How Maize Transformed Life in the Americas — Reading Comprehension

Maize, known today as corn, became one of the most important crops in the history of the Americas. Its domestication and spread shaped the development of ancient American civilizations, such as the Olmec, Maya, and Aztec. The process of transforming wild grasses into a reliable food source began over 9,000 years ago in what is now southern Mexico.

The earliest archaeological evidence of maize comes from the site of Guilá Naquitz in Oaxaca, Mexico, dating back to around 6700 BCE. Early farmers noticed that some wild grasses, called teosinte, produced larger seeds. By carefully selecting seeds from these plants, people gradually cultivated maize that was easier to harvest and provided more food. This process, known as domestication, allowed communities to produce food in greater quantities. As maize farming spread north and south, it appeared in places like the southwestern United States by 2100 BCE and in Peru by 3000 BCE.

The rise of maize agriculture led to major changes in society. Communities could store surplus food, which supported growing populations and the development of urban centers. The Olmec civilization, often called the "mother culture" of Mesoamerica, built large ceremonial centers like San Lorenzo (c. 1200 BCE), where maize was a main food. Later, the Maya relied on maize to support their city-states, such as Tikal and Copán. The Aztec, in central Mexico, even created floating gardens called chinampas to grow maize on lakes, demonstrating complex engineering skills. Maize also played a central role in religion and mythology. Maya texts, like the Popol Vuh, describe humans as being made from maize.

The impact of maize went beyond food. Surplus harvests led to specialization of labor, as not everyone needed to farm. Some people became artisans, traders, or priests, leading to social hierarchy and more complex societies. Maize allowed for trade networks, as evidence from pottery and tools shows the movement of goods between regions. Over time, maize agriculture continued to shape the environment, as farmers adapted to different ecosystems across the Americas.

In conclusion, maize was more than just a crop; it was a foundation for civilization in the ancient Americas. Its domestication enabled the growth of powerful societies, influenced religious beliefs, and transformed daily life. The story of maize connects to broader themes of human adaptation, technological innovation, and the relationship between geography and culture.
