Jean baptist lamarck was the first person to propose the theory of evolution. He thought that at same point of time in the history the size of giraffe was equal to the height that of deer. Because of continuous streching of necks. Such characters that are developed during the lifetime of an organism are called acquired characters. Lamarck proposed that these acquired characters are passed on its offsprings.i.e, next generation and proposed the theory of inheritence of acquired characters.
