Here's how they contribute to the story:
* The Catalyst for Buck's Transformation: The Yeehats are responsible for stealing Buck and bringing him into the wilderness. This event marks the beginning of Buck's journey from domesticated dog to wild animal, as he must learn to survive and fend for himself in a harsh and unforgiving environment.
* Symbol of the Primitive World: The Yeehats represent the primitive, untamed forces of nature that Buck must confront. Their presence constantly reminds him of the dangers of the wild and the need to rely on his primal instincts.
* The Antagonists: They are the direct antagonists for Buck and the other dogs in the story. They hunt them for food and sport, and their presence is a source of constant fear and tension.
* The Driving Force of the Plot: The Yeehats' attacks and their pursuit of Buck are crucial to the plot's progression. They force Buck to adapt to the wild, develop his leadership skills, and ultimately embrace his primal instincts.
While the portrayal of the Yeehats is often criticized for its stereotypical and racist depictions, it's important to remember that the story was written in the early 20th century and reflects the social and cultural views of that time.
It's essential to analyze the Yeehats' role in *The Call of the Wild* within this historical context, recognizing both the story's literary merit and its problematic elements.
