True. Jean-Baptiste Lamarck, a French biologist, proposed the idea of "use it or lose it" as part of his theory of inheritance of acquired characteristics. According to Lamarck, organisms can acquire certain traits or characteristics through their use or disuse, and these acquired traits can be passed on to the next generation.
True. Jean-Baptiste Lamarck, a French biologist, proposed the theory of inheritance of acquired characteristics, which included the idea of "use it or lose it." According to Lamarck, organisms can acquire new traits or lose existing ones based on their use or disuse during their lifetime. These acquired traits could then be passed on to future generations. This concept is also often referred to as Lamarckism. While Lamarck's theory has been disproven by modern scientific understanding, it was an influential idea in the early development of evolution theory.
