Lamarck proposed the idea of the inheritance of acquired characteristics, which suggested that individuals could acquire traits during their lifetime and pass them onto their offspring. This idea was eventually disproven by the discovery of genetics and the understanding of how traits are passed down through genes. However, Lamarck did contribute to the development of evolutionary theory by proposing a mechanism for how species changed over time, even if his proposed mechanism was ultimately incorrect.
