Lamarck proposed the idea of inheritance of acquired characteristics, suggesting that traits acquired during an organism's lifetime could be passed on to its offspring. For example, he believed that if an organism developed a characteristic through use or disuse, such as a giraffe stretching its neck to reach higher leaves, that trait would be inherited by its offspring. This concept was largely rejected by fellow scientists, as it contradicted the emerging understanding of genetics and natural selection, particularly as formulated by Darwin. Instead, it was established that genetic traits are inherited through genes, not through acquired characteristics.

Lamarck proposed the idea of the inheritance of acquired characteristics, suggesting that traits acquired during an organism's lifetime could be passed on to its offspring. For example, he believed that if a giraffe stretched its neck to reach higher leaves, its offspring would inherit a longer neck. This concept was largely rejected by scientists in favor of Darwin's theory of natural selection, which emphasizes genetic variation and survival of the fittest rather than the inheritance of traits acquired during an individual's lifetime.
