Jean-Baptiste de Lamarck

Jean-Baptiste de Lamarck was a French naturalist and early proponent of evolutionary theory, best known for his ideas on the inheritance of acquired characteristics, which he proposed in the early 19th century. His work laid the groundwork for later evolutionary biology, although his ideas were largely overshadowed by those of Charles Darwin. Lamarck's theories emphasized the gradual change of species over time, suggesting that organisms could adapt to their environments and pass on these adaptations to their offspring. Despite the eventual decline of his theories in favor of Darwin's concept of natural selection, Lamarck remains a significant figure in the history of biological thought.
