The introduction of European livestock—such as cattle, sheep, and horses—to the Americas in the sixteenth century initiated a profound ecological and social transformation. In areas of dense indigenous settlement, grazing animals frequently invaded native cropland, destroying the maize and bean fields that sustained local populations. Yet, many Indigenous societies adapted dynamically to this ecological invasion. On the open grasslands, the adoption of the horse allowed previously sedentary agricultural groups to transition to mobile, equestrian societies, altering patterns of hunting, warfare, and regional trade across the continent.

- BThe development of a politically unified Indigenous alliance across the Great Plains to resist Spanish expansion
- The reorganization of many Indigenous societies' economies and lifestyles to incorporate new domesticated animalsAnswer
