The domestication and development of corn in and of itself causes much argument it is because of great archeologists like macneish and his firm wonder of the great maize hunt as to why we have the information that we have today. Maize was domesticated from its wild grass ancestor more than 8,700 years ago, according to biological evidence uncovered by researchers in mexico's central balsas river valley this is the earliest dated evidence — by 1,200 years — for the presence and use of domesticated maize. Domestication history scholars are not completely in agreement that the closest wild garlic to the current domesticated variety is allium longicuspis for example, mathew et al argue that since a longiscuspis is sterile, it can't be the wild ancestor, but rather a cultivated plant abandoned by nomads. The earliest events in maize domestication likely involved small changes to single genes with dramatic effects we know the events were early because there is little variation in these genes between maize varieties, suggesting that modern varieties are descended from a single ancestor. Domestication of sugarcane occurred in southeast asia early cultivators discovered that the stem was a rich source of sugar and high in caloric value bamboo is an overlooked but remarkably useful crop.
The domestication of corn has long fascinated biologists studying evolution corn can provide clues to how organisms change under selection — whether it's natural selection or selection by humans choosing the most delicious and productive plants to grow in next year's crop. 5000-year-old cobs reveal corn domestication in the act by jessica boddy nov 21, 2016 , 3:00 pm it wasn't easy to make a meal of teosinte, a grass that was the ancient precursor to maize.

Scientists are using new genetic and microbotanical techniques to distinguish domesticated maize from its wild relatives as well as to identify ancient sites of maize agriculture these new. While american indians raised a great many different crops, one of the important plants was maize (zea mays), often called corn in american english in addition to maize, american indians had also domesticated numerous other plants, including beans, squash, chili peppers, avocados, cotton, and others.
By simulating the environment when corn was first exploited by people and then domesticated, smithsonian scientists discovered that corn's ancestor, a wild grass called teosinte, may have looked. Corn as modern people know it - be it popped, boiled, grilled, or fried - looks vastly different from its ancestors' corn the discoveries of dr wales and his team of scientists provide a unique link in the 10,000-year chain of corn evolution and domestication. The popcorn variety of maize was domesticated by pre-columbian indigenous peoples by 5000 bce it is a small and harder form of flint corn, most commonly found in white or yellow kernels.
By simulating the environment when corn was first exploited by people and then domesticated, smithsonian scientists discovered that corn's ancestor a wild grass called teosinte, may have looked. Corn was domesticated in mexico around 9,000 years ago from the wild grass teosinte teosinte seeds are protected by a hard casing that makes them impractical to eat, but ancient plant breeders. Evolution of maize agriculture corn or maize (zea mays) is a domesticated plant of the americas along with many other indigenous plants like beans, squash, melons, tobacco, and roots such as jerusalem artichoke, european colonists in america quickly adopted maize agriculture from native americans. The process of maize domestication radically changed it from its origins the seeds of wild teosinte are encased in hard shells and arranged on a spike with five to seven rows, a spike that shatters when the grain is ripe to disperse its seed modern maize has hundreds of exposed kernels attached to.
