WORLD HISTORY

Detailed explanation-1: -Teosintes are native to Mexico, Guatemala, Honduras, and Nicaragua. Domesticated corn, or maize (Zea mays mays), was derived from the Balsas teosinte (Z. mays parviglumis) of southern Mexico in pre-Columbian times more than 6, 000 years ago. Teosintes are solitary (single-stalked) annuals or spreading perennials.

Detailed explanation-2: -Maize (Zea mays mays) was domesticated from its wild relative teosinte about 9, 000 years ago in southern Mexico13.

Detailed explanation-3: -The botanical name of Teosinte is Euchaleanamaxicana and it is commonly known as Makchari.

Detailed explanation-4: -The primary centre of origin of maize is considered by most authorities to be the Central America and Mexico, where many diverse types of maize are found. The discovery of fossil maize pollen with other archaeological evidence in Mexico indicates Mexico to be the native of maize.

Detailed explanation-5: -Through the study of genetics, we know today that corn’s wild ancestor is a grass called teosinte.

Detailed explanation-6: -Teosintes are several wild species of grass in the genus Zea which are critical components of maize evolution.
