Answer» Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring. The classic example used to explain the concept of use and disuse is the elongated neck of the giraffe. According to Lamarck\'s theory, a given giraffe could, over a lifetime of straining to reach high branches, develop an elongated neck.
