Two key concepts form the foundation of Lamarck’s theory of evolution: Organ use and disuse: According to Lamarck, the more frequently used organs get stronger and more developed, while the less frequently used organs get weaker and less developed. He thought that over time, this might cause the organism’s physical characteristics to change. The transfer of learned traits: According to Lamarck, an organism’s physical changes over the course of its lifetime can be passed on to its progeny. For instance, he thought that because giraffes’ ancestors had to reach high in trees for food, they developed long necks.
