Question: Where did maize cultivation begin in the region where Anglo-America is located?

full_context: Document 1: Maize: An influential 2002 study by Matsuoka et al. has demonstrated that, rather than the multiple independent domestications model, all maize arose from a single domestication in southern Mexico about 9,000 years ago. The study also demonstrated that the oldest surviving maize types are those of the Mexican highlands. Later, maize spread from this region over the Americas along two major paths. This is consistent with a model based on the archaeological record suggesting that maize diversified in the highlands of Mexico before spreading to the lowlands.
Document 2: Corn production in the United States: Iowa, the largest producer of corn in the US, grows three times as much corn as Mexico. Iowa harvested 3,548 acres (1,436 ha) of sweet corn in 2007. In 2011, the state had 92,300 corn farms on 30,700,000 acres (12,400,000 ha), the average size being 333 acres (135 ha), and the average dollar value per acre being US $6,708. In the same year, there were 13.7 million harvested acres of corn for grain, producing 2.36 billion bushels, which yielded 172.0 bu / acre, with US $14.5 billion of corn value of production. Almost 1.88 billion bushels of corn were grown in the state in 2012 on 13.7 million acres of land, while the 2013 projections are 2.45 billion bushels of corn on 13.97 million acres of land.
Document 3: South America: The continent's cultural and ethnic outlook has its origin with the interaction of indigenous peoples with European conquerors and immigrants and, more locally, with African slaves. Given a long history of colonialism, the overwhelming majority of South Americans speak Portuguese or Spanish, and societies and states commonly reflect Western traditions.
Document 4: Indigenous peoples of the Americas: According to both indigenous American and European accounts and documents, American civilizations at the time of European encounter had achieved many accomplishments. For instance, the Aztecs built one of the largest cities in the world, Tenochtitlan, the ancient site of Mexico City, with an estimated population of 200,000. American civilizations also displayed impressive accomplishments in astronomy and mathematics. The domestication of maize or corn required thousands of years of selective breeding.
Document 5: Hushpuppy: The use of ground corn (maize) in cooking originated with Native Americans, who first cultivated the crop. Cherokee, Chickasaw, Choctaw, Creek, and Seminole cooking introduced one of its main staples into Southern cuisine: corn, either ground into meal or limed with an alkaline salt to make hominy, in a Native American technology known as nixtamalization. Cornbread was popular during the American Civil War because it was very cheap and could be made in many different sizes and forms. It could be fashioned into high - rising, fluffy loaves or simply fried for a quick meal.
Document 6: Indigenous peoples of the Americas: Many crops first domesticated by indigenous Americans are now produced and used globally. Chief among these is maize or "corn", arguably the most important crop in the world. Other significant crops include cassava, chia, squash (pumpkins, zucchini, marrow, acorn squash, butternut squash), the pinto bean, Phaseolus beans including most common beans, tepary beans and lima beans, tomatoes, potatoes, avocados, peanuts, cocoa beans (used to make chocolate), vanilla, strawberries, pineapples, Peppers (species and varieties of Capsicum, including bell peppers, jalapeños, paprika and chili peppers) sunflower seeds, rubber, brazilwood, chicle, tobacco, coca, manioc and some species of cotton.
Document 7: English language: English is a West Germanic language that was first spoken in early medieval England and is now a global lingua franca. Named after the Angles, one of the Germanic tribes that migrated to England, it ultimately derives its name from the Anglia (Angeln) peninsula in the Baltic Sea. It is closely related to the Frisian languages, but its vocabulary has been significantly influenced by other Germanic languages, particularly Norse (a North Germanic language), as well as by Latin and Romance languages, especially French.
Document 8: Maize: Maize (/ meɪz / MAYZ; Zea mays subsp. mays, from Spanish: maíz after Taino: mahiz), also known as corn, is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences and separate ovuliferous inflorescences called ears that yield kernels or seeds, which are fruits.
Document 9: Race (human categorization): The term "Hispanic" as an ethnonym emerged in the 20th century with the rise of migration of laborers from the Spanish-speaking countries of Latin America to the United States. Today, the word "Latino" is often used as a synonym for "Hispanic". The definitions of both terms are non-race specific, and include people who consider themselves to be of distinct races (Black, White, Amerindian, Asian, and mixed groups). However, there is a common misconception in the US that Hispanic/Latino is a race or sometimes even that national origins such as Mexican, Cuban, Colombian, Salvadoran, etc. are races. In contrast to "Latino" or "Hispanic", "Anglo" refers to non-Hispanic White Americans or non-Hispanic European Americans, most of whom speak the English language but are not necessarily of English descent.
Document 10: Bermuda: Bermuda's culture is a mixture of the various sources of its population: Native American, Spanish-Caribbean, English, Irish, and Scots cultures were evident in the 17th century, and became part of the dominant British culture. English is the primary and official language. Due to 160 years of immigration from Portuguese Atlantic islands (primarily the Azores, though also from Madeira and the Cape Verde Islands), a portion of the population also speaks Portuguese. There are strong British influences, together with Afro-Caribbean ones.
Document 11: Indigenous peoples of the Americas: Over the course of thousands of years, American indigenous peoples domesticated, bred and cultivated a large array of plant species. These species now constitute 50–60% of all crops in cultivation worldwide. In certain cases, the indigenous peoples developed entirely new species and strains through artificial selection, as was the case in the domestication and breeding of maize from wild teosinte grasses in the valleys of southern Mexico. Numerous such agricultural products retain their native names in the English and Spanish lexicons.
Document 12: Latin America: Latin America is a group of countries and dependencies in the Western Hemisphere where Spanish, French and Portuguese are spoken; it is broader than the terms Ibero - America or Hispanic America. The term originated in the Napoleon III French government in the mid-19th century as Amérique latine to consider French - speaking territories in the Americas, (French Canadians, French Louisiana, French Guiana, Haiti, Guadeloupe, Martinique, Saint Martin, Saint Barthélemy) along with the larger group of countries where Spanish and Portuguese languages prevailed, including the Spanish - speaking portions of the United States (the Southwest and Florida.) Today, areas of Canada and the United States (with the exception of Puerto Rico and Miami) where Spanish, Portuguese and French are predominant are typically not included in definitions of Latin America.
Document 13: Languages of the United States: Many languages are spoken, or historically have been spoken, in the United States. Today over 500 languages are used by the U.S. population. The most commonly used language is English (specifically, American English), which is the de facto national language of the United States. Since the 1965 Immigration Act, Spanish is the second most common language in the country. The United States does not have an official language, but some state governments recognize specific languages. For instance, the state government of Louisiana offers services and documents in French, as does New Mexico in Spanish. There are many languages indigenous to North America or to U.S. states or holdings in the Pacific region. Hawaiian, although having few native speakers, is an official language along with English of the state of Hawaii. Alaska officializes English and twenty native languages.
Document 14: Anglo-America: Anglo-America (also referred to as Anglo-Saxon America) most often designates to a region in the Americas in which English is a main language and British culture and the British Empire have had significant historical, ethnic, linguistic and cultural impact. Anglo-America is distinct from Latin America, a region of the Americas where Romance languages (Spanish, Portuguese and French) are prevalent.
Document 15: History of England: The end of Roman rule in Britain facilitated the Anglo - Saxon settlement of Britain, which historians often regard as the origin of England and of the English people. The Anglo - Saxons, a collection of various Germanic peoples, established several kingdoms that became the primary powers in present - day England and parts of southern Scotland. They introduced the Old English language, which largely displaced the previous British language. The Anglo - Saxons warred with British successor states in Wales, Cornwall, and the Hen Ogledd (Old North; the Brythonic - speaking parts of northern England and southern Scotland), as well as with each other. Raids by Vikings became frequent after about AD 800, and the Norsemen settled in large parts of what is now England. During this period, several rulers attempted to unite the various Anglo - Saxon kingdoms, an effort that led to the emergence of the Kingdom of England by the 10th century.
