Answer and Explanation:
According to this theory, the young of a species may inherit certain physical characteristics which their parents acquired in the course of their daily lives. According to Lamarck, modern giraffes evolved from short-necked ancestors. The long necks develop as a result of stretching to reach the leaves of tall trees. The offspring of these giraffes inherited the long necks.
Lamarck's assumption of acquisition of characteristics by individuals in the course of their lifetimes is true. However, the passing of these traits to their offspring is not true. Acquired characteristics do not cause any alteration whatsoever in the hereditary information contained in the chromosomes. This theory is therefore not valid.
