Lamarckism is the once popularly accepted, but since mainly discredited, idea that an organism can pass on characteristics that it acquired during its lifetime to its offspring. It is named after the French biologist Jean-Baptiste Lamarck, who incorporated the action of soft inheritance into his evolutionary theories and is often incorrectly cited as the founder of soft inheritance. It proposed that individual efforts during the lifetime of the organisms were the main mechanism driving species to adaptation, as they supposedly would acquire adaptive changes and pass them on to offspring. After publication of Charles Darwin's theory of natural selection, the importance of individual efforts in the generation of adaptation was considerably diminished. Later, Mendelian genetics supplanted the notion of inheritance of acquired traits, eventually leading to the development of the modern evolutionary synthesis, and the general abandonment of the Lamarckian theory of evolution in biology. In a wider context, soft inheritance is of use when examining the evolution of cultures and ideas.
