In what way does Buck's behavior evolve throughout the story?

Buck's evolution throughout the story is marked by his increasing ability to trust his instincts and skills, which is essential for survival in the harsh wilderness. Initially, Buck is a domesticated dog accustomed to a life of comfort and dependence on humans. As he faces the challenges of the wild and the brutal realities of sled dog life, he gradually sheds these learned behaviors and begins to tap into his primal instincts.

This transformation is pivotal to the narrative, as it signifies Buck’s journey from domestication to embracing his ancestral roots. He learns to read his environment, understand the dynamics of pack life, and rely on his physical capabilities. This reliance on instinct and skill ultimately leads him to become a leader in the wild, showcasing his full potential and true identity as a creature of nature.

The other options don't capture the essence of Buck's growth; rather, they reflect a misunderstanding of his character development. Buck does not grow more reliant on humans, avoids making decisions, or become fearful of the wild, as these would be counter to his journey toward independence and self-discovery. His progression is about embracing freedom and raw nature, and learning to trust himself above all else.
