Answer:
Modern Texas agriculture evolved from the agriculture of prehistoric Texans and agricultural practices transferred from Europe, Asia, and Africa. Crops native to North America included the food staples corn, beans, and squash, and such diverse vegetables as tomatoes, "Irish" potatoes, chili peppers, yams, peanuts, and pumpkins. Spanish colonists introduced wheat, oats, barley, onions, peas, watermelons, and domestic animals, including cattle, horses, and hogs. Prior to European settlement, most of Texas was occupied by nomadic hunting and gathering groups for whom agriculture was peripheral.
