What is the significance of the "call of the wild"?

The significance of the "call of the wild" primarily lies in its representation of Buck's instinctual drive to return to his wild nature. Throughout "The Call of the Wild," Buck undergoes a profound transformation from a domesticated pet to a primal creature, deeply reconnecting with his ancestral instincts. This call is not merely a yearning for freedom but a compelling force that draws him back to the natural world where he can fully embrace his identity as a wolf and thrive in the wilderness.

As Buck hears the call, it evokes a deep, primal response within him, awakening the traits of survival and instinct that have been dormant during his time as a household pet. The call serves as a metaphor for the innate instincts that all animals possess, suggesting that, beneath the layers of domestication, there exists a powerful drive to return to one’s true nature. This journey to rediscover his wild self is central to the narrative and emphasizes themes of evolution, survival, and the connection between animals and their environment.
