Explain how the beginning of The Call of the Wild illustrates the idea of "survival of the fittest". Use
an example (a quote) from the text to justify your answer. (One paragraph)
Buck's first encounters with the kidnapper reveal that Buck's instinct for self-preservation has not been tempered by his protected lifestyle. Buck, who has always cared for and protected his humans, knows immediately that this is a person whom he can and should bite to protect himself. With this transformation, London suggests that Buck slips too easily into the role of aggressor to have been entirely tame in the first place.
