How does Buck's character change throughout the story?

Buck's character transformation is a central theme in "The Call of the Wild." Throughout the story, he evolves from a domesticated pet enjoying the comforts of home to a strong, independent creature that embraces his ancestral instincts. This growth reflects a deepening connection to his primal nature, driven by the harsh realities of survival in the wilderness.

As Buck faces various challenges in the brutal environment of the Yukon, he learns to trust his instincts rather than rely on the comforts of human companionship. This transformation is marked by moments when he experiences awakening memories of his wild ancestors and instincts, such as his developing skills in hunting and fighting. Rather than becoming more dependent on humans or seeking revenge for his mistreatment, he ultimately sheds his domesticated persona and fully embraces the call of the wild, reflecting a shift toward a more instinctual and powerful version of himself.

This journey emphasizes the theme of evolution and the inherent struggle between civilization and nature, showcasing Buck's ultimate return to his wild roots as a symbol of strength and resilience.
