Before the formation of the Grand Canyon, many years ago, a single species of squirrel lived in the area. As the canyon developed, the single species was separated into two habitats, one species on either side of the 10-mile-wide and 1-mile-deep canyon. Evidence also indicates that humans have inhabited the area in recent years. What most likely describes how the formation of the Grand Canyon affected the single squirrel species that once populated the area?
The single species was split into two groups that were geographically isolated by the canyon, with each group adapting to its unique environment.
