lead to changes in the organism's physical appearance over time. The inheritance of acquired characteristics: Lamarck believed that the changes that an organism makes to its body during its lifetime can be passed on to its offspring. For example, he believed that giraffes had evolved long necks because their ancestors had to reach for food high up in trees. Therefore, both A and B are correct. Lamarck did not give the theory of natural selection.
