Which aspect of life does Buck's journey ultimately highlight?

Buck's journey in "The Call of the Wild" emphasizes the struggle between civilization and the wild because it illustrates his transformation from a domesticated pet to a primal creature embracing his inherent instincts. Throughout the story, Buck experiences a loss of his comfortable life in a human household and is thrust into the harsh realities of the wilderness, where survival depends on embracing animalistic traits.

As he navigates this new world, Buck encounters both human civilizations, which represent order and control, and the raw forces of nature that signify freedom and instinctual survival. His evolution culminates in his ultimate acceptance of his wild ancestry, illustrating how resilience, adaptability, and the call of the wild prevail over the constraints of civilization. This fundamental theme underscores the tension between these two worlds and highlights Buck's reclaiming of his true nature amidst the encroachment of society and its norms.
