Which long-term consequence developed because raised chinampa field systems affected the local environment?

💡 Explanation

Chinampas caused in situ selective pressure through continuous cultivation, which encouraged the selection of specific genetic traits in maize, eventually leading to unique landraces because the artificial wetlands had elevated humidity rather than typical arid conditions; therefore, understanding this pre-Columbian cultivation method is important.
