What lesson about strength and survival does Buck learn in the wild?

Buck's journey in "The Call of the Wild" highlights the harsh realities of survival in the wilderness, where he learns that ultimately, every creature must fend for itself. This lesson becomes evident as he navigates the challenges of a ruthless environment, where instincts take precedence over any previous bonds or comforts he experienced as a domesticated dog.

As he adapts to his new surroundings, Buck discovers that the law of the wild emphasizes individual strength and self-reliance. While companionship and teamwork may play roles at times, the brutal competition for resources and survival underscores the idea that one must be prepared to rely solely on their own abilities. This transformation marks Buck's evolution from a pampered pet to a creature in tune with primal instincts, reinforcing the notion that in the wild, survival is ultimately an individual endeavor.
