Final answer:
The Incas, Mayas, and Aztecs had sophisticated civilizations with complex societies, but did not use wheeled vehicles.
Step-by-step explanation:
The early Central and South American civilizations such as the Incas, Mayas, and Aztecs had complex societies with substantial cities, economies mainly based on agriculture, elaborate religious and cultural systems, and sophisticated political structures. However, these civilizations did not possess the use of wheeled vehicles. The absence of wheeled transportation is particularly noteworthy given the advanced nature of these societies in other areas, such as their monumental architecture, spanning road networks, intricate political hierarchy, and achievements in mathematics and astronomy.
