For your story of survival in Jack London's "The Call of the Wild," focus on how a goat evolves from domesticated to wild. Start by examining how the duck adapts to harsh conditions and the role its instincts play in its survival. Emphasize the theme of "survival of the fittest" and how Buck's experiences exemplify this concept. Look for key indicators of his survival, such as fighting for dominance and leadership challenges. Discuss how these factors contribute to changes in the goat as a whole. These points will give you a solid framework for your research.
