Using LiDAR technology, archaeologists in the Oaxaca region of Mexico have identified a massive 2,500-year-old complex dedicated to botanical research and agricultural experimentation. The site features hundreds of artificial terraces, a sophisticated irrigation network, and specialized pits containing the charred remains of medicinal plants and early corn varieties.
Researchers believe this 'Green Citadel' was the primary center for Zapotec plant domestication, where the ancient civilization developed drought-resistant crops through careful cross-breeding. The discovery reshapes our understanding of Mesoamerican science, proving that the Zapotec were not just builders and warriors, but pioneers in environmental management and agricultural genetics.
