AP BIOLOGY

Detailed explanation-1: -In the case of the French biologist Jean-Baptiste Lamarck, his name since the end of the nineteenth century has been tightly linked to the idea of the inheritance of acquired characters. This was indeed an idea that he endorsed, but he did not claim it as his own nor did he give it much thought.

Detailed explanation-2: -According to Lamarck, organisms altered their behavior in response to environmental change. Their changed behavior, in turn, modified their organs, and their offspring inherited those “improved” structures.

Detailed explanation-3: -Lamarck is best known for his Theory of Inheritance of Acquired Characteristics, first presented in 1801 (Darwin’s first book dealing with natural selection was published in 1859): If an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring.
