Over 9,000 years ago in Mexico, ancient people domesticated corn and developed basic calendars for farming, leading to the first civilizations in North America. Many advanced civilizations developed across North America, including the Olmec in Mexico around 1800 BC, the Teotihuacan in Mexico from around 200 BC to 650 AD with a population of around 200,000, and the widespread Maya civilization from 1000 BC to 1540 AD across Mexico and Central America. Native Americans built large earthwork mounds and pyramid structures from Louisiana to Wisconsin as part of the Mississippian civilization from around 800-1500 AD, demonstrating their advanced achievements.
