Lamarckism was introduced by Jean-Baptiste de Monet Lamarck between 1744 and 1829. This idea suggested that any changes that happen to an organism’s body during its lifetime are passed on to its children. For instance, if an organ is frequently used and develops, this change can be inherited by future generations.
