Differentiate between Lamarckism and Darwinism with the help of examples.

Lamarckism and Darwinism are two fundamental theories in the study of taxonomy and evolution that explain how species change over time. Both theories have significantly contributed to our understanding of the evolutionary process, but they differ in their principles and mechanisms.

Lamarckism:  
Lamarckism, proposed by Jean-Baptiste Lamarck, is based on the principle of "inheritance of acquired characteristics." Lamarck suggested that organisms adapt to their environment through the use or disuse of certain traits, and these adaptations are passed on to their offspring. According to Lamarck, environmental changes directly influence an organism's behavior, which leads to physical modifications. These modifications are heritable.

For example, Lamarck explained the long necks of giraffes by stating that ancestral giraffes stretched their necks to reach higher branches for food. Over time, this effort resulted in elongated necks, which were then inherited by subsequent generations. ____ _______ __________ __________ ____ __________.
