How did previous civilizations influence the development of the Mayan Aztecs and incas?

Previous civilizations, such as the Olmecs and Teotihuacan in Mesoamerica, significantly influenced the development of the Maya and Aztec cultures through advancements in agriculture, urban planning, and religious practices. The Olmecs are often considered the "mother culture" of Mesoamerica, contributing to the development of writing, art, and monumental architecture that the Maya later adopted and adapted. Similarly, the Inca civilization drew inspiration from earlier Andean cultures, incorporating agricultural techniques, road systems, and social organization that facilitated their expansion and administration. These interactions and adaptations helped shape the unique identities and achievements of the Maya, Aztecs, and Incas.
