Mesoamerica—spanning central Mexico through Central America—hosted some of the ancient world's most sophisticated cultures, including the Olmec, Maya, Zapotec, and Aztec civilizations. Their achievements in writing, astronomy, architecture, and agriculture shaped the Americas.
Mesoamerican innovations in mathematics (including the concept of zero), astronomy, and sustainable farming continue to influence modern science and culture. The region's archaeological sites remain vital to understanding human societal development.
