Corn also known as Zea mays in its scientific name is an essential cereal that is believed to have originated from the Western Hemisphere. Many people believe that corn originated from the Mexico and southern Argentina while others suggest its origin as the valleys of Mexico. Many theories of its origin have been created, only two of them get serious consideration nowadays. The first one is the teosinte theory of the wild progenitor of corn. The other is the theory of the wild pod corn that is now extinct. The theory suggested that corn was domesticated by ancestors. Many scholars and students accept the first theory, but others are equally convinced that the second is right. Apart from its possible position in the origin of corn, the first theory has had significant impact on its evolution. Specifically in Mexico, introgression between teosinte and corn has mostly occurred for many years and is continuous to this day (Peckham, 2001).
The effects are not real in the cytology and morphology of both species. There exists a reason to accept that genes for resistance to particular viruses have brought corn to its introgression with teosinte. Origin of corn might never be clearly known with certainty. A major reason is that the suggestion purporting to explain the origin cannot be tested through experiments. Therefore, science may perhaps be better used if less attention is accorded to determine the origin of corn and more to comprehension of the variability existing within the species (Murray, 2007).
Regardless of its origin, corn has proved to be
