    Darwin postulates
    Darwin stated that variations are small and direction less hence evoluation was a gradual process
    In a population variations exist which are heritable hence resource utilisation become better for few
    Some individuals which are best suited to the changing environment and enabled to survive in the natural conditions outbreed the others which are less endowed to the natural conditions
