The correct answer to this open question is the following.
We are referring to Jack London's history "Call of the Wild," written in 1903. It is a classic story of naturalism that reflects the endurance in the wildlife. Ine clear example of the story is the constant survival of the fittest and the struggle for being alive, the constant fight for existence under difficult conditions. The story transmits so much realism of the harsh condition in the wilderness with the narration of Buck, the main dog in the story.
