Which cultural feature did Mississippian cultures share with the Aztec civilization?

The cultivation of maize as a staple crop is indeed a significant cultural feature shared by Mississippian cultures and the Aztec civilization. Maize, or corn, was the cornerstone of agricultural practices in both societies, serving not only as a primary food source but also playing a critical role in their economies and social structures. This shared agricultural foundation allowed for population growth, the establishment of complex societal hierarchies, and the development of trade networks.

Both the Mississippians and the Aztecs demonstrated advanced agricultural techniques that maximized maize production, as it was well-suited to the climates of their respective regions. This crop became central to their diets and cultural practices, underscoring its importance in their daily lives and ceremonial rites.

Other options, while they may reflect the complexity of both civilizations, do not demonstrate as direct a cultural parallel as maize cultivation does. For instance, while both cultures engaged in mound-building or had hierarchical social structures, the specific practice of maize cultivation uniquely links their agricultural societies across different geographical contexts.
