The history of corn major in grains contributing to eradicating the hunger of the world is far more complex than that of what we previously knew. Have you ever wondered where it came from and how it spread in the world?
The process of evacuation of maize (corn) from the forest to the fields began in Mexico about 9000 years ago. Researchers say that a variety of maize varieties, which were partially involved in farming, came in South America even before 6500 years ago and the development of these varieties continued in their own way at both places. Scientists have taken some new results by analyzing the process of inclusion of maize in the field of cultivation and in the field of archaeology.
So far it has been believed that the process of incorporating maize into agriculture has resulted in the Balasas river valley of South Central Mexico. This place is in the south of Mexico City. Later, Maize went from here to other parts of America.
The new discovery reveals that there was no information about this before but another important process for cultivating maize was also carried out. This process took place in the southwestern Amazon area, which expanded to Brazil and Bolivia, and during that time, the process of Mexico was still going on.
Corn become the global crop when the Europeans reached America almost 500 years ago. Other crops grown in the US are potatoes, sweet potatoes, chocolate, tomatoes, peas and avocados. Today, the highest-grown crop in the world is corn. Only 354 million metric tonnes of corn is grown in the United States every year.
Researchers analyzed genomic sequences of 40 modern varieties of corn and 9 archaeological corn samples of about one thousand years, analyzing 68 modern and two ancient genomes of corn, whose knowledge about the genome had been given earlier is.
Logan Kistler, curator of archaeological genome study and archaeological botanical science in the National Museum of Natural History of the Smithsonian Institute in Washington, says, “After the process of incorporation into the cultivation, people can immediately take these crops away in the remote areas Until that time, it was not yet decided in that process that the varieties which are liked by humans Will.” Kistler is the leading author of this research report.
Southwest Amazon already had a major hub of the process of cultivating crops. Meanwhile, corn, partially involved in farming, was brought here. There was a squash, yucca (a South American vegetable) and a local rice farming.
The wild ancestor of corn is a grass called teosinte. Kistler says, “Corn is the most important plant for humans. Every year we grow more than one billion tonnes of corn, with wheat and rice, corn is one of the largest sources of caloric intake throughout the world.”
According to the Kistler, how important is the reason for the human being that it is in the basic events of creation and that it is in the process of incorporating it into farming and it is fulfilled with giving a shape to the life and history of humans.
