What does Buck eventually prioritize over his past comforts?

Buck ultimately comes to prioritize his instinctual connection to the wild because throughout "The Call of the Wild," he undergoes a profound transformation influenced by his experiences in the wilderness. Initially accustomed to a life of domestic comfort and human companionship, Buck gradually taps into his primal instincts as he faces the harsh realities of survival. His journey leads him to embrace his ancestral heritage as a wolf, which allows him to reconnect with the wild nature that has been dormant within him.

As the story progresses, Buck finds a sense of freedom and fulfillment in the wild that surpasses the comforts of his previous life. The call of the wild becomes a driving force for him, guiding his choices and ultimately leading him to accept his true identity as a creature of nature.
