Answer:
Before Europeans arrived in North America, Native American groups developed into distinct and complex societies in response to the unique environments they inhabited.
Step-by-step explanation:

They farmed corn, hunted, and gathered, establishing diverse lifestyles and healthy diets.
When horses arrived on the Plains along with the Spanish colonizers, or conquistadores, they disrupted agricultural norms and intensified hunting competition between Native American groups.
