Philosophie zoologique

*Philosophie Zoologique*, written by Jean-Baptiste Lamarck in 1809, is a foundational work in evolutionary biology. Lamarck proposed that animals develop new traits based on their needs and the use or disuse of organs, and these traits can be passed on to offspring. He also believed that life evolves through a natural process driven by a desire for improvement. Although some ideas are outdated, Lamarck's work was revolutionary in suggesting that species change over time, emphasizing the importance of adaptation and the dynamic nature of life.
