History of corn

Teocintle

The Teocintle

Here we have a types of corn.

Most researchers believe that this cereal was developed from teosinte, Euchlaena Mexican Schrod, annual plant that is possibly the closest to corn. The thesis of the proximity between teosinte and maize is based on both have 10 chromosomes and are homologous or partially homologous. In the 80s, Iltis proposes a theory which states that teosinte corn became one evolutionary step.

The sugar-rich varieties, called sweet corn are generally grown for human consumption as grain, while field corn varieties are used for animal feed, the development of derivatives for human consumption

Andean Corn

Andean origin

Conclusion

Corn would have originated in the high Andes of Bolivia, Ecuador and Peru (Mangelsdorf and Reeves, 1959) and the conclusions of the studies of Thomas Lynch Cornell University and other researchers, who conclude that the corn from 6,200 B.C. It is present in the Cave Guitarrero province of Yungay, Peru. One justification for this hypothesis is the broad genetic diversity present in Andean corns, especially in the highlands of Peru. A serious objection to this hypothesis is that no wild relative of maize is not known, including teosinte, in that region (Wilkes, 1989). In recent years, Mangelsdorf ruled out the hypothesis of Andean origin.

Maize in Guatemala is a great source of the national economy, since it is one of the products based on the basic basket; by that reason is good that is celebrate a day in honor to the corn because from the beginning it Mayan you rendered cult and it believed a fruit sacred of the nature.

Is good that them generations new is soak of all that knowledge by which know more than our large and extensive history and know of where come, which is our culture and not let us influence by the cultures of another country.

The origin of Corn

Asian origin

The origin of corn place is located in the Coxcatlán, in the Valley of Tehuacan, Puebla, in central Mexico. This valley is characterized by dry climate, with an average annual rainfall greatly reduced; mainly houses and plant species typical of hot and dry land animals. The region has numerous endemic species, making it a unique territory. "The American anthropologist Richard Stockton MacNeish found archaeological remains of corn plants, estimated to date back approximately eight millennia. Signs of the processes that led to native people of this valley to master the cultivation of this cereal, have been found in the cave Coxcatlán, Ajalpan and other sites in the area.

Corn in Asia

Corn may have originated in the Himalayan region, the product of a cross between Coix spp. And some Andropogóneas probably Sorghum species, both parents with five pairs of chromosomes (Anderson, 1945). This theory has not had great support.

Comes from a wild Corn

Corn

Some researchers speculate that originated from an ancient, now extinct, wild form of native maize in the highlands of Mexico or Guatemala. It was suggested that the ancestors of cultivated maize were some form of wild corn. Primitive corn, teosinte and Tripsacum diverged among them many thousands of years before the wild maize evolved to become a cultivated plant. As have never found wild maize or wild forms of maize plants, this theory does not receive much consideration

A few synonims of corn are:
