Final answer:
The outcome of the duels between the twins on the turtle's back is not specified in the provided text excerpts. Indigenous creation stories, which feature these duels, are valuable for their cultural, ethical, and natural explanations rather than focusing on a single victor.
Step-by-step explanation:
The outcome of the duels between the twins in the world on the turtle's back, which originates from an Indigenous creation story of the Eastern Woodlands, isn't explicitly mentioned in the provided text excerpts. However, Indigenous origin stories such as these often have significant cultural and symbolic meaning within the respective communities, where aspects like the turtle represent life. In many Indigenous cultures, stories are a way of explaining natural phenomena, ethics, and the creation of the world; they're not always structured around winners and losers as in Western narratives, which is exemplified in lore regarding cosmic or primal battles and creations such as found on the turtle's back. Observing the provided references, none outline the duel's outcome between the twins.
Given the traditional nature of these stories, the duels are likely to represent some form of balance or teaching rather than a single victorious outcome. It's important to understand these narratives within their cultural context to grasp their full significance. Students should explore these cultural stories in their entirety to understand the outcomes and morals they teach.
