2018年9月20日 · Wild corn (livingcropmuseum.info) Perhaps the most iconic example of selective breeding is North American sweetcorn, which was bred from the barely edible teosinte plant. Natural corn, shown here, was first domesticated in 7,000 BC and was dry like a raw potato, according to this infographic by chemistry teacher James Kennedy.
Maize - Wikipedia
Maize / meɪz / (Zea mays), also known as corn in North American English, is a tall stout grass that produces cereal grain. It was domesticated by indigenous peoples in southern Mexico about 9,000 years ago from wild teosinte. Native Americans planted it alongside beans and squashes in the Three Sisters polyculture.
To Decode the Mystery of Corn, Smithsonian Scientists Recreate Earth as ...
2014年2月11日 · Botanists have debated for nearly a century over the origin of corn, believing at one point that the modern plant was descended from an extinct wild maize, or something yet undiscovered.
Evolution of Corn - University of Utah
Through the study of genetics, we know today that corn's wild ancestor is a grass called teosinte. Teosinte doesn't look much like maize, especially when you compare its kernals to those of corn. But at the DNA level, the two are surprisingly alike.
Wild Grass Became Maize Crop More Than 8,700 Years Ago
2009年3月23日 · The earliest physical evidence for domesticated maize, what some cultures call corn, dates to at least 8,700 calendar years ago, and it was probably domesticated by indigenous peoples in the lowland areas of southwestern Mexico, not the highland areas.
Scientists Trace Corn Ancestry from Ancient Grass to Modern Crop
2005年5月27日 · Researchers have identified corn genes that were preferentially selected by Native Americans during the course of the plant's domestication from its grassy relative, teosinte, (pronounced "tA-O-'sin-tE") to the single-stalked, large-eared plant we know today.
Teosinte - Native-Seeds-Search
Teosinte is an extremely important crop, as it believed that the subspecies parviglumis is the wild progenitor of corn. About 9,000 years ago, teosinte grew wild, as a grass-like plant, with a grain in a tough shell that was dispersed only when ripe.
The Origin of Corn: Unraveling the History of a Staple Crop
2023年8月11日 · What is the Origin of Corn? Teosinte and Corn’s Indigenous Roots in North America. Corn has deep indigenous roots in North America. Teosinte, a wild grass native to Mesoamerica, is considered the ancestor of modern corn [2]. It differs significantly from corn in appearance, with small ears and a tough outer covering.
Numerous theories of origin have been offered over the years, only two of which receive serious con-sideration today. One is that teosinte (Zea mexicana) is the wild progenitor of corn; the other is that a wild pod corn, now extinct, was the ancestor of domesti-cated corn.
Ancient DNA Reveals The Surprisingly Complex Origin Story of Corn
2018年12月13日 · Corn’s Earliest Ancestor By finding evidence of early maize domestication in the southwestern Amazon, scientists have solved one puzzle, but their findings raise new questions. Kistler would like to work backward, using clues from ancient DNA to figure out what the earliest ancestors of modern corn looked like.
