Solution:
Herbert Spencer $(1820-1903)$ used the words Survival of the Fittest for natural selection. According to it, in the struggle for existence, only those individuals survive which possess the most useful variations. This has been called Natural Selection by Darwin. Hugo de Vries (1901) proposed mutation theory of evolution in his book Species and Varieties-their origin by Mutationson the basis of studies on Evening Primrose (Oenothera lamarckiana). Jean Baptiste Lamarck $(1744-1829)$ proposed the first theory of evolution, called theory of inheritance of acquired characters as well as theory of use and disuse of organs in the book Philosophic Zoologique.
