Answer: a dispute between two camps that was settled by one group moving south to become the Comanche while the other moved west to become the Shoshone.
Explanation:
Dating back to the early 1500s, the Comanche were originally part of the Eastern Shoshone, who lived near the upper reaches of the Platte River in eastern Wyoming. However, when the Europeans entered the scene and the tribe obtained horses, they broke off from the Shoshone with an estimated 10,000 members.
