Why did people in the early americas not use the wheel?

c. there were no large animals to pull wagons.

d. anything circular was viewed as an omen of bad luck.

The correct option is "a. They failed to invent the wheel."

In America The absence of pack animals, the absence of navigable rivers of importance as well as the predominantly north-south configuration of the American continent hindered the integration of large areas of the continent into extensive states and limited contacts between the different cultures that emerged. The pre-Columbian man, developed techniques of cultivation, irrigation and transport of cargo, but did not develop the wheel.
